Net2000 Expedites Local Ordering Process via Electronic Bonding with Bell Atlantic

CLEC a National Leader in Establishing Electronic Bonding for High Capacity T-1s; DSET Gateway Automates Local Ordering

Herndon, VA (March 16, 2000) Net2000 Communications, Inc. (Nasdaq: NTKK) is among the first to deploy electronic bonding with Bell Atlantic for the ordering and provisioning of high capacity bandwidth to connect customers to its network. DSET's ezConnect and ezAccess Gateways power the system.

"We are very pleased to be among the first CLECs in the nation to deploy this advanced platform, which will allow us to vastly improve the efficiency of provisioning high capacity, broadband connections to our customers - - each of whom averages four T-1s of bandwidth. This will vastly improve the accuracy and volume of orders that we can process each month," said Net2000 chief executive officer Charlie Thomas.

"We applaud Net2000 for investing in technologies that will speed the ordering process for its customers by enhancing the interface with our systems," said Pat Hanley, president of Bell Atlantic (NYSE: BEL) Wholesale Services. "We will continue to work closely with Net2000 and other carriers to improve the way we do business with each other."

Previously, the manual ordering process required faxing forms up to 30 pages in length, which was slow and introduced human error. The DSET gateways enable Bell Atlantic and Net2000 computers to automate the ordering process, thereby significantly reducing the time to process each order while eliminating errors and duplicative manual entry. This new process is much more efficient and will allow Net2000 to switch more customers to its local service offering each month.

Mark Mendes, Net2000's chief operating officer, stated, "We believe this is the first OSS to OSS gateway with Bell Atlantic for high capacity, T-1 connections. Other CLECs have achieved this for basic analog lines, but our electronic interface meets the unique needs of our customers who are larger and more sophisticated than those of other CLECs. Our relationships with DSET and Bell Atlantic enabled us to install the gateway in record time, allowing seamless integration between our backoffice systems and enhancing our scalability."

"We are delighted that Net2000 has been able to turn up service and be certified throughout all Bell Atlantic regions using our ezAccess electronic-bonding gateway," said Phil Cavallo, DSET's senior vice president of worldwide sales and marketing. "This is the first production implementation of the DSET ezAccess ASR Gateway with Bell Atlantic. Net2000 has purchased a suite of DSET gateways to automate key business processes including E911 and Caller ID information. Integrated with MetaSolv's (Nasdaq: MSLV) Telecom Business Solution TM (TBS TM) software, our ezAccess Gateway enables Net2000 to streamline the ordering process for its customers."
