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 depends on TTY 26 ---help--- 27 This driver allows you to use an ISDN adapter for networking 28 connections and as dialin/out device. The isdn-tty's have a built 29 in AT-compatible modem emulator. Network devices support autodial, 30 channel-bundling, callback and caller-authentication without having 31 a daemon running. A reduced T.70 protocol is supported with tty's 32 suitable for German BTX. On D-Channel, the protocols EDSS1 33 (Euro-ISDN) and 1TR6 (German style) are supported. See 34 <file:Documentation/isdn/README> for more information. 35 36 ISDN support in the linux kernel is moving towards a new API, 37 called CAPI (Common ISDN Application Programming Interface). 38 Therefore the old ISDN4Linux layer will eventually become obsolete. 39 It is still available, though, for use with adapters that are not 40 supported by the new CAPI subsystem yet. 41 42source "drivers/isdn/i4l/Kconfig" 43 44menuconfig ISDN_CAPI 45 tristate "CAPI 2.0 subsystem" 46 help 47 This provides CAPI (the Common ISDN Application Programming 48 Interface) Version 2.0, a standard making it easy for programs to 49 access ISDN hardware in a device independent way. (For details see 50 <http://www.capi.org/>.) CAPI supports making and accepting voice 51 and data connections, controlling call options and protocols, 52 as well as ISDN supplementary services like call forwarding or 53 three-party conferences (if supported by the specific hardware 54 driver). 55 56 Select this option and the appropriate hardware driver below if 57 you have an ISDN adapter supported by the CAPI subsystem. 58 59if ISDN_CAPI 60 61source "drivers/isdn/capi/Kconfig" 62 63source "drivers/isdn/hardware/Kconfig" 64 65endif # ISDN_CAPI 66 67source "drivers/isdn/gigaset/Kconfig" 68 69source "drivers/isdn/hysdn/Kconfig" 70 71source "drivers/isdn/mISDN/Kconfig" 72 73config ISDN_HDLC 74 tristate 75 select CRC_CCITT 76 select BITREVERSE 77 78endif # ISDN 79
