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

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

  26        ---help---
  27          This driver allows you to use an ISDN adapter for networking
  28          connections and as dialin/out device.  The isdn-tty's have a built
  29          in AT-compatible modem emulator.  Network devices support autodial,
  30          channel-bundling, callback and caller-authentication without having
  31          a daemon running.  A reduced T.70 protocol is supported with tty's
  32          suitable for German BTX.  On D-Channel, the protocols EDSS1
  33          (Euro-ISDN) and 1TR6 (German style) are supported.  See
  34          <file:Documentation/isdn/README> for more information.

  36          ISDN support in the linux kernel is moving towards a new API,
  37          called CAPI (Common ISDN Application Programming Interface).
  38          Therefore the old ISDN4Linux layer will eventually become obsolete.
  39          It is still available, though, for use with adapters that are not
  40          supported by the new CAPI subsystem yet.

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