KPMG Consulting to Feature DSET
E-Commerce Solutions
In Digital Broadband Solutions Centers

Bridgewater, NJ - April 3, 2000 - (NASDAQ: DSET) - DSET Corporation, a leading supplier of business-to-business e-commerce connectivity solutions for the telecom industry, today announced that KPMG Consulting, LLC, a leading provider of Internet integration services, will offer DSET's software products. These products were selected by KPMG Consulting and will now be available for interactive demonstrations to potential customers at KPMG Consulting's Digital Broadband Solutions Centers nationwide. The DSET products selected by KPMG Consulting include the ezLocal ordering gateway, which can be used by competitive telecom service providers to facilitate service offerings that range from conventional voice to digital subscriber line (DSL) and other high-speed services.

"Our experience building and testing CLEC-ILEC interconnection made it clear that new telecom service providers needed a very rapid implementation approach to bring their new product offerings to market," said Ray Sears, Senior Vice President, KPMG Consulting. "Integrating the DSET gateway into our COTS based standalone and Configure to Fit architecture solutions allows KPMG Consulting to bring a CLEC from zero to product launch in a quick, efficient, and cost-effective way."

"We're very pleased that KPMG Consulting has chosen to include our solutions in its telecom architecture," said Bill McHale, president and chief executive officer of DSET. "Although it's been little more than a year since we introduced our ezLocal gateway, DSET has become the premier supplier of pre-order, ordering, and post-order solutions for the competitive telecom market. We're interconnecting facilities-based carriers with trading partners in virtually every part of the country, and our products now support UNE-P operation to address the needs of an even larger market segment. We look forward to an evolving relationship with KPMG Consulting that will give people in the industry a 'hands-on' introduction to DSET's expanding product line."
