Multiplexer
  • 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)
