2 # ISDN device configuration
6 tristate "ISDN support"
10 ISDN ("Integrated Services Digital Networks", called RNIS in France)
11 is a special type of fully digital telephone service; it's mostly
12 used to connect to your Internet service provider (with SLIP or
13 PPP). The main advantage is that the speed is higher than ordinary
14 modem/telephone connections, and that you can have voice
15 conversations while downloading stuff. It only works if your
16 computer is equipped with an ISDN card and both you and your service
17 provider purchased an ISDN line from the phone company. For
18 details, read <http://www.alumni.caltech.edu/~dank/isdn/> on the WWW.
20 Select this option if you want your kernel to support ISDN.
25 tristate "Old ISDN4Linux (deprecated)"
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 tristate "CAPI 2.0 subsystem"
49 This provides the CAPI (Common ISDN Application Programming
50 Interface, a standard making it easy for programs to access ISDN
51 hardware, see <http://www.capi.org/>. This is needed for AVM's set
52 of active ISDN controllers like B1, T1, M1.
