You Should Have This Information
CAUTION: You should only have one computer physically connected to the ISDN LAN Modem during configuration. Once you complete the configuration process, connect any other computers you would like to have on the LAN and then power cycle each computer. If the newly-added computers cannot communicate with the ISDN LAN Modem, refer to “Evaluating Symptoms and Solutions” in Chapter 9.
■Telephone number(s) for your ISDN line provided by your telephone company.
■If you want to set up a connection to an ISP, you will also need the telephone number to call for access to your ISP, as well as your user name, password and DNS address (if your service provider requires a DNS address to be configured).

Addresses
A static IP address is a permanent, manually-assigned address recognized by a remote server, such as a corporate LAN or an ISP. By default, your ISDN LAN Modem dynamically assigns an IP address to each computer. If you have been accessing a remote server via a static IP address prior to installing your ISDN LAN Modem, you may be required to perform additional configuration steps. The first step is to determine your static versus dynamic IP addressing scenario.
If you determine that your computer has a static IP address, refer to “Setting Up Your Computer If You Have a Static IP Address.” If your computer has a dynamic IP address, you may begin configuring the ISDN LAN Modem directly. Refer to “Configuring the ISDN LAN Modem for the Typical Configuration.”
Determine your IP address type as follows:
■ For Windows 98, 95 and NT 4.0 Users: From the Start menu, select Settings and then Control Panel. Double-clickNetwork. Select TCP/IP for the Ethernet card you will attach to the ISDN LAN Modem and then click Properties. Select the IP Address tab. If the radio button labeled Obtain an IP address automatically (Windows 98 and 95) or labeled Obtain an IP address from a DHCP server (Windows NT 4.0) is selected, your computer has a dynamic IP address. If the radio button labeled Specify an IP address is selected, your computer has a static IP address.
■ For Mac Users: From the Apple menu, open Control Panels. Double-click TCP/IP. Choose Ethernet or Ethernet built in from the Connect via drop-down list box, if it is not already chosen. If the Configure drop down list box is set to Using DHCP Server, then you are on a dynamic network and are ready to continue directly with “Installing the ISDN LAN Modem.” If Configure is not set to Using DHCP Server and you have specific values listed in any of the following fields: IP Address, Subnet mask, Router address, or Name server addr., then your computer has a static IP address.
■ For Windows 3.11 Users: From the Program Manager, double-click the Network program group icon. Double-click the Network Setup icon. Click the Drivers button. Highlight the Microsoft TCP/IP - 32.X entry and click Setup. If Enable DHCP Configuration is checked, then your computer has a dynamic IP address. If an IP address is entered in the IP Address box, then your computer has a static IP address.
