FCD-155E
Ethernet and E1/T1, E3/T3 SDH/SONET ADM
The FCD-155E SDH/SONET add and drop
multiplexer delivers next-generation Ethernet
services as well as E1/T1 and E3/T3 traffic over
SDH/SONET networks. Installed at the customer
site or directly on STM-1/OC-3 access rings, the
FCD-155E leverages the SDH/SONET
infrastructure for Internet access and LAN
connectivity, while providing continued support
for E1/T1 and E3/T3 services.
Improves bandwidth efficiency
The FCD-155E connects LAN traffic by creating
an SDH/SONET network. 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
SDH/SONET infrastructure for LAN connectivity.
FCD-155E 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.
Multiservice offering
In addition to transporting next-generation IP
services, the FCD-155E continues to support
E1/T1 and E3/T3 services. The traffic is mapped
into the SDH/SONET frame and can be
terminated at any point on the network.
Reduces costs, increases revenues
The FCD-155E acts as a LAN and E1/T1 or E3/T3
terminal as well as an STM-1/OC-3 ADM.
Incorporating these functions in a single device
reduces the number of units needed and lowers
implementation costs.
The FCD-155E brings Ethernet economics and
packet switching efficiency to SDH/SONET
infrastructure. It thereby enables carriers and
service providers, as well as private fiber
network owners such as utilities and campuses,
to reduce both OpEx and CapEx as they use
their optical bandwidth for revenue-generating
Ethernet services. For a modest investment,
SDH/SONET carriers can tap into new business
opportunities while leveraging their existing
equipment to support clear channel data
streams and the latest high bandwidth services.
Service providers addressing enterprise
customers benefit from better utilization of
network bandwidth (for example, a user who
needs 10 Mbps LAN will require five VC-12 or
seven VT 1.5 links instead of a full 48.384 Mbps
VC-3 or STS-1 connection), and have 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.
