ATL User Guide

AM2 G.SHDSL Modem

After restarting your PC, open the Inernet Explorer or Netscape Browser to connect to the AM2. Type in the default IP address for the AM2 into the Address/URL Line of the browser and press the Return key., e.g. http://192.168.0.1

The default IP address and sub net-mask of the AM2 is 192.168.0.1 and 255.255.255.0. Because the AM2 acts as a DHCP server in your network, the AM2 will automatically assign an IP address for your PC in the network.

Note:- If you have two or more AM2 units connected to the same network then you must change the IP address of the AM2.

You will now be prompted to type in the default User Name and Password and click on the OK button.

The default User Name is root.

The default password is root.

For security reasons we suggest you change both the user name and password. Ref to section 6.7

6.4 ROUTING

Various Internet protocols are available i.e. DHCP server, DHCP client, DHCP relay, point-to-point over ATM, Ethernet and IP over ATM and Ethernet over ATM. Prior to setting up the AM2 as a router you must ensure which protocol is provided by the ISP.

6.4.1 DHCP SERVER

Dynamic Host Configuration Protocol (DHCP) is a communication protocol that lets network administrators to manage centrally and automate the assignment of Internet Protocol (IP) addresses in an organization's network. Using the Internet Protocol, each machine that can connect to the Internet needs a unique IP address. When an organization sets up its computer users with a connection to the Internet, an IP address must be assigned to each machine.

Without DHCP, the IP address must be entered manually at each computer. If computers move to another location in another part of the network, a new IP address must be entered. DHCP lets a network administrator supervise and distribute IP addresses from a central point and automatically sends a new IP address when a computer is plugged into a different place in the network. If the DHCP server is Enabled, you have to setup the following parameters for processing it as DHCP server.

The embedded DHCP server assigns network configuration information to most of the 253 users accessing the Internet in the same time.

6.4.2 DHCP CLIENT

Some ISPs provide a DHCP server service by which the LAN can access IP information automatically. To setup the DHCP client mode, follow the procedure.

6.4.3 DCHCP RELAY

If you have a DHCP server in your LAN and you want to use it for DHCP services, the product provides DHCP relay function to meet your needs.

6.4.4 PPPoA & PPPoE

PPPoA (point-to-point protocol over ATM) and PPPoE (point-to-point protocol over Ethernet) are authentication and connection protocols used by many service providers for broadband Internet access. These are specifications for connecting multiple computer users on an Ethernet local area network to a remote site through common customer premises equipment, which is the telephone company's term for a modem and similar devices. PPPoE and PPPoA can be used to office or building. Users share a common Digital Subscriber Line (DSL), cable modem, or wireless connection to the Internet. PPPoE and PPPoA combine the Point-to-Point Protocol (PPP), commonly used in dialup connections, with the Ethernet protocol or ATM protocol, which supports multiple users in a local area network. The PPP protocol information is encapsulated within an Ethernet frame or ATM frame.
