The Ciena/World Wide Packets Service Concentration Switch (SCS) and Service Delivery Switch
(SDS) family of products provide Ethernet connectivity to buildings and residences for the
purpose of delivering high-speed voice, video, and data connectivity. Both SCS and SDS devices
are designed to lower the overall cost of building out a fiber network.
The LE-4xx SCS includes 16 10/100 Mbps RJ-45 Ethernet ports for subscriber connections. It also
provides 2 dual speed 100BASE-FX/1000BASE-X SFP uplink ports. A 10/100 Mbps RJ-45 and DB-9
RS-232 port are provided for local management.
All models of LE-4xx SCS devices provide one 10/100 Mbps port for local management. These
models also provide uplink services using four 1000BASE-X, small form factor pluggable (SFP),
and single mode fiber Ethernet links.
The LE-4xx SCS delivers services using 16 1000 Mbps small form factor pluggable (SFP) Ethernet
ports and a 10/100 Mbps local management port. Although any number of configurations are
possible, typically one to four of the Gigabit ports are configured as upstream ports.
