Bridgewater, NJ - October 30 - (Nasdaq: DSET) - DSET Corporation and Fathom Solutions, LLC, a consulting firm focused on the telecommunications industry, have signed an agreement under which Fathom will offer systems integration services to competitive telecom providers. DSET is a leading supplier of software solutions that enable competitive carriers to build a Trading Partner Network that automates the interconnection with other providers essential for turning on and maintaining services for customers.

As a DSET alliance partner, Fathom will build Trading Partner Networks for clients using DSET software solutions. Services to be provided by Fathom include general program management, installation and testing of DSET software, integration of DSET solutions with a client's order management system (OMS), and testing of the interfaces with the client's trading partners.

Fathom can also offer DSET clients services such as evaluating the overall efficiency of key technical and business processes in areas other than electronic bonding with trading partners. Fathom's experience in enhancing business operations and delivering telecom software solutions will help to cost-effectively expedite DSET customers' time-to-market objectives with the DSET family of solutions for automating essential sales, pre-order, order, and post-order functions. DSET solutions offer support for obtaining customer service records from trading partners, ordering local loops and high-capacity circuits, supporting E911 changes, calling-card and caller ID services, selecting long-distance providers, local number portability, and trouble-ticket administration.

"Fathom is dedicated to helping new telecom providers implement the best solutions possible to maximize the potential of their technical and human resources," said Jason Lee, vice president of Fathom Solutions. "This requires that we offer our clients the capabilities of partners that lead in their respective fields. When it comes to electronic bonding and trading-partner interconnection, DSET is definitely a leader."

"We live in a multi-solutions environment, where no single company can provide the total solution to the client," said John Scheifele, director of the DSET Alliance Program. "Our Alliance Program strives to identify 'best of class' partners with solutions that augment DSET's product offerings. This approach is clearly a 'triple win' proposition. The client receives the best overall solution available, DSET can focus on our core mission of delivering commercial off-the-shelf solutions, and our partners can do what they are best at, which is the integration of third-party products."
