Description:AN-8E1-ETH mux provides conversion from 1 to 8 E1 channels to Ethernet interface. Supports 1 to 8 E1 channels setting, it can detect the number of E1 channel and select available channel. If you need transmit you LAN over 8 x E1 lines, using some E1 G.703 access network - then this is your right solution! You will get 16 Mbit/s buy multiplexing 8 x E1 lines... The AN-8E1-ETH inverse multiplexers transmit up to 16 Mbps channel over multiple E1 links. They bridge the gap between E1 and E3, allowing bridges and routers to operate at their fastest rates. The AN-8E1-ETH have a built-in 10/100 Ethernet bridge with VLAN support for LAN-to-LAN applications over 8 E1 links. The AN-8E1-ETH fully meets all of the E1 specifications including G.703, G.704, G.706, G.732 and G.823. The unit features diagnostic capabilities for performing remote loopback tests. AN-8E1-ETH features: - Made according with IEEE 802.3, support 10Base-T,100Base-T. - Support flexible setting of 1 to 4 E1 channels, auto detect the number of E1 channels and time-delay, select available E1 channels when reset. - Provide 2 loop functions: Local E1 loop, remote E1 loop. - Ethernet transmission transparent, support AUTO-MDIX, straight and crossover auto-adapt. - Can transmit super-long frame of IEEE 802.1Q, support Ethernet exchanger with VLAN function. - Support E1 channel hot plug, and auto detect available E1 channels. - Support reset remote system from local system. 8 E1 can have 10 ms time-delay, CRC alarm limitation can auto insulate bad-quality transmit channel by configuration, and is single direction insulation. When one direction error rate over limitation, cut only this direction, the other direction not affected. ( the two directions need not symmetry. ) - Power supply option: AC220V, DC-48V. The positive and negative terminal can be exchanged for DC-48V, easy for installation and maintenance. - Network manager interface use SNMP Ordering information AN-8E1-ETH/AC 8xE1-ETH interface convertor,75/120,220V AN-8E1-ETH/DC/48 8xE1-ETH interface convertor,75/120, DC-48V AN-8E1-ETH/DC/24 8xE1-ETH interface convertor,75/120, DC+24V And most important - even if 1 of E1's goes down... Our mux reacts immediatelly by rebalancing load on left ones! Ask more info now...
