The main advantage is that the speed is higher than ordinary 15 modem/telephone connections, and that you can have voice 16 conversations while downloading stuff. It only works if your 17 computer is equipped with an ISDN card and both you and your service 18 provider purchased an ISDN line from the phone company. For 19 details, read <http://www.alumni.caltech.edu/~dank/isdn/> on the WWW. 20 21 Select this option if you want your kernel to support ISDN. 22 23 24menu "Old ISDN4Linux" 25 depends on NET && ISDN 26 27config ISDN_I4L 28 tristate "Old ISDN4Linux (obsolete)" 29 ---help--- 30 This driver allows you to use an ISDN-card for networking 31 connections and as dialin/out device. The isdn-tty's have a built 32 in AT-compatible modem emulator. Network devices support autodial, 33 channel-bundling, callback and caller-authentication without having 34 a daemon running. A reduced T.70 protocol is supported with tty's 35 suitable for German BTX. On D-Channel, the protocols EDSS1 36 (Euro-ISDN) and 1TR6 (German style) are supported. See 37 <file:Documentation/isdn/README> for more information. 38 39 ISDN support in the linux kernel is moving towards a new API, 40 called CAPI (Common ISDN Application Programming Interface). 41 Therefore the old ISDN4Linux layer is becoming obsolete. It is 42 still usable, though, if you select this option. 43 44if ISDN_I4L 45source "drivers/isdn/i4l/Kconfig" 46endif 47 48endmenu 49 50comment "CAPI subsystem" 51 depends on NET && ISDN 52 53config ISDN_CAPI 54 tristate "CAPI2.0 support" 55 depends on ISDN 56 help 57 This provides the CAPI (Common ISDN Application Programming 58 Interface, a standard making it easy for programs to access ISDN 59 hardware, see <http://www.capi.org/>.
