This convertor provide conversion from ITU-T G.703 E1 channel to 4 Ethernet interface.

PRODUCT CHARACTER
(1)Based on selfcopyright IC. (2)4 switch 10M/100M Ethernet,Semi/full duplex self adapt, support VLAN. (3)RJ45 interface support auto-mdix. (4)Provide 2 clock types: E1 master clock, E1 line clock. (5)provide 3 loop functions: local loop, to remote loop, order remote loop. (6) support 2 impedances: 75 Ohm unbalance and 120 Ohm balance. (7)Have Ethernet monitor self-reset function, equipment will not dead. (8)provide detecting realtime Ethernet communication status. (9)support 1-4 Ethernet switch function. (10)Network manager use SNMP. (11)Two types:Standalone, desktop, 19inch;Card,usually be inserted in our rack 19 inch.
