E1/T1 Ethernet Multiplexor

Fast Ethernet fibre multiplexer card
4 channels unframed E1/T1 (transparent) (FRM220-FOM04)
1 channels unframed E1/T1 (transparent) (FRM220-FOM01)
Can be configured to enable or disable the port, reset the port, and provide local or remote diagnostic loopback
Remote, fibre connected standalone card, can also be managed through in-band management via the chassis NMC
SFP modules can be chosen to support single-mode, multimode, single fibre bi-directional or Coarse and Dense Wave Division Multiplexing (CWDM and DWDM)
Supports link fault Pass-Through for Ethernet
One clear channel RS232 up to 250Kbps(Async) (FRM220-FOM04)
1+1 fibre protection, switching time < 50ms (FRM220-FOM04)
AIS on signal loss on E1/T1 and fiber port (FRM220-FOM04)
Loopback test on E1/T1, RS232, fiber ports (FRM220-FOM04)
Supports Order wire Ear / Microphone port (FRM220-FOM04)
