Commission File No.333-65898 [GRAPHIC OMITTED] PRESS RELEASE - ------------------------------------------------------------------------------- DSET Shipping New ASR Gateway Supports ASOG 23 and 24 - ------------------------------------------------------------------------------- Bridgewater, NJ - January 23, 2002 - (Nasdaq: DSET) - The latest version of the ezAccess gateway now being shipped by DSET Corporation gives telecom providers greater flexibility and ease of implementation for electronic processing of access service requests (ASRs). Service providers must exchange ASRs to order and subsequently provision network facilities such as high-speed data links. Many larger providers that offer to lease high-capacity facilities require electronic submission of ASRs instead of by fax or e-mail, making ezAccess capabilities especially important for competitive service providers. The full send and receive capabilities of ezAccess automate the ASR process for incumbent local exchange carriers (ILECs), interexchange carriers (IXCs), competitive local exchange carriers (CLECs), and carriers that wholesale transmission facilities to other providers. The latest version of ezAccess features compliance with industry-standard Access Service Ordering Guidelines ASOG 23 and ASOG 24. The ezAccess gateway's CORBA IDL interface has also been enhanced to facilitate integration with the MetaSolv Solution(TM), which automates ordering and other key communications management processes. With ASOG 23, ezAccess can be deployed in combination with MetaSolv Solution 4.3 and with MetaSolv 4.5 for both ASOG 23 and 24. "Since the implementation of DSET's first production gateway in 1998, our goal has been to ensure that our products are aligned with the operational requirements of current and potential customers," said Jeff Gill, DSET's vice president, professional services. "Our product-development and customer-engineering teams continue to fulfill this goal today. Our success in this effort is demonstrated by the significant features delivered in this ASR release as well as in the two prior releases we shipped in the last nine months." 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.
