- ISDN ("Integrated Services Digital Networks", called RNIS in France)
- is a special type of fully digital telephone service; it's mostly
- used to connect to your Internet service provider (with SLIP or
- PPP). The main advantage is that the speed is higher than ordinary
- modem/telephone connections, and that you can have voice
- conversations while downloading stuff. It only works if your
- computer is equipped with an ISDN card and both you and your service
- provider purchased an ISDN line from the phone company. For
- details, read <http://www.alumni.caltech.edu/~dank/isdn/> on the WWW.

+ adapter you can use it to connect to your Internet service provider
+ (with SLIP or PPP) faster than via a conventional telephone modem
+ (though still much slower than with DSL) or to make and accept
+ voice calls (eg. turning your PC into a software answering machine
+ or PABX).
Select this option if you want your kernel to support ISDN.
