If your computer is equipped with an ISDN 13 adapter you can use it to connect to your Internet service provider 14 (with SLIP or PPP) faster than via a conventional telephone modem 15 (though still much slower than with DSL) or to make and accept 16 voice calls (eg. turning your PC into a software answering machine 17 or PABX). 18 19 Select this option if you want your kernel to support ISDN. 20 21if ISDN 22 23menuconfig ISDN_I4L 24 tristate "Old ISDN4Linux (deprecated)" 25 ---help--- 26 This driver allows you to use an ISDN adapter for networking 27 connections and as dialin/out device. The isdn-tty's have a built 28 in AT-compatible modem emulator. Network devices support autodial, 29 channel-bundling, callback and caller-authentication without having 30 a daemon running. A reduced T.70 protocol is supported with tty's 31 suitable for German BTX. On D-Channel, the protocols EDSS1 32 (Euro-ISDN) and 1TR6 (German style) are supported. See 33 <file:Documentation/isdn/README> for more information. 34 35 ISDN support in the linux kernel is moving towards a new API, 36 called CAPI (Common ISDN Application Programming Interface). 37 Therefore the old ISDN4Linux layer will eventually become obsolete. 38 It is still available, though, for use with adapters that are not 39 supported by the new CAPI subsystem yet. 40 41source "drivers/isdn/i4l/Kconfig" 42 43menuconfig ISDN_CAPI 44 tristate "CAPI 2.0 subsystem" 45 help 46 This provides CAPI (the Common ISDN Application Programming 47 Interface) Version 2.0, a standard making it easy for programs to 48 access ISDN hardware in a device independent way. (For details see 49 <http://www.capi.org/>.) CAPI supports making and accepting voice 50 and data connections, controlling call options and protocols, 51 as well as ISDN supplementary services like call forwarding or 52 three-party conferences (if supported by the specific hardware 53 driver). 54 55 Select this option and the appropriate hardware driver below if 56 you have an ISDN adapter supported by the CAPI subsystem. 57 58if ISDN_CAPI 59 60source "drivers/isdn/capi/Kconfig" 61 62source "drivers/isdn/hardware/Kconfig" 63 64endif # ISDN_CAPI 65 66source "drivers/isdn/gigaset/Kconfig" 67 68source "drivers/isdn/hysdn/Kconfig" 69 70source "drivers/isdn/mISDN/Kconfig" 71 72config ISDN_HDLC 73 tristate 74 select CRC_CCITT 75 select BITREVERSE 76 77endif # ISDN 78
