DSET Announces New Gateway Product and Web-Based Service Offering

ezConnector Integrates ezPreOrder and ezLocal
Gateway Products and ezSupport Provides Web-Based Customer Support

LAS VEGAS, TMW, Oct. 29, 2002—DSET Corp., (NASDAQ: DSET) one of the industry’s premier sources of electronic bonding gateways and Operations Support System (OSS) solutions for global, multi-vendor networks and telecommunications providers announced today ezConnector, a new gateway product enabling competitive local exchange providers (CLEC) to streamline the processing of orders with trading partners and improve customer satisfaction. DSET also introduced ezSupport, a new web-based customer support system that accelerates the delivery of support services to customers.

ezConnector will be demonstrated at DSET’s Booth # 611 at TeleManagement World conference and exhibition held October 28 through October 31, 2002 at the Mirage Events Center in Las Vegas.

ezConnector integrates DSET’s ezPreOrder and ezLocal electronic bonding gateway products in the standalone graphical user interface (GUI). This latest leading edge gateway solution automates the process of obtaining pre-order information from the Customer Service Record (CSR) through the latest version of DSET’s ezPreOrder application, and automatically posts that information directly on to the local service request (LSR) order in the updated version of the company’s ezLocal gateway application. ezConnector eliminates the time-consuming manual steps of retrieving and re-entering data from the CSR helping to reduce overhead expenses and minimize errors that can delay transactions and lower customer satisfaction.

ezSupport, a secure, password-protected web portal, allows customers to access technical documentation, new releases of products, as well as software patches and fixes, from the Internet. ezSupport can be accessed using a standard web browser. Troubleshooting functionality is scheduled to be included in the next release of ezSupport.

"The new product and service illustrate our commitment to continuously deliver innovative solutions that meet industry standards and the needs of providers," said Binay Sugla, Ph.D., president and CEO of DSET. "DSET’s goal is to provide products and services so CLECS can compete more effectively and improve their bottom line."

ezConnector will be available in mid-December under DSET’s ezRental Program. ezSupport is currently available and is free to all customers with current maintenance contracts.
