The main advantage is that the speed is higher than ordinary 161da177e4SLinus Torvalds modem/telephone connections, and that you can have voice 171da177e4SLinus Torvalds conversations while downloading stuff. It only works if your 181da177e4SLinus Torvalds computer is equipped with an ISDN card and both you and your service 191da177e4SLinus Torvalds provider purchased an ISDN line from the phone company.

The isdn-tty's have a built 331da177e4SLinus Torvalds in AT-compatible modem emulator. Network devices support autodial, 341da177e4SLinus Torvalds channel-bundling, callback and caller-authentication without having 351da177e4SLinus Torvalds a daemon running. A reduced T.70 protocol is supported with tty's 361da177e4SLinus Torvalds suitable for German BTX. On D-Channel, the protocols EDSS1 371da177e4SLinus Torvalds (Euro-ISDN) and 1TR6 (German style) are supported.
