                      DSET Announces New Pre-Order Gateway

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


Bridgewater, NJ - January 29, 2002 - (Nasdaq: DSET) - DSET Corporation today
announced that it is shipping the newest version of the ezPreOrder
electronic-bonding gateway. The new ezPreOrder gateway has been enhanced to keep
pace with the evolution of industry-standard Local Service Ordering Guidelines
(LSOG 4 and 5) and provide even greater efficiency for interconnecting
competitive providers and their trading partners.

By automating the initial phase of transitioning customers to competitive
providers from trading partners, ezPreOrder substantially reduces order
turn-around intervals and operational costs. For example, automatic validation
of customer information in orders dramatically cuts the number of orders
initially rejected by trading partners.

ezPreOrder automates functions such as the retrieval of customer service records
(CSRs) from incumbent carriers, address validation, telephone-number
reservation, and xDSL loop qualification. The new ezPreOrder gateway shipped by
DSET offers upgrades to improve the efficiency of interconnection with trading
partners that include Ameritech, BellSouth, Pacific Bell, Qwest, SBC, and
Verizon.

"The new version of ezPreOrder is another indication of how DSET is maintaining
a dynamic presence in the market for OSS interconnection gateways," said Jeff
Gill, DSET's vice president, professional services. "In the past six months
alone, we've delivered ezPreOrder enhancements in two major releases and more
than a dozen `point' releases. This clearly demonstrates our commitment to
product development, in this case to offering service providers the best
solution for establishing a positive relationship with prospective customers
from the time of their initial inquiry. Winning and keeping customers is a
matter of delivering the best possible service right from the start, and that's
what competitive providers can offer with ezPreOrder."

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
