The OPCOM3500E-120FE×8L-GE is a tributary service card used by the iTN2100.
Support accessing 8-way optical signals. Each-way signals support up to 4-way E1
services and 1-way 100 Mbit/s Ethernet services.
Map up to 32-way E1 services to SDH signals at the card and then aggregate them
through the aggregation card. Aggregate up to 8-way 100 Mbit/s Ethernet services into
1-way GE services at the card and then output them through the GE interface on the
front panel or transmitted to the switching card through the backplane.
Provide 8 multiplexing optical interfaces and 1 GE interface.
Support complete alarm indication feature. Local alarms and remote alarms are
displayed simultaneously.
