Multiplexors FMUX/S-4E1/ETM and FMUX/S-16E1/ETM transmit 4 and 16 E1 channels respectively over one fiber and Ethernet 10/100Base-T channel with 100 Mbps bandwidth over another fiber of two-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 dedicated Ethernet 10Base-T port ("-SNMP" option 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.
