Setting up an ISDN line
If you’re interested in setting up an ISDN line, first contact your local phone company to see if ISDN
service is available at your location. Your phone company can also provide specific information about
monthly charges and usage fees. ( Your phone company may also charge an installation fee, which is
sometimes waived or refunded if you agree to keep the ISDN line for a specified amount of time.)
In addition, you need to purchase either an ISDN terminal adapter or an ISDN PCI expansion card. 
The ISDN terminal adapter, also called an ISDN modem, is an external device that plugs into the
modem port on the back of the computer. The ISDN PCI expansion card is an internal device that you
install into the computer’s PCI expansion slot. Either the terminal adapter or the PCI expansion card
can supply the ISDN port where you connect your ISDN line.
Some ISDN equipment may be difficult to configure with the network configuration of your employer
or Internet service provider (ISP). Work closely with your Internet service provider or computer
network administrator to make sure you purchase compatible ISDN equipment.
Shared telecommunications equipment on your network
One of the advantages of a local area network is that you can share equipment, such as printers and file
servers. If your computer is linked by a cable connection to a local area network, there may also be
shared telecommunications equipment connected to the network that allows you (or anyone else on
your network) to connect to the Internet or an online service. Contact your network administrator for
more information. You can also find general information about networks in Chapter 6, “Connecting
Your Computer to a Network.”
