        This Registration Statement on Form S-8 relates to the registration of

including the associated preferred share purchase rights, of Teltrend Inc. (the
"Company" or the "Registrant").

Securities and Exchange Commission (the "Commission") are hereby incorporated
by reference into this Registration Statement and made a part hereof:

        (f) The descriptions of the Common Stock and associated
            preferred share purchase rights contained in the Company's
            Registration Statements on Form 8-A, originally filed with the
            Commission on May 23, 1995 and January 27, 1997, respectively,
            including any amendment or report filed for the purpose of updating
            such description.

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

        Any statement, including financial statements, contained in a document
incorporated or deemed to be incorporated by reference herein shall be deemed
to be modified or superseded for purposes of this Registration Statement to the

ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL.

        Not applicable.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

        The Company's Restated Certificate of Incorporation, as amended (the
"Restated Certificate of Incorporation"), provides that, pursuant to Delaware
law, no director of the Company shall be liable to the Company or its
stockholders for monetary damages for breach of fiduciary duty as a director.
This provision does not eliminate a director's fiduciary duty, and in
appropriate circumstances equitable remedies such as injunctive or other forms
of non-monetary relief will remain available under Delaware law.  In addition,
this provision shall not limit or eliminate the liability of a director for:
(i) breach of the director's duty of loyalty to the Company or its
stockholders; (ii) acts or omissions not in good faith or which involve
intentional misconduct or knowing violations of law; (iii) any transaction from
which the director derived an improper personal benefit; and (iv) payment of
dividends or approval of stock repurchases or redemptions that are unlawful
under Delaware law.  The provision also does not affect a director's
responsibilities under any other law, such as the federal securities laws.
Reference is made to Section 102(b)(7) of the General Corporation Law of the
State of Delaware (the "DGCL").

        Reference is made to Section 145 of the DGCL which provides for
indemnification of directors and officers.  The Company's Restated Certificate
of Incorporation and its Amended and Restated Bylaws (the "Bylaws") provide
that the Company will indemnify its directors and executive officers to the
fullest extent permitted by the DGCL as it currently exists or may thereafter
be amended.  The Bylaws also provide that the Company has no obligation to
indemnify any director or executive officer of the Company for expenses or
payments of profits arising from the purchase and sale by any such person of
securities in violation of Section 16(b) of the Exchange Act.  In addition, the
Company has entered into separate indemnification agreements with each of its
directors and executive officers which may require the Company, among other
things, to indemnify them against certain liabilities that may arise by reason
of their status or service as directors or executive officers and to advance
their expenses incurred as a result of any proceeding against them as to which
they could be indemnified.

        The Company has in force an insurance policy which insures the officers
and directors of the Company against certain liabilities incurred by them in
the discharge of their functions as such officers and directors, within the
limits and subject to the limitations of the policy.

        On June 8, 1995 and October 24, 1995, the Company entered into
underwriting agreements (the "Underwriting Agreements") with the underwriters
of the 1995 public offerings of the Company's Common Stock.  Pursuant to the
Underwriting Agreement for each offering, the Company agreed to indemnify the
underwriters of such offering and such underwriters agreed to indemnify the
Company against certain liabilities, including liabilities under the Act.  The
Underwriting Agreement for each offering also provides for indemnification of
directors, officers and controlling persons of the Company by the underwriters
of such offering against certain liabilities, including certain liabilities
under the Act.

        The Company is party to a Registration Rights and Lock-Up Agreement, 
dated as of April 10, 1995, with certain of its stockholders (the "Registration
Agreement").  Pursuant to the Registration Agreement, these stockholders have
certain rights to have specified shares of the Company's equity securities
registered under the Act.  Each stockholder who is party to the Registration
Agreement has agreed to indemnify each director, officer and controlling person
of the Company against liabilities related to such stockholder's statements or
omissions in connection with any registration of such stockholder's shares
pursuant to the terms of the Registration Statement.

ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED.

        Not applicable.

ITEM 8. EXHIBITS.

ITEM 9. UNDERTAKINGS.

1.      The undersigned Registrant hereby undertakes:


        a. To file, during any period in which offers or sales are being made of
        the securities registered hereby, a post-effective amendment to this
        Registration Statement:

           (i) To include any prospectus required by Section 10(a)(3) of the
           Act;

           (ii) To reflect in the prospectus any facts or events arising after  
           the effective date of the Registration Statement (or the most recent
           post-effective amendment thereof) which, individually or in the
           aggregate, represent a fundamental change in the information set
           forth in this Registration Statement (notwithstanding the foregoing,
           any increase or decrease in the volume of securities offered (if the
           total dollar value of securities offered would not exceed that which
           was registered) and any deviation from the low or high and of the
           estimated maximum offering range may be reflected in the form of
           prospectus filed with the Commission pursuant to Rule 424(b) if, in
           the aggregate, the changes in volume and price represent no more
           than 20 percent change in the maximum aggregate offering price set
           forth in the "Calculation of Registration Fee" table in the
           effective registration statement);

                                     -4-


<PAGE>   5



           (iii) 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 this
           Registration Statement;

        provided, however, that paragraphs (i) and (ii) above do not apply if   
        the information required to be included in a post-effective amendment
        by those paragraphs is contained in periodic reports filed with or
        furnished to the Commission by the Registrant pursuant to Section 13 or
        15(d) of the Exchange Act that are incorporated by reference in the
        Registration Statement.

        b. That, for the purpose of determining any liability under the Act,    
        each such post-effective amendment shall be deemed to be a new
        registration statement relating to the securities offered herein, and
        the offering of such securities at that time shall be deemed to be the
        initial bona fide offering thereof.

        c. 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.

2.      The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Act, each filing of the Registrant's annual
report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where
applicable, each filing of an employee benefit plan's annual report pursuant to
Section 15(d) of the Exchange Act) that is incorporated by reference in this
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.

3.      The undersigned Registrant hereby undertakes that, insofar as
indemnification for liabilities arising under the Act may be permitted to
directors, officers and controlling persons of the Registrant pursuant to the
foregoing provisions, or otherwise, the Registrant has been advised that in the
opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the 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 Act and will be governed by the final adjudication of such
issue.

        This Registration Statement on Form S-8 relates to the registration of

including the associated preferred share purchase rights, of Teltrend Inc. (the
"Company" or the "Registrant").

        The following documents heretofore filed by the Company with the
Securities and Exchange Commission (the "Commission") are hereby incorporated
by reference into this Registration Statement and made a part hereof:

        (a) The Company's Annual Report on Form 10-K for the fiscal year ended 
            July 27, 1996;

            and April 18, 1997;

        (d) The Company's Quarterly Report on Form 10-Q for the quarter ended

        (e) The Company's Quarterly Report on Form 10-Q for the quarter ended

        (f) The descriptions of the Common Stock and associated
            preferred share purchase rights contained in the Company's
            Registration Statements on Form 8-A, originally filed with the
            Commission on May 23, 1995 and January 27, 1997, respectively,
            including any amendment or report filed for the purpose of updating
            such description.

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

        Any statement, including financial statements, contained in a document
incorporated or deemed to be incorporated by reference herein shall be deemed
to be modified or superseded for purposes of this Registration Statement to the
extent that a statement contained herein, or in any other subsequently filed

modifies or supersedes such statement.  Any such statement so modified or
superseded shall not be deemed, except as so modified or superseded, to

ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL.

        Not applicable.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

        The Company's Restated Certificate of Incorporation, as amended (the
"Restated Certificate of Incorporation"), provides that, pursuant to Delaware
law, no director of the Company shall be liable to the Company or its
stockholders for monetary damages for breach of fiduciary duty as a director.
This provision does not eliminate a director's fiduciary duty, and in
appropriate circumstances equitable remedies such as injunctive or other forms
of non-monetary relief will remain available under Delaware law.  In addition,
this provision shall not limit or eliminate the liability of a director for:
(i) breach of the director's duty of loyalty to the Company or its
stockholders; (ii) acts or omissions not in good faith or which involve
intentional misconduct or knowing violations of law; (iii) any transaction from
which the director derived an improper personal benefit; and (iv) payment of
dividends or approval of stock repurchases or redemptions that are unlawful
under Delaware law.  The provision also does not affect a director's
responsibilities under any other law, such as the federal securities laws.
Reference is made to Section 102(b)(7) of the General Corporation Law of the
State of Delaware (the "DGCL").

        Reference is made to Section 145 of the DGCL which provides for
indemnification of directors and officers.  The Company's Restated Certificate
of Incorporation and its Amended and Restated Bylaws (the "Bylaws") provide
that the Company will indemnify its directors and executive officers to the
fullest extent permitted by the DGCL as it currently exists or may thereafter
be amended.  The Bylaws also provide that the Company has no obligation to
indemnify any director or executive officer of the Company for expenses or
payments of profits arising from the purchase and sale by any such person of
securities in violation of Section 16(b) of the Exchange Act.  In addition, the
Company has entered into separate indemnification agreements with each of its
directors and executive officers which may require the Company, among other
things, to indemnify them against certain liabilities that may arise by reason
of their status or service as directors or executive officers and to advance
their expenses incurred as a result of any proceeding against them as to which
they could be indemnified.

        The Company has in force an insurance policy which insures the officers
and directors of the Company against certain liabilities incurred by them in
the discharge of their functions as such officers and directors, within the
limits and subject to the limitations of the policy.

        On June 8, 1995 and October 24, 1995, the Company entered into
underwriting agreements (the "Underwriting Agreements") with the underwriters
of the 1995 public offerings of the Company's Common Stock.  Pursuant to the
Underwriting Agreement for each offering, the Company agreed to indemnify the
underwriters of such offering and such underwriters agreed to indemnify the
Company against certain liabilities, including liabilities under the Act.  The
Underwriting Agreement for each offering also provides for indemnification of
directors, officers and controlling persons of the Company by the underwriters
of such offering against certain liabilities, including certain liabilities
under the Act.

        The Company is party to a Registration Rights and Lock-Up Agreement, 
dated as of April 10, 1995, with certain of its stockholders (the "Registration
Agreement").  Pursuant to the Registration Agreement, these stockholders have
certain rights to have specified shares of the Company's equity securities
registered under the Act.  Each stockholder who is party to the Registration
Agreement has agreed to indemnify each director, officer and controlling person
of the Company against liabilities related to such stockholder's statements or
omissions in connection with any registration of such stockholder's shares
pursuant to the terms of the Registration Statement.

ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED.

ITEM 9. UNDERTAKINGS.

1.      The undersigned Registrant hereby undertakes:

        a. To file, during any period in which offers or sales are being made of
        the securities registered hereby, a post-effective amendment to this
        Registration Statement:

           (i) To include any prospectus required by Section 10(a)(3) of the
           Act;

           (ii) To reflect in the prospectus any facts or events arising after  
           the effective date of the Registration Statement (or the most recent
           post-effective amendment thereof) which, individually or in the
           aggregate, represent a fundamental change in the information set
           forth in this Registration Statement (notwithstanding the foregoing,
           any increase or decrease in the volume of securities offered (if the
           total dollar value of securities offered would not exceed that which
           was registered) and any deviation from the low or high and of the
           estimated maximum offering range may be reflected in the form of
           prospectus filed with the Commission pursuant to Rule 424(b) if, in
           the aggregate, the changes in volume and price represent no more
           than 20 percent change in the maximum aggregate offering price set
           forth in the "Calculation of Registration Fee" table in the
           effective registration statement);

                                     -4-
5

           (iii) 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 this
           Registration Statement;

        provided, however, that paragraphs (i) and (ii) above do not apply if   
        the information required to be included in a post-effective amendment
        by those paragraphs is contained in periodic reports filed with or
        furnished to the Commission by the Registrant pursuant to Section 13 or
        15(d) of the Exchange Act that are incorporated by reference in the
        Registration Statement.

        b. That, for the purpose of determining any liability under the Act,    
        each such post-effective amendment shall be deemed to be a new
        registration statement relating to the securities offered herein, and
        the offering of such securities at that time shall be deemed to be the
        initial bona fide offering thereof.

        c. 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.

2.      The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Act, each filing of the Registrant's annual
report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where
applicable, each filing of an employee benefit plan's annual report pursuant to
Section 15(d) of the Exchange Act) that is incorporated by reference in this
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.

3.      The undersigned Registrant hereby undertakes that, insofar as
indemnification for liabilities arising under the Act may be permitted to
directors, officers and controlling persons of the Registrant pursuant to the
foregoing provisions, or otherwise, the Registrant has been advised that in the
opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the 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 Act and will be governed by the final adjudication of such
issue.
