# # ISDN device configuration # menuconfig ISDN bool "ISDN support" depends on NET && NETDEVICES depends on !S390 && !UML ---help--- 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. if ISDN menuconfig ISDN_I4L tristate "Old ISDN4Linux (deprecated)" depends on TTY ---help--- 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 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. source "drivers/isdn/i4l/Kconfig" menuconfig ISDN_CAPI tristate "CAPI 2.0 subsystem" help 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 .) 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). Select this option and the appropriate hardware driver below if you have an ISDN adapter supported by the CAPI subsystem. if ISDN_CAPI source "drivers/isdn/capi_oslib/Kconfig" source "drivers/isdn/capi_codec/Kconfig" source "drivers/isdn/avm_dect/Kconfig" source "drivers/isdn/capi/Kconfig" source "drivers/isdn/hardware/Kconfig" endif # ISDN_CAPI source "drivers/isdn/gigaset/Kconfig" source "drivers/isdn/hysdn/Kconfig" source "drivers/isdn/mISDN/Kconfig" config ISDN_HDLC tristate select CRC_CCITT select BITREVERSE endif # ISDN
