                 CATAPULT COMMUNICATIONS REPORTS RECORD REVENUES
                     FOR SECOND QUARTER OF FISCAL YEAR 2003

Mountain View, CA--APRIL 17, 2003--Catapult Communications Corporation (Nasdaq:
CATT) reported today record quarterly revenues for its second fiscal quarter
ended March 31, 2003. Total revenues for the quarter were $14 million, a 16
percent increase over revenues of $12.1 million reported in the second quarter
of fiscal year 2002. Almost 60 percent of the quarter's revenues were generated
in Japan, where Japanese fiscal year end sales were unexpectedly high.

Net income for the second fiscal quarter was $1.7 million or $0.13 per diluted
share. This compares to net income of $3.7 million or $0.28 per diluted share in
the second fiscal quarter of 2002. Results for the second quarter of 2003
include revenues and expenses of the network diagnostics business (NDB) acquired
from Tekelec last August.

During the second quarter of fiscal year 2003, for the first time, Catapult
repurchased 257,400 shares at a cost of $1.8 million under its previously
authorized stock repurchase program.

BUSINESS OUTLOOK

"As I indicated last quarter, we continue to see evidence that the worst may be
over for the telecom industry," said Dr. Richard A. Karp, Catapult's Chairman
and CEO. "We are seeing some preliminary signs that customers in both Europe and
Japan are beginning development efforts for 4G digital cellular, with initial
requirements being mandated as soon as late summer. These will be small projects
at first, but they give us some confidence that telecom is starting to plan for
the future, instead of merely surviving the present.

"Although sales in Europe and North America were not what we expected in the
quarter just completed, sales activity continues to improve. We remain cautious,
however, until we see this activity turn into orders. As a result, we are
projecting revenues of $12 million for the third quarter of fiscal year 2003.
This would represent a 50% increase over the third quarter of fiscal 2002," Dr.
Karp concluded.
