CSG SYSTEMS DENIES ALLEGATIONS IN "MERITLESS"
COMPLAINT FILED BY AT&T BROADBAND

ENGLEWOOD, COLO. (March 29, 2002)- CSG Systems (NASDAQ: CSGS) today strongly
denied the allegations in a complaint filed Thursday by AT&T Broadband seeking
to force CSG to provide AT&T with data CSG believes AT&T is not entitled to
under their agreement at this time.

	CSG is a leading supplier of customer care and billing systems and it
provides a variety of services to AT&T under a long-term contract.  AT&T uses
CSG's services to provide customer care and billing support for approximately
16 million subscribers.

	In a complaint filed Thursday in Arapahoe County District Court, AT&T
alleged that CSG was in breach of the agreement for failing to acquiesce to
AT&T's demand that CSG provide a particular type of data to AT&T by April 15.
AT&T is seeking this data in a "standard deconversion format" and acknowledged
in its complaint that it wants this type of data in order to "to have an
alternative vendor prepared to replace CSG."

	"AT&T's complaint is meritless and we are confident that all its claims
will be dismissed," said Joe Ruble, CSG's senior vice president of corporate
development and general counsel.  "CSG is in full compliance with its
obligations under its contract with AT&T and this lawsuit is merely AT&T's
latest attempt to bully CSG into renegotiating the contract," Ruble added.

	AT&T's complaint is meritless for many reasons, Ruble noted.  Among
others, CSG is required to provide this data to AT&T in the requested format
only upon termination or expiration of the parties' contract.

	"Given that our agreement is in full force and effect, this request by
AT&T is premature.  It appears as though AT&T is making plans to breach its
obligations to CSG and CSG will do everything necessary to defend the integrity
of its agreement with AT&T- an agreement under which CSG has fully and
faithfully performed since 1997."

	CSG intends to file a written response to AT&T's allegations.
