- 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.
+ ISDN ("Integrated Services Digital Network", called RNIS in France)

+ (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.

1. Rewrite the outdated help texts for config options ISDN and ISDN_CAPI. 2. The MISDN config option appeared between ISDN_I4L and the I4L hardware driver options; move it to a less irritating place. 3. HYSDN is not in fact an I4L driver, and needn't depend on ISDN_I4L, so move it from the I4L section to the general section. 4. ISDN_HDLC is now also used by drivers outside I4L. Move it from the I4L section to the general section, too.
