〔Example〕

The figure is a block diagram showing one embodiment of the present invention.

In the figure, 1 is the calling phone, 2 is the switch frame, and 3
4 is a destination telephone, 4 is a marker, 5 is a number group (hereinafter abbreviated as NG), and 6 is a talkie, which shows the general configuration of a crossbar exchange.

This embodiment includes a modem 7 for receiving a suspended telephone number from a terminal for registering suspension of usage in a remote location via a general telephone line, an NG relay drive circuit 14 for driving NG, an NG relay drive and grinding circuit 15, NG scanning circuit 12 that reads NG output information, NG scanning control circuit 13, marker scanning circuit 8 that scans the relay operation of marker 4, marker scanning control circuit 9, marker relay drive circuit 1D that drives the relay of marker 4, A remote usage suspension device 18 consisting of a marker relay drive control circuit 11, a control circuit 16 that controls the operation of each part, and a memory circuit 17 that stores data can suspend and cancel usage of a subscriber accommodated in a crossbar exchange at a remote location. This is how it was done.

The operation of this embodiment will be explained with reference to the drawings. This embodiment has the following operational functions: (1) registration/cancellation of usage suspension, (2) usage suspension (when making a call), and (6) usage suspension (when receiving a call), which will be explained in order.

[Use suspension registration/cancellation]

Registration of a suspended subscriber is performed by dialing the subscription telephone number of the remote usage suspension device 18 from a registration terminal (not shown), and the registration terminal and modem 7 are connected via a general telephone line by known means. , the modem 7 activates the control circuit 16. The control circuit 16 activates the memory circuit 17, receives the telephone number of the suspended subscriber sent from the registration terminal through the modem 7, and stores it in the memory circuit 17.

The control circuit 16 activates the NG relay drive circuit 14 and the NG relay drive control circuit 15, drives the telephone number relay of NG5, and cuts off the power supply to the NG representative subscriber busy test circuit. NG5 converts the telephone number into the accommodation location using a known means and outputs it. In the case of a representative subscriber as well, since the representative subscriber busy test circuit is powered off, the representative pilot number is assumed to be empty and is converted to the accommodation position and output. Control circuit 1
6 activates the NG scanning circuit 12 and NG scanning control circuit 13, reads the accommodation position output of NG 5, and stores it in the memory circuit 17. The accommodation position output of NG5 can be detected by a method of detecting voltage.

As described above, the telephone number and accommodation location of the suspended subscriber are registered. Similarly, for cancellation of usage suspension, the registration terminal and modem 7 are connected, the control circuit 16 receives the telephone number sent from the registration terminal at the modem 7, and uses the registered data in the memory circuit 17 to determine the telephone number and the accommodation location. This is done by erasing.

[Suspension of use (when making a call)]

In the figure, it is assumed that the calling telephone 1 is a suspended subscriber, and that usage suspension registration has already been performed in the memory circuit 17 by the method described in the above-mentioned section [Usage suspension registration/cancellation].

When the originating telephone 1 goes off-hook and dials the telephone number of the destination telephone 6 to which it is trying to make a call, the train of the switch frame 2 is closed by the marker 4 using a known method. The control circuit 16 activates the marker scanning circuit 8 and the marker scanning control circuit 9 to read the operation of the side subscriber accommodation position relay. Succession? It is also possible to read the operation of the relay by detecting the relay drive voltage or by forming a loop circuit using the operating contacts of the relay and detecting the loop current.

The control circuit 16 compares the originating subscriber accommodating position information obtained from the scanning result with the discontinued subscriber information registered in the memory circuit 17. If they match, the control circuit 16 controls the marker relay drive circuit 10 and the marker relay drive side production circuit 11. It starts and drives the disabling relay of marker 4.

The marker 4 stops the connection operation to the destination telephone 3 by the operation of the suspension relay, performs the connection operation to the suspension talkie 6, closes the train of the switch frame 2, and then closes the train of the switch frame 2. Outgoing calls are regulated by connecting the telephone 1 and the disabled talkie 6.

When a general subscriber who is not a suspended subscriber makes a call, there is no match as a result of the comparison, so the control circuit 16 does not drive the suspended relay of marker 4, marker 4 performs the normal connection operation, and the calling telephone 1 and the destination telephone 3 is connected.

[Suspension of use (when receiving a call)]

In the figure, it is assumed that the called telephone 3 is a suspended subscriber, and that usage suspension registration has already been performed in the memory circuit 17 by the method described above in the section [Usage suspension registration/cancellation].

When the originating telephone 1 goes off-hook and dials the telephone number of the destination telephone 30, the marker 4 closes the train of the switch frame 2 using a known method, as explained in the section [Suspension of use (when making a call)]. The control circuit 16 activates the marker scanning circuit 8 and the marker scanning control circuit 9 to read the operation of the collapsed subscriber accommodation position relay during the marker 4 connection operation.

Relay operation can be read using the method described in the section [Suspension of use (when making a call)].

The control circuit 16 compares the accommodating location information of the destination subscriber based on the scanning result with the suspended subscriber information registered in the memory circuit 17, and if they match, activates the marker relay drive circuit 10 and the marker relay drive sterilization circuit 11. Then, the relay for stopping the use of marker 4 is activated. Marker 4 stops the connection operation to the destination telephone 3, which is the suspended subscriber, by the operation of the suspended relay, performs the connection operation to the suspended talkie 6, closes the train of switch frame 2, and joins the general subscriber. By connecting the calling telephone 1, which is the subscriber, and the suspended talkie 6, incoming calls to the receiving telephone 3, which is the suspended subscriber, is restricted.

Furthermore, when a call is received to a general subscriber who is not a suspended subscriber, the control circuit 16 does not drive the suspended relay of marker 4 because there is no match as a result of the comparison, marker 4 performs the normal connection operation, and the calling telephone 1 and the destination telephone 6 is connected.

As described above, it is possible to suspend the use of a subscriber accommodated in a crossbar exchange from a registration terminal installed at a remote location. As is clear from this result,
Compared to conventional technology, it is possible to suspend or cancel the use of voluntary subscribers at any time, which is expected to significantly improve work efficiency.

In the figure, both the calling side telephone 12 and the receiving side telephone 6 are housed in the same crossbar exchange, but it is not necessary that both the calling side and the terminating side are housed in the same exchange. In the case of suspension of use on the calling side, even if the telephone on the called side is accommodated in another exchange, the suspension processing will not be affected.Similarly, in the case of suspension of use on the called side, even if the telephone on the called side is accommodated in another exchange, the suspension processing will not be affected. It does not affect. Although the explanation has been given for the case where the same exchange is accommodated on both the originating and terminating sides as shown in the figure, this is only for convenience.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to suspend the use of any subscriber accommodated in a crossbar exchange by controlling it from a registration terminal installed in a remote location, and It can be stopped and canceled at any time, contributing to a significant improvement in work efficiency.
