12	  ISDN ("Integrated Services Digital Networks", called RNIS in France)
13	  is a special type of fully digital telephone service; it's mostly
14	  used to connect to your Internet service provider (with SLIP or
15	  PPP).  The main advantage is that the speed is higher than ordinary
16	  modem/telephone connections, and that you can have voice
17	  conversations while downloading stuff.  It only works if your
18	  computer is equipped with an ISDN card and both you and your service
19	  provider purchased an ISDN line from the phone company.  For
20	  details, read <http://www.alumni.caltech.edu/~dank/isdn/> on the WWW.

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

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

59	  This provides the CAPI (Common ISDN Application Programming
60	  Interface, a standard making it easy for programs to access ISDN
61	  hardware, see <http://www.capi.org/>.  This is needed for AVM's set
62	  of active ISDN controllers like B1, T1, M1.
