AURORA,  IL  ...(DECEMBER  13,  1999)...  Robert H.  Gaynor,  Chairman and Chief
Executive Officer,  announced today, that Westell Technologies (NASDAQ: WSTL), a
leading  provider of DSL  technology,  telecommunications  access  products  and
hosted and managed  conferencing  and support  services  has signed a definitive
agreement to acquire Teltrend Corporation (NASDAQ:  TLTN).  Teltrend Corporation
designs,  manufactures and markets a broad range of telecommunications  and data
communications  products used by businesses  and telephone  companies to provide
voice and data services.

Teltrend, established in 1979, manufactures and markets products to provide data
and voice services over the existing telephone  network,  primarily in the Local
Loop.  Teltrend's unique local telephone loop solutions -developed for HDSL, T1,
Fiber Optic,  ISDN, DDS, and DLC  applications  -- allow telephone  companies to
provide new and better services to their  customers  without the need for costly
infrastructure replacement.  Teltrend also manufactures a wide range of products
that convert,  change and amplify transmission  protocols and are used worldwide
in public and private communications networks.

By merging  Teltrend with  Westell's  HiCap Business Unit, the Company will be a
leader in local loop solutions  including T1, Fiber Optic,  ISDN,  DDS, HDSL and
DLC applications serving virtually the entire carrier market. Westell expects to
realize  significant  synergies  as a result  of the  transaction,  including  a
decrease in combined operating expenses,  increases in operating  leverage,  and
expanded strength in its sales channel . The combined Company's headquarters and
manufacturing facility will be based in Aurora, Illinois and will have more than
1,000 employees.

Marc Zionts,  Chief Executive  Officer of Westell,  stated that "Teltrend brings
outstanding   products,   people  and  customers  to  the  Westell  family.  The
combination of Westell and Teltrend will provide enormous benefits. We will fuel
our DSL initiatives  while at the same time build a stronger  operating base and
increase our scale."

J. Nelson Westell Inc.,  President and COO,  remarked "Both Teltrend and Westell
have been in the business of providing  local access  solutions to our customers
for many  years.  We  believe  we will  realize a high  degree of synergy in our
companies enabling the combined entity to more effectively serve the market with
an expanded product portfolio.  This exciting  combination will also allow us to
further broaden our DSL programs."

"Teltrend  is very  pleased to join the  Westell  team",  stated  Howard  Kirby,
Chairman  and Chief  Executive  Officer  of  Teltrend.  "Westell's  high  growth
initiatives,  innovation,  and presence in the  marketplace  provide a great fit
with Teltrend.  Our  shareholders,  customers and employees will benefit from an
increased presence in our core business and expansion into the DSL arena."

Under the terms of the  agreement,  each share of Teltrend  common stock will be
exchanged for 3.3 shares of Class A Westell  common stock.  Based on the closing
price of Westell shares on December 10, the aggregate  value of the  transaction
to Westell stockholders is $205 million.





The merger,  approved by the boards of  directors of both  companies,  will also
require the  approval  of both  Westell's  and  Teltrend's  stockholders  and is
subject to regulatory approvals and other customary conditions.  The transaction
is expected to be accounted for using  purchase  accounting  and to qualify as a
tax-free reorganization.  Westell Technologies expects to take a one-time charge
for merger and related  expenses  upon the closing of the deal which is expected
to occur in the fourth quarter of Westell's Fiscal Year 2000.  Goldman,  Sachs &
Co. and Hambrecht & Quist acted as Westell's  financial advisors while Soundview
