    ITEM 5.       OTHER EVENTS

         On December 13, 1999, Westell Technologies, Inc. ("Westell") released a
         Press Release, a copy of which is attached as Exhibit 99.1 to this Form
         8-K and incorporated herein by reference,  which announced the proposed
         merger  of  a  subsidiary  of  Westell  with  and  into  Teltrend  Inc.
         ("Teltrend").  A copy of the Merger  Agreement  related to the proposed
         transaction is attached hereto as Exhibit 99.2.

         The merger is  subject to  conditions  to  closing  including,  without
         limitation,   approval   of  the   Merger   Agreement   by   Teltrend's
         stockholders;  the  approval of  Westell's  stock  issuance and related
         transactions  by Westell's  stockholders;  and the receipt of antitrust
         clearances.

         In connection with the Merger Agreement, Robert C. Penny III and Melvin
         J. Simon,  who together  currently  hold voting  power over  18,907,908
         shares  of  Westell's  Class  B  common  stock  (approximately  80%  of
         Westell's  current  total  outstanding  voting  power),  entered into a
         Voting  Agreement with Teltrend.  Under the Voting  Agreement,  Messrs.
         Penny and Simon have  agreed,  individually  and as trustees of various
         trusts holding  Westell stock, to vote all shares of Westell stock over
         which  they  have  direct  or  indirect  voting  power  in favor of the
         merger-related transactions if a majority of those Westell stockholders
         who are  neither  directors  or  officers of Westell nor members of the
         Penny or Simon families vote in favor of these transactions.  A copy of
         the Voting Agreement is attached hereto as Exhibit 99.3.


         Also in  connection  with the proposed  transaction,  Westell  executed
         letter  agreements  with the  holders of its  outstanding  Subordinated
         Secured  Convertible  Debentures.  Pursuant to these letter agreements,
         copies  of which  are  attached  hereto as  Exhibits  99.4(a)-(c),  the
         holders of the  debentures and related  warrants  waived certain rights
         which could  arise in  connection  with the  proposed  transaction  and
         Westell  amended  the  exercise  price of the  warrants  to $5.9208 per
         share.
