The FCD-155 terminal multiplexer delivers next-
generation Ethernet services as well as
traditional traffic over 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/T3
services.
Improves bandwidth efficiency
The FCD-155 connects LAN traffic over 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
48.384 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 next-generation Ethernet services
delivery over voice-oriented networks.
Multiservice offering
In addition to transporting next-generation IP
services, the FCD-155 continues to support E1/
T1 or E3/T3. The E1/T1 or E3/T3 traffic 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/
SONET infrastructures. It thereby enables
carriers and service providers to reduce both
OpEx and CapEx, as they leverage optical
bandwidth for revenue-generating , high
bandwidth Ethernet 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 48.384 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.
