Certification:ISO9001:20001 FE1/10BaseT converter adopts telecom line (E1 or E1 transmitting network,such as PDH, SDH, microwave, etc) to extend Ethernet. It converts Ethernet frame structure to E1 frame structure, and recovers E1 frame structure to Ethernet frame structure at the other side, which enables Ethernet data to transmit in telecom network based on E1. Because it is efficiently and effectively used the spare bandwidth of telecom providers, it saves the networking cost and improve the efficiency and can be used immediately.
