2 # ISDN device configuration
9 tristate "ISDN support"
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.

29 tristate "Old ISDN4Linux (obsolete)"
31 This driver allows you to use an ISDN-card 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.
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 is becoming obsolete. It is
43 still usable, though, if you select this option.

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