DSET Announces ASR Receive Gateway

Automatic Receive Capability Speeds Provisioning of Services for More Telecom Providers

Bridgewater, NJ - February 8, 2001 - (Nasdaq: DSET) - DSET Corporation announced today that a new version of its ezAccess ASR gateway will be shipped at the end of the first quarter of 2001. ezAccess 3.0 offers enhancements that extend the gateway's utility to a more diverse group of telecom service providers, including competitive local exchange carriers (CLECs), incumbent local exchange carriers (ILECs), data local exchange carriers (DLECs), carriers that wholesale transmission facilities to other providers, and interexchange carriers (IXCs).

DSET's ezAccess 3.0 introduces an even greater degree of efficiency and economy by making it possible for a service provider to receive access service requests (ASRs) automatically, when deployed in combination with the order management system offered by a major DSET software partner. By providing full bi-directional automation compliant with current industry-standard Access Service Ordering Guidelines, ASOG 22, ezAccess 3.0 streamlines the process of requesting bandwidth needed to provision special access/transport and switched access services.

Previous versions of the ezAccess gateway eliminated the highly manual procedure of sending ASR forms to trading partners via faxes or e-mail. In addition to providing the ability to receive ASRs, ezAccess 3.0 also eliminates the manual processing of e-mail responses to trading partners related to the receipt of an ASR. These responses can include firm order confirmations, clarifications, requests, error notifications, and design layout reports.

"Our ASR solution always had the ability to 'send' orders. We can now help service providers who need to 'receive' orders electronically," said Vera Helen Clements, DSET's ezAccess product manager. "As a service provider's volume of ASRs increases, their trading partners will become more and more reluctant to process orders manually, creating an operations challenge that demands an automated bi-directional solution. We are pleased to announce that ezAccess 3.0 meets this challenge with capabilities and efficiency essential for the continued success of many competitive carriers."
