Certificate N ОС-6-СП-1998

FMUX-8 is a multiplexor for transmitting of eight E1 channels over the fiber optic link. All channels have independent sync signals with their own frequencies.

FMUX has LEDs for channels ready state, optic 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. 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 2²³-1=8388607 bits).

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

Device state can be monitored by SNMP using separate Ethernet 10Base-T port (-SNMP option available for /S version must be ordered).

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.
