ISDN ("Integrated Services Digital Network", called RNIS in France)
|
|
|
|
|
is a fully digital telephone service that can be used for voice and
|
|
|
|
|
data connections. If your computer is equipped with an ISDN
|
|
|
|
|
adapter you can use it to connect to your Internet service provider
|
|
|
|
|
(with SLIP or PPP) faster than via a conventional telephone modem
|
|
|
|
|
(though still much slower than with DSL) or to make and accept
|
|
|
|
|
voice calls (eg. turning your PC into a software answering machine
|
|
|
|
|
or PABX).
|
|
|
|
|
|
|
|
|
|
Select this option if you want your kernel to support ISDN.

This driver allows you to use an ISDN adapter for networking
|
|
|
|
|
connections and as dialin/out device. The isdn-tty's have a built
|
|
|
|
|
in AT-compatible modem emulator. Network devices support autodial,
|
|
|
|
|
channel-bundling, callback and caller-authentication without having
|
|
|
|
|
a daemon running. A reduced T.70 protocol is supported with tty's
|
|
|
|
|
suitable for German BTX. On D-Channel, the protocols EDSS1
|
|
|
|
|
(Euro-ISDN) and 1TR6 (German style) are supported. See
|
|
|
|
|
<file:Documentation/isdn/README> for more information.

ISDN support in the linux kernel is moving towards a new API,
|
|
|
|
|
called CAPI (Common ISDN Application Programming Interface).
|
|
|
|
|
Therefore the old ISDN4Linux layer will eventually become obsolete.
|
|
|
|
|
It is still available, though, for use with adapters that are not
|
|
|
|
|
supported by the new CAPI subsystem yet.

This provides CAPI (the Common ISDN Application Programming
|
|
|
|
|
Interface) Version 2.0, a standard making it easy for programs to
|
|
|
|
|
access ISDN hardware in a device independent way. (For details see
|
|
|
|
|
<http://www.capi.org/>.) CAPI supports making and accepting voice
|
|
|
|
|
and data connections, controlling call options and protocols,
|
|
|
|
|
as well as ISDN supplementary services like call forwarding or
|
|
|
|
|
three-party conferences (if supported by the specific hardware
|
|
|
|
|
driver).
|
|

you have an ISDN adapter supported by the CAPI subsystem.
