FMUX 4E1 is a multiplexor for transmitting 4 E1 channels over the E2 link. All channels have independent sync signals with their own frequencies.

The device has optional channel (Ethernet 10/100Base-T or V.35/RS-530/RS-232/X.21). With this option box models have 3 E1 channels and one optional channel, rack mount models have 4 E1 channels and one optional channel (console configurable 4 E1 or 3 E1 + optional channel modes).

Models with Ethernet 10/100Base-T port with the "-ETV" order code support VLAN protocol.

FMUX has LEDs for channels ready state, E2 transceiver operability, loopbacks enable state and test mode indication. Internal loopbacks and integral BER tester operation are controllable by the console port located on front panel or by switches. BER tester meters bit error rate in E2 link using permanent or pseudo random code in compliance with the ITU-T O.151 Recommendation (test sequence length equals to 215-1=32767 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 E2 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.
