The FCD-155 STM-1/OC-3 terminal multiplexer delivers next-generation Ethernet services as well as TDM traffic over existing SDH/SONET networks. Installed at the customer site, the FCD-155 leverages the SDH/SONET infrastructure for Internet access and LAN connectivity, while providing continued support for all E1, T1, E3 and T3 services.

Supports GFP or X.86 encapsulation

The FCD-155 connects LAN traffic over existing SDH/SONET networks. Support for generic framing procedure (GFP) or X.86 encapsulation with virtual concatenation enables configuring the bandwidth of the IP channel in increments of 2 Mbps (VC-12), 1.5 Mbps (VT 1.5) or 50 Mbps (VC-3 or STS-1), up to 100 Mbps wire speed, for cost-effective adaptation of the SDH/SONET infrastructure for LAN connectivity.

FCD-155 eliminates the rigid bandwidth restrictions usually imposed by SDH/SONET virtual containers, and allows for scalable and efficient delivery of next-generation Ethernet services over voice-oriented networks.

Next-generation IP and E1, T1, E3, T3 services

In addition to transporting next-generation IP services, the FCD-155 continues to support E1, T1, E3 or T3, which is mapped into the SDH/SONET frame and can be terminated at any point on the network.

Reduces costs, increases revenues

The FCD-155 brings Ethernet economics and packet switching efficiency to existing SDH or SONET networks. It thereby enables carriers and service providers to reduce both operating and capital expenditures, as they use their optical bandwidth for revenue-generating Ethernet services. For a modest investment, SDH/SONET carriers can exploit new business opportunities by leveraging their existing equipment to support clear channel data streams and the latest high bandwidth services.

A service provider serving enterprise customers benefits from better bandwidth utilization on the network (for example, a user who needs 10 Mbps LAN will use five VC-12 or seven VT 1.5 links instead of a full 50 Mbps VC-3 or STS-1 connection), and gains the ability to offer service granularity similar to next-generation Ethernet networks. End users benefit from lower costs and a larger selection of services that can better meet their specific connectivity requirements.
