Overview
     MEV-LR FE1/V.35+RS232+Eth interface converter support the conversion between E1(N*64K) interface which accord with the ITU-T G.703 standard and V.35 interface. It can realize the function of MEV-LR enhanced interface converter. It can receive synchronous data of 2.048Mbps from E1 network, and transmit the data to ROUTER or other devices. The mode of interface is DCE, and it can be connected with DTE or DCE devices.
