The present invention relates to a telephone exchange testing device that can be connected to an electronic exchange, operate the electronic exchange in real time close to the actual usage condition, and dynamically test the connection status, operation, performance, etc.

[Prior Art] In conventional telephone exchange test equipment, a tester for testing telephone functions or a tester for trunk functions is connected to each corresponding terminal of the telephone exchange, and a predetermined standard test device is connected to the corresponding terminals of the telephone exchange. Transmitted signals are sent to a telephone exchange and the response signals are individually checked, and the connection status, operation, etc. of each is individually tested.

[Problems to be solved] This type of test method not only makes it impossible to check the overall performance because the operating conditions do not correspond to the actual usage conditions, but also makes it difficult to check the overall performance because a large number of terminals are handled individually. There is a problem that takes time. Therefore, it is impossible to test under conditions close to actual operation, and it is not possible to set even more severe conditions and examine the limit performance.

The first telephone simulator receives control information regarding the transmitting/receiving operation of the telephone, such as dialing information or transmission of transmission data, from the simulation control section, simulates the telephone, and performs specified operations. The trunk simulator exchanges information with the telephone exchange, receives response information from the telephone exchange, and sends it to the simulation control section.The trunk simulator exchanges information with the telephone exchange and receives response information from the telephone exchange regarding the trunk. Sends information to the simulation control section, performs connection according to the information, sends reception information sent from the telephone exchange to the second telephone simulator, and receives information regarding the telephone's transmitting/receiving operation obtained from the second telephone simulator. The second telephone simulator receives control information regarding the telephone's sending/receiving operations from the simulation control section, simulates the telephone, executes specified operations, and transmits the information to the trunk simulator. The trunk simulator exchanges information with the telephone exchange through the trunk simulator and sends information from the trunk simulator to the simulation control section. The control information regarding the transmitting/receiving operation of the telephone is sent to the second telephone simulator, and the first and second telephone simulators are sent to the second telephone simulator. The information obtained from the second telephone simulator section and the trunk simulator section is compared with the corresponding expected value information to determine whether or not they match.

Here, the extension telephone group simulator section 3 has input/output terminals connected to the electronic exchange 1 corresponding to the number of telephones actually connected (number of channels), and each of these terminals (or each channels) are respectively connected to each terminal (or each channel) of the telephone connection of the electronic exchange 1. Then, it receives various types of information related to the telephone transmitting/receiving operation such as dialing information or transmission data from the simulation control unit 7, and refers to the station data file 78 according to the information to determine the logical line address such as the telephone number and the physical line address. It simulates a specific telephone, executes the specified operation, exchanges information with electronic exchange 1, and receives response information from electronic exchange 2. The various response information received from the electronic exchange is
It is sent from the extension telephone group simulator section 3 to the simulation control section 7.

The switchboard simulator section 4 has input/output terminals connected to these lines in correspondence with the number of switched lines of the electronic exchange 1, and each of these terminals (or each channel) corresponds to the number of switched lines of the electronic exchange 1. It is connected to each terminal (or each channel) of the connection. Then, in response to the output signal of the electronic exchange l, dial information etc. set in advance is sent to the simulation control unit 7, response information corresponding thereto is obtained from the simulation control unit 7, and this is sent to the electronic exchange l. .

The trunk simulator section 5 connects input/output terminals connected to these lines in accordance with the actual number of lines connected to the electronic exchange 1, and each of these terminals (or each channel)
are connected to each terminal (or each channel) of the trunk line connection of the electronic exchange 1. The trunk simulator section 5 is internally connected to the other party's telephone group simulator section 6, and information is individually exchanged with each simulated telephone on a channel corresponding to the number of telephones to be realized. be done. The trunk simulator unit 5 then exchanges information with the electronic exchange 1, sends the information regarding the trunk received from the electronic exchange 1 to the simulation control unit 7, and refers to the station data file 78 according to the information to determine the logical line address. The connection is switched by matching the physical line address and the physical line address. - The other party's telephone set simulator unit 6 receives information regarding the transmitting/receiving operation of the telephone from the simulation dft control unit 7, and refers to the station data file 78 according to this information to determine the logical line address and physical line address. Correspondence of line addresses is taken, a specific telephone is simulated, the specified operation is executed, information is exchanged with the electronic exchange 1 via the trunk simulator section 5, and the trunk simulator section 5
The information obtained is sent to the simulation control section 7.

The simulation control unit 7 includes an extension telephone test sequence processing unit 71 and a switchboard test sequence processing unit 72.
, trunk test sequence processing section 73, other party's telephone test sequence processing section 74, large amount of parallel processing control section 76
It is equipped with Each test sequence processing unit is composed of a microprocessor and a memory storing a microprogram, and executes a predetermined process when a certain microprogram is activated.

Here, the extension telephone test sequence processing section 71 controls the internal telephone packing machine simulator section 3 according to the event information, and compares and determines the response information received therefrom with an expected value. Switchboard test sequence processing? Similarly, the PJ 72 controls the switchboard simulator section 4 according to the event information, and the trunk test sequence processing section 73 controls the trunk simulator section 5 according to the event information, compares and judges the response information received from the switchboard simulator section 5 with the expected value, and performs a telephone test on the other party. The sequence processing unit 74 controls the other party's telephone group simulator unit 6 according to the event information, and compares and determines the response information received from the simulator unit 6 with an expected value.

The extension telephone test sequence processing section 71 , the switchboard test sequence processing section 72 , the trunk test sequence processing section 73 , and the other party's telephone test sequence processing section 74 are controlled by the multiple parallel processing control section 76 .
Multiple control is performed under the control of , and each performs parallel processing. The event information is obtained by each test sequence processing section by referring to the event table group 76 and the status table 77, respectively. On the other hand, station data file table 78
is a table that converts a physical channel for the switching operation of the electronic exchange 1 into a logical channel such as a telephone number to be connected, and is transferred to the electronic exchange 1 and stored on a magnetic disk as an internal memory. It is stored in the device, etc., and is referenced by each simulator section to obtain a physical line address from a logical line address such as a telephone number, and is also referenced by each test sequence processing section as needed.

On the other hand, each test sequence processing section such as the extension telephone test sequence processing section 71 determines whether the information obtained from each simulator section such as the extension telephone group simulator section 3 matches the expected value or not based on the information specified in the event table group 76. The determination is made by referring to the information that is the expected value in the event table, or by receiving that information via the multi-parallel processing control unit 76.

As a result of this judgment, if it matches the expected value, the process moves on to the next test, and if it does not match, it is sent to the multi-parallel processing control unit 76 and the status is displayed on a CRT display (not shown) or the like. indicate. This allows the state of the electronic exchange 1 to be operated in real time close to the actual usage state, and to dynamically test the connection state, operation, performance, etc.

The multi-parallel processing control unit 76 controls the operation timing of each simulator unit, transfers the expected value obtained from each simulator unit to another simulator unit that performs comparison judgment, and receives the abnormality judgment result from each test sequence processing unit. Obtain information and perform abnormality processing such as displaying it on a CRT display.

Next, a specific example of the operation of the electronic exchange testing apparatus 2 will be described with reference to the event table in FIG. 2 and the status table in FIG. 3.

First, the station data file table 78 is transferred to the internal storage device of the electronic exchange 1. This station data file table 78 consists of a channel-to-extension number conversion table, a channel-to-trunk number conversion table, and other special data such as a night switching number, a representative telephone number, and a group number. etc. are added.

Here, in the channel-extension number conversion table, each channel (CHI (i=1-n)) provided corresponding to the physical terminal of the electronic exchange l is connected to which extension telephone number it corresponds. The channel-trunk number conversion table indicates whether each channel (CHl (i=1 to m)) provided corresponding to the input/output terminal of the electronic exchange 1 connected to an outside line is connected to the trunk simulator section. This shows which trunk number of 5 the trunk is connected to.

Now, when a certain test item [1 is specified from the keyboard (not shown), the multi-parallel processing control unit 76 sends the extension telephone test sequence processing unit 71 the starting address of the program that generates the event corresponding to the test item. The data is expanded to each test sequence processing unit including the first and sent to each test sequence processing unit.

The extension telephone test sequence processing unit 71 sequentially reads out the programs at the addresses and creates the event table group 7.
6, the state of the extension telephone test sequence processing unit 71 is sequentially set from the table, and each telephone is simulated to a predetermined state.

For example, if address 1 of the A/event table shown in FIG. 2 of the event table group 76 is specified for a certain extension telephone 2143, the first column indicating the type of event is "outgoing". , among them, sends control information for placing the IIa telephone in a calling state to the extension telephone group simulator section 3. The extension telephone group simulator section 3 simulates a designated extension telephone 2143 into a calling state and waits for the next information. This calling status signal is sent via the input/output terminal of the extension telephone 2143 to the terminal of the electronic exchange 1 connected thereto, and the electronic exchange 1 receives information indicating the extension and dialing information of the other party from the extension telephone 2143. The receiver enters the state of attaching. In addition, A/
As the event information for address l in the event table, there is no switchboard address because it is an extension connection, and there is no partner address, so the simulated extension telephone 2143
This information is not generated from .

Here, the extension telephone group test sequence processing section 71 that has received the response information from the extension telephone group simulator section 3 refers to the state table address column. Since the state table address there is Tt -2, the state address table group in FIG. 3 and address 2 of the state table T/ are referenced. The state address table is
Among the processing programs that transition to each state, a dial tone detection program is set in the address 2 column of the state table T. Therefore, the extension telephone group test sequence process M71 starts a process of detecting a dial tone from the information sent from the extension telephone group simulator section 3. This makes it possible to test whether or not the electronic exchange 1 is operating correctly regarding outgoing calls.

A. The information next to address 1 in the event table indicates that the person to call is an extension, and the information that the phone number is 2432 is stored. These pieces of information are sent from the extension telephone test sequence processing section 71 to the extension telephone group simulator section 3, and then sent from the simulated telephone 2432.

The above state settings for telephones are performed for each simulated telephone, and a plurality of telephones are set to a certain state at the same time. At this time, it is assumed that the other party's extension telephone 2432 is set to a busy state.

The electronic exchange 1 receives information indicating the extension from the connected terminal (channel) of the extension telephone 2143 and dial information 243
2, it refers to the station data file table 78 to obtain the channel number to be connected, and refers to the state of its output terminal.

Here, if you try to connect to extension telephone 2432,
Since extension 2432, which is simultaneously simulated by extension telephone group simulator 3, is set to be in use, electronic exchange 1 returns the information of the busy sound to extension telephone 2143, which is the originator. This busy information is sent from the extension telephone group simulator section 3 to the extension telephone test sequence processing section 71.

On the other hand, the extension telephone group test sequence processing section 71 that receives the response information from the extension telephone group simulator section 3 refers to the state table address column in the same manner as described above. The next state table address is T! -1, so the state address table group in Figure 3 and our state table T
Address number 1 of / is referenced. A busy tone detection program is set in the address 1 column of the status table T. Therefore, the extension telephone group test sequence processing section 71 starts a process of detecting the busy tone from the information sent from the extension telephone group simulator section 3, refers to the "busy data" of the detection data, and sets this to the expected value. A test is performed to determine whether the electronic exchange 1 is operating correctly.

When the connection operation of the electronic exchange 1 is confirmed in this way, the next column is referred to, but in this case, since the call is busy, there is no data to be sent. Therefore, this simulated extension telephone 2143 simply refers to the address of the next event table set in the next state and moves to the next state.

Here, when A and address 2 in the event table are specified for the extension telephone 2143, the column indicating whether the extension/external line is displayed will be an external line, so the external line signal and the dialed number 3468 will be displayed. will be sent to electronic exchange l.

Then, since the exchange address is Ol, refer to the office data file table 78 to obtain the physical channel (terminal) to which trunk number 3° is connected, and find the channel of extension 2143 and this trunk number. 01 and sends the dialed number 3468 to the channel of trunk number o1. As a result, the trunk simulator section 5 obtains the dialed number 3468 from the number corresponding to number 01 of the electronic exchange 1. Also, at this time,
Since the first column indicating the type of event is "transmission," the transmission operation is first performed, and the corresponding transmission signal from the electronic exchange 1 is received as a response signal, and the detection operation is recorded in the status table. 1t is read by referring to the T/+2 column of the address.

The trunk simulator section 5 sends the received information on the trunk number O1 and dialed number 3468 to the trunk test sequence processing section 73, and also calculates the number 3468 of the other party's telephone group simulator section 6 from the information on the dialed number 3468. Connect with channel. Therefore, the electronic exchange 1 sends the ringing tone information to the dialed number 3468 via the trunk simulator section 5. At this time, the telephone exchange 1 transmits the call to the extension telephone 214 that is the originator.
The ringing tone information is also sent to number 3.

The extension telephone 2143 sends the received ringing tone information from the extension telephone group simulator section 3 to the extension telephone test sequence processing section 71.

The extension telephone test sequence processing unit 71 refers to the state table address column in address 2 of the AI event table, and determines whether the information is the state table address Tt.
-3, address 3 of state Chiful T is referenced. Then, the system enters the ringing tone information detection process shown therein, refers to the "ringing tone data" in the verification data column as an expected value, and verifies the obtained information.

In addition, the trunk test sequence processing section 73 uses the information received from the trunk simulator section 5 with reference to the event table assigned to the trunk test sequence processing section 73, and uses the expected value (verification data) in that table and the trunk simulator section. Verify by comparing with the information from 5.

On the other hand, in the other party's telephone group simulator section 6, for example, the address i of the A/event table is designated by the other party's telephone test sequence processing section 74 which controls it.
The telephone with the number 3488 is simulated in a state in which it receives from the outside line 2143. Therefore, when the electronic exchange 1 sends the ringing tone information, for example, address 3 of the status table TI is referred to, and a program for detecting the ringing tone information is started in the other party's telephone test sequence processing section 74.

Here, when the verification data is compared and verified using the expected value and the ring tone information is detected, the next state table T
2+k, for example, generates a ringtone of lifting the telephone, and further transmits data indicating a state corresponding to the phrase "moshi-moshi", for example, "oxO×
" is sent from the other party's telephone test sequence processing section 74 to the other party's telephone group simulator section 6. Then, it is sent from the simulated telephone number 3468 to the trunk simulator section 5.

As a result, this is returned to the number 2134, which is being simulated by the extension telephone group simulator section 3, which is the originator, via the telephone exchange 1. At the same time, the data "OxOx" in the verification data field is sent from the multiple telephone test sequence processing section 74 to the extension telephone test sequence processing section 71 as an expected value via the multiple parallel processing control section 76.

When the number 2134 side receives this transmitted signal “O×O×”, it executes the extension telephone test sequence processing unit 7.
Event information is received from address m of the AI event table which is the next event table from 1 to 1, and the process of detecting this cash on delivery information is performed according to the state table address.

The expected value of the verification process at this time is the multiple parallel processing control unit 7
6 as the expected value, it is determined from this that the electronic exchange 1 has transmitted correct information.

Here, the content of the transmission data can be changed to a particularly strict condition, for example, the state of the call volume can be changed to a particularly strict specification. That is, the performance limit of the pulse response speed of the electronic exchange 1 can be grasped by setting the pulse speed of the dial number to be data that is generated faster than the specified speed. Furthermore, in addition to the speed, if the shape and width of the generated waveform deviates from the specifications and is selected for the transmission data, it is possible to receive signals of any state.

You can easily determine whether to attach it or not.

Furthermore, by simulating many telephones at the same time, it is possible to place a large load on the exchange and find out its limits, and in particular, it is possible to easily set loadable conditions close to reality, including outside lines, extension lines, etc.

The verification processing by referring to the event table, comparing it with its expected value, and referring to the status table is performed in the same way for the switchboard and trunk, so that the test of the electronic exchange 1 is performed in the same manner as the actual operating state. The test shall be carried out under the following conditions.

As described above, the configuration of the simulation control unit in the embodiment is not limited to that shown in the embodiment, as various configurations can be made by combining the processor and the program. In the process, the simulation control unit controls the first . The second telephone simulator section and the trunk simulator section are set to a specific connection state, and the first . Any method may be used as long as it compares the information obtained from the second telephone simulator section and the trunk simulator section with the corresponding expected value information and determines whether or not they match.

In the embodiment, the detection of a dial tone and the detection of a ring tone are not specially stored as data in the verification data column. J', but this is a program that includes a process to detect corresponding data, and this is done by JF inputting the data into the verification data field like other verification data. Good too. Further, other expected value data may be stored in the program first in such a field.

Furthermore, the event table, status table, and call setting table do not necessarily need to be provided in the form of tables, and may be individually included in the program as data.

In the embodiment, an electronic switchboard is used as an example, but it goes without saying that the present invention can be applied to switchboards in general.

[Effects of the Invention] As can be understood from the explanation below, the present invention includes a first telephone simulator section, a trunk simulator section, a second telephone simulator section, and a simulation control section. By simulating your own telephone, trunk, and peer telephone, connecting it to a telephone exchange, dynamically capturing the movement of each part, and comparing it with expected values, you can create a system that is close to the actual usage state. Efficient testing is possible in a short time. Moreover,
Since telephones and the like are realized through simulation, it is possible to easily overload the telephone exchange with information under severe conditions, and this can be judged under actual operating conditions, allowing a clear understanding of its performance.
