1 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-speedconnections for homesandsmall
offices.

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.

2 Installing M5122
Before installing M5122, you may want to familiarise yourself with
the interfaces and indicator lights of M5122. From section 2.3, you
will find a step-by-step installation procedure, which shows the
physical installation of M5122.
2.1 Interfaces
M5122 has one ADSL line interface and four Ethernet interfaces
(10Base-T). It also has a Command Line Interface (CLI) for
management purposes. The ADSL line interface is compatible with
ITU-T G.992.1 specification.

2.3 Step-by-step installation procedures
In this section, we present two installation procedures: ADSL data
servicesandTelephoneandADSLdataservices.Tousebothtelephone
and ADSL services, you will need a POTS splitter. This manual gives
installation example for a Nokia splitter T66270.
In these examples, we assume that you have installed your Ethernet
card properly and that your service provider has provided you with
instructions how to set your PC’s networking options.

2.4 Troubleshooting
This section gives some tips for troubleshooting.
Power (PWR) indicator is unlit.
Make sure that power cord has been connected to a mains outlet and
M5122 has been switched on.
Red status (STA) indicator is lit
Switch power off and then on again. If the STA indicator remains lit,
the unit may be faulty.
ADSL (DSL) indicator is unlit
Make sure that the ADSL line cable has been properly connected
between the DSL connector and the wall socket.
Ethernet (ETH-) indicator is unlit
Make sure that the Ethernet cable has been properly connected
between your PC’s Ethernet interface and the M5122 ETH connector.
Make sure that your PC is ON.
You cannot access the Internet
1. Make sure that your M5122 is ON.
2. Check that the DSL indicator is lit.
3. CheckthatEthernet indicator(ETH-1, ETH-2,ETH-3,orETH-4)
corresponding to the Ethernet interface you are connected to is
ON.
4. Make sure that your PC’s networking functions have been
configured according to your service provider’s instructions.
