Abstract

PURPOSE:To simplify the maintenance operation without performing the procedure of calling stop and release at a main distribution frame by providing a means extracting the subscriber service class of a calling subscriber based on internal information in a common controller. CONSTITUTION:When a call is connected at a common controller CM, the CM transmits connecting type information or the like received from an outgoing register OR via an outgoing register marker connector ORMC to an outgoing translator TLR and receives outgoing route information or the like as an output of the TLR. The CM selects an outgoing trunk OGT based on the TLR output and the connection between the calling subscriber SUB and the OGT is finished on a main link ML, and when this SUB is registered as calling stop on the subscriber data of a detector CPE detecting the service class, a special trunk SPT capable of handling talkie service of the outgoing stop subscriber is connected to the outgoing subscriber.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a method for controlling outgoing connections in a commonly controlled automatic telephone exchange.

[Prior art]

When a crossbar exchange, etc. temporarily suspends outgoing calls to any subscriber due to delinquent call charges, etc., the subscriber's line is disconnected at the entrance of the main wiring rack, and the exchange By disconnecting subscriber terminals, calls were made impossible. In this conventional method, a maintenance person is dispatched to the installation location of the main distribution rack to disconnect and reconnect the subscriber's line whenever necessary, and manually search for the relevant subscriber from the distribution panel housed in the multiplex. There was a need. In addition, since there is no sound to the subscriber, it may be misunderstood that there is a problem on the exchange side, which has a) disadvantage.

[Purpose of the invention]

The purpose of the present invention is to eliminate the above-mentioned drawbacks of the prior art, make maintenance work easier, notify the relevant subscriber that the call has been stopped, and provide information to parents regarding unmanned stations, etc. The purpose of the present invention is to provide a means that allows the maintenance authority, which is a station, to stop and cancel transmissions by remote control without dispatching maintenance personnel.

[Summary of the invention]

In the present invention, based on the internal information of the common control device.

Then, extract the subscriber service class of the calling subscriber.

By providing a detection device that detects the call joining.

If the subscriber is a call-stopping subscriber, the detection device sends the call-stop class information to the common control device, and the selected number, etc. that is part of the connection control information in the common control device is sent. By replacing this with second information and making a so-called special number connection, it is possible to connect to a special trunk that sends outgoing call stop calls.

[Embodiments of the invention]

FIG. 1 is a relay system diagram according to an embodiment of the present invention, and ML
is the main link, SUB is the calling subscriber, OR is the calling register, OGT is the outgoing trunk, SPT is the special trunk that can send outgoing (i-stop talkies), and CM is the common control device for the crossbar exchange.

The marker, TLR, also indicates a translator, which is an originating translation device. Further, CPE is a detection device that extracts the service class of a calling subscriber based on connection control information regarding the calling subscriber received from the CM, and TYP is an input/output device.

FIG. 2 shows the main circuit parts of a marker showing one embodiment of the present invention. An embodiment of the present invention will be described below with reference to FIG.

In FIG. 2, O8T is a relay for receiving on the marker CM side the outgoing subscriber identification result from the detection device CPE side;
ost is the contact point. In addition, d and et are detection relays DET that operate when the CPE performs call stop subscriber identification.
(not shown), and by closing dat, the relay O8T operates on the CM side, allowing the CM to know that the calling subscriber is the subscriber to whom outgoing calls are to be suspended.

In addition, TOG LE OG, A door, and Jo~7 are connected to the transmitter register marker 0flA4 from the transmitter register.
A relay that stores connection type information received by the CM via the C and selected number information made up of the I code.

0 to 7 are the contacts of these relays. Furthermore, RLK is the relay for confirming the recovery of the connection type information received by the CM from the transmission register, and CHF.
is the frame change instruction relay, and rlk and chf are the contacts of these σ month 1 Hayashi electric devices. Moreover, Odγ~9dr is the selection number received from the transmission register.

Relay for displaying the number of digits of characters o1) Contacts ck from IL to 9Drt
g It also shows the earth air supply connector CK (3 contacts) in the CM.

In Figure 2, when performing an outgoing connection operation with any CM,
The CM sends the connection type information 2 selection number information etc. received from the OR via the OI grip C to the TLR, and receives the outgoing route information etc. as the output of the TLR.

The CM selects OGT based on this TLR output.

Capture the connection between the calling subscriber SUB and the α)T on the ML.
However, if the i5IJB is registered as a call stoppage in the CPE's subscriber data, the CM, etc. performs the operations described below. In other words, the configuration is such that the CPE can monitor the calling subscriber accommodating location information among the connection control information in the CM when the subscriber (M) is raised from the OR, and the information is typed as subscriber data in the CPE. Referring to the subscriber class information table entered by a writer, etc., and identifying that the calling subscriber accommodating location information is in the calling stop class, the contact det of the detection relay 1) I penalty in the CPIc is activated. The transmission stop information receiving relay O8T on the CM side is operated and held in the earth-det-υST-battery path. When O8T operates, its contact 71 ort
As a result, the connection type information TOG or ORI, OG, and selected numerical information AO~7 to JO~7 are restored, and the known frame change instruction relay CHF is kept in operation, and although not shown in the figure, from I'lR to CN+ All connection control information based on the selected digits dialed by the caller, including outgoing route information received by the caller, is restored. The connection type information and selection number information are as above.

1. Since the T-OG operates through the OG-battery route, the selected digits dialed by the calling subscriber are the area code.

Even if the call contains a call, the TLR is restarted as a local outgoing call with the special number 1XY, which is necessary for the CM reconnection operation.

After receiving the outgoing route information etc. from the TLR, the call service is used to confirm that the subscriber is a subscriber who has suspended outgoing calls.

A connection is made between the special trunk SPT that can be used with the calling subscriber.

As described above, in this example, an embodiment related to an outgoing connection has been described, but the same operation applies to an in-house connection. Furthermore, although the present invention has only described the outgoing call stop function, the function of connecting to a special trunk, etc. based on the detection of the calling subscriber's service class can also be used to control connection to any talkie service, etc. other than outgoing call stop. There is no need to worry.

Next, the introduction and change of calling subscriber classes in the present invention will be explained. In the present invention, when it becomes necessary to take measures to stop outgoing calls, subscriber data stored in the horizontal axis storage section in the CPE can be manipulated via an input/output device such as a typewriter or magnetic tape device, so that unmanned stations can etc., it is possible to change the subscriber data of an unmanned station by remote control using a typewriter or magnetic tape device installed in the master station or the manned station in charge of maintenance, via a data transfer line using a modem, etc. This not only saves labor in maintenance, but also enables quick response to various measures.

FIG. 3 shows a specific circuit configuration within the CM of the portion related to the exchange of calling-stop subscriber identification information between the CPE and the CM in the present invention. In other words, since there are actually two calling subscribers, ・If the call is not from a German subscriber, a well-known joint identification circuit will identify the two joint subscribers. A determination is made as to whether it is A or B, but the time when all the connection control information in the CM is available is delayed due to this identification operation compared to the case of independent transmission. Therefore, in the case of a joint origination call, the CM transmits information such as the accommodation location of the calling subscriber.
A problem arises in that the timing of transfer from the call to the CPE is delayed compared to a call originating from a general subscriber. Figure 6 shows a solution to this problem, which is intended to make the call stop identification timing for individual calls and joint calls the same in terms of CM operation. G third to explain this using
In the figure, 10 STA and 08 TI3 transmit only the calling subscriber capacity 1 information from the CM to the CPE at the beginning of the CM operation sequence.

Next, as shown in Fig. 4, this is advance notice information regarding call restriction that is sent back from the CPE to the CM, and the conditions for driving either 08TA or 08TH of the CM in accordance with the type of subscriber subject to the restriction. is indicated by a circle. That is, CM
Based on the calling subscriber accommodating location information transferred from the CM to the apr; at the beginning of the operation sequence, the forged CPE uses the CM's 08TA in the case of a single subscriber's call stop and in the case of a joint call stop. Play one song per bottle. On the other hand, in the case of Kyodo B's call stop F, the CPE drives CMαm3. According to the above conditions, if the calling subscriber is alone,

In the case where the relay BP operates, the O8T maintains its operation, and in the case where the relay BP operates, the transmission stop operation described in FIG. 2 is performed. In other words, for a jointly originated call, as soon as the common Nl+ identification is completed within CA4, it is possible to determine whether or not the call is a stopped call. This is extremely advantageous compared to a method in which the detection device CPE K information is transferred at the same time and then the outgoing transmission stop operation is started.

〔Effect of the invention〕

As described above, the present invention makes it possible to perform simple maintenance work on stopping and canceling calls without having to perform them on the main distribution rack, and also makes it possible to notify the subscriber that the calls have been stopped, and to notify the station in charge of maintenance. It would also be possible to remotely control unmanned stations.
