FMUX/SAT is a variable frame structure multiplexor for transmitting up to 4 E1 channels over the synchronous link equipment with codirectional interface (e.g., satellite modem with V.35 DCE interface).

All E1 channels have independent sync signals with their own frequencies. Link speed depends on the number of Е1 channels transmitted:

No. of Е1 channels	Link speed, Mbps
4	8.448
3	6.336
2	4.224
1	2.112

Internal loopbacks and integral BER tester operation are controllable by the console port located on front panel. BER tester meters bit error rate in 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 link.

FMUX/SAT has LEDs for channels ready state, link equipment operability, loopbacks enable state and test mode indication.

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.
