(1)  The shares of Common Stock being registered represent 130,000 shares of
     Common Stock which may be acquired pursuant to options available for grant
     in the future under the ADTRAN, Inc. 1995 Directors  Stock Option Plan (the
     "Plan"). The initial 70,000 shares of Common Stock reserved for issuance
     under the Plan were registered under a Registration Statement (Commission
     File No. 333-4808) that became effective on April 26, 1996.  An
     undetermined number of additional shares may be issued, or the shares
     registered hereunder may be combined into an undetermined lesser number of
     shares, if the antidilution provisions of the Plan become operative.

(2)  The offering price of the 130,000 shares which may be acquired pursuant to
     options available for grant in the future under the Plan is not presently
     determinable. The offering price for such shares is estimated pursuant to
     Rule 457(c) and (h) solely for the purpose of calculating the registration
     fee and is based upon the average of the high and low prices of the
     Registrant's Common Stock on May 7, 1999 as quoted on The Nasdaq
     National Market.

          INCORPORATION BY REFERENCE OF EARLIER REGISTRATION STATEMENT


     This Registration Statement relates, in part, to the amendment of the Plan
to increase the number of shares of Common Stock authorized to be issued under
the Plan from 70,000 to 200,000.  An earlier Registration Statement filed on
Form S-8 (Commission File No. 333-4808) covering 70,000 shares of Common Stock
issuable under the Plan is effective.  Pursuant to General Instruction E to Form
S-8, the contents of the earlier Registration Statement are incorporated herein
by reference.

                                     PART I

              INFORMATION REQUIRED IN THE SECTION 10(a) PROSPECTUS

     The documents containing the information specified in the instructions to
Part I of the Registration Statement on Form S-8 will be sent or given to
participants in the Plan as required by Rule 428(b)(1) of the rules promulgated
under the Securities Act of 1933, as amended.  As permitted by the instructions
to Part I of the Registration Statement on Form S-8, such documents are not
filed with this Registration Statement.

                                    PART II

               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT


Item 3.   Incorporation of Documents by Reference
          ---------------------------------------

     The following documents heretofore filed by ADTRAN, Inc. (the "Company" or
the "Registrant") with the Securities and Exchange Commission (the "Commission")
hereby are incorporated herein by reference as of their respective dates:

     (1) The Company's Annual Report on Form 10-K for the year ended December
31, 1998; and

     (2) The description of the Company's Common Stock as contained in the
Company's Registration Statement on Form 8-A (Registration No. 0-24612) as
declared effective by the Commission on August 9, 1994.

     In addition, all reports and documents subsequently filed by the Company
pursuant to Sections 13(a), 13(c), 14 or 15(d) of the Securities Exchange Act of
1934, as amended (the "1934 Act") subsequent to the date hereof and prior to the
filing of a post-effective amendment which indicates that all securities offered
hereby have been sold or which deregisters all securities then remaining unsold,
shall be deemed to be incorporated by reference herein and made a part hereof
from the date of the filing of such documents.

Item 6.   Indemnification of Directors and Officers
          -----------------------------------------

     Article Eleventh of the Company's Certificate of Incorporation provides for
the elimination of personal monetary liabilities of directors of the Company for
breaches of their fiduciary duties as directors, except that, as provided by
Section 102(b)(7) of the General Corporation Law of Delaware (the "GCL"), such
personal monetary liability of a director may not be eliminated with regard to
any breach of the duty of loyalty, failing to act in good faith, intentional
misconduct or knowing violation of law, payment of an unlawful dividend,
approval of an illegal stock repurchase, or obtainment of an improper personal
benefit. Such a provision has no effect on the availability of equitable
remedies, such as an injunction or rescission, for breach of fiduciary duty.

     Article Twelfth of the Company's Certificate of Incorporation provides for
indemnification of directors and officers of the Company to the extent permitted
by the GCL. Section 145 of the GCL provides for indemnification of directors
and officers from and against expenses (including attorney's fees), judgments,
fines and amounts paid in settlement reasonably incurred by them in connection
with any civil, criminal, administrative or investigative claim or proceeding
(including civil actions brought as derivative actions by or in the right of the
corporation but only to the extent of expenses reasonably incurred in defending
or settling such action) in which they may become involved by reason of being a
director or officer of the corporation if the director or officer acted in good
faith and in a manner which he reasonably believed to be in or not opposed to
the best interest of the corporation and, in addition, in criminal actions, if
he had no reasonable cause to believe his conduct to be unlawful.  If, in an
action brought by or in the right of the corporation, the director or officer is
adjudged to be liable for negligence or misconduct in the performance of his
duty, he will only be entitled to such indemnity as the court finds to be
proper.  Persons who are successful in defense of any claim against them are
entitled to indemnification as of right against expenses actually and reasonably
incurred in connection therewith.  In all other cases, indemnification shall be
made (unless otherwise ordered by a court) only if the board of directors,
acting by a majority vote of a quorum of disinterested directors, independent
legal counsel or holders of a majority of the shares entitled to vote determines
that the applicable standard of conduct has been met. Section 145 also provides
such indemnity for directors and officers of a corporation who, at the request
of the corporation, act as directors, officers, employees or agents of other
corporations, partnerships or other enterprises.
<PAGE>
 
     Article VI of the Company's Bylaws provides as follows:

          Section 6.1.  Indemnification.  The Corporation shall indemnify and
                        ---------------                                      
     advance expenses to any officer, director, employee or agent to the full
     extent permitted by its Certificate of Incorporation, these bylaws or by
     law.

     The Company maintains directors and officers liability insurance which will
insure against liabilities that directors or officers of the Company may incur
in such capacities.

Item 9.   Undertakings
          ------------

          A.   Rule 415 Offering.

          The undersigned Registrant hereby undertakes:

          (1) To file, during any period in which offers or sales are being
made, a post-effective amendment to this registration statement to include any
material information with respect to the plan of distribution not previously
disclosed in the registration statement or any material change to such
information in the registration statement.

          (2) That, for the purpose of determining any liability under the
Securities Act of 1933, as amended (the "1933 Act"), each such post-effective
amendment shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.

          (3) To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination of
the offering.


          B.   Subsequent Documents Incorporated by Reference.

          The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the 1933 Act, each filing of the Registrant's
annual report pursuant to Section 13(a) or Section 15(d) of the 1934 Act that is
incorporated by reference in the registration statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.
<PAGE>
 
          C.   Indemnification of Officers, Directors and Controlling Persons.

          Insofar as indemnification for liabilities arising under the 1933 Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions described under Item 6 above, or
otherwise, the Registrant has been advised that in the opinion of the Commission
such indemnification is against public policy as expressed in the 1933 Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the 1933 Act and will be governed by the final
adjudication of such issue.

     Common Stock which may be acquired pursuant to options available for grant
     in the future under the ADTRAN, Inc. 1995 Directors  Stock Option Plan (the
     "Plan"). The initial 70,000 shares of Common Stock reserved for issuance
     under the Plan were registered under a Registration Statement (Commission
     File No. 333-4808) that became effective on April 26, 1996.  An
     undetermined number of additional shares may be issued, or the shares
     registered hereunder may be combined into an undetermined lesser number of
     shares, if the antidilution provisions of the Plan become operative.

(2)  The offering price of the 130,000 shares which may be acquired pursuant to
     options available for grant in the future under the Plan is not presently
     determinable. The offering price for such shares is estimated pursuant to
     Rule 457(c) and (h) solely for the purpose of calculating the registration
     fee and is based upon the average of the high and low prices of the
     Registrant's Common Stock on May 7, 1999 as quoted on The Nasdaq
     National Market.
INCORPORATION BY REFERENCE OF EARLIER REGISTRATION STATEMENT

     This Registration Statement relates, in part, to the amendment of the Plan
to increase the number of shares of Common Stock authorized to be issued under
the Plan from 70,000 to 200,000.  An earlier Registration Statement filed on
Form S-8 (Commission File No. 333-4808) covering 70,000 shares of Common Stock
issuable under the Plan is effective.  Pursuant to General Instruction E to Form
S-8, the contents of the earlier Registration Statement are incorporated herein
by reference.

                                     PART I

              INFORMATION REQUIRED IN THE SECTION 10(a) PROSPECTUS

     The documents containing the information specified in the instructions to
Part I of the Registration Statement on Form S-8 will be sent or given to
participants in the Plan as required by Rule 428(b)(1) of the rules promulgated
under the Securities Act of 1933, as amended.  As permitted by the instructions
to Part I of the Registration Statement on Form S-8, such documents are not
filed with this Registration Statement.
PART II

               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

Item 3.   Incorporation of Documents by Reference
          ---------------------------------------

     The following documents heretofore filed by ADTRAN, Inc. (the "Company" or
the "Registrant") with the Securities and Exchange Commission (the "Commission")
hereby are incorporated herein by reference as of their respective dates:

     (1) The Company's Annual Report on Form 10-K for the year ended December
31, 1998; and

     (2) The description of the Company's Common Stock as contained in the
Company's Registration Statement on Form 8-A (Registration No. 0-24612) as
declared effective by the Commission on August 9, 1994.

     In addition, all reports and documents subsequently filed by the Company
pursuant to Sections 13(a), 13(c), 14 or 15(d) of the Securities Exchange Act of
1934, as amended (the "1934 Act") subsequent to the date hereof and prior to the
filing of a post-effective amendment which indicates that all securities offered
hereby have been sold or which deregisters all securities then remaining unsold,
shall be deemed to be incorporated by reference herein and made a part hereof
from the date of the filing of such documents.

Item 6.   Indemnification of Directors and Officers
          -----------------------------------------

     Article Eleventh of the Company's Certificate of Incorporation provides for
the elimination of personal monetary liabilities of directors of the Company for
breaches of their fiduciary duties as directors, except that, as provided by
Section 102(b)(7) of the General Corporation Law of Delaware (the "GCL"), such
personal monetary liability of a director may not be eliminated with regard to
any breach of the duty of loyalty, failing to act in good faith, intentional
misconduct or knowing violation of law, payment of an unlawful dividend,
approval of an illegal stock repurchase, or obtainment of an improper personal
benefit. Such a provision has no effect on the availability of equitable
remedies, such as an injunction or rescission, for breach of fiduciary duty.

     Article Twelfth of the Company's Certificate of Incorporation provides for
indemnification of directors and officers of the Company to the extent permitted
by the GCL. Section 145 of the GCL provides for indemnification of directors
and officers from and against expenses (including attorney's fees), judgments,
fines and amounts paid in settlement reasonably incurred by them in connection
with any civil, criminal, administrative or investigative claim or proceeding
(including civil actions brought as derivative actions by or in the right of the
corporation but only to the extent of expenses reasonably incurred in defending
or settling such action) in which they may become involved by reason of being a
director or officer of the corporation if the director or officer acted in good
faith and in a manner which he reasonably believed to be in or not opposed to
the best interest of the corporation and, in addition, in criminal actions, if
he had no reasonable cause to believe his conduct to be unlawful.  If, in an
action brought by or in the right of the corporation, the director or officer is
adjudged to be liable for negligence or misconduct in the performance of his
duty, he will only be entitled to such indemnity as the court finds to be
proper.  Persons who are successful in defense of any claim against them are
entitled to indemnification as of right against expenses actually and reasonably
incurred in connection therewith.  In all other cases, indemnification shall be
made (unless otherwise ordered by a court) only if the board of directors,
acting by a majority vote of a quorum of disinterested directors, independent
legal counsel or holders of a majority of the shares entitled to vote determines
that the applicable standard of conduct has been met. Section 145 also provides
such indemnity for directors and officers of a corporation who, at the request
of the corporation, act as directors, officers, employees or agents of other
corporations, partnerships or other enterprises.
Article VI of the Company's Bylaws provides as follows:

          Section 6.1.  Indemnification.  The Corporation shall indemnify and
                        ---------------                                      
     advance expenses to any officer, director, employee or agent to the full
     extent permitted by its Certificate of Incorporation, these bylaws or by
     law.

     The Company maintains directors and officers liability insurance which will
insure against liabilities that directors or officers of the Company may incur
in such capacities.

Item 9.   Undertakings
          ------------

          A.   Rule 415 Offering.

          The undersigned Registrant hereby undertakes:

          (1) To file, during any period in which offers or sales are being
made, a post-effective amendment to this registration statement to include any
material information with respect to the plan of distribution not previously
disclosed in the registration statement or any material change to such
information in the registration statement.

          (2) That, for the purpose of determining any liability under the
Securities Act of 1933, as amended (the "1933 Act"), each such post-effective
amendment shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.

          (3) To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination of
the offering.

          B.   Subsequent Documents Incorporated by Reference.

          The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the 1933 Act, each filing of the Registrant's
annual report pursuant to Section 13(a) or Section 15(d) of the 1934 Act that is
incorporated by reference in the registration statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.
C.   Indemnification of Officers, Directors and Controlling Persons.

          Insofar as indemnification for liabilities arising under the 1933 Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions described under Item 6 above, or
otherwise, the Registrant has been advised that in the opinion of the Commission
such indemnification is against public policy as expressed in the 1933 Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the 1933 Act and will be governed by the final
adjudication of such issue.
