Introduction to Nokia M5122

Nokia M5122 is an ADSL bridge which enables high-speed Internet
access and LAN interconnection. It increases the capacity of the
already installed telephone lines used traditionally for telephone
services. M5122 enables high-speed connections for homes and small
offices.

Nokia M5122 allows multiple PCs equipped with a 10Base-T Ethernet
interface to be connected to a remote network via a Digital Subscriber
Line Access Multiplexer (DSLAM) and an ATM access network. It
acts as a bridge between the Ethernet LAN and ADSL/ATM network
interfaces. An in-built 4-port hub allows easy home and small office
network installation.
