Abstract

PURPOSE:To attain easily the operation indication of a destination incoming telephone set and automation of manual confirmation of talking through in- channel (through a channel) from an outgoing telephone set by adopting the circuit constitution that a call responds automatically to a pseudo terminal device at the incoming side and providing a means returning the own subscriber number and a reply code in receiving a control data from a outgoing side by the side circuit. CONSTITUTION:When outgoing/incoming telephone terminal sets 2, 3 make talking, a signal attended with the connection, that is, a subscriber line signal inputted/outputted to/from an exchange 1 via subscriber lines 4, 5, and a reply signal returned to the terminal sets 2, 3 from the exchange 1 thereby are transmitted/received by an outgoing telephone set control section 7 and an automatic incoming reply control section. Then the subscriber number of a talking destination 3 from the controller 9 and a control code commanding the confirmation are confirmed via a channel itself by means of a PB signal by transmitting the control code indicating the confirmation to an automatic reply control section 8 being a pseudo test equipment of a talking destination incoming telephone terminal device 3 for confirmation.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an exchange operation test device in an exchange system accommodating telephone terminals, and more particularly, to a call confirmation test suitable for identifying and controlling a telephone at the other end of a call. It is related to the device.

[Background of the invention]

For switchboard operation tests, i.e. tests that involve operating telephones, a conventional pseudo-call testing machine (this is simply an automatic machine that simultaneously performs a large number of operations from call origination to disconnection) or a series of operations can be performed manually. Test methods are being adopted.

The tests that are performed manually are used to confirm that all procedures for normal and abnormal conditions are executed correctly, but it is difficult to automate all of these complicated procedures.Furthermore, the person conducting the test changes every time, Even if the same person attempts to conduct the same test several days later, it would be foolish to conduct the test under the same conditions as the previous test.

In addition, newly developed programs require maintenance such as adding functions for many years afterward, but each time, it is necessary to confirm that the existing parts will operate correctly without being adversely affected by the addition of functions. The previous test was re-executed.

However, if this is done manually, there is a drawback that it is difficult to shorten the execution time as described above.

On the other hand, the pseudo call test equipment only generates a plurality of the simplest calls and uses them as a background load, and has the disadvantage that there is no variation in call types.

Furthermore, as shown in ``Japanese Unexamined Patent Publication No. 57-21153,'' a method for testing calls in digital exchanges is also known. This call testing method achieves its purpose by controlling the calling and receiving subscriber terminals, and also confirms calls by transmitting and receiving calls in both directions on a specific frequency. For this reason, in the former case, the test procedure becomes complicated because it is necessary to synchronize the calling/receiving subscribers on the test equipment side and carry out the test procedure. In addition, in the latter case, even if the call path is connected, testing procedures such as determining whether the called party is correct, determining whether the called party is correct, and placing a call on the called party after the call is connected, must be performed on the out-channel. However, there were problems such as lack of flexibility and complicated control programs.

[Purpose of the invention]

It is an object of the present invention to eliminate the problems in the prior art described above, to facilitate the call confirmation test procedure of a test device, and to automate the call confirmation test by hand and to provide operation instructions for the incoming telephone of the other party to the calling party's telephone. From inch yannel (
An object of the present invention is to provide a call confirmation test device that can be easily realized through a call path (through a call path).

[Summary of the invention]

A feature of the present invention is that in a call confirmation testing device for a telephone exchange, a circuit is configured such that a pseudo terminal on the called side can automatically respond, and the circuit receives control data from the calling side, that is, the number of the called party for call confirmation. By providing a means to return the subscriber's own subscriber number and response code when receiving the operation instruction code of the called telephone, it is possible to confirm the call, and the target to be controlled by the test control device is the operation of the calling telephone. , the test algorithm has been simplified.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a block diagram showing a specific circuit configuration, and the second
The figure is a flowchart.

In FIG. 1, 1 is a telephone exchange, 2 is a calling telephone terminal, 3 is a receiving telephone terminal, 4 and 5 are subscriber lines that connect the exchange and the telephone terminal, and 6 is an automatic verification device that tests the functions of the exchange 1. 7 is a calling telephone testing section that is connected to the subscriber line 4 corresponding to the calling telephone 2 and simulates the calling telephone 2, and 8 is a subscriber line 5 corresponding to the receiving telephone 3.
9 is connected to an automatic answering control unit which simulates the incoming telephone set 3; and 9 is connected to the outgoing telephone testing unit 7, which controls the function confirmation test means of the telephone exchange and the resulting control to confirm the normality of the operation. It consists of devices.

First, an overview of this embodiment will be explained with reference to FIG.

Generally, when testing the functionality of an exchange manually, the normality of the exchange is confirmed by making a call from the originating telephone terminal 2 and being able to make a call connection to the receiving telephone terminal 3. In this automatic verification test device, the call is mechanically verified between the originating telephone controller 7, which simulates the originating telephone terminal 2, and the incoming call automatic answering controller 8, which simulates the incoming telephone terminal 3, under the control of the control device 9. This is done by In other words.

When the calling and receiving telephone terminals 2 and 3 make a call, the signals associated with the connection, that is, the subscriber line signals that are input and output to the exchange 1 via the subscriber lines 4 and 5, and the signals that are transmitted from the exchange 1 due to the subscriber line signals are transmitted. A response signal to be sent back to the called subscriber terminal 2.3 is transmitted and received by the calling telephone set control unit 7 and the automatic call answering control unit, in particular.

The originating telephone control section converts the physical signal into a logical code, communicates with the control device 9, and performs a call connection test by controlling the test procedure 9. and the calling/receiving subscriber terminal 2,
3 is in the busy state, as a means of checking whether the called party's telephone is the correct telephone, the control device 9 sends the subscriber number of the called party 3 and a control code instructing its confirmation to the inch channel. , that is, via one communication path itself, from the PB double signal to the destination telephone terminal 3 of the other party.
It is sent to the automatic response control unit 8, which is a pseudo test device.

On the other hand, when the automatic response control unit 8 receives it, it recognizes that it is a call confirmation request and sends a response code to the originating telephone control unit 7 indicating that it is possible to talk to its own subscriber number (called DN). Reply from PB double signal. Then, this PB double signal received by the calling telephone test section 7 is notified to the control device 9, and the control device 9 confirms that the call between the subscribers 2 and 3 is normal according to the testing means it has in advance. confirm. It is also possible to issue a command from the control device 9 to this control code for the next operation from the call state, for example, to make a first call to the called party, that is, to end the call by pressing the called party.

Next, the algorithm of the call confirmation means will be explained with reference to the flowchart shown in FIG. Originating means (a)) 12, *J
f14□9,. , Tse7゜□□ means, and the destination means (
b) shows the operating means of the destination automatic response control section 8. First, the originating telephone controller 7 inputs a calling signal to the exchange and receives a dial tone (DT) from the exchange. Thereafter, the dial information of the first subscriber 3 to be called is sent. When reception is completed on the exchange 1 side, the exchange enters a calling state, and the originating side receives a ringback tone and the destination side receives a ringing signal. After that, the receiving side automatic response control unit 7
A response signal is sent back to the exchange. As a result, the exchange transitions to a call connection state, and the ring bank tone stops on the originating side. Using this as a trigger,
It recognizes that the state has transitioned to a call state and instructs the called party's subscriber number and response confirmation, and in some cases, after confirming the call, the callee on the called party instructs the caller to take an action after a certain period of time. The code is transferred to the automatic response control unit on the destination side using the PB double signal, and a response waiting state is entered. The automatic response control unit 8 on the receiving side confirms that the received subscriber number matches the own subscriber number, returns the own subscriber number and a response code indicating that the call confirmation signal has been received, and controls the If there is a code, the called party performs operation timing processing. The calling party uses the call confirmation information received from the called party and a response code indicating that the called party is in the process of making a call.

When the timing is out on the 0-terminating side which confirms that the other party is normal and enters the waiting state again, the automatic response control unit 8 terminates the call on the 1-terminating telephone 3 (calls the called party first).
Perform a simulation of Then, on the exchange side, the called party takes the timing and sends a disconnection signal to the calling side after monitoring the re-response of the called side, and then sends a disconnection signal to the calling side. A busy tone is returned.

As described above, it becomes possible to control the call confirmation and the operation of the called party's telephone in a single channel. As described above, according to this embodiment, a test device that simulates a telephone calling function is connected in multiple ways to a subscriber line between a telephone exchange and a subscriber telephone terminal, and other subscriber lines can be automatically answered as an incoming telephone. In a call confirmation test device that performs a functional confirmation test of a telephone exchange by focusing on the operation of the calling side telephone, it is equipped with circuit functions such as means for transmitting and receiving information such as an identification code, a control code instructing the next operation of the destination automatic terminal, and a response code related to the operation instruction through the five communication paths;
Since a means for determining the other party of the call and a means for interpreting and executing the control code are provided to confirm the call, the call confirmation and the operation of the called party's telephone can be controlled (transmission and reception) in a single channel.

〔Effect of the invention〕

As is clear from the above-described embodiments, according to the present invention, the telephone connection control procedure algorithm of the common control device can be simplified and facilitated by using the automatic response means of the telephone test terminal on the called side. In addition, it is possible to confirm the communication between the calling side telephone test terminal and the called side telephone test terminal through a communication path, and furthermore, it is possible to use a means to instruct the operation of the called side telephone test terminal from the calling side telephone test terminal. ,
This method has the advantage that it is possible to perform a call confirmation test with expandability and flexibility in test conditions.
