Description

GERMAN

In the telephone system !! it is known to the participants Individually assign fee counters, which are given by the public office, in a Exchange incoming charge pulses are forwarded. Switching takes place if the counters are arranged at the subscriber station, via the speech wires, if they are central or in the Subscriber circuit are provided via pilot wires or special switching mechanisms.

Since separate collection of local and long distance charges is generally desirable are are separate in different known arrangements for the different types of calls Participant counter provided. The latter must then because of the different labeling controlled via pilot wires. For the most part, only a single pilot wire is required for this.

In the known arrangements, the counters are operated via the individual office transfers individually assigned voters who are tuned to the participant who is responsible for the charges are. In smaller private branch exchanges, the exchange dialer can be used for this purpose Find. So z. B. used a special switching arm set in a known arrangement. To this effort To avoid special switching arm sets, it is not known to use one that is already used for other purposes Switch arm ,, z. B. to use a test arm also for counting, which, however, entails additional effort at least one common, special voltage source and the participants as well as the Office transmissions of individually assigned blocking switching means is required. In larger private branch exchanges on the other hand, in the known arrangements, the incremental switching of centrally arranged charge meters only via special switching means that are individually assigned to the trunk transmissions possible.

The cost of individual switching means was l> ei said known arrangements, as ¹ large that passed in telephone PABXs for automatic billing using a Identinzierungseinrichtung for subscriber identification. Automatic billing with subscriber identification is to be understood here and in the following as billing in printing facilities.

Automatic billing in private telephone exchange systems generally only extends to a detailed determination of the for a Long distance call characteristic data. The local calls, however, are lump-sum to the officially authorized Extensions transferred. The charges for local calls as well as charges for S ctialing arrangement

Printing long-distance calls or putting them on punch cards is not economically justifiable because the The cost of the evaluation is between 10 and 30% of the cost of a local call. On the other hand, the share of local call charges is generally between 40 and 80% of total telephone charges, automatic billing must also include local call charges offsetting proportionally to the participants or cost centers causing them.

The aim of the invention is to provide an arrangement that allows for local call charge registration relatively little effort compared to the facilities of telephone registration in in a satisfactory manner. This is achieved through a common transfer of office, the breakdown of local call impulses arriving in the latter to subscriber stations and / or local calls counting pulse couplers serving cost centers and / or monitoring centers, under the influence of one

Identification device determined identification result is controlled.

If the local call charges are broken down to subscriber stations with an arrangement according to the invention and, for example, counters assigned by the authorized subscriber added, there is compared to known arrangements in which the participants in the Subscriber circuit or charge counters arranged at the subscriber station itself are assigned, the advantage of easier readability of the counters, since the counters of all participants are arranged centrally can be. Special wires parallel to the speech wires of the connection lines for transmission the counting pulses to the subscriber circuit or individual switching means for multiple use of test leads for the stated purpose or charge switches at the subscriber stations are not applicable.

In the case of an arrangement according to the invention, they are replaced by several or all transfers of office jointly assigned coupler, via which by a single relay winding (relay coupler) or to a cross point of two coils (cross-coil coordinate selector) actuatable contacts according to further Training of the invention are assigned to several participants and corresponding to the participants Prepare circuits for counting or monitoring, one of which is through contacts of the Identification result recording switching means of the identification device, a memory, marker is selected. For example, a coupler is used that enables four-wire through-connection and has 25 crosspoints, 100 subscriber counters can be used via this coupler be advanced.

The use of the coupler is not limited to the operation of subscriber counters. it can be done simultaneously with the latter or independently of the presence of the latter cost center counter and / or monitoring switching means are controlled, the latter of which, for example, the monitoring of a subscriber or an external call number frequently dialed by a subscriber.

In the latter case, the arrangement can expediently be made in accordance with a further embodiment of the invention that depending on a controllable via the local call counting pulse coupler Monitoring relay and depending on the one making a local call Subscriber dialed number to a character corresponding to the monitoring result the printing device assigned to the private branch exchange is transmitted.

Instead of counters assigned to the individual subscriber stations or at the same time as the latter Cost center relays assigned to the individual cost components can also be influenced via the coupler, the character corresponding to a cost center of a subscriber conducting a call to the Transfer the printing device assigned to the private branch exchange.

The local call counting pulse coupler used in an arrangement according to the invention thus represents an element that can be used several times, the expense of which is compared to that for the acquisition of the Long-distance call charges hardly matter.

Various exemplary embodiments of the invention are shown in the drawings.

1 to 4 show block diagrams of four exemplary embodiments,

Figures 5 and 6 show in detail a coupler according to the invention.

The block diagrams each show an exchange transmission AUe with a memory ESp for storing the external call number and a memory JSp for storing the internal call number. These memories can be assigned to the exchange transmission individually or jointly with several exchange transmissions and, if necessary, connected to the latter. The external call number is recorded by the memory ESp when an exchange connection is set up by an extension subscriber, while the internal call number of the subscriber setting up the exchange connection is determined by the identification device JE.

The values characteristic of a long-distance connection (internal call number, external call number, number of incoming charge pulses) are transmitted to a printing device DE after the long-distance call has ended, which is under the influence of a printing control device DSt .

If there is a charge imp'Ulses received for a local call in an exchange transmission, the local call counting impulse coupler OK, which is jointly assigned to the exchange transmission, is requested by the latter and in accordance with the information determined by the identification device JE and. set in the memory JSp cached internal call number. The coupler can be under the influence of a marker M (Fig. 1 to 3) and / or can be used via a test multiple PVF (Fig. 4). However, it is also conceivable that the identification does not begin until the connection is terminated and after the counting pulse has arrived , so that the buffer JSp and, if the identification device JE is designed accordingly, also the marker M can be omitted. If the identification result is available, the coupler OK is then controlled directly by the identification device.

In the exemplary embodiment according to FIG. 1, a subscriber counter TZ assigned individually to each authorized extension subscriber and also a cost center relay KR common to a plurality of subscribers are actuated via the coupler OK. The latter influences the print control DSt of the printing device DE directly or via a cost center device KE in a manner corresponding to the cost center result. For the settlement of the fees z. B. the result recorded by the printing device is used, while the counters individually assigned to the subscribers represent a control option in cases where, for example, particularly high fees have accrued for a certain cost center and it is to be determined who caused them. The participant counters can therefore be omitted altogether and can only be permanently or temporarily assigned to individual participants for control purposes. In parallel with the cost center relays, cost center counters can also be arranged to record the incoming charge pulses for local calls, while the cost center relays are only influenced after a long-distance call has been terminated and transmit a character corresponding to the cost center to the printer.

In addition to the subscriber counters, TZ

and / or the cost center relay KR a monitoring relay UeR (Fig. 2) is provided for certain subscribers, which controls a monitoring device Ue, which is simultaneously under the influence of the external call number, when responding. The monitoring device can, for example, depending on the external. Call number establish the catch state and switch on a signal at the branch office officer's place or arrange for a printout of the data characteristic of the local call, in particular the internal call number.

If only a certain state is to be monitored within a private branch exchange, e.g. B. the state: Subscriber has dialed an illegal number, a special monitoring relay can be dispensed with and a monitoring device Ue can be connected directly to the outputs of the coupler OK assigned to the subscribers to be monitored. An embodiment of this kind is shown in FIG

The control of the monitoring device can now also take place independently of the presence of a counting pulse in such a way that after dialing an unauthorized number, which is determined, for example, by a blocking follower assigned to the exchange transmission, the setting of the coupler OK to the subscriber assigned to the blocked number dialing The output of the coupler is OK . The path established by the coupler OK can then be used to influence the normal path. Subscriber counters and / or cost center counters serving power surges, weakened current surge or a current surge in the opposite direction of current are given, which only affects the monitoring device.

With rushes of different amperage can also be used in the example of Fig. 1, if after establishing a long-distance connection only the cost center relay KR is to be influenced, so that even with long-distance calls, in which, yes, the subscriber counter TZ may not be switched on, a division of the charges for long-distance calls according to cost centers and a corresponding printout in the printing facility can be made possible.

On the other hand, it is conceivable that the cost center relay KR of FIG. 1 is only to be influenced for long-distance calls and the subscriber counter TZ for local calls. In the latter case, in which the allocation of the local call charges to the cost centers can then be carried out by cost center counters connected downstream of the subscriber counters, it is advisable to work with power surges in different current directions for the various operating cases (termination of a local call, termination of a long-distance call). The cost center relays KR would then have to be arranged parallel to the subscriber counters, specifically one cost center relay for several subscribers.

Another embodiment of the invention is shown in FIG. 4, in which the local call coupler is under the direct influence of the memory JSp and is requested from the exchange transmission via a test multiple PVF. In the embodiment according to FIG. 4, instead of subscriber counters, only cost center counters KZ are provided, which can of course be influenced in connection with cost center relays KR or monitoring relays UeR.

As already stated, FIGS. 5 and 6 show a detailed representation of a coupler OK according to the invention, which is under the influence of a marker M or under the direct influence of the memory (JSp) for the internal call number. When using a special marker M, it can be omitted if the storage of the call number in the memory (JSp) is carried out in a manner necessary for marking the setting of the coupler, the marker is either under the influence of the memory JSp or under the direct influence the identification device (/.E). Of course, direct control of the coupler from the identification device should also be considered; the latter, however, only if the identification of subscribers making local calls is only initiated when a local call counting pulse is present in an exchange transmission.

For the description of the arrangement shown in FIGS. 5 and 6, it should be assumed that the coupler OK is under the influence of a marker M and the latter is under the influence of a memory JSp for the internal call number. The devices M and JSp are denoted in FIGS . 5 and 6, which are to be placed next to one another, with the corresponding identification letters which are not put in brackets.

The contacts ei 1 to ei 10, di 1 to di 10, hi 1 to AiIO are memory contacts of the memory JSp which temporarily stores the internal call number, the contact an (FIG. 6) is a starting contact and the contact si is a contact that is closed when there is a counting pulse in the exchange transmission to which the memory JSp is assigned. The mentioned memory contacts can, however, also be contacts of the identification device; in order to express this in the figure, the designation JE was placed in brackets after the designation JSp . In the last cases considered, the contacts si and an would also be contacts of the identification device, of which the former would then be closed when the identification result is available and the latter when the time for the transfer of the counting pulse occurs.

The relays El to ElO, Dl to DlO, JiI to iilO (Fig. 5) are marker relays of the marker M and are used to influence the coupler OK and to select a circuit, several of which are prepared at the same time via the coupler. The relays mentioned can just as well be in the memory JSp which is used to store the internal call number, which is why the designation JSp has been added in brackets after the designation M in FIGS. 5 and 6.

As already stated, only the designations that are not in brackets are intended for the further description be taken as a basis.

After the identification of a subscriber making an exchange call has ended and the identification result corresponding to the call number of this subscriber has been transferred to the memory JSp , the memory contacts corresponding to the call number are closed in the latter. It should be assumed that the identified subscriber has the call number 112, so that the contact hi 1 corresponding to the hundreds digit 1, the contact dil corresponding to the decade digit 1 and the contact ei2 corresponding to the units digit 2 are closed in the memory JSp. After a counting pulse has entered the office transmission, the contact si is also actuated at a suitable moment, whereupon the relays Hl, Dl and £ 2 respond. About the con-

cycles 1 h 1 and 1 d 1 of the relays H 1 and D 1, the coupling relays Zl, Z6, ZIl, Z16 and Z21 of the coupler OK are switched on. Via the four contacts lsi to 4.31, ..., Is 21 to 4s21 of each of the coupling relays Zl, ..., Z21, circuits for subscriber counters (TZ), cost center relays (KR), cost center counters (ATZ) and / or monitoring relay (UeR) prepared. In total, there are 20 power circuits, of which ten are selectable via the contacts 2 d 1 to 2 "210 of the decade relay Dl to DLO, of which again a selectable, via the contacts IeI to Ie 10 of a relay El to £ 10th In the example chosen for a telephone number (112), the contact 2 dl of the relay Dl and the contact Ιέ? 2 of relay £ 2 closed.

Upon the occurrence of the time for delivery of a current pulse to the subscriber count, cost centers, relays, etc. of the contact to be closed and hence the earth to the windings of the Participant counter TZ 12 and the cost center relays KR 21 of the cost center is turned on, the attribute the fees caused by the subscriber with the number 112 are.

The contact sf, which is in the circuit of the subscriber payer TZ12 and the cost center relay KR 21 and shorts the resistor W, is a contact of a relay that is excited when counting pulses are received while a connection is in place. As is well known, counting pulses only come in on long-distance connections during the existence of a connection, while with local connections the counting pulse is given at the end of the call. Thus, the resistor W is only effectively switched into the circuit of the subscriber counter and cost center relay for long-distance calls. The arrangement is now made so that the cost center relay always responds, regardless of whether the resistor. W is short-circuited or not, while the subscriber counter can only be advanced if the resistor is short-circuited.

The cost center relay is with several, z. B. four contacts kr equipped, via which a number corresponding to the cost center can be transferred to the printing device of the private branch exchange. The monitoring relay UeRIl is also equipped with several contacts, which enable the transmission or printing of a multi-digit monitoring code. The monitoring relay UeR 11 is switched on, for example, when the participants 152, 172. . . made a local call.

For the purpose of separating parallel circuits which, with simultaneous connection of cost center and Monitoring relays to the subscriber counter are expediently rectifiers in the jumper wiring between the said relays and the meters.

Corresponding to the various possible embodiments of an arrangement according to the invention, only subscriber counters are connected to different outputs of the coupler OK in FIGS. 5 and 6, only cost center counters to other outputs and subscriber counters and cost center counters to further outputs. Of course, the construction of a system will always be carried out uniformly. The uniformity of the structure of the arrangement shown in FIGS. 5 and 6 was only ignored in order to be able to show in a simple manner how versatile the usability of the coupler OK according to the invention for the transmission of counting pulses to subscriber counters, cost center counters, monitoring relays or the like is .
