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).
18
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.
35
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.

46	help
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.
