ISDN consumer device

All terminal devices that have an S0 interface are ISDN-capable. Older terminal devices that were used on the analoguetelephone network or in the Datex networks can be connected to the S0 interface via terminal adapters.

Devices for the analogue telephone network such as telephones, modems, fax machines of group 2 and 3 have a/b interfaces. In addition, there are data terminals with V.24 interfaces. Data terminals for the Datex networks have the X.21 interface (Datex-L) or X.25 for networks with data packet switching. All these terminals become ISDN-capable terminals via corresponding terminal adapters that are connected directly to the S0 bus.
