The subject of the main patent application is a process for the central registration of fees in Teleprinter systems in which the IDs of a connection are requested from a central point and as Parallel combinations are fed to a central identifier S multiple field, which is characterized is that via a central, connected to a multiple identifier field, the identifiers are received Switching means and a switching folder, the connecting members requesting a connection successively caused to give the identification on the central multiple identifier field, from where the identifier characterizing a connection at the start of the connection together with a date and Identifier indicating the time and a channel identifier identifying the selected connection channel arrives in a first central memory that in each case after the storage of those that arrive at the beginning of the connection in the first central memory Identifiers for later recording of a further identifier characterizing the ao connection sufficient space is kept free and that in optionally adjustable time intervals the in the first Memory contained identifiers either directly or via a buffer in a second central Memory with a compared to the first memory larger storage capacity can be transferred.

The data required for a fee assessment and the fee calculation are recorded at a central point. It is possible to assign the fees of a participant individually record and, for example, create a separate billing slip for each connection, but there is no way to charge the subscriber for this connection at the end of the connection attributable to.

This disadvantage is eliminated by the invention. A possibility is created at the request of the assigning the calling party the charge for a connection at the end of the connection. The invention is based on the idea given in the main patent application, which Transfer of the charge data from a first central memory to a second central memory via a computing device in which either the charge is determined directly from the identifiers or converted into a form that is advantageous for calculating the fee.

The invention is characterized in that for the automatic charge feedback to the calling subscriber at the end of a connection, a charge feedback triggering criterion on the Ver method and circuit arrangement

The beginning of the connection is given in a channel identifier and stored there until the end of the connection and that this criterion is only entered into a first memory once at the end of the connection and there the immediate forwarding of the data required for the fee assessment in a Computing device causes and that on the other hand depending on this criterion at the end of the connection a central charge allocation register is connected to the link via a coupling device will.

The criterion that triggers the sending of charges can either be made by the subscriber himself - for example by means of a preselection digit - sent or becomes - cannot be influenced by the subscriber - through the subscriber circuit is sent with each occupancy. In the second case it should be noted that the fee attribution takes place automatically for the respective subscriber after each connection.

Further details of the invention are based on the circuit arrangement shown in the drawing explained.

There is shown an arrangement for teleprinter systems for central billing and billing, as already described in the main patent application. For the case described below, it should be assumed that the criterion that triggers the sending of charges is sent by the calling subscriber. This criterion, for example a specific number, reaches the channel identifier KGK and is stored there until the end of the connection. The central coupler ZK switches the

Channel identifier KGK on a free link VG . When the connection element VG is called up by the central switch folder SO , the connection identifying codes arrive in the manner described in the main patent application via the central identifier Md'KV in, a receive register ER and a write amplifier SV1 in the first memory FS. Then the connection is released via the coupler ZK . However, the route from the subscriber to the connection channel remains. After the end of the message exchange, the channel identifier KGK is again prompted to connect to a free link VG via the central coupler ZK . In addition, as described in the main patent application, the link VG also controls the date-time transmitter DZG so that its information reaches the reception register ER of the central first memory FS via the central multiple identifier field KV vx. Together with these identifiers, the criterion which triggers the sending of charges also arrives in the memory FS and there causes both the identifiers which characterize the connection and the criterion which triggers the sending of charges to be sent immediately via a buffer memory PJ? a computing device ZZR are fed. The connecting element VG in turn connects to a charge writing register GZR via a further coupler GZK .

Since the re-storing from the first memory FS in the second memory BS is initiated as soon as the charge information are complete, is immediately at the end of message in the buffer PR is arranged Recheneiniichrung nper that a time-zone calculator is, for example, the zone and the resulting charge determined. The immediate re-storage of the charge data contained in the first memory FS in the computing device ZZR assigned to the intermediate memory PR is brought about by the criterion which triggers the sending of charges.

From the computing device ZZR , the calculated result is returned to the buffer PR , from where the parts of the result that are eligible for a charge report are transferred to the ■ charge writing register GZR , whose output is connected to the link VG via the coupler GZK . The transfer from the buffer PR to the charge writing register GZR takes place in parallel. At the same time, those in the buffer Fi? standing total charge data passed to the second central memory BS , where they are available for later data processing (for example, billing).

A parallel-serial converter PSZ7 is assigned to the charge- writing register GZR, which has the purpose of assigning the charge present in parallel form to the calling subscriber via the still existing So connection in series. It is of course possible to design the speed of the parallel-to-serial converter PSU so that it can be switched over.

After the broadcast has ended, the connection is completely disconnected. At the same time, the couplers ZK and GZK are triggered and thus the connection element VG and the charge writing register GZR are enabled again. '
