The Alcatel 1660 SM, which is part of the company’s next-generation SDH, data-aware Optical Multi-Service Node (OMSN) family, interworks with other Alcatel products for metro edge and core applications. The 1660 SM is an add/drop multiplexer and small crossconnect. Designed to scale in step with service demands, the upgraded Alcatel 1660 SM provides transport and integrated networking functions for data applications, including metro Ethernet and storage area networks (SANs). The company believes that support of CWDM functionality, together with the multi-protocol aggregation capabilities of its “4xAny” service concentrator (which enables the grooming of multiple services — including Gigabit Ethernet, Fiber Channel, and ESCON/FICON — into a single SDH or SONET standard signal), positions the 1660 SM to efficiently interconnect enterprise data centers in SAN extension applications. The integration of the Integrated Service Adapter (ISA) Packet Ring plug-in card enables operators to complement their metro Ethernet service offering, according to Alcatel.
