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.

3. Connect the Ethernet cable between your PC’s 10Base-T

connector and the Ethernet connector on the M5122 back panel

(ETH-1, ETH-2, ETH-3, or ETH-4).

4. Switchonyour PC. The indicatorcorresponding the Ethernet port

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.
