〔Example〕

FIG. 1 is a block diagram showing an embodiment of the present invention. In the figure, 1 is a calling side telephone, 2 is a switch frame, 3 is a receiving side telephone, 4 is a marker, 5 is a number group (hereinafter,
(Abbreviated as NG) and 6 are tokes, which show the general configuration of a crossbar exchange.

In the present embodiment, a modem 7 for receiving a suspension telephone number from a remote suspension registration terminal via a general telephone line, an NG relay drive circuit 14 for driving NG, an NG relay drive control circuit 15, NG. NG scanning circuit 12 that reads the output information of NG
Scan control circuit 13, marker scanning circuit 8 for scanning relay operation of marker 4, marker scanning control circuit 9, marker relay drive circuit 10 for driving relay of marker 4, marker relay drive control circuit 11, control operation of each part Control circuit 16,
A remote use suspending device 18 composed of a memory circuit 17 for storing data allows the use of a subscriber accommodating a crossbar exchange to be suspended and released at a remote place.

The operation of this embodiment will be described with reference to the drawings. In this embodiment, there are (1) usage suspension registration / cancellation, (2) usage suspension (when making a call), and (3) usage suspension (when receiving a call), so they will be described in order.

[Use suspension registration / cancellation]

The registration of the suspended subscriber is performed by dialing the subscription telephone number of the remote suspension device 18 from a registration terminal (not shown) so that the registration terminal and the modem 7 are connected via a general telephone line by a known means. The modem 7 activates the control circuit 16. The control circuit 16 activates the memory circuit 17 and sets the telephone number of the suspended subscriber sent from the registration terminal to the modem 7
Received by and stored in the memory circuit 17.

The control circuit 16 activates the NG relay drive circuit 14 and the NG relay drive control circuit 15 to drive the NG5 telephone number relay and cut off the power supply to the NG representative subscriber busy test circuit. NG5 is converted from a telephone number to a storage position by a known means and then output. In the case of the representative subscriber as well, since the power of the busy circuit of the representative subscriber is cut off, the representative pilot number is regarded as empty and converted to the accommodating position and output. The control circuit 16 is an NG scanning circuit
12. The NG scan control circuit 13 is activated to read the accommodation position output of NG5 and store it in the memory circuit 17. The output of the accommodation position of NG5 can be detected by the voltage detection method.

As described above, the telephone number and accommodation position of the suspended subscriber are registered. In the same manner as for the release of the use suspension, the registration terminal and the modem 7 are connected, and the control circuit 16 receives the telephone number sent from the registration terminal by the modem 7, and from the registration data of the memory circuit 17 together with the accommodation position. It is done by erasing.

[Suspension (when making a call)]

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

When the originating telephone 1 goes off hook and dials the telephone number of the terminating telephone 3 that is about to make a call, the train closing of the switch frame 2 is performed by the marker 4 by a known means. The control circuit 16 reads the operation of the side subscriber accommodation position relay by activating the marker scanning circuit 8 and the marker scanning control circuit 9. The relay operation can be read by a method of detecting a relay drive voltage or a method of forming a loop circuit by using an operating contact of the relay to detect a loop current.

The control circuit 16 compares the calling-side subscriber accommodation position information, which is the scanning result, with the usage-stopped subscriber information registered in the memory circuit 17, and if they match, activates the marker relay drive circuit 10 and the marker relay drive control circuit 11. Then, the use stop relay of the marker 4 is driven. 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 torch 6, closes the train of the switch frame 2, and the calling party who is the suspension subscriber. Calling is restricted by connecting the telephone 1 and the suspended torch 6.

Further, when a general subscriber who is not a usage-disabled subscriber makes a call, the control circuit 16 does not drive the usage-disabled relay of the marker 4 because there is no match as a result of the comparison, and the marker 4 performs a normal connection operation and the calling side telephone 1 And the destination telephone 3 is connected.

[Suspension (when receiving a call)]

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

When the calling side telephone 1 is off-hook and the telephone number of the destination side telephone 3 is dialed, the marker 4 performs the train closing of the switch frame 2 by a known method as described in the section [stopping use (during call)]. The control circuit 16 activates the marker scanning circuit 8 and the marker scanning control circuit 9 to read the operation of the destination-side subscriber accommodation position relay during the connecting operation of the marker 4. The operation of the relay can be read by the method described in the section [Discontinuation of use (during transmission)].

The control circuit 16 compares the receiving side subscriber accommodation position information, which is the scan 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 control circuit 11. , The use stop of the marker 4 is driven. The marker 4 stops the connection operation to the destination telephone 3 which is the suspension subscriber due to the operation of the suspension relay, performs the connection operation to the suspension torch 6, and closes the train of the switch frame 2 to make a general subscription. By connecting the calling-side telephone 1 which is the caller and the use-stopped torch 6, incoming calls to the called-side telephone 3 which is the use-stopped subscriber are restricted.

In addition, when a general subscriber who is not a suspended subscriber receives a call,
Since there is no match as a result of the comparison, the control circuit 16 does not drive the relay for suspending use of the marker 4, and the marker 4 performs a normal connection operation to connect the calling telephone 1 and the called telephone 3.

As described above, the use of the subscriber accommodated in the crossbar exchange can be suspended from the registration terminal installed in the remote place. As is clear from this result, compared with the conventional technique, the use of the optional subscriber can be suspended / released at any time, so that a significant improvement in work efficiency can be expected.

In the figure, both the originating side telephone 1 and the destination side telephone 3 are accommodated in the same crossbar exchange, but both the originating side and the destination side need not be accommodated in the same exchange. If the calling side usage is suspended, even if the receiving side telephone is accommodated in another exchange, it does not affect the usage suspension process. Similarly, if the originating side usage is suspended, the calling side telephone is not handled even if the calling side telephone is accommodated in another exchange. It does not affect. Although the description has been given for the case where the same exchange is accommodated on both the originating side and the terminating side as shown in the figure, this is for convenience only.

〔The invention's effect〕

As described above, according to the present invention, the suspension of use of any subscriber accommodated in the crossbar exchange can be controlled by controlling the registration terminal installed at a remote location,
The suspension and cancellation of the use of optional subscribers can be performed at any time, which contributes to a significant improvement in work efficiency.
