If your computer is equipped with an ISDN 14 adapter you can use it to connect to your Internet service provider 15 (with SLIP or PPP) faster than via a conventional telephone modem 16 (though still much slower than with DSL) or to make and accept 17 voice calls (eg. turning your PC into a software answering machine 18 or PABX). 19 20 Select this option if you want your kernel to support ISDN. 21 22if ISDN 23 24menuconfig ISDN_CAPI 25 tristate "CAPI 2.0 subsystem" 26 help 27 This provides CAPI (the Common ISDN Application Programming 28 Interface) Version 2.0, a standard making it easy for programs to 29 access ISDN hardware in a device independent way.
