Installing on an existing LAN

Installing the DIVA LAN ISDN Modem on an existing LAN can be extremely simple, or quite challenging, depending on the complexity of your existing LAN setup. To help you successfully integrate the DIVA LAN ISDN Modem into your setup, this section presents an installation strategy that should work in the majority of cases. However, due to the wide range of networking equipment and topologies that are in use worldwide, your configuration needs may fall outside the strategy presented here. In this case, you should contact your network administrator, or other support person to help you with your installation.

Using Modem Monitor

Modem Monitor greatly simplifies the task of installing the DIVA LAN ISDN Modem on a LAN. If at least one of the computers on your LAN is running Windows 95/98/NT, follow the instructions in Chapter Two to install and configure the DIVA LAN ISDN Modem. However, make the following exceptions:

•Instead of connecting the DIVA LAN ISDN Modem directly to your computers, connect it to the LAN. Do this by connecting any one of the DIVA LAN ISDN Modem’s ETHERNET ports to a port on your LAN hub.

If your hub has a cross-over switch or cascade port, you can use the supplied blue Ethernet cable to make this connection. If not, you will need a special cross-over Ethernet cable to make this connection.

Try connecting the supplied blue cable to the hub, if the green Ethernet light on the DIVA LAN ISDN Modem does not light up, you need a special cross-over cable.

•Install the Modem Monitor software on a Windows 95/98/NT computer that is connected to the LAN. Modem Monitor will automatically detect the DIVA LAN ISDN Modem and let you adjust its IP settings for proper operation on the LAN.

Once installation is complete, you may need to adjust the configuration settings of the computers on your LAN. See “Adjusting configuration settings on the LAN” on page 114 for complete details.

Manual installation

Follow these steps to install the DIVA LAN ISDN Modem on a LAN if you are unable to run Modem Monitor on a computer on your network.

1.Determine how IP addresses are assigned on the LAN.

•Static: Each computer on your LAN has a fixed address. If this is the case, then determine the IP address and subnet mask that will be assigned to the DIVA LAN ISDN Modem.

•Dynamic: Addresses are assigned by a DHCP server (such as a Windows NT server).

It is recommended that before you install the DIVA LAN ISDN Modem on your LAN, you should install and configure it for use with a single non-networked computer. This lets you verify that your ISDN line is functioning and that you are able to successfully communicate with the DIVA LAN ISDN Modem.

2.Disconnect a computer from your LAN.

3.Follow the instructions in Chapter Two to install and configure the DIVA LAN ISDN Modem. Pay particular attention to section “Verify the configuration of your computers” on page 18. If you need to change the settings of your computer, make sure you record the existing settings before you change them.

4.Once installation and configuration are complete, confirm that your ISDN line works and that you have access to the Internet.

5.Start the Web-based configuration interface.
