DSET Ships ezAccess 3.4

Electronic Bonding Gateway Supports New Industry Standards and Further Improves Efficiency in Sending Access Service Requests

SHREWSBURY, N.J., August 27, 2002-DSET Corp., (NASDAQ: DSET) one of the industry's premier source of electronic bonding gateways and OSS solutions for global, multi-vendor networks, announced today the general availability of ezAccess 3.4, the latest release of this electronic bonding gateway.

ezAccess enables telecommunications providers to send and receive access service requests (ASRs) with trading partners when ordering bandwidth needed to provision special access/transport and switched access services.

ezAccess 3.4 supports the newly released Access Service Ordering Guidelines (ASOG) 25, released August 5. This new version now supports both ASOG 24 and 25 to allow customers an easy transition during their product upgrade. The product also supports connectivity to MetaSolv's Telecom Business Solution (TBS) 5.1.2.

ezAccess 3.4 can be deployed either as a stand-alone system or integrated with an order management system.

The latest version of ezAccess enables providers to automatically generate confirmation receipts for the transaction. These new enhancements further streamline the operations of providers that include competitive local exchange carriers (CLECs), incumbent local exchange carriers (ILECs), data local exchange carriers (DLECs), carriers that offer wholesale transmission facilities to other providers, and interexchange carriers (IXCs).

The ASR order process can be complex, requiring many of the 25 ASOG forms defined for this purpose. Some ASR orders can require more than 50 pages if sent by fax. DSET's ezAccess gateway automates this process. It can automatically generate the necessary forms and provide an economical and faster alternative to exchanging ASR data via fax or e-mail. Automating ASR orders minimizes errors that can delay transactions and be expensive to resolve.

"This latest release of ezAccess illustrates our firm commitment to provide our customers with not only the latest industry standards, but improved functionality, as well," said Jeff Gill, vice president of Professional Services, at DSET. "Customers can now quickly satisfy all ASOG 25 requirements to keep up with the intensely competitive telecom marketplace."
