              TCSI Corporation Reports Third Quarter Results

ALAMEDA,  California - October 15, 1997 - TCSI Corporation  (Nasdaq:  TCSI)
reported today revenues for the third quarter ended September 30,  1997  in
the amount of $9.8 million, up by 13 percent from telecom revenues reported
in  the  third  quarter  of 1996.  Accompanying the  improvement  in  third
quarter telecom revenues was a net loss of $0.5 million, or $0.02 cents per
share,  reflecting an improvement over the net loss of $6.5 million,  or  a
loss  of  $0.31  per share, reported in the comparable 1996 quarter.   When
compared  to  total revenues reported in the third quarter of  1996,  which
included  $1.2  million from discontinued non-telecom business  units,  the
results were relatively unchanged.

During  the  quarter, the Company continued to strengthen and  reshape  its
management team by adding members with proven telecom and software  product
experience.   At  the same time, it also took steps to  improve  sales  and
marketing  processes, to streamline the contracts and bidding process,  and
to  strengthen  those teams with key hires specifically  from  the  telecom
industry.

"TCSI's   goal  is  to  offer  value-priced  solutions  using  customizable
products.  This enables our customers to reduce time-to-market and cost  of
ownership  of  their products and services," said Ram Banin, president  and
chief  executive officer of TCSI. "In order to achieve this  goal,  we  are
continuing  our investment in SolutionCore TM, TCSI's middleware platform for
telecom operation support systems (OSSs).  We believe that SolutionCore  is
the   most  advanced,  widely  deployed  middleware  platform  for  telecom
applications   and   we  want  to  maintain  that  competitive   advantage.
Additionally,  we  are  expanding  our  product  portfolio  by  adding  new
applications  to  SolutionSuites TM, our configurable, turnkey  systems. This
approach offers our customers lower cost alternatives to custom development
and  enables TCSI to expand its marketing reach to incumbent,  as  well  as
emerging telecom service providers."
