If your computer is equipped with an ISDN 14e5f8d9acSTilman Schmidt adapter you can use it to connect to your Internet service provider 15e5f8d9acSTilman Schmidt (with SLIP or PPP) faster than via a conventional telephone modem 16e5f8d9acSTilman Schmidt (though still much slower than with DSL) or to make and accept 17e5f8d9acSTilman Schmidt voice calls (eg. turning your PC into a software answering machine 18e5f8d9acSTilman Schmidt or PABX). 191da177e4SLinus Torvalds 201da177e4SLinus Torvalds Select this option if you want your kernel to support ISDN. 211da177e4SLinus Torvalds 22cf4d5f1dSJan Engelhardtif ISDN 231da177e4SLinus Torvalds 24857038d9SJan Engelhardtmenuconfig ISDN_I4L 255bf1deddSTilman Schmidt tristate "Old ISDN4Linux (deprecated)" 264f73bc4dSJoe Millenbach depends on TTY 271da177e4SLinus Torvalds ---help--- 285bf1deddSTilman Schmidt This driver allows you to use an ISDN adapter for networking 291da177e4SLinus Torvalds connections and as dialin/out device. The isdn-tty's have a built 301da177e4SLinus Torvalds in AT-compatible modem emulator. Network devices support autodial, 311da177e4SLinus Torvalds channel-bundling, callback and caller-authentication without having 321da177e4SLinus Torvalds a daemon running. A reduced T.70 protocol is supported with tty's 331da177e4SLinus Torvalds suitable for German BTX. On D-Channel, the protocols EDSS1 341da177e4SLinus Torvalds (Euro-ISDN) and 1TR6 (German style) are supported.
