FMUX-4-ETV8 is a 5 channel multiplexor for transmitting 4 E1 channels and one Ethernet 10/100Base-T channel over the fiber optic link. All channels have independent sync signals with their own frequencies.

The Ethernet 10/100Base-T channel transmits independently of E1 channels and has a bandwidth of 8192 kbps. VLAN protocol supported.

FMUX has LEDs for channels ready state, optic transceiver operability, loopbacks enable state and test mode indication. The control of loopbacks states and of the integral BER tester is available by the console port located on front panel. BER tester meters bit error rate in optic 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 optic 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.
