DSET Ships New ASR Gateway; Available Under New Low-Cost Rental Plan.

Business/High Tech Editors

BRIDGEWATER, N.J.--(BUSINESS WIRE)--Oct. 10, 2001

DSET Corporation (Nasdaq:DSET) has announced a new version of the ezAccess gateway used to automate the processing of access service requests (ASRs) telecom service providers must exchange to order and provision special services such as T-1 lines.

Many larger providers that offer these network facilities for lease require that orders be submitted electronically instead of by fax or e-mail, making ezAccess capabilities especially important for competitive service providers.

ezAccess is available to all service providers in the United States under DSET's new rental plan for a monthly cost that can be as low as $3,867. The plan has a 90-day cancellation clause and includes technical support, software upgrades, and change-management services. Detailed information about this new rental plan can be obtained by sending e-mail to [e-mail].

The full send and receive capabilities now available with ezAccess can automate the ASR process for any type of telecom provider, including 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 also allows a service provider to use the gateway as a fully bi-directional stand-alone system, as well as giving providers the option of deploying it in combination with the order management system (OMS) offered by a major DSET software partner. Additionally, ezAccess has a CORBA IDL interface that facilitates integration of ezAccess with virtually any OMS that a service provider may want to deploy.

"With over 30 communications providers using our gateways across the country, DSET has more products in real-world use than any other supplier," said Bill McHale, DSET's president, chief executive officer, and chairman of the board. "That's an unmatched vote of confidence in DSET technology and DSET service.

"Over the past nine months, we've shipped three new versions of ezAccess, and more than eight new versions of other products in our gateway suite. However, we also recognize that these are very difficult times for the telecom industry, especially for CSPs. That's why we've launched our gateway rental plan as a mutually beneficial way to place more of our gateways in production environments in a way that allows providers to avoid large capital expenditures. It's clearly a win-win plan."

In addition to ezAccess, all other DSET gateways are available under the company's rental plan to service providers in the United States, whether they are using a competitor's software or not. Current DSET customers in the United States may obtain additional gateways by taking advantage of this plan.

The other gateways offered by DSET cover a broad spectrum of electronic-bonding requirements for the telecom industry:

-- ezPreOrder for automating the retrieval of accurate and up-to-date customer
information from RBOCs

-- ezLocal for ordering local loops and other services from RBOCs

-- ezTroubleAdmin to automate the resolution of service outages caused by
problems in RBOCs' networks

-- ezNumberPort to interconnect with the eight Number Portability
Administration Centers (NPACs) in North America to ensure that customers retain
their current phone numbers if they change service providers

-- ez911 to interconnect with the service bureau (Intrado Inc.) that helps to
provide enhanced 911 service throughout the United States

-- ezCallingCard and ezCallerID to interconnect with the service bureau
(Illuminet) that facilitates these services for competitive providers
