Ethernet over SDH/PDH
At present telecom operators and large companies have built metropolitan and long-distance networks based on SDH and PDH technology. Initially this networks was intended for telephone communications over E1 (PRI, 2Mbps) channels. We suggest the solution for Ethernet transmission over E1 channels at data rates from 64kbps to 16Mbps.
