Fact Sheet For Bell Atlantic Long Distance Data Network

Network Elements and Vendors:

ATM - vendor still to be named.
-- ATM will provide communications fabric to drive scale economies and deliver quality of service capabilities over backbone network.

SONET/WDM Transport - Lucent Technologies
-- SONET provides highly resilient transmission capability. Use of WDM (wave
division multiplexing) will enable capacity expansion to keep pace with demand growth.

Internet Protocol Packet Router - vendor still to be named.
-- Router will collect, transport and manage IP-based services and applications.

Digital Voice Switch (5ESS*) - Lucent Technologies
-- Switch will collect circuit-switched voice signals for translation into ATM-based data
packets. Also will provide full interconnection with national voice signaling network.

Systems - Lucent Technologies - will ensure software systems interoperate
1) Operations - provides functions such as ability to monitor traffic flow over network.
2) Administration - provides database capabilities, such as inventory of circuit
assignments.
3) Maintenance - provides functions such as ability to spot and correct network
problems before they affect customers.
4) Provisioning - provides functions such as ability to assign circuits to customers.

Network Architecture:

SONET Rings
-- self-healing, high capacity.

Interconnection with other networks
-- will have "peering" and other interconnection relationships at appropriate locations.

Initial four hubs:
1) Boston
2) New York
3) Philadelphia
4) Washington, D.C. area (Arlington, Va.)

Timeline for Deployment of Services:

Phase I
-- Deploy basic ATM/SONET network to support services such as Internet backbone
transmission and voice -- 1Q/99 (contingent on appropriate regulatory relief)

Phase II
-- Expand hubs to additional cities to deploy services -- 2Q/99 (contingent on
regulatory relief)

Phase III
-- Add voice and data service enhancements -- 3Q/99 (contingent on regulatory relief)
