Ethernet over SDH or SONET Terminal Multiplexer

RAD's FCD-155 Ethernet over SDH/SONET terminal multiplexer transports Ethernet traffic over SDH or SONET networks, enabling carriers and service providers to launch next-generation services while continuing to support E1, T1, E3 and T3 traffic.

Installed at the customer site, the FCD-155 Ethernet over SDH or SONET terminal multiplexer supports generic framing procedure (GFP) and virtual concatenation, enabling IP channel bandwidth configuration in increments of 2 Mbps (VC-12), 1.5 Mbps (VT 1.5) or 50 Mbps (VC-3 or STS-1) at up to 100 Mbps wire-speed.

The FCD-155 is widely deployed by carriers and service providers to leverage their optical bandwidth for revenue-generating Ethernet services, while enterprises, utilities and campuses use the FCD-155 to provide LAN services over existing fiber optic infrastructures.

By using the FCD-155, both service providers and customers benefit from better bandwidth utilization, service granularity and a larger selection of services.

• Provides revenue-generating Ethernet services while preserving investment in legacy STM-1/OC-3 networks

• Optimizes bandwidth utilization over existing STM-1/OC-3 networks

• Expands Ethernet service offerings of carriers and service providers

The FCD-155 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.

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.

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.
