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.

The isdn-tty's have a built 31 in AT-compatible modem emulator. Network devices support autodial, 32 channel-bundling, callback and caller-authentication without having 33 a daemon running. A reduced T.70 protocol is supported with tty's 34 suitable for German BTX. On D-Channel, the protocols EDSS1 35 (Euro-ISDN) and 1TR6 (German style) are supported. See 36 <file:Documentation/isdn/README> for more information. 37 38 ISDN support in the linux kernel is moving towards a new API, 39 called CAPI (Common ISDN Application Programming Interface). 40 Therefore the old ISDN4Linux layer will eventually become obsolete. 41 It is still available, though, for use with adapters that are not 42 supported by the new CAPI subsystem yet. 43 44if ISDN_I4L 45source "drivers/isdn/i4l/Kconfig" 46endif 47 48menuconfig ISDN_CAPI 49 tristate "CAPI 2.0 subsystem" 50 help 51 This provides the CAPI (Common ISDN Application Programming 52 Interface, a standard making it easy for programs to access ISDN 53 hardware, see <http://www.capi.org/>.
