| 10 | ISDN ("Integrated Services Digital Network", called RNIS in France) |
| 11 | is a fully digital telephone service that can be used for voice and |
| 12 | data connections. 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. |

| 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. |

| 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. |
