Circuit arrangement for integration of EDP systems in the utilization of telephone systems

A circuit arrangement for integration of EDP systems in utilization of telephone systems connected to a public ISDN or Euro ISDN telephone network, the circuit arrangement comprising a plurality of telephone extensions which are directly connectable to a telephone network selected from the group consisting of a public ISDN telephone network and Euro ISDN telephone network;

• a first line;
• an intelligent telephone system arranged so that said telephone extensions are connectable with said at least one telephone network through said first line and said intelligent telephone system;
• a plurality of personal computers;
• an integration element arranged between said intelligent telephone system and said personal computers, said integration element receiving signals via at least one connection element selected from the group consisting of an SDLC connection element and an ISDN connection element via a second line from said at least one telephone network via said intelligent telephone system and sending back signals to said at least one telephone network, said integration element also sending a data record assigned an appropriate information via a third line, via a LAN connected to a LAN server by a fourth line and via a fifth line to said personal computers and receiving a data record from said personal computers again;
• a computing system;
• and a software layer arranged so that a conversion of the signals into a data record and vice versa is carried by said integration element, by said computing system, by said software layer and by said at least one connection element with an internal software.
