+ 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.
+
+ Select this option if you want your kernel to support ISDN.

+ ---help---
+ This driver allows you to use an ISDN-card for networking
+ connections and as dialin/out device. The isdn-tty's have a built
+ in AT-compatible modem emulator. Network devices support autodial,
+ channel-bundling, callback and caller-authentication without having
+ a daemon running. A reduced T.70 protocol is supported with tty's
+ suitable for German BTX. On D-Channel, the protocols EDSS1
+ (Euro-ISDN) and 1TR6 (German style) are supported. See
+ <file:Documentation/isdn/README> for more information.
+
+ ISDN support in the linux kernel is moving towards a new API,
+ called CAPI (Common ISDN Application Programming Interface).
+ Therefore the old ISDN4Linux layer is becoming obsolete. It is
+ still usable, though, if you select this option.

+ This provides the CAPI (Common ISDN Application Programming
+ Interface, a standard making it easy for programs to access ISDN
+ hardware, see <http://www.capi.org/>. This is needed for AVM's set
+ of active ISDN controllers like B1, T1, M1.
