General information:
4E1-10/100BT serial interface converter uses back multiplexing technology, transfers 10M/100M Ethernet data by using multi E1 channels. Realize convert between 1 to 4 E1 channels and Ethernet interface. It can transmit signal of E1 channel to RJ45 interface point to point, realize the connection of E1 channel and Ethernet. It different from normal bridge , supporting 1 to 4 E1 channels customized configuration, auto detecting the number of E1 channels and use the available E1, allow some limiting transfer delay between different E1 channels. Single line speed is 1968Kbits/s, 4 channels can up to 7872Kbits/s. it can connect with Ethernet switch or hub when in 10/100Mbps full/half duplex mode, make use of mass E1 resource in telecommunication networks to expend the transfer distance and application field of Ethernet, is a suitable solution for broadband switch in of Ethernet. It can used in fields such as connecting LANs, connecting end offices, VOD, remote monitor, E1 interface of switches, etc.
Product characteristics:
Realize transparent transfer Ethernet data in 1 to 4 E1 channels.
10M/100M 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 10ms transfer delay. When the delay over the limitation, can stop transfer automatically.
Provide 2 loop functions: E1 local loop, E1 external loop.
Support Dynamic Ethernet MAC address (4096), having local address filter function.
E1 interface according with ITU-T G.703, G.704 and G.823, does not support the using of signaling time slot.
E1 interface have internal clock resume circuit and HDB3 codec circuit.
Support E1 channel hot plug, and auto detect available E1 channels. No pause the transmission.
Support 1 to 4 E1 channels customized configuration, auto detect the number of E1 channels and select the available E1 at reset.
Support reset remote system from local system.
Have Ethernet monitor self-reset function.
