Multiplexors FMUX-4E1, FMUX-8E1 and FMUX-16E1 transmit 4/8/16 E1 channels respectively
over the fiber optic link.
All channels have independent sync signals with their own frequencies.
There are 5-channel and 18-channel versions for transmission of four E1 channels and one/two digital port channel
(Ethernet 10/100Base-T and/or V.35/RS-530/RS-232/X.21).
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 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.
