NewSouth Communications To Deploy Five DSET Gateway Solutions

Bridgewater, NJ - August 15, 2000 - (Nasdaq: DSET) - DSET Corporation, a leading supplier of business-to-business e-commerce connectivity solutions for the telecom industry, announced today that NewSouth Communications has purchased a suite of DSET gateways to automate virtually every aspect of migrating customers to the integrated communications provider (ICP) based in Greenville, South Carolina. The DSET gateways will enable electronic bonding with NewSouth trading partners that currently include BellSouth, GTE, and Sprint.

NewSouth will deploy DSET solutions to facilitate ordering local loops as well as high-capacity circuits, and to support local number portability, 911 service, and calling card service for their growing customer base in the southern U.S. In addition, the company will install a DSET gateway to speed the resolution of trouble tickets requiring the exchange of information with trading partners. The DSET ordering solutions will be integrated with MetaSolv Software, Inc.'s (Nasdaq: MSLV) Telecom Business Solution™ (TBS™) order management and service fulfillment solution.

"The combination of DSET gateways and MetaSolv's TBS solution allow us to more efficiently exchange information and share network capabilities with our trading partners," said Michael LaFrance, president and chief executive officer for NewSouth. "The high demands of our fast-growing ICP require us to select providers with industry experience and a proven track record. The team at DSET has shown us they are dedicated to providing the best products and services available in the market."

"The DSET gateways selected by NewSouth, along with MetaSolv's TBS, will enable comprehensive flow-through processing capabilities," said Phil Cavallo, DSET's senior vice president of worldwide sales and marketing. "The fact that NewSouth is deploying DSET solutions across its nine-state operating region speaks highly of DSET's strength in turning up new competitive carriers with BellSouth as a trading partner. The combination of DSET and MetaSolv solutions has also become the choice of the majority of carriers looking to rapidly turn on service in new markets."
