E3-Multiplexor FMUX-16-E3 Features:
  • Transmittion of sixteen E1 channels via E3 link
  • Model with additional Ethernet 10/100Base-T and V.35/RS-530/RS-449/RS-232 channels
  • Compliance with ITU-T G.703, G.742, G.823, G.955 Recommendations
  • Local and remote loopbacks
  • Integrated BER tester
  • Console RS-232 port
  • Optional SNMP Ethernet control port
  • Remote management
  • Dry contacts alarm interface
  • Stand-alone or rack-mount 1U
  • AC or DC power
  • Certificate N OS-2-SP-1458 of Russian Ministry of Communications

FMUX-16E1-E3 is a multiplexor for transmitting 16 E1 channels over the E3 link or E3 link. All channels have independent sync signals with their own frequencies.

The device has optional channels (Ethernet 10/100Base-T and V.35/RS-530/RS-232/X.21). Optional channels are transferred instead of 1 to 4 E1 channels (console configurable).

Model with Ethernet 10/100Base-T port supports VLAN protocol.

FMUX has LEDs for channels ready state, loopbacks enable state and test mode indication. Internal loopbacks and integral BER tester operation are controllable by the console port located on front panel. BER tester meters bit error rate in E3 link using permanent or pseudo random code in compliance with the ITU-T O.151 Recommendation (test sequence length equals to 223-1=8388607 bits).

Device state can be monitored by SNMP using separate Ethernet 10Base-T port.

Remote device management is available by remote login feature. Service data exchange is supported by additional service channel using same E3 link.

Alarm indication relay with "dry contacts" interface in compliance with the ITU-T G.742 Recommendation, paragraph 10, is supplied.

The firmware of the device can be updated by user.

Currently available models are listed in Prices. Please, contact technical support if you are unsure which model to choose.
