The main advantage is that the speed is higher than ordinary 14 modem/telephone connections, and that you can have voice 15 conversations while downloading stuff. It only works if your 16 computer is equipped with an ISDN card and both you and your service 17 provider purchased an ISDN line from the phone company. For 18 details, read <http://www.alumni.caltech.edu/~dank/isdn/> on the WWW. 19 20 Select this option if you want your kernel to support ISDN. 21 22if ISDN 23 24config ISDN_I4L 25 tristate "Old ISDN4Linux (deprecated)" 26 ---help--- 27 This driver allows you to use an ISDN adapter for networking 28 connections and as dialin/out device. The isdn-tty's have a built 29 in AT-compatible modem emulator. Network devices support autodial, 30 channel-bundling, callback and caller-authentication without having 31 a daemon running. A reduced T.70 protocol is supported with tty's 32 suitable for German BTX. On D-Channel, the protocols EDSS1 33 (Euro-ISDN) and 1TR6 (German style) are supported. See 34 <file:Documentation/isdn/README> for more information. 35 36 ISDN support in the linux kernel is moving towards a new API, 37 called CAPI (Common ISDN Application Programming Interface). 38 Therefore the old ISDN4Linux layer will eventually become obsolete. 39 It is still available, though, for use with adapters that are not 40 supported by the new CAPI subsystem yet. 41 42if ISDN_I4L 43source "drivers/isdn/i4l/Kconfig" 44endif 45 46config ISDN_CAPI 47 tristate "CAPI 2.0 subsystem" 48 help 49 This provides the CAPI (Common ISDN Application Programming 50 Interface, a standard making it easy for programs to access ISDN 51 hardware, see <http://www.capi.org/>.
