[Industrial application field]

The present invention relates to an automatic response meeting tester for communication networks connected to existing exchanges via subscriber circuits.

With the recent digitalization of communication systems, private exchanges (P
BX), the peripheral exchange and its communication path have been converted to 4 wires, and a meeting test is conducted to confirm the functionality of the communication network (conduct a call with the person at the other station and confirm that normal calls can be made). When performing this on a test device, it is necessary to check not only the communication from the other subscriber (confirming the reception path), but also the communication of the signal tone from here to the other subscriber (confirming the transmission path). It has started to be done.

In addition, with the recent diversification and expansion of telephone exchange networks, call confirmation (debut test) including multiple relay stations has become increasingly difficult.
There is a strong demand for automatic processing with less manpower.

[Prior Art and Problems to be Solved by the Invention] FIG. 2 is a diagram explaining a conventional match test method, in which (a) shows an example of a communication network, and (b).

(c) shows an example of the configuration of a conventional encounter test mechanism.

Traditionally, for example, when a communication network as shown in Figure (a) is constructed, one of the three tests to confirm the connection function of the communication network is a meeting test (conversation with a person at the other station, and verification of normal operation). (confirm that you can make a phone call), and
The normality of the communication network was 6'&i=.

In this Deai test, testers are on standby at each location of the above communication network to confirm calls, so if the network is expanded at even one location, the Deai test including other locations will be delayed. It is necessary to send a tester to test subscribers of each exchange in the communication network, and there is a problem that it is no longer a realistic testing method as communication networks become more diverse and expanded, as has been the case in recent years. Ta.

For example, in the communication network shown in (a),
In the call connection test from the exchange (^) to the exchange (D),
A −+ C-OD root and A) B-=>C→D
It was necessary to confirm the connection with the route of , and it was necessary to send a tester to station B in addition to station 0.

Another test method is to use the automatic response test mechanism shown in Figures (b) and (c).

The figure (b) shows an example in which an automatic answering trunk (AT) is connected to an exchange, for example, a private exchange (PBX).

This automatic answering trunk (AT) is provided as part of the switching system function, and when the trunk (AT) is empty, it is connected and automatically confirms the connection to the calling subscriber. It sends out signals.

This mechanism is a system function, so it was added later.

There is a problem that it cannot be expanded.

Figure (c) shows an example in which an automatic response device is connected to the private exchange (PBX).

When the incoming call detection unit 1 detects an incoming call to the automatic response device, the automatic response control unit (loop detection unit) 5 is activated and the connection T
If the if1 recognition signal transmission signal transmission section sends out a signal tone, and the loop detection section 5 detects that the caller is on-hook,
It operates to stop sending out the connection confirmation signal.

In either method (b) or (c) above, even if it is possible to confirm the signal tone from the other subscriber to the automatic answering device, etc., the contact sent from the automatic answering test mechanism cannot be confirmed.
There is a problem in that it is not possible to confirm whether or not the tttrJ'fl acknowledgment signal has reached the other subscriber, and as mentioned above, in the case of a four-wire switching system, the reception path is Even if confirmation was possible, there was a problem in that the connection of the transmission path could not be confirmed.

In view of the above-mentioned conventional drawbacks, the present invention is an automatic response tester for a communication network that is connected to an existing exchange through a subscriber circuit. It is an object of the present invention to provide an automatic response tester capable of conducting a test of a communication network without dispatching a tester to each exchange.

[Means for Solving the Problems] The above problems are solved by an automatic response encounter tester for a communication network configured as follows.

This is an automatic response detection tester for a communication network connected to an existing switchboard via a subscriber circuit (LC), which responds to an incoming call from the switchboard and detects the multi-frequency signal' that is subsequently sent. A first means of accumulating a specific subscriber number from a call requester by receiving the call, and disconnecting the incoming call at the time when the specific subscriber number with a predetermined number of digits is received. a second means, after automatically disconnecting the incoming call, dialing the specific subscriber number from the received call request source to control the call, and connecting to the specific subscriber to confirm the call; It consists of a third means for performing.

[Effect]

That is, according to the present invention, when an automatic response meeting tester of a communication network connected to an existing exchange via a subscriber circuit receives a call from a specific originating subscriber from a private exchange (PBX), for example, respond in the automatic response control section,
The multi-frequency signal (PB double signal) sent after that is
Send to signal receiving section.

The PB signal receiving section converts the multi-frequency signal into numbers and sends them to the number storage section for storage.

When the number storage unit receives the required number of digits, it automatically disconnects the incoming call and then activates the network control unit.

The network control unit transmits the dial signal to the private exchange (PBX) according to the dial number stored in the number storage unit.
) to perform transmission control.

Through the above operations, for example, a connection is established with the originator of the call request, and a connection confirmation signal similar to the conventional system is sent to confirm the call.

By installing such an automatic response meeting test machine in each exchange, after the tester dials the automatic response meeting test machine from a specific originating subscriber, for example, a dial signal of his own subscriber number is sent. By sending out (multi-frequency signal) and receiving a connection confirmation signal from the automatic response detection tester,
Connection confirmation tests between the transmitting path and the receiving path can be performed only from the own station.

Furthermore, by blocking the communication path between the local station and the other station, it is possible to confirm the connection of a detour route to the other station.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a diagram showing an embodiment of the present invention, in which after receiving an incoming call to the automatic response meeting tester, a multi-frequency signal (PB double signal) sent from the calling subscriber is received. For example, the present invention is implemented by a means for storing the dial number of the originating subscriber, disconnecting the incoming call, and then controlling the originating subscriber to make a call and confirming the connection based on the response from the other party. The same reference numerals indicate the same objects throughout the figures.

Hereinafter, the configuration and operation of the automatic response meeting tester for a communication network according to the present invention will be explained with reference to FIG.

The automatic response meeting tester of the present invention can be installed, for example, in an existing private exchange (PBX) at each node of the communication network.
is connected to the subscriber circuit via the subscriber circuit.

In this test device, in response to an incoming call from the other station or within the own station, ■ an incoming call detection signal detected by the incoming call detection unit l is sent to the automatic response control unit 5, and the connection is confirmed from the automatic response control unit 5. The signal sending unit 6 is started and a connection confirmation signal is sent for a certain period of time to perform an automatic response.

■When the originator receives the connection confirmation signal, it sends out a multi-frequency signal (PB double signal) indicating the dial number for re-repeat. This dial number for re-repeat may be its own subscriber number or For example, it may be another subscriber number to which a level tester or the like is connected.

(2) The above-mentioned multi-frequency signal is received by the PB signal receiving section 2, converted into dialed numbers, and sent to the number storage section 3, where the dialed number for reissue is stored. When a dial number with the required number of digits is received, it notifies the automatic response control section 5, performs automatic disconnection (loop opening), and activates the network control section 4.

(2) The network control unit 4 converts the dial number stored in the number storage unit 4 into, for example, a multi-frequency dial signal, and controls a private exchange (PBX) to make a call.

■The automatic response control unit (loop detection unit) 5 detects the response of the other subscriber (in this example, the own extension number different from the calling subscriber) via the incoming call detection unit 1, and the connection is established. The confirmation signal sending unit 6 sends out a connection confirmation signal, and the other subscriber confirms the connection confirmation signal.

The above operation will be explained using a specific example.

For example, dial from 800-2999 and dial as follows.

801 (destination station number where the test device is located) - 3999 (number of the subscriber circuit of the test device) ...800 (own station number) - 2998 (own extension number) With this operation, the caller can After confirming the response of the response tester (based on the connection confirmation signal), it sends out the number of the subscriber to whom the level measuring device is connected within the same local station as the source subscriber, using a multi-frequency signal. , wait for automatic disconnection. Thereafter, a call is received from the automatic answering tester to the subscriber at number 800-2998 within the own station, and when the subscriber's telephone rings and answers, a connection confirmation signal is sent.

In this way, a multi-frequency signal (
The transmission route can be confirmed by sending the re-transmission number).

Furthermore, by confirming the receiving path using the connection 6' (l confirmation signal) from the tester and measuring the level of the connection confirmation signal, it is also possible to measure the amount of attenuation of the connection path.

Furthermore, by blocking the connection path from the partner station to which the test device is connected and performing the above-described transmission operation, connection of the detour route can be confirmed.

As described above, the present invention allows an automatic response meeting tester for a communication network connected via an existing exchange and a subscriber circuit to detect an incoming call and then cause the caller to send out a re-call number using a multi-frequency signal. The multi-frequency signal is converted into a dial number and stored, and after the incoming call is automatically disconnected, the call is made using the stored re-call number (by performing 3 controls, the call is made using the multi-frequency signal). The feature is that it is possible to confirm the transmission path from the receiving side to the receiving side, and to confirm the receiving path by sending a normal connection confirmation signal to the calling party.

(Effects of the Invention) As explained above in detail, in the automatic response encounter test of the communication network of the present invention, in response to an incoming call from the exchange, a multi-frequency signal sent thereafter is received. a first means for accumulating a specific subscriber number from a calling request source; and a second means for disconnecting the incoming call when a predetermined number of digits of the specific subscriber number is received. and after automatically disconnecting the incoming call, dialing a specific subscriber number from the received call request source to control the call, connect to the other subscriber and make a call (ii) By installing such an automatic response meeting test machine in each exchange, after the tester dials the automatic response meeting test machine from a specific calling subscriber, For example, by transmitting a dial signal (multi-frequency signal) of your own subscriber number and receiving a connection confirmation signal from the automatic response meeting test membrane, you can perform a connection confirmation test between the transmission path and the reception path from your own station. It can be done only by

Furthermore, by blocking the communication path between the local station and the other station, it is possible to confirm the connection of a detour route to the other station.
