4 port E1 to Ethernet converter, E1 port support *5ohm or **0ohm, Ethernet port support *0/**0M bps. LAN-WAN connectivity Realize transparent transfer Ethernet data in 1 to 4 E1 channels *0M/**0M Ethernet, full/half duplex self adapt, support VLAN. Ethernet support AUTO-MDIX( cross over and straight through self adapt) setting CRC alarm limitation to auto isolate lines with low transfer quality, single direction. When one direction error rate over limitation, disconnect only one direction, the other is not affected. Unbalance in two directions. Allow 4 E1 channels up to *0ms transfer delay. when the delay over the limitation, can stop transfer automatically. Having 2 loop back functions: E1 local loop, E1 external loop. Support Dynamic Ethernet MAC address(***6), having local address filter function. E1 interface compatible with ITU-T G.**3, G.**4, and G.**3. signaling slot not supported. E1 interface having internal clock resume circuit and HDB3 codec circuit. support E1 channel hot plug, and auto detect available E1 channels not pause the transmission. supporting 1 to 4 E1 channels customized configuration, auto detect the number of E1 channels and select the available E1 at reset. E1 Support *5ohm/unbalance impedance or **0ohm/balance for option support reset remote system from local system. having Ethernet monitor auto reset function Parameter and specifications E1 interface Standard: E1 interface compatible with G.**3 standard. Rate: 2.**8Mbit/są*0ppm Coding: HDB3 Impedance: *5ohm(unbalance) or **0ohm(balance) Connector: BNC(*5ohm) or RJ*5(**0ohm) Jitter Performance: According to G.**2 and G.**3 *0/**0Base-T Rate: *0M/**0M, full/half duplex self adapt.
