Nokia M5122 ADSL Bridgeā T66250 USER MANUAL
Nokia M5122 ADSL Bridge User Manual C33874.21 B0 02.11.2000 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-speed connections for homes and small offices.
Nokia M5122 User Manual 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.

Nokia M5122 User Manual 2.3 Step-by-step installation procedures In this section, we present two installation procedures: ADSL data services and Telephone and ADSL data services. To use both telephone 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.
5. Connect the ADSL line cable between the DSL connector on the M5122 back panel and the wall socket. After a while, the DSL indicator starts blinking. This indicates that the ADSL line is being established. When the DSL indicator remains lit, the line is functional. 6. During normal operation PWR and DSL indicators are lit and the Ethernet indicators of the active Ethernet ports blink or remain lit depending whether there is traffic or not. COL indicator may blink occasionally during normal operation.

Plug the mains power cord to a mains outlet. M5122 can be connected to an earthed socket outlet only. 2. Switch on M5122. The PWR indicator lights up. After a while, the red STA indicator blinks and then remains unlit. M5122 is now functional. 3.
. During normal operation PWR and DSL indicators are lit and the Ethernet indicators of the active Ethernet ports blink or remain lit depending whether there is traffic or not. COL indicator may blink occasionally during normal operation. Now your M5122 has been connected and you can configure your PC’s networking options and check that the service works according to your service provider’s instructions. 2.4 Troubleshooting This section gives some tips for troubleshooting. Power (PWR) indicator is unlit.
Nokia M5122 User Manual 2.5 Installing M5122 on the wall M5122 can also be wall mounted. Figure 6 shows the installation procedure. 1. Drill two holes (6 mm in diameter) on the wall. The distance between the holes must be 155 mm. Insert the plugs to the holes and fix the screws. 2. Mount the modem on the wall as shown in Figure 6. 1. 6 mm 155 mm 2.
3 Configuring M5122 Your service provider has configured your M5122 for the service. Do not change settings unless specifically asked by your service provider. You can change M5122 settings with an ordinary web browser, such as Microsoft Internet Explorer or Netscape Navigator. Use a PC connected to an ETH port of M5122 for configuration. In this case the corresponding ETH indicator should be lit. 3.
Nokia M5122 User Manual 2. Enter the name (’M5122’) or IP address of your Nokia M5122 in the browser’s Open Location field and press Enter. If you use the IP address, it has to be assigned to a local port or gateway interface (Vbridge). 3. Type in the username/password as requested. If no username/password is required, just click OK to proceed. The Nokia M5122 Main Page appears.
3.1.2 Main Page Main Page is shown first when you use a web browser to connect to M5122. The currently shown page is shown highlighted on the list on the left. Clicking an item on the list (Service Providers, Local Network, Statistics, Restart, and Save Config) takes you to the corresponding page. Note When you make modifications to the configuration, remember to save the configuration if you want your changes to be active after a restart.
Nokia M5122 User Manual 3.1.3 Service providers page You can view network connection information (ATM channel number, VPI and VCI values, and encapsulation) by selecting the connection from the pulldown list. Figure 8 shows the page with eth-llc encapsulation enabled and Figure 9 with PPTP tunneling enabled. Connection name (Figure 9) is used for identifying connections. The name can be changed and it can be 31 characters long.
3.1.4 Local network pages The Local Network page as three sub pages: Local ports, DHCP, and Routing. Local ports page On the Local Network Local Ports sub page you can assign an IP address to the Gateway port (Vbridge). Note When you click Apply, the IP address is changed immediately. If the IP address of the interface you are using changes the connection will be lost. You have to reconfigure the IP address of the accessing host. For example, in Windows programs winipcfg.exe or ipconfig.
Nokia M5122 User Manual DHCP page Note Use DHCP with PPTP tunneling only. On the Local Network DHCP subpage you can enable/disable Dynamic Host Control Protocol and set the Address ranges from which the addresses are distributed to the DHCP clients on your network. You can also set the Domain Name Server addresses here. Start address is the first address in the address range. The Range size defines how many addresses the range contains. Subnet mask is the subnet mask of the addresses in the range.

Nokia M5122 User Manual Routing page On the Local Network Routing sub page you can set static routes and enable/disable dynamic routing protocols (Routing Information Protocol versions 1 and 2). To enable dynamic routing select the Routing protocol version from the pull-down list and click the Apply button. RIP versions 1 and 2 are supported. Both v1 and v2 option enables the receiving of both RIPv1 and RIPv2 packets.
3.1.5 Statistics page The Statistics page lets you view a selection of M5122 statistics. to view statistics of a particular function, click the corresponding button and the statistics view is opened on a separate window.
Nokia M5122 User Manual 3.1.6 Restart page On the Restart page, you can reset subsystems and restart M5122.
3.1.7 Save configuration page When you change the configuration, all configuration changes are activated immediately without restart/reload. However, the configuration will not be saved into the nonvolatile memory. If M5122 is restarted or powered down without saving the configuration, the old configuration will be restored. Clicking the Save configuration button saves the configuration into the nonvolatile memory and the old configuration cannot be restored through the web interface.
Nokia M5122 User Manual maximum transmit rate on the VCC is equal to the ADSL upstream capability. The ADSL transmission is based on the DMT line code. M5122 provides a DMT line rate up to 8 Mbit/s downstream and up to 800 kbit/s upstream. The DMT transceiver is rate adaptive and capable of providing faster rates over short distances or slower rates over long distances. The transceiver adapts itself to the line conditions and rate adaptation is done in steps of 32 kbit/s.
Local tunneling is used when there is a need to have one or more computers connected independently to different networks. For example, in remote work application, the rest of the family may be using the common ISP services and one or two family members need to gain access to their corporate networks. With local tunneling, these remote workers may be connected to a different network than the rest of the users. Local tunneling is activated using the PPTP client running, for example, in Windows.
Nokia M5122 User Manual 4.6 Weighted Fair Queueing (Class of Service) As a Class of Service (CoS) function, M5122 supports Weighted Fair Queueing (WFQ) for each ATM VCC. The CoS function ensures that different IP traffic streams are treated fairly in the upstream (towards the Internet) direction. This may be necessary, in some cases, because the upstream capacity of the ADSL line is somewhat limited compared to the Ethernet bandwidth on the office or home LAN.
