actual rate depends on the copper category of your telephone wires, distance from the central office and the
type of DSL service you subscribe to. Its 10/100M auto-negotiating LAN interface enables fast data transfer
of either 10Mbps or 100Mbps in either half-duplex or full-duplex mode depending on your Ethernet
network.

session VPN capability.

immunity from background noise.
