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

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

54 tristate "CAPI2.0 support"
57 This provides the CAPI (Common ISDN Application Programming
58 Interface, a standard making it easy for programs to access ISDN
59 hardware, see <http://www.capi.org/>. This is needed for AVM's set
60 of active ISDN controllers like B1, T1, M1.
