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
1Realize transparent transfer Ethernet data in 1 to 4 E1 channels
210/100M Ethernet full/half duplex self adapt support VLAN
3Ethernet support AUTO-MDIX (cross over and straight through self adapt)
4Setting 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
5Allow 4 E1 channels up to 10ms transfer delay. When the delay exceeds the limitation device can stop data transfer automatically.
6Have 2 loop back functions: E1 local loop E1 external loop.
7Support Dynamic Ethernet MAC address (4096) having local address filter function.
8E1 interface compatible with ITU-T G.703 and without G.823 signaling slot
9E1 interface has internal clock resume circuit and HDB3 codec circuit
10support E1 channel hot plug and auto detect available E1 channels not pause the transmission.
