- Lucent's Metropolis product family includes the DMX Access Multiplexer for central office and large enterprise applications, the DMXpress for customer premises applications, and a new DMXtend box for enterprise and loop access applications. All three systems provide metro Ethernet over SONET (EoS) using Generic Framing Procedure (GFP) and Virtual Concatenation technology.
- In June 2003, Lucent announced a contract to supply its Metropolis DMX Access Multiplexer to BellSouth.
- In February 2002, AT&T announced the integration of Cisco Systems' ONS 15454 SONET Multiservice Platform and the Cisco Transport Manager as key elements of its nationwide optical network buildout. AT&T is using the Cisco ONS 15454 to provide multi-service aggregation of lower-rate customer traffic up to high-speed (OC-48 or OC-192) pipes for routing across the network. AT&T said it would also use CIENA's CoreDirector optical switch as another key elements in its new intelligent optical network. AT&T is using the CoreDirector to carry traffic at a variety of bit-rates, from 45 Mbps to 10 Gbps, for provisioning services via point-and-click capability at both ends of the circuit.
