STM-1/OC-3 Terminal Multiplexer

RAD's FCD-155 STM-1/OC-3 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 or 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 48.384 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 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.

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.
