          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 adapter 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 will eventually become obsolete.
          It is still available, though, for use with adapters that are not
          supported by the new CAPI subsystem yet.

          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.
