1-4 Physical Description FCD-E1LC Ver. 1.0
• FCD-E1LC units with the optional sublink can be used to interconnect other
equipment with fractional E1 interface (for example, a local digital PBX
equipped with an E1 trunk can be connected to the PBX at the main office)
• The FCD-E1LC also provides Layer 2 (Ethernet bridge) services between a
remote LAN, for example, at a branch office, and the main office LAN. The
user can configure the FCD-E1LC to operate either as a LAN
extender/repeater that transparently transfers all the traffic on the local LAN
to the remote LAN, or as a remote bridge that filters the LAN traffic and
blocks traffic addressed to local stations. The FCD-E1LC bridge supports
VLANs and quality-of-service features.
The user can select the main link bandwidth allocated to each type of traffic in
accordance with the desired throughput.

compact standalone unit, intended for installation on desktops or shelves. Unit
height is only 1U (1.75"). An optional rack-mount adapter kit enables the
installation of one or two FCD-E1LC units (side by side) in a 19-inch rack.
FCD-E1LC is cooled by free air convection, and does not include internal fans. The
FCD-E1LC front panel includes only indicators that indicate its status.
