E1 to 10 / 100Base-T Protocol Converter is a conversion device that can realize the conversion from E1 interface to 10 / 100Base-T interface. Provides 2048Kbit / s date transmission channel for line concentrator or exchanger to combine two LANs into one LANs via transmission apparatus (such as optical transmitter / receiver and so on) and use same IP address. Supports automatic learning MAC address function. Filtrate data package via address list and be transparent in TCP/ IP protocol.
