CapRock Communications Automates UNE-P Ordering with DSET Solution

Bridgewater, NJ - October 2, 2000 - (Nasdaq: DSET) - DSET Corporation announced today that CapRock Communications (Nasdaq: CPRK) is implementing DSET's ezLocal ordering gateway, automating UNE-P interconnection with Southwestern Bell. Dallas-based CapRock Communications is DSET's first U.S. competitive telecom provider to implement fully automated UNE-P order processing.

Short for "Unbundled Network Element-Platform," UNE-P is an operating mode that enables a CLEC to place orders with an incumbent carrier for all of the network elements (loop, switch port, transport, and more) needed to provide phone service for new customers without deploying their own switches. Carriers operating in this mode could achieve substantially higher margins and have lower capital expenses for switches and related equipment. This process allows CapRock to maximize the value proposition of resale while at the same time converting customers to facilities-based service as it continues to build out its own network.

CapRock has deployed the DSET ezLocal gateway in combination with MetaSolv Software, Inc.'s (Nasdaq: MSLV) Telecom Business Solution™ (TBS™) software, an order management and service fulfillment solution that integrates CapRock's business processes. These products have enabled CapRock to achieve highly efficient flow-through processing of all orders.

"Continued implementation of flow-through provisioning benefits CapRock customers, shareholders and employees alike," said Ken Monblatt, senior vice president and CIO at CapRock. "DSET's software provides us the ability to centralize all ILEC order flows, thus streamlining the order processing and provisioning intervals beyond what we have already experienced with process optimization. Status of all orders will ultimately reside in one system, enabling CapRock to more effectively manage ILEC Service Level Commitments and order completion. All of these benefits translate into efficiency and further reduce order handling time and costs."

"We are extremely pleased to be part of what CapRock has accomplished in terms of automating a critical business process," said Phil Cavallo, DSET's senior vice president of worldwide sales and marketing. "This is another example of how the integration of DSET gateways and MetaSolv's TBS software is making it possible for new service providers to successfully pursue a wide range of strategies in the telecom market, including UNE-P operation."
