　Sun Telecom’s SUN-EC series of Ethernet convertors apply reverse multiplexing technology to transfer 10M/100M Ethernet data by using E1s. It realizes conversion between 1 to 4/8/16 E1 channels and Ethernet interface. It is capable of providing a real Ethernet throughput of 8Mbps respectively. And it also automatically adapted to lower data rates from 2Mbps, in case that less E1 circuits is employed.
