# CONFIG_ISDN device configuration

	---help---
	  CONFIG_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 CONFIG_ISDN
	  adapter you can use it to connect to your Internet service provider
	  (with CONFIG_SLIP or CONFIG_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 CONFIG_ISDN.

if CONFIG_ISDN

menuconfig CONFIG_ISDN_I4L
	tristate "Old ISDN4Linux (deprecated)"
	depends on CONFIG_TTY
	---help---
	  This driver allows you to use an CONFIG_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.  CONFIG_A reduced T.70 protocol is supported with tty's
	  suitable for German BTX.  On CONFIG_D-Channel, the protocols EDSS1
	  (Euro-CONFIG_ISDN) and 1TR6 (German style) are supported.  See
	  <file:Documentation/isdn/README> for more information.

	  CONFIG_ISDN support in the linux kernel is moving towards a new API,
	  called CAPI (Common CONFIG_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.

source "drivers/isdn/i4l/Kconfig"

menuconfig CONFIG_ISDN_CAPI
	tristate "CAPI 2.0 subsystem"
	help
	  This provides CAPI (the Common CONFIG_ISDN Application Programming
	  Interface) Version 2.0, a standard making it easy for programs to
	  access CONFIG_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 CONFIG_ISDN supplementary services like call forwarding or
	  three-party conferences (if supported by the specific hardware
	  driver).

	  Select this option and the appropriate hardware driver below if
	  you have an CONFIG_ISDN adapter supported by the CAPI subsystem.
