The main advantage is that the speed is higher than ordinary 16 modem/telephone connections, and that you can have voice 17 conversations while downloading stuff. It only works if your 18 computer is equipped with an ISDN card and both you and your service 19 provider purchased an ISDN line from the phone company. For 20 details, read <http://www.alumni.caltech.edu/~dank/isdn/> on the WWW. 21 22 Select this option if you want your kernel to support ISDN. 23 24 25menu "Old ISDN4Linux" 26 depends on NET && ISDN 27 28config ISDN_I4L 29 tristate "Old ISDN4Linux (obsolete)" 30 ---help--- 31 This driver allows you to use an ISDN-card for networking 32 connections and as dialin/out device. The isdn-tty's have a built 33 in AT-compatible modem emulator. Network devices support autodial, 34 channel-bundling, callback and caller-authentication without having 35 a daemon running. A reduced T.70 protocol is supported with tty's 36 suitable for German BTX. On D-Channel, the protocols EDSS1 37 (Euro-ISDN) and 1TR6 (German style) are supported. See 38 <file:Documentation/isdn/README> for more information. 39 40 ISDN support in the linux kernel is moving towards a new API, 41 called CAPI (Common ISDN Application Programming Interface). 42 Therefore the old ISDN4Linux layer is becoming obsolete. It is 43 still usable, though, if you select this option. 44 45if ISDN_I4L 46source "drivers/isdn/i4l/Kconfig" 47endif 48 49endmenu 50 51comment "CAPI subsystem" 52 depends on NET && ISDN 53 54config ISDN_CAPI 55 tristate "CAPI2.0 support" 56 depends on ISDN 57 help 58 This provides the CAPI (Common ISDN Application Programming 59 Interface, a standard making it easy for programs to access ISDN 60 hardware, see <http://www.capi.org/>.
