SEOP 4E1 FE Ethernet Converter

Ascent’s 4E1-4*10/100BT serial interface converter used back multiplexing technology, transfer 10M/100M Ethernet data by using multi E1 channels. The unit converts between 1 to 4 E1 channels and Ethernet interface. It can transmit signal of E1 channel to RJ45 interface point to point, allowing the connection of E1 channel and Ethernet. It differs from normal bridge, supporting 1 to 4 E1 channels customized configuration, auto detecting the number of E1 channels and use the available E1, allowing some limiting transfer delay between different E1 channels. 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. This converter can be used in fields such as connecting LANs, connecting end offices, VOD, remote monitor, E1 interface of switches, etc.

·            Offers transparent transfer 4*Ethernet over 4E1 TDM
