Description

Circuit arrangement for billing with call slip printer in international remote dialing operations The invention is used to prepare a fee slip in automatic international traffic. At the request of the calling subscriber, a slip printer should be used be connectable to the connections. The individual call charge recording should proceed in the same way as the summary count during the conversation.

There is a single call charge recording in international dialing traffic keen interest for several reasons. Once the participant wants a receipt for the high fees incurred in international transactions, if necessary for foreign exchange settlement. On the other hand, the participating countries are also in receipt of receipts for billing Interested. Finally, the one-on-one charge slips allow statistical data Traffic surveys.

A major problem with all one-to-one billing systems consists in the implementation of the subscriber identification. In domestic dial-up traffic if one is satisfied with the recording of fees by means of a summary count. It seems therefore unsustainable because of the comparatively low proportion of international dialing traffic to set up separate identification circuits for the entire traffic volume.

For domestic traffic has already been proposed, with involvement an officer in a calling party as desired, which z. B. by choosing special Key figures can be printed out, a call slip printer is available to deliver. The mediation officer should not take longer than to establish the connection required. To implement this procedure would have to the key figures are transferred back from the main office to the node office, because the The express traffic area and the slip printer are in the main office, the counting pulse generator for the automatic billing, however, housed in the node office.

The conversation slip, which is only used for supporting purposes, on the other hand should not be used as a basis for the billing, can be done by keying the code and number to be given by the calling subscriber. This procedure is possible because the calling party himself is the right one Issuing the interview slip is interested and has no way of getting through false information to evade the fees.

With fully automatic dialing of a subscriber in international long-distance dialing mode become a foreign; counting pulse generator and a foreign billing meter showing the Ensure automatic billing, connected to a connection. Of the Foreign counting pulse generator must generate the time-dependent counting pulses with carrier frequency or Enter audio frequency back into the domestic counter, where it is in the domestic are passed on to the calling subscriber's counter in the usual way.

From the start of the conversation, the counting pulses sent by the foreign counting pulse generator to the calling subscriber and to the slip printer. At the end of the conversation or at a desired time during the same would have to be the date and time of day to be printed. After keying in the code of the calling subscriber to exit the connection in the slip printer, so that they are no longer switched on when the called subscriber reports needs to be.

The solution to the problem is that in international remote dialing systems, in which automatic charging takes place in self-dialing traffic and the same An officer with the necessary language skills switched on the connection can be, under the influence of a special requirement number to be chosen by the participant according to the country code in the decade in which between automatic selection and A distinction is made between connection of intercom stations, switching means become effective, which enables a slip printer to be connected to the international connection cause and also an operating device or automatic switching means for Determination of the number of the calling party without special Switch on the identification device.

This inventive concept can be designed in such a way that after choosing a special request identifier, an announcement device for the connection is switched on, by which the participant is requested, in quick succession to choose his identification number and subscriber number, and that special switching means this Conduct power surges into a slip printer. At the end of the number chosen by the participant and call number, a dialing pause must be inserted through which the end of the dialing process can be recognized is made. It can be ensured that the participant is about 3 Seconds pause or z. B, dials a specific digit three times.

The special circuits for connecting the slip printer and the Schnellverkehrsplatz can be arranged in the international counter.

An embodiment of the invention is explained with reference to the drawing. 1 shows a voter overview plan for the integration of the slip printer and the Schnellverkehrsplatz, Fig. 2 Excerpts from the circuits of the foreign counting pulse generator with details of the additions for the connection of the slip printer and the express traffic station.

In Fig. 1, a dial-up connection for international traffic is shown. Coming from an end office, the connection runs through a node office 1 and a Main office 2 into a foreign central office 3, where the connection is finally via a Long-distance line 34 opens into a line of the desired bundle. Via an end office line 5 and an incoming transmitter 4, the connection is routed to the node office 1, where a counting pulse generator 6 is connected to the connection. Through this pulse generator a voter 7, e.g. B. a relay search selector to connect a zoner 8 caused. With the help of the above-mentioned facility, the domestic connections are controlled and zoned. A node trunk direction selector 9 is used to set the various Cross paths as well as the key figure path. A outgoing transformer 10 occupied, which at a hybrid circuit 11 the transition from two-wire to four-wire technology.

A four-wire line 12 is available as a node exchange line for the connection to disposal. The entrance to the main office is via an incoming transformer 13 2 occupied. Here, if necessary, a reversing selector, not shown, is interposed a connection set 14 reached, which has a relay search selector 15 and a Main office memory 16 is controlled. From this connection set 14, the key figures for setting the main office direction selector 17 transferred to a setting set 18. By dialing the number 00, the latter is prompted to use a code number via a Select connection line 19 to the Central Office for Foreign Traffic, which via a transmission 20, a four-wire channel 21 and an incoming transmitter 22 the Central Office is occupied. The number 0 to which the zone group selector 23 is set causes the selection of an exit to the international part of the voting facilities, namely first a foreign counting pulse generator 24 is occupied, which has a Relay seeker 25 sets a foreign zoner 26. This zoner 26 causes now via an adjuster 31 and a foreign direction selector 32 the assignment an outgoing transmitter 33 and a line 34 from the bundle of transmission channels, those from the head international central office to the destination central office of the elected Country lead.

In the case of fully automatic call processing, the zoning machine 26 transmits the code number of the foreign zone to the foreign counting pulse generator 24. Thereupon, the time clock of the relevant zone is set by the zone memory of the foreign counting pulse generator 24. Furthermore, counting pulses are transmitted to the calling subscriber line at the time intervals corresponding to the distance. These tone-frequency counting pulses run inaudibly back into the exit node office 1 and reach the counting pulse generator 6, which has stopped its internal activity due to the selected international code and instead takes over the counting from the international counter.

For a connection z. B. to Vienna is in the exit zoning 26 the to evaluate the country code 23 chosen by the participant. Before within the Austrian Network code 222 valid for Vienna is either the number 0 for the fully automatic Traffic or the numbers 1 to 8 to connect an officer to a specific Language is able to choose. Eight different language codes can be considered sufficient can therefore be viewed according to the invention, the number 9 for the slip request be used.

So if the caller chooses the national number after dialing 00 23 Code 9 dials 222, this means for the zoner 26 that a call slip it is asked for. A printer 28 becomes this via a further relay search selector 29 Purpose connected to the foreign counting pulse generator 24. For the domestic counter 6 the above number sequence means that the counting pulses from the foreign counting pulse generator should be sent.

The calling subscriber can be identified via a rapid transit point 27, which is sent to the counting pulse generator 24 via a further search selector 30 is switched on. There is also the possibility that the relay search selector 35 the slip printer 28 (shown in dashed lines) rides the express traffic area together 27 turns on. The Schnellverkehrsplatz 27 should after keying in the last digit emerge from the connection in the slip printer 28. In contrast, the slip printer should 28 or at least its data memory is used for the entire duration of the connection stay. For connecting on the one hand the slip printer 28, on the other hand the express traffic station separate search selectors 30 and 29 are switched on.

The embodiment of FIG. 1 was made using structural units the so-called four-wire transmission technology. However, it means for the application of the present inventive concept does not change if instead the full technology is used. In the latter case is known to be in '' office over a relay search selector 7 to turn on a code memory 8, which in turn for the conversion processes use a relay corrector for the entire office is common. The main office store is also located in Office 2 16 through an electronic corrector supports the stored key figures returns encrypted in the code memory 16. The key figure memory can evaluate the key figures via the setting set 18 to operate the relay search selector. Also in office 3, the foreign central office, the zoner 26 would be a foreign code memory, that works with an electronic corrector.

It is essential for the circuit according to the invention that through the choice a special code, which in this example takes the place of the language code is given, the incentive to connect the ticket printer device28 of the Schnellverkehrsplatz 27 takes place. The code memory 26 is useful when the international code is passed on this at the same time either transferred to the slip printer 28 or held for this. This means that all of the information required to establish a connection is stored on the called party in addition to the information for establishing a connection for the slip printer 28 is provided. Is this slip printer 28 set up so that it digit by digit with a type wheel prints and always goes to the zero position between the successive digits, in this way he can briefly take the imprint while the current impulses are being passed on. The involvement of the express traffic officer must not interfere with the election. The officer only has to find the opportunity until the called subscriber reports the number of the calling subscriber and this code in the code memory 26 or directly into the slip printer 28.

It is now necessary to switch on the express traffic area Force 27 at the right time. Neither the message of the called nor the choice of the calling subscriber will be disturbed. The last election digits run for example via a pulse repeater. It can also be thought of to stop the transmission of the dialing impulses until the conversation between the officer and the calling subscriber is complete, provided the number of digits to be saved Digits is so high that only one or two digits are missing from the subscriber number.

The inclusion of the calling code and the subscriber number means unpaid, extended use of the liaison bodies. Otherwise a special fee would have to be provided for the issue of the slip. It must therefore Be sure that those administration compensated for that through a note fee will also bear the burden of the connection extension alone. It must be avoided that on the international lines the time of identification of the calling party and the Keying in the calling number into the slip printer appears as a dummy assignment.

After in the outgoing facility with routing again In principle, the entire electoral information is stored, is the impulse transmission after saving the number 9 at a point in time where none of the country code has yet been added corresponding outgoing line is busy, stop and connect the officer to make it effective. At the same time, the connection of the slip printer was already at Storage of the sequence of numbers 23 9 initiated.

The further processes are described with reference to FIG. Here, of the elements of the foreign central office 3 according to FIG. 1, the transformer 22 is shown with its outputs at the top left. Furthermore, the eight arms of the zone group selector 23, the routing of the speech lines and the control lines through the international counter and finally the circuit parts of the international direction selector 32 and the inputs to the transmitter 33 that are essential for the circuit according to the invention are shown. A relay search selector RSW 1 for connecting the foreign zoner AVZR to the foreign counting pulse generator AZIG, a relay search selector RSW 2 for connecting the express traffic station SPl and a relay search selector RSW 3 for connecting the slip printer ZDr are shown under the foreign counting pulse generator. The corresponding organs are denoted by the numbers 27 to 30 in FIG. Only those circuits are executed which are necessary to explain the principle of the switching arrangement according to the invention. It should be emphasized that instead of a foreign zoner, a digit memory can just as well be used, which works together with an electronic or a relay corrector. The corresponding processes are then correspondingly the same.

The voice lines run between the two transmissions ük and 1`Jg four-wire. Assuming an eight-armed zone group voter ZGW and a similar one Direction selector ARW, there are four control lines in addition to the speech lines.

The incoming transformer assigns a free foreign counter AZIG to the zone group selector ZGW via the c-core. The e-vein is only carried out for the sake of simplicity. The dialing pulses sent by the subscriber and converted by the transformer Ük are transmitted via the d-wire to the Zonenzählirn pulse generator ZIG, via this to the relay seeker RSW 1 and via its z- and e-contact to the pulse relay A of the international zoner AVZR. Via contacts of relay A, the dialing information is stored in the memory of the zoner, which serves the double task of zoning and routing. Feedback from the end of the line to the beginning of the line, in particular to the counter pulse generator for national traffic, is sent via the e-wire. The counting pulses sent at the timing are guided to the transmitter ük supplied via the f-artery, it passes over a Tonfrequenzkanal or in another conventional method for today Zählimpulsgeber and further to the subscriber counter.

With the assignment of the foreign counting pulse generator by dialing the number 0, the relay search selector RSW 1 is prompted to switch on a foreign zoner AVZR immediately after the assignment relay C has responded. The subscriber's dialing pulses are then fed to this. The contact a 1 directs the counting pulses via a decade control chain u 1 to u 5 into the storage organs. These consist, for example, of a lifting magnet H 1 (operated by the number 2 of the country code) and a rotary magnet D 1 (operated by the number 3 of the country code), as well as a selector relay W (the number 9 is stored when a call charge slip is requested, storage the number 0 if the participant is satisfied with the summary count). The number of digits corresponding to the digits 2 and 3 of the national code are stored in the converter for zoning and then get into a pulse repeater 1W with the last power surges of the subscriber number.

In Fig. 2, the double evaluation is only shown in one symbol each: on the left, the outputs of the zoning contact banks lead to the ten to twelve step Zone tap ZA, which has the contact to and an arm of the relay search selector RSW 1 transfers the zone to the ZE zone setter. This switches over the arm Ze the counter relay Z to the clock generator ZT for the foreign zones. As already stated, the pulses are fed back to the counting pulse generator via the f-wire.

To the right of the storage organs it is indicated that the tapping of the Stored information causes traffic to be routed. The information for the further choice is picked up by a transmission relay S and with a contact s via the d-arm of the international direction selector ARW is directed to the outgoing transformer. It can be given in a pulse dialing or in a single or dual frequency code.

The arm w causes a call slip relay G to be excited by setting it to a contact. This ensures the immediate connection of a slip printer ZDr and a call set at the express traffic station SPI. The officer enters the connection and hears acoustic signals whether the participant is taking a break after dialing number 9 or choosing the world. In the first case, she speaks immediately to the subscriber and has him give her the code and the number called, which she keyed into the slip printer ZDr with a selection key WT, namely into its pulse receiving relay IM . Then she actuates the end key ST. After expiration; On the keyboard, the express traffic station SPL also switches off from the ZDr slip printer. The subscriber can now continue his choice or, if he has already dialed completely, he can wait until the national code and the code of the called subscriber have been sent from the routing memory via the outgoing transmitter Üg. At the end the free signal sounds.

The express traffic area SP1 was separated from the relay search selector RSW 2 by pressing the closing button ST. Via a toggle contact q, the incoming impulses from the beginning of the connection are activated on the impulse relay of the note printer.

The arrangement can also be made so that the participant only dials the country code and the number 9 and, as with the dual operating system, the Destination within the distant country and the participant number of the express traffic officer notifies. This would have to convert the place name into a code and then Key in the desired subscriber number into the ZDr slip printer. If the first digits of the national code are still important for zoning, so they can be taken into account in the foreign zoner AVZR. There is no reverse transmission for this of key figures required.

This solution to this organizational question is only indicated in the symbol. The organizational question is essentially whether you can follow the participants number 9 cancels the election or not. In the former case, namely the contact a 2 the further -incoming dialing impulses in the slip printer ZDr; just. In the latter case, if the participant is allowed to dial the total number, so this is to be saved and it is the job of the contact or a second one tapping organ, not shown, the dialing pulses sent to the country of destination to be put into the ZDr slip printer at the same time.

It is possible to equip the ZDr slip printer with two printing units. The keying in of the officer can then simultaneously with the forwarding of the dialing information of the call.

A modification of the arrangement according to the invention is possible in the sense that that after choosing number 9, not an express traffic place, but an announcement device is switched on, which asks the participant: »Select the code of your Local area network and your own subscriber number if you receive a call slip want. «If the participant dials the mentioned digits in response to the request, so is under the influence of a selector relay WR, which responds to the number 9, this Digit not saved for connection establishment; but only the slip printer forwarded.

One difficulty with the process is the end of the election ascertain. Because after the end of the choice of his own code, the participant must continue the international election. One solution could be that the participant E.g. after dialing his number, dial 1 three times or take a pause from inserts for about 3 seconds. In any case, the intercom must have a distinguishing feature to provide. Upon receipt of the end code, the facility could give the participant the instruction: "Please continue dialing."
