        TCSI CORPORATION REPORTS SECOND QUARTER RESULTS

ALAMEDA, California - July 16, 1997 - TCSI Corporation (Nasdaq: TCSI), a
global provider of software to the telecom industry, today announced
revenues of $9.5 million for the second quarter ended June 30, 1997.  For
the same period last year, revenues were $21.8 million including $8.5
million from discontinued non-telecom business units.  The Company also
reported a net loss of $0.9 million for the second quarter of 1997,
compared to net income of $2.8 million for the same period in 1996.  The
second quarter 1997 loss per share was $0.04, compared to earnings per
share of $0.13 last year. The second quarter 1997 loss includes a non-
recurring charge of $0.8 million, or the equivalent of approximately $0.03
per share, resulting from an adjustment to the market-value of equipment
held for resale due to the termination of a non-telecom contract in the
third quarter of last year.

"We've made progress this year with new relationships secured through
channels, on projects with our existing customers, and on achieving our
operating goals.  There continues to be a worldwide need in the telecom
industry for faster delivery cycles and more automated processes at reduced
operating costs.  I continue to believe that TCSI is well positioned to
meet these needs by leveraging our industry expertise to build components-
based solutions using our standards-compliant middleware platform," said
Ram Banin, president and chief executive officer.

Services margins were 43 percent for the second quarter of 1997, compared
to 47 percent a year ago, improved from 34 percent in the first quarter of
1997.  In the second quarter of 1997, the Company spent nearly $1.4 million
or 14 percent of revenues on development of its software products,
primarily SolutionCore TM.  For the remainder of the year, the Company
expects to continue its product development spending in SolutionCore as
well as SolutionSuites TM.  Selling, general, and administrative expenses for
the quarter decreased 27 percent, compared to the same period last year,
primarily as a result of facilities consolidation and improved staffing
efficiencies.
