                               SEPTEMBER 14, 1999

Dear Stockholders:

   I am pleased to inform you that on September 7, 1999, Applied Digital
Access, Inc. ("ADA") entered into an Agreement and Plan of Merger with Dynatech
Corporation ("Dynatech"). Pursuant to this merger agreement, a subsidiary of
Dynatech is commencing a cash tender offer to purchase all of the outstanding
shares of ADA's Common Stock at a price of $5.37 per share. Following
completion of the tender offer, upon the terms and subject to the conditions of
the merger agreement, the Dynatech subsidiary will be merged with and into ADA,
and each share of ADA Common Stock not purchased in the tender offer (other
than any shares owned by any dissenting stockholders) will be converted into
the right to receive $5.37 per share in cash, without interest. Upon
consummation of these transactions, Dynatech and its affiliates will own the
entire equity interest in ADA.

   The board of directors of ADA has determined that the tender offer and the
merger are fair to and in the best interests of ADA stockholders and has
unanimously approved the merger agreement and the transactions contemplated
thereby, including the tender offer and the merger, and unanimously recommends
that the stockholders of ADA accept the Dynatech tender offer and tender their
shares thereunder.

   Accompanying this letter, in addition to the attached Schedule 14D-9
relating to the tender offer, is the Offer to Purchase, dated September 14,
1999, of the Dynatech subsidiary making the tender offer together with related
materials including a Letter of Transmittal to be used for tendering your
shares. These documents set forth the terms and conditions of the offer and the
merger, provide detailed information about the transactions and include
instructions as to how to tender your shares. I urge you to read the enclosed
materials carefully.

                                          Very truly yours

                                          /s/ Donald L. Strohmeyer

                                  INTRODUCTION

   This Solicitation/Recommendation Statement on Schedule 14D-9 (this "Schedule
14D-9") relates to an offer by Dynatech Corporation, a Delaware corporation
("Dynatech" or "Parent"), through its indirect wholly owned subsidiary Dynatech
Acquisition Corporation, a Delaware corporation ("Purchaser"), to purchase all
of the Shares (as defined below) of Applied Digital Access, Inc., a Delaware
corporation.

ITEM 1. SECURITY AND SUBJECT COMPANY

   The name of the subject company is Applied Digital Access, Inc., a Delaware
corporation (the "Company"). The address of the principal executive office of
the Company is 9855 Scranton Road, San Diego, California 92121. The title of
the class of equity securities to which this Schedule 14D-9 relates is the
common stock of the Company, par value $0.001 per share (the "Shares").

ITEM 2. TENDER OFFER OF THE BIDDER

   This Schedule 14D-9 relates to the tender offer (the "Offer") disclosed in
the Schedule 14D-1, dated September 14, 1999 (as amended or supplemented, the
"Schedule 14D-1"), filed with the Securities and Exchange Commission (the
"Commission") by Dynatech and Purchaser, relating to an offer by the Purchaser
on behalf of Dynatech, to purchase all outstanding Shares at a price of $5.37
per Share, net to the seller in cash, without interest thereon (the "Offer
Price"), upon the terms and subject to the conditions set forth therein. The
principal executive offices of each of Parent and the Purchaser are located at
3 New England Executive Park, Burlington, Massachusetts 01803.

   The Offer is being made pursuant to an Agreement and Plan of Merger dated as
of September 7, 1999 (the "Merger Agreement") by and among the Company, Parent
and the Purchaser. A copy of the Merger Agreement is filed as Exhibit (4) to
this Schedule 14D-9 and is hereby incorporated by reference. The Merger
Agreement provides that, among other things, as soon as practicable after the
purchase of Shares validly tendered and not withdrawn pursuant to the Offer,
and the satisfaction of the other conditions set forth in the Merger Agreement,
and in accordance with the relevant provisions of the General Corporation Law
of the State of Delaware ("Delaware Law" or the "DGCL"), Purchaser will be
merged with and into the Company (the "Merger"). Following consummation of the
Merger, the Company will continue as the surviving corporation (the "Surviving
Corporation") and will become an indirect wholly owned subsidiary of Parent. At
the effective time of the Merger (the "Effective Time"), each Share issued and
outstanding immediately prior to the Effective Time (other than Shares held by
the Company or by any subsidiary of the Company, or owned by the Purchaser, by
Parent, or any other subsidiary of Parent or Shares held by stockholders who
shall have demanded and perfected appraisal rights, if any, under Delaware Law)
will be canceled and converted automatically into the right to receive the
price per Share paid pursuant to the Offer in cash, without interest (the
"Merger Consideration"). The Merger Agreement is summarized in Item 3 of this
Schedule 14D-9. Although Dynatech is offering to purchase the Shares through
Purchaser, Dynatech has agreed to take all action necessary to cause Purchaser
to fulfill all its obligations with respect to the Offer and otherwise under
the Merger Agreement, including without limitation the obligation to make
payment for the Shares.

ITEM 3. IDENTITY AND BACKGROUND

   (a) The name and business address of the Company, which is the person filing
this Schedule 14D-9, are set forth in Item 1 above. Unless the context
otherwise requires, references to the Company in this Schedule 14D-9 are to the
Company and its subsidiaries, viewed as a single entity.

   (b) Except as set forth below, to the Company's knowledge, as of the date
hereof, there are no material contracts, agreements, arrangements or
understandings and actual or potential conflicts of interest between the
Company or its affiliates and (i) its executive officers, directors or
affiliates, or (ii) Parent, Purchaser or their respective executive officers,
directors or affiliates.

     (1) Certain Contracts, Agreements, Arrangements or Understandings
  Between the Company and its Executive Officers, Directors and Affiliates.

   Certain contracts, agreements, arrangements or understandings between the
Company or its affiliates and certain of its executive officers, directors or
affiliates are described in the Information Statement of the Company attached
to this Schedule 14D-9 as Annex A (the "Information Statement"). The
Information Statement is being furnished to the Company's shareholders pursuant
to Section 14(f) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), and Rule 14f-1 issued under the Exchange Act in connection
with Parent's rights (upon the acquisition by Purchaser of Shares pursuant to
the Offer) to designate persons to be appointed by the Board of Directors of
the Company (the "Company Board") without a meeting of the stockholders of the
Company. The Information Statement is incorporated herein by reference.
Stockholders should be aware that certain members of the Company's Board of
Directors, management and other employees of the Company have interests in the
Merger in addition to the interests of the stockholders of the Company in
general, as described further below and in the Information Statement.

INDEMNIFICATION

   Section 145 of the Delaware General Corporation Law permits indemnification
of officers and directors of the Company under certain conditions and subject
to certain limitations. Section 145 of the Delaware General Corporation Law
also provides that a corporation has the power to purchase and maintain
insurance on behalf of its officers and directors against any liability
asserted against such person and incurred by him or her in such capacity, or
arising out of his or her status as such, whether or not the corporation would
have the power to indemnify him or her against such liability under the
provisions of Section 145 of the Delaware General Corporation Law.

   Article VII, Section 1 of the Bylaws of the Company provides that the
Company shall indemnify its directors and executive officers to the fullest
extent not prohibited by the Delaware General Corporation Law. The rights to
indemnity thereunder continue as to a person who has ceased to be a director,
officer, employee or agent and inure to the benefit of the heirs, executors and
administrators of the person. In addition, expenses incurred by a director or
executive officer in defending any civil, criminal, administrative or
investigative action, suit or proceeding by reason of the fact that he or she
is or was a director or officer of the Company (or was serving at the Company's
request as a director or officer of another corporation) shall be paid by the
Company in advance of the final disposition of such action, suit or proceeding
upon receipt of an undertaking by or on behalf of such director or officer to
repay such amount if it shall ultimately be determined that he or she is not
entitled to be indemnified by the Company as authorized by the relevant section
of the Delaware General Corporation Law.

   As permitted by Section 102(b)(7) of the Delaware General Corporation Law,
Article V, Section (A) of the Company's Certificate of Incorporation provides
that a director of the Company shall not be personally liable for monetary
damages for breach of fiduciary duty as a director, except for liability (i)
for any breach of the director's duty of loyalty to the Company or its
stockholders, (ii) for acts or omissions not in good faith or acts or omissions
that involve intentional misconduct or a knowing violation of law, (iii) under
Section 174 of the Delaware General Corporation Law or (iv) for any transaction
from which the director derived any improper personal benefit.

   The Company has entered into indemnification agreements with each of its
directors and executive officers. Generally, the indemnification agreements
attempt to provide the maximum protection permitted by Delaware law as it may
be amended from time to time. Moreover, the indemnification agreements provide
for certain additional indemnification. Under such additional indemnification
provisions, however, an individual will not receive indemnification for
judgments, settlements or expenses if he or she is found liable to the Company
(except to the extent the court determines he or she is fairly and reasonably
entitled to indemnity for expenses), for settlements not approved by the
Company or for settlements and expenses if the settlement is not approved by
the court. The indemnification agreements provide for the Company to advance to
the individual

                                       2
<PAGE>

any and all reasonable expenses (including legal fees and expenses) incurred in
investigating or defending any such action, suit or proceeding. In order to
receive an advance of expenses, the individual must submit to the Company
copies of invoices presented to him or her for such expenses. Also, the
individual must repay such advances upon a final judicial decision that he or
she is not entitled to indemnification. The Company has purchased directors'
and officers' liability insurance.

   Mr. James L. Keefe, currently Vice President, Finance and Administration,
Chief Financial Officer and Secretary of the Company, has tendered his
resignation effective September 15, 1999. Thereafter, and through the
consummation of the Merger, Mr. Keefe will serve as a consultant to the
Company. Pursuant to the terms of Mr. Keefe's consulting arrangement, Mr.
Keefe's outstanding options to purchase Common Stock of the Company will
continue to vest through the Merger and will accelerate upon the consummation
of the Merger, pursuant to the terms of the Merger Agreement.

   Pursuant to the terms of the Merger Agreement, as more fully described
below, and as set forth in Annex A, all options, including those options held
by directors and executive officers of the Company, outstanding at the
consummation of the Merger, whether or not then exercisable, shall be canceled
by the Company in exchange for the right to receive the Option Consideration.

   Certain employees of the Company may enter into agreements with the Company
regarding their employment after the completion of the Merger.

     (2) Certain Contracts, Agreements, Arrangements or Understandings
  Between the Company and Parent, Purchaser or the Executive Officers,
  Directors and Affiliates of Parent or Purchaser.

THE MERGER AGREEMENT

   The following summary of certain provisions of the Merger Agreement is
presented only as a summary and is qualified in its entirety by reference to
the Merger Agreement, a copy of which is filed as Exhibit (4) to this Schedule
14D-9.

   The Merger Agreement provides that following the satisfaction or waiver of
the conditions described below under "Conditions to the Merger", the Purchaser
will be merged with and into the Company, and each then outstanding Share
(other than Shares owned by the Company, any subsidiary of the Company, Parent,
the Purchaser, any other subsidiary of Parent or by stockholders, if any, who
are entitled to and who properly exercise appraisal rights under Delaware law)
will be converted into the right to receive an amount in cash equal to the
price per Share paid pursuant to the Offer.

   The Offer. The Merger Agreement provides for the commencement of the Offer
no later than five business days after the public announcement of the execution
of the Merger Agreement. The Purchaser has agreed in the Merger Agreement that
it will not, without the written consent of the Company, reduce the price per
Share or the number of Shares sought to be purchased, or modify the form of
consideration to be received by holders of the Shares in the Offer, decrease,
increase or waive the Minimum Condition (as defined below), impose additional
conditions to the Offer or amend any term of the Offer in a manner materially
adverse to the holders of the Shares. The Offer is conditioned upon, among
other things, (i) there being validly tendered and not withdrawn prior to the
expiration date of the Offer at least that number of Shares that would
represent in excess of 50% of all outstanding Shares determined on a fully
diluted basis (such basis assumes all Shares underlying in-the-money vested and
unvested stock options are outstanding) on the date of purchase (the "Minimum
Condition") and (ii) any waiting period under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended (the "HSR Act"), and the regulations
thereunder applicable to the purchase of Shares pursuant to the Offer having
expired or been terminated.

   The obligation of the Purchaser to accept for payment and pay for Shares
tendered pursuant to the Offer is subject to certain conditions. The Purchaser
has agreed to accept for payment and pay for any and all Shares

                                       3
<PAGE>

validly tendered as promptly as practicable after the satisfaction or waiver of
the conditions to the Offer; provided that, if, immediately prior to the latest
expiration date of the Offer permitted by the Merger Agreement, the number of
Shares validly tendered and not withdrawn pursuant to the Offer is less than
90% of the outstanding Shares, the Purchaser shall have the right to extend the
Offer without the consent of the Company (for not more than an aggregate of ten
business days) in order to permit the Purchaser to solicit the tender of
additional Shares pursuant to the Offer.

   Vote Required to Approve Merger. The DGCL requires, among other things, that
the adoption of any plan of merger or consolidation of the Company must be
approved by the Board of Directors and generally by the holders of the
Company's outstanding voting securities. The Board of Directors of the Company
has approved the making of the Offer and the Merger; consequently, the only
additional action of the Company that may be necessary to effect the Merger is
approval by the Company's stockholders if the "short-form" merger procedure
described below is not available. Under the DGCL, the affirmative vote of
holders of a majority of the voting power of the then outstanding Shares
(including any Shares owned by the Purchaser) is generally required to approve
the Merger. If the Purchaser acquires, through the Offer or otherwise, a
majority of the voting power of the outstanding Shares (which would be the case
if the Minimum Condition were satisfied and the Purchaser were to accept for
payment Shares tendered pursuant to the Offer), it would have sufficient voting
power to effect the Merger without the vote of any other stockholder of the
Company.

   Under the DGCL, if a corporation owns 90% or more of each outstanding class
of capital stock of another corporation, it can effect a "short-form" merger
with such corporation without prior notice to, or any other action by, any
other stockholder of such corporation. As a result, assuming no Stock Options
are exercised following September 7, 1999, if the Purchaser were to acquire
ownership of 11,913,912 Shares pursuant to the Offer, the Purchaser would own
more than 90% of the only class of capital stock of the Company then
outstanding and would be able to effect the Merger pursuant to the "short-form"
merger provisions of the DGCL.

   Conditions to the Merger. The Merger Agreement provides that the obligations
of Parent, the Purchaser and the Company to consummate the Merger are subject
to the satisfaction of certain conditions, including the following: (a) the
Purchaser shall have purchased all Shares duly tendered and not withdrawn
pursuant to the terms of the Offer and subject to the terms thereof; provided
that the obligation of the Parent and the Purchaser to effect the Merger shall
not be conditioned on the fulfillment of such condition if the failure of the
Purchaser to purchase the Shares pursuant to the Offer shall have constituted a
breach of the Offer or of the Merger Agreement; (b) the consummation of the
Merger shall not be precluded by any order, decree or injunction of a court of
competent jurisdiction (each party having agreed to use its best efforts to
have any such order reversed or injunction lifted), and there shall not have
been any action taken or any law enacted, promulgated or deemed applicable to
the Merger by any court, arbitral tribunal, administrative agency or commission
or other governmental or regulatory authority, foreign or domestic (each, a
"Governmental Entity") that makes consummation of the Merger illegal; (c) if
required by the Certificate of Incorporation and By-Laws of the Company and the
DGCL, the Merger Agreement shall have been approved and adopted by the
affirmative vote of the holders of the requisite number of Shares in accordance
with the Certificate of Incorporation and By-Laws of the Company and the DGCL;
and (d) any applicable waiting period under the HSR Act shall have expired or
been terminated and, if applicable, the Director of Investigation and Research
appointed under the Competition Act (Canada) shall not have advised the
Purchaser, in writing, that he intends to oppose the acquisition of the Shares
or that he has taken or threatened to take proceedings under the Competition
Act (Canada) in respect of the purchase of Shares.

   Termination of the Merger Agreement. The Merger Agreement may be terminated
at any time prior to the effective time of the Merger, whether prior to or
after approval of the terms of the Merger Agreement by the stockholders of the
Company:

     (1) by the mutual written consent of Parent, the Purchaser and the
  Company duly authorized by their respective Boards of Directors;

                                       4
<PAGE>

     (2) by either the Parent or the Company if, on or before December 6,
  1999, the Purchaser shall not have purchased in the Offer such number of
  Shares which represent in excess of 50% of the outstanding Shares on a
  fully diluted basis, or the Merger shall not have been consummated on or
  before March 5, 1999, provided, however, that the right to terminate the
  Merger Agreement is not available to any party whose failure to fulfill any
  obligation under the Merger Agreement has been the cause of, or resulted
  in, the failure of the Offer or the Merger to have occurred on or before
  the aforesaid date;

     (3) by either the Parent or the Company if the Offer shall expire or
  terminate in accordance with its terms without any Shares having been
  purchased thereunder and, in the case of termination by the Parent, the
  Purchaser shall not have been required by the terms of the Offer or the
  Merger Agreement to purchase any Shares pursuant to the Offer;

     (4) by the Company if the Purchaser shall not timely commence the Offer
  as provided in the Merger Agreement;

     (5) unilaterally by the Purchaser and Parent on the one hand (treated as
  a single party) or the Company on the other hand (i) if the other fails to
  perform any material covenant in any material respect in the Merger
  Agreement, and does not cure the failure in all material respects within 30
  business days after the terminating party delivers written notice of the
  alleged failure or (ii) if any condition to the obligations of that party
  is not satisfied (other than by reason of a breach by that party of its
  obligations hereunder), and it reasonably appears that the condition cannot
  be satisfied prior to March 5, 1999;

     (6) by either the Purchaser or the Company if either is prohibited by an
  order or injunction (other than an order or injunction on a temporary or
  preliminary basis) of a court of competent jurisdiction or other
  Governmental Entity from consummating the Offer or the Merger and all means
  of appeal and all appeals from such order or injunction have been finally
  exhausted;

     (7) by the Purchaser if the Board of Directors of the Company shall have
  withdrawn or modified, or resolved to withdraw or modify, in any manner
  which is adverse to Parent or the Purchaser, its recommendation or approval
  of the Offer, the Merger or the Merger Agreement; or

     (8) by the Company if (i) the Board of Directors of the Company shall
  have determined in good faith, after consultation with outside counsel,
  that it is necessary, in order to comply with its fiduciary duties to the
  Company's stockholders under applicable law, to terminate the Merger
  Agreement to enter into an agreement with respect to or to consummate a
  transaction constituting a Superior Proposal (as defined under "Takeover
  Proposals"), (ii) the Company shall have given notice to the Purchaser
  advising the Purchaser that the Company has received a Superior Proposal
  from a third party, specifying the material terms and conditions (including
  the identity of the third party) and that the Company intends to terminate
  the Merger Agreement, (iii) either (A) the Purchaser shall not have revised
  its proposal for an Acquisition Transaction within two (2) business days
  from the time on which such notice is deemed to have been given to Parent,
  or (B) if the Purchaser within such period shall have revised its proposal
  for an Acquisition Transaction, the Board of Directors of the Company,
  after receiving advice from the Company's financial advisor, shall have
  determined in its good faith reasonable judgment that the third party's
  proposal for an Acquisition Transaction is more favorable from a financial
  point of view than Parent's revised proposal for an Acquisition Transaction
  and (iv) the Company, at the time of such termination, pays the Parent
  Expenses and the Termination Fee (each as defined under "Fees and Expenses"
  below).

   Takeover Proposals. The Merger Agreement provides that the Company shall
not, shall not permit any of its subsidiaries to, and shall not authorize or
permit any officer, director or employee or any investment banker, attorney,
accountant or other advisor or representative of the Company or any of its
subsidiaries to, directly or indirectly, except as otherwise described in this
Section (i) initiate, solicit, negotiate, encourage, or provide confidential
information to facilitate any proposal or offer to acquire all or any
substantial part of the business and properties of the Company and its
subsidiaries, taken as a whole, or beneficial ownership (as determined pursuant
to Rule 13d-3 promulgated under the Exchange Act) of 20% or more of the capital
stock of the

                                       5
<PAGE>

Company, whether by merger, purchase of assets, tender offer or otherwise,
whether for cash, securities or any other consideration or combination thereof
(such transactions being referred to herein as "Acquisition Transactions"),
(ii) enter into any agreement with respect to any Acquisition Transaction or
give any approval of the type referred to in the next paragraph below with
respect to any Acquisition Transaction or (iii) participate in any discussions
regarding, or take any other action to facilitate any inquiries or the making
of any proposal that constitutes or may reasonably be expected to lead to any
Acquisition Transaction. Notwithstanding the immediately preceding sentence,
the Company and its subsidiaries may, prior to the approval of the Merger
Agreement by the Company's stockholders, in response to any unsolicited
proposal for an Acquisition Transaction, furnish information concerning its
business, properties or assets to the corporation, partnership, person or other
entity or group (a "Potential Acquiror") making such proposal for an
Acquisition Transaction and participate in negotiations with the Potential
Acquiror if (x) the Company's Board of Directors after consultation with one or
more of its independent financial advisors, is of the reasonable belief that
such Potential Acquiror has the financial wherewithal to consummate such an
Acquisition Transaction, (y) the Company's Board of Directors reasonably
determines, after receiving advice from the Company's financial advisor, that
such Potential Acquiror has submitted a proposal for an Acquisition Transaction
that involves consideration to the Company's stockholders and other terms that
taken as a whole are more favorable from a financial point of view than the
Merger and (z) the Company's Board of Directors determines in good faith, after
consultation with outside counsel, that it is necessary to so furnish
information and negotiate in order to comply with its fiduciary duty to
stockholders of the Company. The Merger Agreement provides that in the event
the Company shall determine to provide any information as described above, or
shall receive any offer of the type referred to in this section or shall
receive or become aware of any other proposal to acquire a substantial part of
the business and properties of the Company and its subsidiaries, taken as a
whole, or to acquire a substantial amount of capital stock of the Company, it
shall promptly inform Parent orally as to the fact that information is to be
provided and shall furnish to Parent the identity of the recipient of such
information and/or the proponent of such offer or proposal and a description of
the material terms thereof. The Company is also obligated to keep Parent fully
informed of the status and material details of any proposed Acquisition
Transaction or other transaction (including any material amendments or material
proposed amendments of any such proposed Acquisition Transaction or other
transaction).

   The Merger Agreement also provides that neither the Board of Directors of
the Company nor any committee thereof (x) shall withdraw or modify or propose
to withdraw or modify, in any manner adverse to Parent, the approval or
recommendation of such Board of Directors or such committee of the Merger
Agreement, the Offer or the Merger or (y) approve or recommend, or propose to
approve or recommend, any proposal for an Acquisition Transaction except, in
each case, in connection with a Superior Proposal. As used herein, the term
"Superior Proposal" means a bona fide proposal to acquire, directly or
indirectly, for consideration consisting of cash and/or securities, more than
50% of the Shares then outstanding or all or substantially all the assets of
the Company, provided (i) such proposed transaction satisfies the tests set
forth in clauses (x), (y) and (z) of the second sentence of the immediately
preceding paragraph and (ii) the Board of Directors determines, in its good
faith reasonable judgment, that such proposed transaction is reasonably likely
to be consummated without undue delay.

   The Merger Agreement also provides that nothing contained in the preceding
two paragraphs shall prohibit the Company from at any time taking and
disclosing to its stockholders a position contemplated by Rule 14e-2(a)
promulgated under the Exchange Act, provided that neither the Company nor its
Board of Directors shall, except as permitted by the preceding two paragraphs,
approve or recommend acceptance of a proposal for an Acquisition Transaction.

   Fees and Expenses. The Merger Agreement provides that the Company will pay,
or cause to be paid, in same day funds to Parent the sum of (x) Parent Expenses
(as defined below) and (y) $2,400,000 (the "Termination Fee") upon demand if
(i) the Company terminates the Merger Agreement in accordance with the
provision described in paragraph (8) under "Termination of Merger Agreement",
(ii) the Purchaser terminates the Merger Agreement in accordance with the
provisions described in paragraphs (5) or (7) under "Termination of Merger
Agreement" at any time after a proposal for an Acquisition Transaction has been
made or, (iii) the

<PAGE>

Company or the Purchaser terminates the Merger Agreement in accordance with the
provisions described in paragraphs (2) or (3) under "Termination of Merger
Agreement" at any time after a proposal for an Acquisition Transaction has been
made, and, within twelve (12) months after any termination referred to in the
immediately preceding clauses (ii) or (iii) of this sentence, any person that
made a proposal for an Acquisition Transaction (or an affiliate thereof)
completes a merger, consolidation or other business combination with the
Company or a subsidiary of the Company, or the purchase from the Company or
from a subsidiary of the Company of 20% or more (in voting power) of the voting
securities of the Company or of 20% or more (in market value) of the assets of
the Company and its subsidiaries, on a consolidated basis; provided that the
Company will not have any such obligations if the Purchaser terminates the
Merger Agreement in accordance with the provision described in paragraph
(5)(ii) under "Termination of Merger Agreement" as a result of the failure of a
condition to be satisfied unless the reason for the failure of such condition
to be satisfied is reasonably related to the making of such proposal for an
Acquisition Transaction. "Parent Expenses" shall mean reasonable and reasonably
documented out-of-pocket fees and expenses incurred or paid by or on behalf of
Parent in connection with the Offer and the Merger or the consummation of any
of the transactions contemplated by the Merger Agreement (including, without
limitation, fees and expenses of counsel, commercial banks, investment banking
firms, accountants, experts and consultants to Parent and any of its
affiliates); provided, however, that in no event shall Parent Expenses exceed
$400,000.

   The Merger Agreement also provides that Parent will pay, or cause to be
paid, in same day funds to the Company the Company Expenses (as defined below)
upon demand if Parent or the Purchaser terminates the Merger Agreement in
accordance with the provision described in paragraph (5) under "Termination of
Merger Agreement". Company Expenses shall mean reasonable and reasonably
documented out-of-pocket fees and expenses incurred or paid by or on behalf of
the Company in connection with the Offer and the Merger or the consummation of
any of the transactions contemplated by the Merger Agreement (including,
without limitation, fees and expenses of counsel, commercial banks, investment
banking firms, accountants, experts and consultants to the Company and any of
its affiliates); provided, however, that in no event shall Company Expenses
exceed $400,000.

   Conduct of Business by the Company. The Merger Agreement provides that,
except as otherwise expressly contemplated by the Merger Agreement (including
exceptions on the disclosure schedule thereto), as specifically disclosed in
certain documents filed by the Company with the SEC or to the extent that the
Purchaser shall otherwise consent in writing, during the period from the date
of the Merger Agreement to the effective time of the Merger the Company shall
not and shall cause its subsidiaries not to: (a) declare, set aside, make or

   The Merger Agreement further provides that on and after the date of the
Merger Agreement until the effective time of the Merger, except as expressly
required by the Merger Agreement (including exceptions on the disclosure
schedule thereto) or as otherwise expressly consented to by the Purchaser in
writing, the Company will, and will cause each of its subsidiaries to: (a)
carry on the business in the ordinary course of business in substantially the
same manner as heretofore conducted, and use commercially reasonable efforts to
(1) preserve intact its present business organization, (2) keep available the
services of its present officers and employees and (3) preserve intact its
relationships with customers, suppliers and others having business dealings
with it; (b) promptly advise the Purchaser in writing of any event, occurrence,

(c); and (e) conduct all tax affairs relating to it only in the ordinary course

would have been conducted if the Merger Agreement had not been entered into.

   Board of Directors. The Merger Agreement provides that promptly upon the
purchase by the Purchaser of more than 50% of the outstanding Shares on a
fully-diluted basis pursuant to the Offer and from time to time thereafter, the
Company shall use its best efforts to allow the Purchaser to designate up to
the minimum number

                                       8
<PAGE>

of directors of the Company necessary in order for the result (expressed as a
fraction) derived by dividing the number of directors so designated by the
total number of directors to be at least equal to the result (expressed as a
fraction) derived by dividing the number of Shares then held by the Purchaser
by the total number of Shares then outstanding, provided, however, that until
the consummation of the Merger, the Board of Directors of the Company will have
at least two (2) Independent Directors. Subject to applicable law, the Company
has agreed to use its best efforts to effect any such election, including
mailing to its stockholders the Information Statement containing the
information required by Section 14(f) of the Exchange Act and Rule 14f-1
promulgated thereunder, which Information Statement is attached as Schedule I
to the Schedule 14D-9. The term "Independent Director" means a director who is
neither designated by the Purchaser nor otherwise affiliated with the Parent or
the Purchaser and is not an employee of the Company or any of its subsidiaries.

   Stock Options. Pursuant to the Merger Agreement, immediately prior to the
effective time of the Merger, each then outstanding Stock Option, shall be
canceled by the Company in exchange for a payment in cash by the Purchaser (the
"Option Consideration") equal to the product of (i) the number of Shares
previously subject to the Stock Option and (ii) the excess, if any, of the
Offer Price over the aggregate exercise price for such Shares under such Stock
Option. As of the effective time of the Merger, each holder of a Stock Option
will be entitled to receive only an amount equal to the Option Consideration.
All Stock Option amounts payable shall be subject to any required withholding
of taxes and shall be paid without interest. Pursuant to the Merger Agreement,
the Company shall thereafter cause each stock option or other equity based plan
maintained with respect to any Shares (or rights in respect thereof) to be
terminated.

   Indemnification and Insurance. In the Merger Agreement, Parent and the
Purchaser have agreed for a period of six years after the effective time of the
Merger, the Surviving Corporation shall indemnify, defend and hold harmless the
present and former officers, directors, employees and agents of the Company and
its subsidiaries in such capacities against all losses, claims, damages,
expenses or liabilities arising out of actions or omissions or alleged actions
or omissions occurring at or prior to the effective time of the Merger to the
same extent and on the same terms and conditions (including with respect to
advancement of expenses) provided for in the Company's organizational documents
in effect at the date of the Merger Agreement (to the extent consistent with
applicable Law). For a period of six years after the effective time of the
Merger, the Surviving Corporation shall maintain in effect directors' and
officers' liability insurance covering the persons who are currently covered by
the Company's existing directors' and officers' liability insurance with
respect to claims arising from facts or events which occurred before the
effective time of the Merger, on terms and conditions no less favorable to such
directors and officers than those in effect on the date of the Merger
Agreement; provided that in no event shall the Surviving Corporation be
required to make annual premium payments for such insurance in excess of 150%
of the annual premiums payable by the Company for such insurance as of the date
of the Merger Agreement.

   Reasonable Efforts. The Merger Agreement provides that, except as otherwise
contemplated therein, Parent, the Purchaser and the Company each shall use
their commercially reasonable efforts to take promptly, or cause to be taken,
all actions and to do promptly, or cause to be done, all things necessary,
proper or advisable to consummate and make effective the transactions
contemplated by the Merger Agreement, including using their commercially
reasonable efforts (i) to obtain all necessary waivers, consents and approvals,
and (ii) to effect all necessary registrations and filings including, but not
limited to, the Offer Documents, Schedule 14D-9, Proxy Statement and any
required filing under the Competition Laws. In case at any time after the
effective time of the Merger any further action is necessary or desirable to
carry out the obligations of the parties under the Merger Agreement, the proper
officers and/or directors of Parent, the Purchaser and the Company, as the case
may be, shall take the necessary action.

   Representations and Warranties. The Merger Agreement contains various
customary representations and warranties.

RIGHTS OF STOCKHOLDERS IN THE MERGER

   No appraisal rights are available by virtue of the Offer. If the Merger is
consummated, however, stockholders of the Company who have not sold their
Shares will have certain rights under the DGCL to dissent and demand appraisal
of, and to receive payment in cash of the fair value of, their Shares.
Stockholders who perfect such rights by complying with the procedures set forth
in Section 262 of the DGCL ("Section 262") will have the fair value of their
Shares (exclusive of any element of value arising from the accomplishment or
expectation of the Merger) determined by the Delaware Court of Chancery and
will be entitled to receive a cash payment equal to such fair value from the
Surviving Corporation. In addition, such dissenting stockholders would be
entitled to receive payment of a fair rate of interest from the date of
consummation of the Merger on the amount determined to be the fair value of
their Shares. In determining the fair value of the Shares, the court is
required to take into account all relevant factors. Accordingly, such
determination could be based upon considerations other than, or in addition to,
the market value of the Shares, including, among other things, asset values and
earning capacity. In Weinberger v. UOP, Inc., the Delaware Supreme Court stated
that "proof of value by any techniques or methods which are generally
considered acceptable in the financial community and otherwise admissible in
court" should be considered in an appraisal proceeding. The Weinberger court
also noted that under Section 262, fair value is to be determined "exclusive of
any element of value arising from the accomplishment or expectation of the
merger." In Cede & Co. v. Technicolor, Inc., however, the Delaware Supreme
Court stated that, in the context of a two-step cash merger, "to the extent
that value has been added following a change in majority control before cash-
out, it is still value attributable to the going concern," to be included in
the appraisal process. As a consequence of the foregoing, the fair value
determined in any appraisal proceeding could be the same as or more or less
than the Merger Consideration.

   Purchaser does not intend to object, assuming the proper procedures are
followed, to the exercise of appraisal rights by any stockholder and the demand
for appraisal of, and payment in cash for the fair value of, the Shares.

   THE FOREGOING SUMMARY OF THE RIGHTS OF DISSENTING STOCKHOLDERS DOES NOT
PURPORT TO BE A COMPLETE STATEMENT OF THE PROCEDURES TO BE FOLLOWED BY
STOCKHOLDERS DESIRING TO EXERCISE ANY AVAILABLE APPRAISAL RIGHTS AND IS
QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF SECTION 262. THE
PRESERVATION AND EXERCISE OF APPRAISAL RIGHTS ARE CONDITIONED ON STRICT
ADHERENCE TO THE APPLICABLE PROVISIONS OF THE DGCL.

ITEM 4. THE SOLICITATION OR RECOMMENDATION

   (a) Recommendation of the Board of Directors

   The Board of Directors of the Company (the "Board") has unanimously
determined that each of the Merger Agreement, the Offer and the Merger are
advisable and fair to, and in the best interests of, the stockholders of the
Company and unanimously recommends that stockholders of the Company accept the
Offer and tender their Shares to Purchaser thereunder.

   As set forth in the Merger Agreement, the Purchaser will purchase Shares
tendered prior to the close of the Offer if the conditions to the Offer have
been satisfied (or waived).

   STOCKHOLDERS CONSIDERING NOT TENDERING THEIR SHARES IN ORDER TO WAIT FOR THE
MERGER SHOULD NOTE THAT IF THE MINIMUM CONDITION IS NOT SATISFIED OR ANY OF THE
OTHER CONDITIONS TO THE OFFER ARE NOT SATISFIED, THE PURCHASER IS NOT OBLIGATED
TO PURCHASE ANY SHARES AND, SUBJECT TO CERTAIN LIMITATIONS, CAN TERMINATE THE
OFFER AND THE MERGER AGREEMENT AND NOT PROCEED WITH THE MERGER.

   Under Delaware Law, the approval of the Board and the affirmative vote of
the holders of a majority of the outstanding Shares are generally required to
approve the Merger. Accordingly, if Purchaser acquires a majority of the
outstanding Shares in the Merger, the Purchaser will have sufficient voting
power to cause the approval of the Merger without the affirmative vote of any
other stockholder. Under Delaware law, if Purchaser

                                       10
<PAGE>

acquires, pursuant to the Offer or otherwise, at least 90% of the then
outstanding Shares, Purchaser will be able to approve and adopt the Merger
Agreement and the Merger without a vote of the Company's stockholders. Parent,
Purchaser, and the Company have agreed to use their commercially reasonable
best efforts to take, or to cause to be taken, all actions and to do, or to
cause to be done all things necessary, proper or advisable under applicable
laws to consummate the Offer, the Merger and the other transactions
contemplated by the Merger Agreement. If Purchaser does not acquire at least
90% of the then outstanding Shares pursuant to the Offer or otherwise and a
vote of the Company's stockholders is required under Delaware Law, a longer
period of time will be required to effect the Merger.

   The Offer is scheduled to expire at 12:00 midnight, New York City time, on
Tuesday, October 12, 1999, unless the Offer is extended pursuant to the Merger
Agreement. A copy of the press release issued by the Parent and the Company
dated September 8, 1999 announcing the Merger and the Offer is filed as Exhibit
(6) to this Schedule 14D-9 and is incorporated herein by reference in its
entirety.

BACKGROUND OF THE OFFER; REASONS FOR THE RECOMMENDATION

 Background of the Offer.

   On June 8, 1998, at a telecommunications industry trade show in Atlanta,
Georgia, representatives of both the Company and Dynatech informally met to
discuss the possibility of a business combination between the two companies. No
further discussions ensued at that time.

   On January 14, 1999, Mr. Donald Strohmeyer, a retired telecommunications
industry executive, was retained by the Company as a consultant to perform a
comprehensive business analysis of the Company.

   On February 7, 1999, at a meeting of the outside directors, Mr. Strohmeyer
presented his findings to the Board. At this meeting, Mr. Strohmeyer presented
his analysis of the Company's long-term prospects, including his analysis of
the concentration of customer base, employee retention and technology migration
and the Company's financial performance, and recommended that the Company seek
a combination with a larger company.

   On February 20, 1999, at a meeting of the Board of Directors, the Board
appointed Mr. Strohmeyer the position of President and Chief Executive Officer
of the Company, effective February 22, 1999.

   On March 12, 1999, at a meeting of the Board, the Board discussed various
potential strategic partners and discussed the viability of selling certain of
the Company's technology and related assets in a business combination.

   In late March 1999, Mr. Samuel Tishler, Corporate Vice President--Corporate
Development of Dynatech, contacted Mr. Strohmeyer by telephone to request a
meeting to discuss a potential business combination with the Company.

   In April 1999, another potential strategic partner contacted Mr. Strohmeyer
regarding an interest in a partnership or other business combination. Mr.
Strohmeyer and a representative of the potential strategic partner agreed to
meet at a later time.

   On April 13, 1999, a meeting was held in San Diego, California between Mr.
Tishler and other representatives of Dynatech, and Messrs. Strohmeyer and James
Keefe, Chief Financial Officer of the Company. The parties signed a standard
confidentiality and nondisclosure agreement, and initial company information
was exchanged.

   During the week of April 19, 1999, a meeting was held in San Diego between
the other potential strategic partner and the Company. The parties executed a
standard confidentiality and nondisclosure agreement, and exchanged company
information.

                                       11
<PAGE>

   On May 12, 1999, at a regularly scheduled Board meeting, the Board discussed
possible strategic opportunities. The Board directed management to interview an
investment banking firm.

   On May 13, 1999, the Company engaged Alliant Partners to represent the
Company in rendering financial advisory services in connection with the
possible sale or merger of the Company.

   On May 14, 1999, Gray Cary Ware & Freidenrich ("Gray Cary"), the Company's
outside legal counsel, delivered a memorandum to the Board that described the
Board's fiduciary obligations in considering a proposal for a business
combination.

   On May 24, 1999, at a special meeting of the Board, management discussed the
status of the Company's strategic opportunities. The Board discussed that
Alliant Partners or the Company had contacted more than 25 possible strategic
partners regarding a possible business combination and that Alliant Partners or
the Company had discussions with more than ten of these possible strategic
partners. Management then reviewed the status of the discussions with the
possible strategic partners.

   On May 25, 1999, Mr. Tishler and Mr. John Peeler, President and Chief
Executive Officer of Dynatech's telecommunications test business met with
Messrs. Strohmeyer, Keefe and O'Conner and continued their due diligence
exchanges.

   On June 21, 1999, members of the Board and management further discussed the
status of the Company's discussions with potential strategic partners.

   On June 24, 1999, Dynatech conveyed a preliminary offer of $70 million to
management.

   On June 28, 1999, at a special meeting of the Board, management reported on
the status of preliminary negotiations with Dynatech. Mr. Thomas Bentley of
Alliant Partners presented information regarding comparable companies,
comparable transactions, takeover multiples and the Company's historical stock
trading information. The Board engaged in a lengthy discussion regarding
possible alternative transactions and the fairness of a price tentatively
proposed by Dynatech. Based on the discussions, the Board directed management
to continue negotiations with Dynatech to increase the offer price.

   On June 29, 1999, Mr. Strohmeyer communicated to Mr. Tishler and Mr.
Mayerick, President of the Systems and Software Group of Dynatech's
telecommunications test business, that the $70 million offer was too low and
would have to be raised if further discussions were to be held. Mr. Tishler, on
behalf of Dynatech, then proposed a revised preliminary offer of $80 million.
Representatives of Dynatech prepared an outline of proposed due diligence
procedures and issues and a request that due diligence would need to take place
at certain of the Company's facilities as well as the offices of Gray Cary, the
Company's outside legal counsel, commencing July 13, 1999.

   In early July 1999, a second meeting was held in San Diego between
representatives of the Company and the other potential strategic partner.

   During the last two weeks of July 1999, intensive operational due diligence
was conducted by representatives of Dynatech at the Company's offices and the
offices of Gray Cary.

   On July 21, 1999, at a regularly scheduled meeting of the Board, after an
update by management of the Company's business and prospects, management
updated the Board regarding its discussions with Dynatech. Mr. Bentley again
reviewed the offer and comparable transactions. After a lengthy discussion
regarding the benefits to the stockholders of the Company of a possible
transaction with Dynatech, the timing of a possible transaction, other
alternatives, including a possible transaction with a different entity and
remaining a stand-alone entity, the Board determined to reconvene on July 26,
1999 for further discussions. The Board determined that it was not in the best
interests of the Company's stockholders to enter into a non-solicitation
agreement that had been requested by Dynatech and that would prevent the
Company from pursuing alternatives.

                                       12
<PAGE>

   On July 26, 1999, the Board reconvened its meeting and continued its
discussions regarding a possible acquisition by Dynatech. Management reviewed
the current status of its discussions with each potential strategic partner.
Mr. Bentley discussed the potential value to the stockholders of the Company
of a transaction with Dynatech and possible alternative transactions. After
lengthy discussions, the Board directed management to continue to move forward
with due diligence, and to continue to negotiate more favorable terms with
Dynatech while continuing to pursue alternatives.

   During the week of August 2, 1999, Mr. Mayerick met with each of Messrs.
Strohmeyer and Terry Allen, General Manager--Software, Kevin Pope, Vice
President--Engineering, and Donald O'Connor specifically to discuss the
possible terms of employment if a transaction were to be consummated.

   On August 5, 1999, a representative of the other potential strategic
partner called Mr. Strohmeyer and stated that the party had concluded that it
was not in a position to effect a business combination with the Company, but
it would consider a joint marketing and sales relationship with the Company.

   On August 11, 1999, Mr. Strohmeyer and Mr. O'Connor received a proprietary
e-mail from a representative of the other potential strategic partner
proposing a process of joint marketing between the party and the Company.
Negotiations were begun to select accounts and develop joint strategies
between the two companies.

   On August 11, 1999, Mr. Strohmeyer and Mr. Bentley called Mr. Tishler and
requested that Mr. Tishler deliver a letter summarizing the terms of
Dynatech's non-binding offer for consideration by the Company's Board.

   On August 13, 1999, Gray Cary recirculated to each member of the Board a
copy of the memorandum regarding director's fiduciary obligations in
considering a proposal for a business combination. On that same day, Mr.
Tishler delivered a letter to Mr. Strohmeyer in which he confirmed a non-
binding price of $80 million for all of the outstanding stock of the Company,
which offer was subject to the Company having net cash assets of at least
$14.2 million at closing, the cancellation of all outstanding options of the
Company, the satisfactory completion of Dynatech's due diligence, approval of
Dynatech's Board, and the negotiation and execution of a definitive merger
agreement satisfactory to Dynatech.

   During the weeks of August 10 and August 16, due diligence continued at the
offices of Gray Cary.

   On August 18, 1999, Mr. Bentley and Mr. Tishler met to further negotiate
the business terms of the potential acquisition.

   On August 19, 1999 and August 26, 1999, the Board met to review the current
status of negotiations with Dynatech and possible alternative strategic
partners.

   On August 26, 1999, Dynatech's legal counsel sent an initial draft of the
proposed Merger Agreement to Gray Cary.

   On August 31, 1999, Gray Cary sent comments on the Merger Agreement to
legal counsel for Dynatech. The Company, Dynatech and their respective counsel
negotiated the Merger Agreement throughout the week of August 30, 1999.

   On September 2, 1999, the Board met to review the status of the
negotiations and the Merger Agreement.

   On September 4, 1999, each director received a copy of the Merger
Agreement, a summary of the Offer terms and a copy of the memorandum regarding
the Board's fiduciary obligations in considering a proposal for a business
combination.

                                      13
<PAGE>

   On September 7, 1999, the Board held a special meeting. At the meeting, Gray
Cary made a detailed presentation regarding the Board's fiduciary duties when
considering the sale of the Company and then reported on the negotiations and
the terms and conditions of the Merger Agreement. A representative of Alliant
Partners then made a detailed presentation regarding the proposed transaction
and presented the opinion that, as of the date thereof, the consideration to be
received by the Company's stockholders in the Offer and the Merger, at $5.37
per share, was fair from a financial point of view. Following discussion of the
Offer and the Merger, the Board unanimously approved the Offer and the Merger
and unanimously resolved to recommend that the stockholders of the Company
accept the Offer and tender their shares in the Offer and that the stockholders
approve and adopt the Merger Agreement. During the remainder of the day, the
final terms of the Merger Agreement were negotiated to the mutual satisfaction
of the parties. After the end of business day on September 7, 1999, the Merger
Agreement was signed and delivered by the respective parties.

   On September 8, 1999, prior to the opening of stock trading, Dynatech and
the Company issued a press release announcing the execution of the Merger
Agreement.

   Reasons for the Recommendation. In reaching its determination described in
paragraph (a) above, the Board considered a number of factors, including, but
not limited to the following:

     (i) the need to attract and retain employees in a highly competitive
  marketplace competing against better funded and start-up companies;

     (ii) historical information concerning the Company's business prospects,
  financial performance and condition, operations, technology, management and
  competitive position;

     (iii) the business and strategic objectives of the Company as well as
  the risks involved in achieving those objectives;

     (iv) the Company's dependency on a few large customers without long-term
  contractual commitments;

     (v) the performance of the Company on a historical basis and the
  prospects and risks of the Company going forward as an independent company;

     (vi) the consideration to be received by the Company stockholders in the
  Merger and a comparison of merger transactions deemed to be comparable to
  the Merger;

     (vii) the terms of the Merger Agreement, including the parties'
  representations, warranties and covenants, and the conditions to their
  respective obligations;

     (viii) the potential for other third parties with sufficient resources
  and complementary technology to acquire the Company;

     (ix) a review of the possible alternatives to the Offer and the Merger
  (including the possibility of continuing to operate the Company as an
  independent entity), the range of possible benefits and risks to the
  Company's stockholders of such alternative and the timing and the
  likelihood of actually accomplishing any of such alternatives;

     (x) the presentation to the Board by Alliant Partners at the September
  7, 1999 Board meeting;

     (xi) the written opinion of Alliant Partners to the effect that, as of
  September 7, 1999, the $5.37 in cash to be received by holders of Shares in
  the Offer and the Merger is fair to such holders from a financial point of
  view. The full text of this written opinion, which sets forth assumptions
  made, matters considered and limitations on the review undertaken in
  connection with the opinion, is attached as Annex B. STOCKHOLDERS ARE URGED
  TO, AND SHOULD, READ THIS OPINION IN ITS ENTIRETY;

     (xii) the fact that pursuant to the Merger Agreement, the Company is not
  prohibited from responding to any unsolicited Superior Proposal as defined
  in the Merger Agreement to acquire the Company, and the Company may
  terminate the Merger Agreement and accept any such Superior Proposal
  subject to the Company's obligation to pay the Termination Fee and Expenses
  as defined in the Merger Agreement;

                                       14
<PAGE>

     (xiii) current financial market conditions and historical market prices,
  volatility and trading information with respect to the Common Stock of the
  Company;

     (xiv) the relationship of the Offer price to historical market prices of
  the Company's Common Stock and to the Company's book value and liquidation
  value per share, and the fact that the Offer price of $5.37 represented a
  premium of approximately 22% over the average of the last sale prices of
  the Company's Common Stock over the last thirty trading days ending
  September 3, 1999 (the last trading day before the announcement of the
  Merger Agreement), which was $4.39 and a premium of approximately 67% over
  the average of the last sale prices of the Company's Common Stock on the
  trading days during the 12 month period ending September 3, 1999, which is
  $3.22;

     (xv) the likelihood that the proposed acquisition would be consummated,
  including the experience, reputation and financial condition of Parent and
  the risks to the Company if the acquisition were not consummated, including
  (a) the Company's sales and operating results, (b) progress of certain
  development projects and products, and (c) the Company's stock price; and

     (xvi) the availability of appraisal rights in the Merger under
  applicable law.

In view of the wide variety of factors considered in connection with its
evaluation of the Offer and the Merger, the Board did not find it practicable,
and did not quantify or otherwise attempt to assign relative weights to the
factors it considered.

   THE FULL TEXT OF THE WRITTEN FAIRNESS OPINION OF ALLIANT PARTNERS IS FILED
AS EXHIBIT (5) TO THIS SCHEDULE 14D-9 AND IS ALSO ATTACHED HERETO AS ANNEX B.
STOCKHOLDERS ARE URGED TO, AND SHOULD, READ SUCH OPINION IN ITS ENTIRETY. SUCH
OPINION WAS PRESENTED FOR THE INFORMATION OF THE BOARD IN CONNECTION WITH THEIR
CONSIDERATION OF THE MERGER AGREEMENT AND IS DIRECTED ONLY TO THE FAIRNESS FROM
A FINANCIAL POINT OF VIEW OF THE CONSIDERATION TO BE RECEIVED BY THE HOLDERS OF
THE SHARES (OTHER THAN PARENT) PURSUANT TO THE OFFER AND THE MERGER. SUCH
OPINION DOES NOT CONSTITUTE A RECOMMENDATION TO ANY STOCKHOLDER AS TO WHETHER
TO TENDER SHARES IN THE OFFER OR HOW TO VOTE WITH RESPECT TO THE MERGER.

   IN LIGHT OF ALL THE FACTORS SET FORTH ABOVE, THE BOARD DETERMINED THAT EACH
OF THE MERGER AGREEMENT, THE OFFER AND THE MERGER IS ADVISABLE AND FAIR TO, AND
IN THE BEST INTERESTS OF, THE STOCKHOLDERS OF THE COMPANY, AND RESOLVED
UNANIMOUSLY TO APPROVE THE MERGER AGREEMENT, THE OFFER AND THE MERGER, AND TO
RECOMMEND THAT STOCKHOLDERS OF THE COMPANY ACCEPT THE OFFER AND TENDER THEIR
SHARES IN THE OFFER.

ITEM 5. PERSONS RETAINED, EMPLOYED OR TO BE COMPENSATED

   Pursuant to a letter agreement dated May 13, 1999, as amended, between the
Company and Alliant Partners, the Company agreed to retain Alliant Partners to
provide certain financial advisory services to the Company, including
preparation of Alliant Partner's opinion that the Offer Price to be received by
holders of Shares pursuant to the Offer and the Merger Consideration pursuant
to the Merger is fair to the Company's stockholders from a financial point of
view. As compensation for Alliant Partner's services in connection with the
transactions contemplated by the Merger Agreement, the Company has agreed to
pay Alliant Partners fees of approximately $800,000 upon the closing of the
Merger. The Company has also agreed to reimburse Alliant Partners for its
reasonable out-of-pocket expenses incurred in connection with rendering
financial advisory services and to indemnify Alliant Partners and its
directors, officers, agents, employees and controlling persons for certain
costs, expenses and liabilities, including certain liabilities under the
federal securities laws.

   Except as set forth above, neither the Company nor any person acting on its
behalf has or currently intends to employ, retain or compensate any person to
make solicitations or recommendations to the stockholders of the Company on its
behalf with respect to the Offer, except that such solicitations or
recommendations may be made by directors, officers or employees of the Company,
for which services no additional compensation will be paid.

                        SECTION 14(f) OF THE SECURITIES
          EXCHANGE ACT OF 1934, AS AMENDED, AND RULE 14f-1 THEREUNDER

   This Information Statement is being mailed on or about September 14, 1999 as
a part of the Solicitation/Recommendation Statement on Schedule 14D-9 (the
"Schedule 14D-9") of Applied Digital Access, Inc. (the "Company") to the
holders of record of shares of Common Stock, par value $0.001 per share, of the
Company (the "Shares") at the close of business on or about September 14, 1999.
You are receiving this Information Statement in connection with the possible
appointment of persons designated by the Purchaser (as defined below) to a
majority of the seats on the Board of Directors of the Company (the "Board").

   On September 7, 1999, the Company, Dynatech Corporation, a Delaware
corporation ("Dynatech" or "Parent") and Dynatech Acquisition Corporation, a
Delaware corporation and an indirect wholly owned subsidiary of Parent (the
"Purchaser"), entered into an Agreement and Plan of Merger (the "Merger
Agreement") in accordance with the terms and subject to the conditions of which
(i) Parent will cause the Purchaser to commence a tender offer (the "Offer")
for all outstanding Shares at a price of $5.37 per Share, net to the seller in
cash and without interest thereon, and (ii) the Purchaser will be merged with
and into the Company (the "Merger"). As a result of the Offer and the Merger,
the Company will become an indirect wholly owned subsidiary of Parent.

   The Merger Agreement requires the Company to use its best efforts either to
increase the size of the Board or to secure the resignation of such number of
its incumbent directors, or both, as is necessary to enable certain directors
designated by Parent to be elected or appointed to the Board under the
circumstances described therein. See "Board of Directors and Executive Officers
of the Company."

   This Information Statement is required by Section 14(f) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), and Rule 14f-1
thereunder. You are urged to read this Information Statement carefully. You are
not, however, required to take any action at this time. Capitalized terms used
herein and not otherwise defined herein shall have the meaning set forth in the
Schedule 14D-9.

   Pursuant to the Merger Agreement, the Purchaser commenced the Offer on
Tuesday, September 14, 1999. The Offer is scheduled to expire at 12:00
Midnight, New York City time, on October 12, 1999, unless the Offer is extended
pursuant to the Merger Agreement.

General

   The Shares are the only class of voting securities of the Company
outstanding. Each Share has one vote. As of September 14, 1999, there were
13,251,830 Shares outstanding. The Company's Board of Directors currently
consists of seven (7) authorized members. At each annual meeting of the
Company's stockholders, directors are elected to serve until the next annual
meeting. The officers of the Company serve at the discretion of the Board.

Right To Designate Directors

   The Merger Agreement provides that promptly after (i) the purchase of and
payment for any Shares by Purchaser or any of its affiliates which represent at
least a majority of the then outstanding Shares and (ii) compliance with
Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder,
whichever occurs later, Dynatech shall be entitled to designate such number of
directors, rounded up to the next whole number, as will give Dynatech
representation on the Board equal to the product of the total number of
directors

                                      A-1
<PAGE>

on the Board (giving effect to any increase in the number of directors pursuant
to the Merger Agreement) multiplied by the percentage that such aggregate
number of Shares so purchased or otherwise beneficially owned by Purchaser
(including Shares tendered for payment) bears to the total number of
outstanding Shares. The Company shall, upon request by Dynatech, increase the
size of the Board, or secure the resignations of such number of directors, or
both, as is necessary to enable Dynatech's designees to be elected or appointed
to the Board and will cause Dynatech's designees to be so elected or appointed,
provided, however, that pursuant to the Merger Agreement, prior to the
effective time of the Merger, the Board shall have two independent directors
(as defined in Section 1.3(c) of the Merger Agreement).

   IN THE EVENT THAT DYNATECH AND ITS SUBSIDIARIES DO NOT ACQUIRE ANY SHARES
PURSUANT TO THE OFFER, OR TERMINATE THE OFFER, OR IF THE MERGER AGREEMENT IS
TERMINATED PURSUANT TO ITS TERMS PRIOR TO THE ELECTION OR APPOINTMENT OF
DYNATECH'S DESIGNEES, PURCHASER AND DYNATECH WILL NOT HAVE ANY RIGHT, UNDER THE
MERGER AGREEMENT TO HAVE DYNATECH'S DESIGNEES ELECTED OR APPOINTED TO THE
COMPANY'S BOARD OF DIRECTORS.

   The information contained in this Information Statement concerning Dynatech
and Dynatech's designees has been furnished to the Company by Dynatech, and the
Company assumes no responsibility for the accuracy or completeness of such
information.

The Dynatech Designees

acquire any securities) of the Company. The Company has been advised by

 (1) Potential gains are net of exercise price, but before taxes associated
     with exercise. These amounts represent certain assumed rates of
     appreciation only, in accordance with the SEC's rules. Actual gains, if
     any, on stock option exercises are dependent on the future performance of
     the Common Stock, overall market conditions and the option holders'
     continued employment through the vesting period. The amounts reflected in
     this table may not necessarily be achieved.

 (2) Options granted in fiscal 1998 under the Company's 1994 Stock Option/Stock
     Issuance Plan (the "1994 Option Plan") generally vest and become
     exercisable over a four year period at the rate of 1/48 per month for each
     full month of the optionee's continuous employment with the Company. Under
     the 1994 Option Plan, the Board retains discretion to modify the terms,
     including the price, of outstanding options. The shares subject to each
     option will immediately vest in the event the Company is acquired by a
     merger or asset sale unless the option is assumed by the successor entity.
     See "--Severance and Change of Control Arrangements."

 (3) Based upon options granted to purchase an aggregate of 2,990,941 shares of

 (4) All options listed were granted at market value on the date of grant,
     based on the closing selling price of the Company's Common Stock on such
     date.

 (5) On February 22, 1999, Mr. Savage was appointed to the position of Chairman
     of the Board of the Company and resigned from the positions of President
     and Chief Executive Officer.

 (6) On January 25, 1999, Mr. Murphy resigned from his position of Vice
     President, Sales and Marketing with the Company.

 (7) In September 1998 and November 1998, as a result of a broad decline in the
     fair market value of the Company's Common Stock, the Compensation
     Committee determined that it was in the best interests of the Company to
     offer to all current employees who were option holders, including
     executive officers, whom the Committee considered separately, the
     opportunity to have outstanding options with an exercise price above the
     then current market price cancelled in exchange for new options with an
     exercise price equal to the then current fair market value. For details
     concerning the cancellation and regrant of options,

SEVERANCE AND CHANGE OF CONTROL ARRANGEMENTS

   In November 1998, the Company entered into certain retention agreements
("agreements") with its chief executive officer and executive officers
("Executives") relating to a change in control of the Company. Under the
agreements, the termination of an Executive's employment without cause of for
"good reason", as defined in the agreement, within twelve months following a
change in control of the Company would be deemed a covered termination. A
covered termination provides for the continuation of an Executive's base salary
for a period of eighteen months for the chief executive officer and twelve
months for the executive officers. The Executive will be deemed a consultant of
the Company during these periods ("Consulting Periods"). The Executive's then
outstanding stock options will continue vesting and employee benefits will
continue to be provided by the Company during the Consulting Period.

   In February 1999, the Company entered into an employment arrangement with
Donald L. Strohmeyer, the Company's President and Chief Executive Officer. If
Mr. Strohmeyer is terminated without cause, the Company has agreed to pay him
his monthly base salary for a period of twelve months after his termination. In
addition, during such twelve month period, Mr. Strohmeyer will continue to vest
in any outstanding stock options still subject to vesting. The arrangement does
not have an expiration date and is operative during Mr. Strohmeyer's employment
by the Company.

   In November 1990, the Company entered into an employment arrangement with
Peter P. Savage, the Company's Chairman of the Board. If Mr. Savage is
terminated without cause, the Company has agreed to pay him his monthly base
salary for a period of six months after his termination or until he commences
employment with another company. In addition, he will be entitled to his pro
rata share of any guaranteed bonus or profit sharing plan in which he
participated (for the portion of the year that he was employed by the Company).
During the severance term, Mr. Savage would continue to be treated as a Company
employee for

                                      A-11
<PAGE>

purposes of all Company-provided employee benefits (other than for purposes of
stock option vesting and vacation eligibility). The arrangement does not have
an expiration date and is operative during Mr. Savage's employment by the
Company.

   In January 1999, the Company entered into a severance arrangement with
Steven F.X. Murphy, the Company's former Vice President, Sales and Marketing.
Under the severance arrangement, Mr. Murphy will receive his base salary for a
period of six months ending in June 1999.

   In June 1988, the Company entered into an employment arrangement with Paul
R. Hartmann, the Company's Vice President, Systems Engineering. If Mr. Hartmann
is terminated without cause, the Company has agreed to pay him his monthly base
salary for a period of six months after the termination or until he commences
employment with another company. The arrangement does not have an expiration
date and is operative during Mr. Hartmann's employment by the Company.

   In May 1995, the Company entered into an employment arrangement with Donald
J. O'Connor, the Company's Vice President, Customer Support. If Mr. O'Connor is
terminated involuntarily, the Company has agreed to pay him a severance payment
equal to three months of his monthly base salary upon such termination. The
arrangement does not have an expiration date and is operative during Mr.
O'Connor's employment by the Company.

   Pursuant to the 1994 Option Plan, in the event the Company is acquired,
whether by merger or asset sale, each outstanding option which is not to be
assumed by the successor corporation or replaced with a comparable option to
purchase the capital stock of the successor corporation will automatically
accelerate vesting in full, and all unvested shares will automatically vest,
except to the extent such accelerated vesting is precluded by the terms of the
agreements evidencing those unvested shares.

   The 1994 Option Plan also provides for the automatic acceleration of vesting
with respect to outstanding options or shares upon the following change in
control events: (i) the acquisition of more than 50% of the Company's voting
stock by hostile tender offer or (ii) a change in the composition of the Board
of Directors effected through one or more contested Board elections, except
that the Compensation Committee may at the time of a discretionary option grant
or stock issuance, provide that no such acceleration shall occur.

   As a result of the Company entering into the Merger Agreement, all stock
options outstanding under the 1994 Option Plan at the consummation of the
Merger, whether or not then exercisable, shall be canceled by the Company in
exchange for the right to receive the Option Consideration. See "The Merger
Agreement--Stock Options."

              REPORT OF THE COMPENSATION COMMITTEE OF THE BOARD OF
                      DIRECTORS ON EXECUTIVE COMPENSATION

   In fiscal 1998, the Compensation Committee of the Board of Directors was
comprised of Kenneth E. Olson and Christopher B. Paisley. The Compensation
Committee was responsible for setting and administering the policies governing
annual compensation of the executive officers of the Company. These policies
are based upon the philosophy that the Company's long term success in its
marketplace is best achieved through (i) recruitment and retention of the best
people in the industry and (ii) providing compensation that focuses executive
officer efforts on maximizing both short and long term financial performance of
the Company. The Compensation Committee applied this philosophy in determining
compensation for the Company's executive officers in four areas: salary, annual
incentive programs, long term incentive compensation and benefits.

   Each executive officer's aggregate compensation is designed to provide a
cumulative level of compensation roughly equivalent to the median paid by
comparably sized companies in similar industries and geographic locations. In
determining executive officers' compensation, the Compensation Committee
considers information contained in surveys such as the American Electronics
Association ("AEA") Executive Compensation Survey, the Radford Executive
Compensation survey, and various surveys published by venture capital firms. In
recent years, these surveys have experienced year to year increases of
approximately 5% each year.

   In 1998, there were no compensation adjustments for the executive officers.

Salary

   The Company attempts to offer salaries to its executive officers which are
generally targeted near the median for similar positions in comparably sized
companies in the Company's industry and geographic location. The Company's
Chief Executive Officer evaluates the performance of all other executive
officers, and recommends salary adjustments which are subject to review by the
Compensation Committee. In addition to considering the results of performance
evaluations and information concerning competitive salaries, the Compensation
Committee and the Chief Executive Officer place weight on the financial
condition of the Company and the competitive employment situation in the
Company's industry and geographic area in considering salary adjustments.

   The Company's Chief Executive Officer did not recommend any salary
adjustments for the Company's other executive officers in fiscal 1998.

Annual Incentive Compensation

   The Company seeks to provide additional incentives to executives who make
contributions of outstanding value to the Company. For this reason, the
Compensation Committee awards incentive compensation which can comprise a
substantial portion of the total compensation of executive officers when earned
and paid. Incentive compensation may be paid to executives pursuant to three
plans: the Management Team Incentive Compensation Plan, the Sales Management
Incentive Compensation Plan and the Gain Sharing Plan. The Compensation
Committee attempts to structure these plans so that if the maximum amount
available under these plans is earned by an executive officer, his total cash
compensation for the year will be slightly above the median paid to executive
officers in similar positions at comparably sized companies in similar
industries and geographic locations.

   Management Team Incentive Compensation Plan. Potential compensation paid
under this plan is set as a significant percent of each officer's base salary.
The total incentive compensation which could be awarded under this plan if all
performance targets and individual objectives were achieved comprised up to 40%
of base salary for executive officers, (other than the Chief Executive
Officer). If performance targets were exceeded, up to 50% of base salary could
be awarded to such officers under this plan. The incentive compensation under
this plan is based on the financial performance of the Company and each
business unit, quantitative departmental goals and the executive officer's
personal performance. Each executive officer (other than those who participate
in the Sales Management Incentive Compensation Plan, as described below) earns
incentive compensation

                                      A-15
<PAGE>

based upon some or all of these areas of performance. The Company and business
unit targets are based upon attaining certain bookings, revenue and operating
profit goals set by the Board of Directors in consultation with the Chief
Executive Officer. Departmental performance is measured by appropriate metrics,
such as on-time completion of key projects, level of quality, and inventory
levels. Compensation for personal performance under this plan is awarded by the
Compensation Committee based upon its objective and subjective evaluation of
the performance of each officer.

   Company and business unit performance bonuses are weighted so that
proportionately higher awards are received when the Company's performance
exceeds targets and proportionately smaller or no awards are made when the
Company does not meet targets. No incentive compensation is paid for Company or
business unit performance unless minimum Company and business unit financial
goals are achieved during the fiscal year.

   In 1998, no compensation was earned by officers under the Management Team
Incentive Compensation Plan.

   The Compensation Committee reviews and adjusts the Management Team Incentive
Compensation Plan annually.

   Sales Management Incentive Compensation Plan. One executive officer of the
Company participated in the Company's Sales Management Incentive Compensation
Plan in 1998. Participation in this plan is in lieu of participation in the
Management Team Incentive Compensation Plan. The total incentive compensation
which could be awarded under this plan if all performance targets were achieved
comprised up to 67% of base salary for the executive officer. If performance
targets were exceeded, up to 100% of base salary could be awarded to the
officer under this plan. Incentive compensation is paid under this plan as a
percentage of bookings and revenue, to the extent that bookings and revenue
exceed 80% of the target goals set by the Board of Directors. In addition, the
executive officer could earn up to 17% of base salary based upon personal
performance. In 1998, compensation earned by the officer who participated in
the Sales Management Incentive Compensation Plan was 25% of the officer's base
salary.

   Gain Sharing Plan. Under this plan, eligible employees (including the
Company's executive officers) may receive quarterly payments based on the
Company's financial results exceeding certain levels. Officers are only
eligible to participate after all other employees have received an annual
allocation of $3,000 per person. No amounts were earned under the Gain Sharing
Plan in 1998.

Long Term Incentive Compensation

   The Compensation Committee believes that long term incentive compensation
through employee equity ownership provides significant additional motivation to
executive officers to maximize value for the Company's stockholders, and
therefore, the Compensation Committee makes periodic grants of stock options
under the Company's option plans. Such options are granted at the prevailing
market price, and will only have value if the Company's stock price increases
over the exercise price. Therefore, the Compensation Committee believes that
stock options serve to align the interest of executive officers closely with
other stockholders because of the direct benefit executive officers receive
through improved stock performance. In addition, stock options vest over time
to provide financial incentive for the executive officers to remain with the
Company.

   In fiscal 1998, the Compensation Committee granted additional options to
executive officers, after consideration of recommendations from the Chief
Executive Officer. Option grants were based upon relative position and
responsibilities of each executive officer, historical and expected
contributions of each executive officer to the Company, and previous option
grants to such executive officers. Options were granted with a goal to provide
equity compensation for the Company's executive officers that is competitive
with equity compensation provided to executive officers with similar positions
in comparably sized companies in similar industries and geographic locations.
All options granted in fiscal 1998 to executive officers in their capacities as
such were granted under the 1994 Option Plan. Generally, option grants under
the 1994 Option Plan vest and become exercisable over four years. Option grants
for fiscal 1998 are set forth in the tables entitled "Option

                                      A-16
<PAGE>

Grants In Last Fiscal Year" in the section entitled "Executive Compensation
And Other Matters" and "Ten Year Option Repricings."

Other Benefits

   The Company's executive officers participate in benefits programs available
generally to all employees.

Chief Executive Officer Compensation

   The compensation of the Chief Executive Officer is based upon the same
criteria outlined above for the other executive officers of the Company. While
the CEO makes recommendations about the compensation levels, goals and
performance of the other executive officers, he does not participate in
discussions regarding his compensation or performance.

   The Compensation Committee did not adjust Mr. Savage's salary in 1998. Mr.
Savage's compensation under the Management Team Incentive Compensation Plan
was based upon the Company achieving financial performance goals. In 1998, Mr.
Savage could have received 50% of his base salary under the Management Team
Incentive Compensation Plan if the Company had met all of its performance
targets and up to 70% if those targets were exceeded by 10% or more. No
incentive compensation was earned by Mr. Savage in 1998. Mr. Savage received
additional option grants under the 1994 Option Plan to purchase 139,000 shares
which included an option grant for 35,000 shares granted in June 1995 which

Report on 1998 Cancellation and Regrant of Options

   In September and November of 1998, the Compensation Committee considered,
separately, the options held by the Company's employees and executive officers
and the fact that a broad decline in the price of the Common Stock of the
Company had resulted in a substantial number of stock options granted having
exercise prices well above the recent historical trading prices for the
Company's Common Stock. The Committee was advised by management that
management believed that key employee turnover was likely to increase in part
because the Company's total compensation package for long-term employees,
which included substantial options with exercise prices well above the current
trading price, was less attractive than compensation offered by other
companies in the same industry and geographic location. This is because
options granted to new hires at other companies would likely be granted at
current trading prices, providing more opportunity for appreciation than the
Company's options.

   The Committee believed that the Company's success in the future would
depend in large part on its ability to retain a number of its highly skilled
technical, managerial and marketing personnel and the loss of key employees
could have significant adverse impact on the Company's business. The Committee
also believed that unless an adjustment was made in option prices, existing
employees holding options would perceive a substantial inequity in comparison
to new employees granted stock options with exercise prices set at the
current, lower fair market value of the Company's Common Stock and that
employee morale would suffer as a consequence. The Committee concluded that it
was important and cost-effective to provide equity incentives to employees and
executive officers of the Company to improve the Company's performance and the
value of the Company for its stockholders. The Committee considered granting
new options selectively to current key employees at fair market value, but
recognized that the size of the option grants required to offset the decline
in market price would result in significant additional dilution to
stockholders. The Committee recognized that

                                     A-17
<PAGE>

canceling existing options with exercise prices higher than fair market value
and regranting options at fair market value would provide additional incentives
to employees because of the increased potential for appreciation. The Committee
also recognized that the new options could require holding periods before they
became exercisable, providing optionees participating in the
cancellation/regrant program with an added incentive to remain with the
Company. Considering these factors, the Committee determined that it was in the
best interests of the Company and its stockholders to restore the incentives
for employees and executive officers to remain as employees of the Company and
to exert their maximum efforts on behalf of the Company by canceling and
regranting stock options under the Option Plan for those options with exercise
prices above recent trading prices.

   In September 1998, the Compensation Committee approved the cancellation and
regrant of all outstanding options granted to non-officer employees at exercise
prices exceeding the fair market value of common stock as of October 23, 1998,
the effective date of the program. The exercise price of each regranted option
is $2.75, which is the closing market price of the Company's common stock on
October 23, 1998. Each optionee holding such an option had the opportunity to
(i) elect to retain the old option or (ii) accept a new option with an exercise
price equal to the fair market value of the Company's common stock on the
effective date and cancel the old option. Each regranted option covered the
same number of shares subject to the old option at the time of cancellation and
maintained the same vesting period as the previously canceled option. The
regranted options cannot be exercised for a period of six months following the
effective date. Any employee voluntarily leaving the Company during the six
month period will lose the affected options, including previously vested
portions of those options. All replacement options will terminate no later than
ten (10) years from the date of grant. Options to purchase a total of 1,706,275
shares of the Company's Common Stock at exercise prices ranging from $2.80 per
share to $9.88 per share have been canceled in exchange for regranted options
for an equal number of shares at an exercise price of $2.75 per share, the
closing price of the Company's Common Stock on the effective date of the
program.

   In November 1998, the Compensation Committee of the Company's Board of
Directors approved the cancellation and regrant of all outstanding options
granted to executive officers at exercise prices exceeding the fair market
value of common stock as of November 6, 1998, the effective date of the
program. The exercise price of each regranted option is $2.75, which was the
closing market price of the Company's common stock on November 6, 1998. Each
executive officer holding such an option had the opportunity to (i) elect to
retain the old option or (ii) accept two new options with exercise prices equal
to the fair market value of the Company's common stock on the effective date
and cancel the old option. Each regranted option covered one-half of the number
of shares subject to the old option at the time of cancellation. One of the
regranted options maintained the same vesting period as the previously canceled
option. The other regranted option vests in equal monthly installments over a
48 month period beginning on the grant date. The regranted options are subject
to the condition that the options cannot be exercised for a period of six
months following the effective date. Any executive officer voluntarily leaving
the Company during the six month period will lose the affected options,
including previously vested portions of those options. All replacement options
will terminate no later than ten (10) years from the date of grant. Options to
purchase a total of 1,706,275 shares of the Company's Common Stock at exercise
prices ranging from $4.75 per share to $15.25 per share have been canceled in
exchange for regranted options for an equal number of shares at an exercise
price of $2.75 per share, the closing price of the Company's Common Stock on
the effective date of the program.

   The Compensation Committee believes the regranted options strike an
appropriate balance between the interests of the option holders and those of
the stockholders. The lower exercise prices in effect under the regranted
options make those options valuable to the executive officers and employees
critical to the Company's financial performance. However, those individuals
will enjoy the benefits of the regranted options only if they remain in the
Company's employ and contribute to the Company's and investor's financial
success.

                           TEN YEAR OPTION REPRICINGS

   The table below sets forth (i) information with respect to each of the
Company's named executive officers concerning his participation in the option
cancellation/regrant program which was effected November 6, 1998 and (ii)
information with respect to all former or current executive officers of the
Company concerning their participation in other option repricing programs
implemented by the Company during the last ten fiscal years. Options referenced
in the table below that were repriced on November 6, 1998 represent two new
option agreements. Each such option agreement is for one-half of the number of
shares subject to the old option at the time of cancellation. One of the
regranted options maintained the same vesting period as the previously canceled
option, and the other regranted option vests in equal monthly installments over
a 48-month period beginning on the date of repricing.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

   Section 16(a) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), requires the Company's executive officers and directors and
persons who own more than ten percent of a registered class of the Company's
equity securities to file reports of ownership on Form 3 and changes in
ownership on Form 4 or Form 5 with the Securities and Exchange Commission (the
"SEC"). Such officers, directors and ten percent stockholders are also required
by SEC rules to furnish the Company with copies of all Section 16(a) reports
they file.

   Based solely on its review of the copies of such forms received by it, the
Company believes that all reporting persons complied with Section 16(a) filing
requirements applicable to them.

   September 7, 1999

   Board of Directors
   Applied Digital Access, Inc.
   9855 Scranton Road
   San Diego, CA 92121

   You have requested our opinion as to the fairness, from a financial point
of view, to the stockholders of Applied Digital Access, Inc. ("ADA") for the
consideration received in the acquisition (the "Acquisition") of ADA by
Dynatech Corporation ("Dynatech"). As contemplated by the Agreement and Plan
of Merger (the "Agreement"), dated September 7, 1999, the stockholders of ADA
will receive Total Cash Consideration of approximately $80 million in Cash, or
$5.37 per share.

   For purposes of the opinion set forth herein, we have:

     (a) Reviewed financial statements and other information of ADA;

     (b) Reviewed certain internal financial statements and other financial
  and operating data concerning ADA prepared by the management of ADA;

     (c) Analyzed certain financial projections prepared by the management of
  ADA;

     (d) Discussed the past and current operations, financial condition, and
  the prospects of ADA with senior executives of ADA;

     (e) Discussed with the senior management of ADA the strategic objectives
  of the Acquisition and the strategic alternatives available to ADA;

     (f) Compared the financial performance of ADA with that of certain other
  comparable publicly-traded companies and the prices paid for securities in
  those publicly-traded companies;

     (g) Reviewed the financial terms, to the extent publicly available, of
  certain comparable acquisition transactions;

     (h) Assessed ADA's forecast and future cash flows for a discounted cash
  flow analysis;

     (i) Reviewed the Agreement and Plan of Merger, and certain related
  documents; and

     (j) Performed such other analyses and considered such other factors as
  we have deemed appropriate.

   We have assumed and relied upon, without independent verification, the
accuracy and completeness of the information reviewed by us for the purposes
of this opinion. With respect to the financial projections of ADA, we have
assumed that they have been reasonably prepared on bases reflecting the best
currently available estimates and judgments of the future financial
performance of ADA. The financial and other information regarding ADA reviewed
by Alliant Partners in connection with the rendering of this opinion was
limited to information provided by ADA's management and certain discussions
with ADA's senior management regarding ADA's financial condition and prospects
and their strategic objectives of the Acquisition as well as the strategic
alternatives available to ADA. In addition, we have assumed that the
Acquisition will be consummated in accordance with the terms set forth in the
Agreement. We have not made any independent valuation or appraisal of the
assets or liabilities of ADA, nor have we been furnished with any such
appraisals. Our opinion is necessarily based on economic, market and other
conditions as in effect on, and the information made available to us as of the
date hereof.

                                      B-1
<PAGE>

   Our opinion addresses only the fairness of the transaction, from a financial
point of view, to the stockholders of ADA, and we do not express any views on
any other terms of the Agreement or the business bases underlying the
Agreement.

   Alliant Partners has received fees from ADA for previous advisory
engagements as well as a fee for this transaction.

   Based upon and subject to the foregoing, and based upon such other matters
as we consider relevant, it is our opinion that, as of the date hereof, the
cash consideration received by the ADA stockholders pursuant to the Agreement
is fair, from a financial point of view, to the ADA stockholders.

                                          Very truly yours,

                                          Alliant Partners
