+	  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.
