# # ISDN device configuration # menu "ISDN subsystem" config ISDN tristate "ISDN support" depends on NET ---help--- ISDN ("Integrated Services Digital Networks", called RNIS in France) is a special type of fully digital telephone service; it's mostly used to connect to your Internet service provider (with SLIP or PPP). The main advantage is that the speed is higher than ordinary modem/telephone connections, and that you can have voice conversations while downloading stuff. It only works if your computer is equipped with an ISDN card and both you and your service provider purchased an ISDN line from the phone company. For details, read on the WWW. Select this option if you want your kernel to support ISDN. menu "Old ISDN4Linux" depends on NET && ISDN config ISDN_I4L tristate "Old ISDN4Linux (obsolete)" ---help--- This driver allows you to use an ISDN-card 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 is becoming obsolete. It is still usable, though, if you select this option. if ISDN_I4L source "drivers/isdn/i4l/Kconfig" endif endmenu comment "CAPI subsystem" depends on NET && ISDN config ISDN_CAPI tristate "CAPI2.0 support" depends on ISDN help This provides the CAPI (Common ISDN Application Programming Interface, a standard making it easy for programs to access ISDN hardware, see .
