                   New DSET LSR Ordering Gateway Now Available

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

Bridgewater, NJ - January 30, 2002 - (Nasdaq: DSET) - DSET Corporation today
announced a new version of its ezLocal ordering gateway. ezLocal is the
electronic-bonding software most widely used by U.S. competitive telecom
providers to submit local service requests (LSRs) to trading partners such as
the former Regional Bell Operating Companies (RBOCs) to order local loops and
related services, including 411 directory service.

The current version of ezLocal has been enhanced to support services and
features as defined in the industry-standard Local Service Ordering Guidelines
(LSOG) 4 and 5. In addition to LSOG 5 support, ezLocal now provides additional
responses in LSOG 4 when integrated with the MetaSolv Solution(TM)
communications-management system. ezLocal will also generate loss-notification
e-mails when the gateway receives related messages from trading partners about
orders that cannot be completed.

"It's not an exaggeration to say that DSET's ezLocal gateway has been integral
to the success of dozens of competitive telecom providers that are winning and
keeping customers in a very tough marketplace," said Jeff Gill, DSET's vice
president, professional services. "We were the first to give competitive
providers an automated off-the-shelf alternative to ordering local lines via
paper faxes and e-mail, and our continuing product-development efforts keep
ezLocal ahead of any competing product. We're the leader when it comes to OSS
interconnection technology, and we're determined to maintain this position with
the products and services that the industry needs."

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
