  11           ISDN ("Integrated Services Digital Network", called RNIS in France)
  12           is a fully digital telephone service that can be used for voice and
  13           data connections.  If your computer is equipped with an ISDN
  14           adapter you can use it to connect to your Internet service provider
  15           (with SLIP or PPP) faster than via a conventional telephone modem
  16           (though still much slower than with DSL) or to make and accept
  17           voice calls (eg. turning your PC into a software answering machine
  18           or PABX).

  28           This driver allows you to use an ISDN adapter for networking
  29           connections and as dialin/out device.  The isdn-tty's have a built
  30           in AT-compatible modem emulator.  Network devices support autodial,
  31           channel-bundling, callback and caller-authentication without having
  32           a daemon running.  A reduced T.70 protocol is supported with tty's
  33           suitable for German BTX.  On D-Channel, the protocols EDSS1
  34           (Euro-ISDN) and 1TR6 (German style) are supported.  See
  35           <file:Documentation/isdn/README> for more information.
  36
  37           ISDN support in the linux kernel is moving towards a new API,
  38           called CAPI (Common ISDN Application Programming Interface).
  39           Therefore the old ISDN4Linux layer will eventually become obsolete.
  40           It is still available, though, for use with adapters that are not
  41           supported by the new CAPI subsystem yet.

  48           This provides CAPI (the Common ISDN Application Programming
  49           Interface) Version 2.0, a standard making it easy for programs to
  50           access ISDN hardware in a device independent way. (For details see
  51           <http://www.capi.org/>.)  CAPI supports making and accepting voice
  52           and data connections, controlling call options and protocols,
  53           as well as ISDN supplementary services like call forwarding or
  54           three-party conferences (if supported by the specific hardware
  55           driver).

  57           Select this option and the appropriate hardware driver below if
  58           you have an ISDN adapter supported by the CAPI subsystem.
