The main advantage is that the speed is higher than ordinary 151da177e4SLinus Torvalds modem/telephone connections, and that you can have voice 161da177e4SLinus Torvalds conversations while downloading stuff. It only works if your 171da177e4SLinus Torvalds computer is equipped with an ISDN card and both you and your service 181da177e4SLinus Torvalds provider purchased an ISDN line from the phone company.

The isdn-tty's have a built 321da177e4SLinus Torvalds in AT-compatible modem emulator. Network devices support autodial, 331da177e4SLinus Torvalds channel-bundling, callback and caller-authentication without having 341da177e4SLinus Torvalds a daemon running. A reduced T.70 protocol is supported with tty's 351da177e4SLinus Torvalds suitable for German BTX. On D-Channel, the protocols EDSS1 361da177e4SLinus Torvalds (Euro-ISDN) and 1TR6 (German style) are supported.

It is 421da177e4SLinus Torvalds still usable, though, if you select this option. 431da177e4SLinus Torvalds 441da177e4SLinus Torvaldsif ISDN_I4L 451da177e4SLinus Torvaldssource "drivers/isdn/i4l/Kconfig" 461da177e4SLinus Torvaldsendif 471da177e4SLinus Torvalds 481da177e4SLinus Torvaldsendmenu 491da177e4SLinus Torvalds 501da177e4SLinus Torvaldscomment "CAPI subsystem" 511da177e4SLinus Torvalds depends on NET && ISDN 521da177e4SLinus Torvalds 531da177e4SLinus Torvaldsconfig ISDN_CAPI 541da177e4SLinus Torvalds tristate "CAPI2.0 support" 551da177e4SLinus Torvalds depends on ISDN 561da177e4SLinus Torvalds help 571da177e4SLinus Torvalds This provides the CAPI (Common ISDN Application Programming 581da177e4SLinus Torvalds Interface, a standard making it easy for programs to access ISDN 591da177e4SLinus Torvalds hardware, see <http://www.capi.org/>.
