Overview
MEV-135F FE1/V.35 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 not only realize the function of MEV-100 enhanced interface converter, but also can fulfill rate converter and pick-up time. 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. Features
﹛↑ Adopting HDB3 line code
﹛↑ Fully compatible with ITU-T V.35, G.703, G.704 standard
﹛↑ E1 and V.35 interfaces can realize internal loop
﹛↑ Line rate: N*64Kbps, N=(1~31)
﹛↑ Frame format: frame
﹛↑ E1 line code: compliant with ITU-T V.35, G.703, G.704
