                          DSET Shipping New ASR Gateway

                            Supports ASOG 23 and 24

- -------------------------------------------------------------------------------


Bridgewater, NJ - January 23, 2002 - (Nasdaq: DSET) - The latest version of the
ezAccess gateway now being shipped by DSET Corporation gives telecom providers
greater flexibility and ease of implementation for electronic processing of
access service requests (ASRs). Service providers must exchange ASRs to order
and subsequently provision network facilities such as high-speed data links.

Many larger providers that offer to lease high-capacity facilities require
electronic submission of ASRs instead of by fax or e-mail, making ezAccess
capabilities especially important for competitive service providers. The full
send and receive capabilities of ezAccess automate the ASR process for incumbent
local exchange carriers (ILECs), interexchange carriers (IXCs), competitive
local exchange carriers (CLECs), and carriers that wholesale transmission
facilities to other providers.

The latest version of ezAccess features compliance with industry-standard Access
Service Ordering Guidelines ASOG 23 and ASOG 24. The ezAccess gateway's CORBA
IDL interface has also been enhanced to facilitate integration with the MetaSolv
Solution(TM), which automates ordering and other key communications management
processes. With ASOG 23, ezAccess can be deployed in combination with MetaSolv
Solution 4.3 and with MetaSolv 4.5 for both ASOG 23 and 24.

"Since the implementation of DSET's first production gateway in 1998, our goal
has been to ensure that our products are aligned with the operational
requirements of current and potential customers," said Jeff Gill, DSET's vice
president, professional services. "Our product-development and
customer-engineering teams continue to fulfill this goal today. Our success in
this effort is demonstrated by the significant features delivered in this ASR
release as well as in the two prior releases we shipped in the last nine
months."

In recognition of the telecom industry's challenging fiscal environment, DSET
continues to offer the broadest suite of interconnection gateways to its
existing 31 production customers as well as to other interested service
providers in the United States under three distinct pricing models: a perpetual
license, a monthly rental program and/or a hosted





implementation via BizTelOne's clearinghouse. Detailed information about DSET's
gateway offerings can be obtained by sending e-mail to info@dset.com.
