4e1/eth Protocol Converter

These 4E1/ETH Protocol Converter provides conversion from 1 to 4 E1 channels to Ethernet interface. Support 1 to 4 E1 channels setting, it can detect the number of E1 channel and select available channel. It can reach 8.192 M bandwidth when 4E1 channels work simultaneity. Transmit Ethernet signal (RJ45) via point-to-point to remote RJ45 interface, realize connection between E1 channel and Ethernet, and compose bridge. Can satisfy real-time video, audio, and data transmit.

Features
1,Realize transparent transfer Ethernet data in 1 to 4 E1 channels
2,10/100M Ethernet, full/half duplex self adapt, support VLAN
3,Ethernet support AUTO-MDIX (cross over and straight through self adapt)
4,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
5,Allow 4 E1 channels up to 10ms transfer delay. When the delay exceeds the limitation, device can stop data transfer automatically.
6,Have 2 loop back functions: E1 local loop, E1 external loop.
7,Support Dynamic Ethernet MAC address (4096), having local address filter function.
8,E1 interface compatible with ITU-T G.703, and without G.823 signaling slot
9,E1 interface has internal clock resume circuit and HDB3 codec circuit
10,support E1 channel hot plug, and auto detect available E1 channels not pause the transmission.
