Figure 1-1 Nokia M1122 M1122 allows you to connect your desktop and laptop PCs to remote networks. Your PCs must be equipped with a 10Base-T Ethernet interface. M1122 has an in-built 4-port hub, which allows easy home network installation.

However, these figures illustrate the maximum performance of the technology and are subjected to the physical line conditions and the distance from you to the central office. M1122 is capable of adapting to the physical line conditions and guarantees the maximum transmission rate possible on the particular line.
Applications and features In this chapter, we present the most common applications and features of M1122. The use and configuration of your Nokia M1122 may be different from the configurations presented in this manual, even for similar applications. The configurations presented in this manual represent a typical way of using M1122 for the corresponding applications.

Internet address. Furthermore, it prevents others from seeing and accessing your private network and therefore it acts as a simple firewall.

Remote work Another application for M1122 is remote work. In this case the end-to-end architecture can, for example, use PPP over Ethernet, where a dial-up-type PPP connection is created between your home PC and your corporate networks PPP access server based on the user name and password you issue in your PC.
Figure 2-3 LAN interconnection Features M1122 can operate as a bridge and/or Internet Protocol (IP) router between the Ethernet and the virtual channels of ADSL/ATM interfaces supporting both dynamic and static routing. 2.2.1 Interfaces M1122 has the following interfaces:...
Page 16
In this manual it is called VBRIDGE. On the M1122 web pages, the interface is called gateway or bridge IP interface. M1122 can operate in four different main modes:...
IP packets. Bridging and routing; Bridging is activated in the interface and IP address is configured in the interface. In this case, the interface routes IP packets and bridges all other packets. E Copyright Nokia Networks Oy C33906001SE_00...
Internal host/gateway interface There is a special host/gateway logical IP interface within M1122 called VBRIDGE. This interface has a specific purpose in M1122. In applications where some ATM virtual channel connections are used for bridging IP traffic and some other ATM virtual channel connections are used for routing IP traffic, the VBRIDGE interface must be used instead of LAN IP address.
Optionally, the bridging between the VCCs can be disabled. 2.2.4 Network Address Port Translation M1122 supports Network Address Port Translation (NAPT) for TCP/IP, UDP/IP and ICMP/IP protocols. When NAPT is used, a single IP address is allocated to a VCC which leads to the public IP network.
253 addresses are required on the local subnet, if two non-contiguous address ranges are needed or if an additional router with DHCP relay is used on the local network. M1122 can also act as a DHCP relay agent and relay the DHCP requests to an external DHCP server.
Automatic, chooses the first free VCC Chooses the VCC number using C:number, where number is from 1 to 8. C:number is typed after the M1122 IP address in PC’s PPTP client Connect To window (see Figure 2-5). Chooses the VCC number using N:name, where name is the VCCx description.
Choosing the VCC2 for tunneling example 2.2.8 Point-to-Point Protocol over Ethernet (PPPoE) Standard PPPoE mode is used when M1122 is operating as a bridge. PPPoE protocol defines how PPP sessions are mapped into Ethernet packets. When M1122 operates as a bridge, this protocol is transparent to M1122.
The operator or the Internet Service Provider can establish a dedicated management channel to M1122. This channel provides access to the M1122 management (with telnet or web browser) and it can be used to upload a new software to M1122.

Chapter 3 Interfaces and indicator lights This chapter describes the external interfaces of M1122 and introduces its front panel indicator lights. Interfaces M1122 has one ADSL line interface and four LAN interfaces (10Base-T Ethernet). It also has a local management interface (CLI) for management purposes.
Ethernet interface pin-out numbering 3.1.2 ADSL interface The ADSL interface (DSL) is compatible with ITU-T G.992.1 specification. The mechanical connector is a 6-pin RJ-11. The pin-out numbering is shown in Table 3-2. Figure 3-3 DSL connector E Copyright Nokia Networks Oy C33906001SE_00...

M1122 Administrator Manual Indicator lights M1122 has eight indicator lights on the front panel: PWR, STA, COL, ETH-1, ETH-2, ETH-3, ETH-4, and DSL. STA indicator is red. Other indicators are green. Figure 3-5 M1122 front panel indicators GREEN ADSL link is down.

After the operational examples, we introduce the management methods of M1122. First we show how to use the web browser management and then the command line interface (CLI) will be presented.
If the application requires only routing of IP packets, an IP address should be configured for each interface in use. The example below shows a typical configuration in such a case. M1122> show conf running ip address 192.168.1.1 255.255.255.0 vcc1 pvc 0 101 ip-llc ip address 10.98.16.1 255.255.255.0...
In the configuration example below, LAN interface routes IP traffic and bridges all other protocols. ATM VCC1 routes IP traffic and ATM VCC2 interfaces bridges all traffic. M1122> show config running ip address 192.168.1.1 255.255.255.0 bridging vcc1 pvc 0 101 ip-llc ip address 10.98.16.1 255.255.255.0...
Note After you have made changes to the configuration, you must save the configuration if you want it to be active also after restarting M1122. 5.2.1 Configuring DHCP and DNS The DHCP server can be enabled towards LAN and VBRIDGE ports.
5.2.2 Configuring static and dynamic routing Routing entries in the routing table are needed in order to forward the IP packets to the correct interface. M1122 has both static and dynamic routes. Static routes are configured manually and dynamic routes are learned automatically using RIP v1 and RIP v2 protocols.
0.0.0.0 instead of the next hop address. 5.2.3 File system and downloading new firmware using TFTP M1122 has a flash file system. Some files in the file system have special meanings. These files are: image.exe; primary application file.
2. After you will see transfer status SUCCESSFUL message, restart M1122 to activate the new software. Downloading configuration or application from monitor Monitor is a small application that is executed before the actual software image is started. Typically the Monitor automatically loads the application file image.exe.
Writing successful MON> Browser management M1122 can be managed with a web browser or command line interface (CLI). The web configuration pages of M1122 can be accessed through the Ethernet ports or through the ADSL/ATM channels of M1122. In order to access the web management feature, the IP functionality must be activated and an IP address must be given to the corresponding interface.
To open a connection to the Nokia M1122: 1. Start your web browser. 2. Enter the name (’M1122’) or IP address of your Nokia M1122 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).
5.3.2 Main Page Main Page is shown first when you use a web browser to connect to M1122. 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.

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 M1122 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.

Local management cabling The command line interface can also be accessed through the Ethernet port of M1122 or through the ATM channels of M1122 on top of the telnet protocol. In order to use the CLI through telnet or the ATM channel, the IP function must be switched on and IP address must be given to the corresponding interface.
