Product description
The EFM-20 is an Ethernet Network Extender using bonded G.shdsl.bis technology over copper wires. Unit supports EFM (Ethernet First Mile) 2Base-TL technology, a collection of standards for Ethernet over LAN, MAN and WAN deployments. EFM-20 uses the 802.3ah management protocol, making it a very powerful unit for service providers and providing all needed mass deployment features. EFM-20 has a 4 port Ethernet switch with advanced VLAN and QoS capabilities. Management includes web-based interface, SNMP, telnet CLI interface and local console port.

The EFM-20 can provide 11.4Mbps of data throughput on a 4 wire (2 pairs) AWG26 copper lines. QoS services can help setting ingress/egress data rates and data traffic can be proritized according to WRR/ BE or SP rules. EFM-20 can be used in point to point connections.
