N*64k FE1 fiber modem G.703 / V.35 protocol converter

Overview: 

Transmit N*64k E1 signal via fiber, realize long distance data and voice signals transmission, used with FMO-V35 can extend data channel of ATM or DDN

Main features:

◆ Having two row of LEDs, upper row indicate local status, lower row indicate remote status and alarm status. 

◆ Based on self –opyright IC, high software content (kernel chip based on software)

◆ Realize take out specified time-slots to compose N*64k(N=1—32) data channel.

◆ Provide 3 loop functions: local loop(ANA), to remote loop(DIG), order remote loop(REM).

◆  Have pseudo random code test function, easy the installation and maintenance.

◆  Realize rate setting of remote equipment (in slave clock status) when local equipment is in master clock status.

◆ E1 fiber modem can be used with V.35 fiber modem by pair, saved 1 G.703/V.35 converter.

◆ Power supply option:

, DC-48V. The positive and negative terminal can be exchanged for DC-48V, easy for installation and maintenance.

◆ Network manager interface use SNMP.
