Abstract
A subscriber terminal for ISDN networks in the form of an ISDN telephone (11) is equipped with a keyboard (15,16), a display (14) and a connection socket (19) for another applications terminal (21-24), such as a printer and/or a keyboard and/or a computer, a PC for example. An interface is integrated into the ISDN telephone (11) for the cost-effective connection of an applications terminal, with which the ability to communicate between the applications terminal to be connected (21-24) and the ISDN network, can be established.
Claims25
A subscriber terminal for an ISDN network in the form of an ISDN telephone, comprising:
- at least one telephone keyboard;
- a display;
- a connection socket for connecting at least one application terminal;
- and
- an integrated interface means for establishing communication between said at least one application terminal and the ISDN network through the connection socket, having a non-voice server and a service-independent means for providing direct communication of non-voice information signals between the ISDN network and said at least one application terminal, and having a control device for remotely controlling functions of the ISDN telephone and for transmitting directly information to the ISDN network.
A subscriber terminal for an ISDN network in the form of an ISDN telephone, having at least one telephone keyboard, a display and having a connection socket for connecting at least one application terminal,
- wherein the ISDN telephone includes an integrated interface for establishing communication between said at least one application terminal and the ISDN network,
- wherein the integrated interface has a non-voice server for coupling said at least one application terminal to the ISDN telephone to provide direct communication of non-voice information signals, including text-oriented information signals and graphics-oriented information signals,
- wherein the integrated interface also has a service-independent interface means for coupling the ISDN telephone to the ISDN network for providing telextex and telex services, page-oriented communication services, telefax, and graphics-oriented communications services, and
- wherein the integrated interface also has a control device for remotely controlling the function of the ISDN telephone and for transmitting directly information to the ISDN network.
An ISDN telephone for connecting to an ISDN network, comprising:
- a telephone keyboard for providing text information signals;
- a display for displaying text information signals;
- a connection socket to be connected to at least one external application terminal;
- and
- an integrated interface means having a text-oriented and graphics-oriented information server for providing direct communication of text-oriented and graphics-oriented information signals between the ISDN network and said at least one external application terminal, and for providing direct communication of text-oriented information signals between the ISDN network and the telephone keyboard and the display.
