The figure is an explanatory diagram of a specific example of the call volume setting table.

In FIG. 1, 1 is an electronic exchange, and 2 is an electronic exchange test device. The electronic exchange test equipment 2 includes an extension telephone group simulator 2 section 3 that realizes each of a plurality of extension telephones, a switchboard simulator section 4, a trunk simulator section 5, a counterpart telephone group simulator section 6 that realizes each of the other party's telephones, and It consists of a simulator control section 7 which sets an extension telephone group simulator section 3, a switchboard simulator section 4, a trunk simulator section 5, and a counterparty telephone group simulator section 6 to predetermined operating states and exchanges information with them.

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, for a designated telephone among the simulated telephones, the amount of calls generated during outgoing calls is set in accordance with the control signal.

Control signals for setting up this call, dial information, transmission data, and various other information related to the telephone's transmitting and receiving operations are as follows:
It is given from the simulation control section 7. The extension telephone group simulator section 3 refers to the station data file 78 according to this information, finds a correspondence between a logical line address such as a telephone number, and a physical line address, and simulates a specific telephone to determine the specified telephone number. It executes operations, exchanges information with the electronic exchange 1, and receives response information from the electronic exchange 1. Various types of response information received from the electronic exchange 1 are sent from the extension telephone group simulator section 3 to the simulation control section 7.

The switchboard simulator section 4 connects input/output terminals connected to these lines in accordance with the number of switched lines of the 7FI secondary switchboard 1, and each of these terminals (or each channel) corresponds to the number of switched lines of the 7FI slave switchboard 1. It is connected to each terminal (or each channel) of the switchboard connection. Then, in response to the output signal of the electronic exchange 1, preset dial information etc. are 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 1. .

The trunk simulator section 5 has input/output terminals connected to these lines corresponding to the number of lines actually connected to the electronic exchange 1, and each terminal (or each channel) has input/output terminals connected to these lines.
are connected to each terminal (or each channel) of the trunk line connection of the electronic exchange l. 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 section 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 section 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 group simulator section 8 receives information regarding the transmitting/receiving operations of the telephones from the simulation control section 7, and according to this information, refers to the station data file 78 to establish a correspondence between logical line addresses and physical line addresses. , a specific telephone is simulated to execute specified operations, exchange information with the electronic exchange 1 via the trunk simulator section 5, and send information obtained from the trunk simulator section 5 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, multiple parallel processing control section 7
6. 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 extension telephone group simulator section 3 according to the event information, and compares and determines the response information received from the extension telephone group simulator section 3 with an expected value. Similarly, the switchboard test sequence processing section 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, and compares the response information received therefrom with the expected value. The other party's telephone test sequence processing section 74 controls the other party's telephone group simulator section 6 according to the event information, and compares and judges the response information received from the simulator section 6 with the expected value.

Extension telephone test sequence processing section 71, switchboard, test sequence processing section 72, rank test sequence processing section 73, and other party's telephone test sequence processing section 74
Each test sequence processing section includes a multiple parallel processing control section 7.
Multiple control is performed under the control of No. 6, and each performs a sacrifice hit process. The event information is stored in the event table group 76 and one dog state table 7 by each test sequence processing unit.
7. On the other hand, the station data file table 78 is a table for converting a physical channel for the switching operation of the electronic exchange 1 into a logical channel such as a connection target 7 [talk number, etc. , is stored in a magnetic disk device, etc. as internal memory, and is referred to by each simulator section to obtain a physical line address from a logical line address such as a telephone number, and is stored in each test sequence processing section as necessary. Also referred to.

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 multiplex/IC row processing control unit 76. If the result of this judgment matches the expected value,
Moving on to the next test, if they do not match, the data is sent to the multi-parallel processing control unit 76 and the status is displayed on a CRT display (not shown) or the like. 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 performs abnormality judgment from each test sequence processing unit. The result information is obtained and processing such as displaying it on a CRT display is performed.

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 to n)) provided corresponding to the physical end r of the electronic exchange l corresponds to which extension telephone number it is connected. The channel-trunk number conversion table shows that each channel (CHI (i=1 to m)) provided corresponding to the input/output terminal of the electronic exchange 1 connected to the outside line is This shows which trunk number of section 5 is connected.

Now, when a certain test type [I is specified from the keyboard (not shown), the multiple parallel processing control unit 76 controls the test type I.
The start address of the program that generates the event corresponding to -1 is expanded to each test sequence processing section including the extension telephone test sequence processing section 71 and sent to each of them.

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". , sends control information for placing the extension telephone in a calling state to the extension telephone group simulator section 3. In addition, when the content of the call means setting a condition, for example, when it is "call C-t" such as A, address 2 of the event table,
The information at address No. 1 of the call setting table C in FIG. 4 is read out, and the information is sent to the extension telephone group simulator section 3 as call volume control information for the outgoing call operation of the simulated telephone.

The extension telephone group simulator section 3 simulates a designated extension telephone 2143 into a calling state and waits for the next information. This call status signal is sent to the extension telephone 2143.
is sent to the terminal of the electronic exchange l connected to it via the input/output terminal of the electronic exchange l.
From there, information indicating the extension number and dial information of the destination are received. Note that the event information at address 1 in the AI event table does not have a switchboard address because it is an extension connection, and also does not have a game address, so these pieces of information are not generated from the simulated extension telephone 2143.

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 T/-2, the state address table group in FIG. 3 and address 2 of the state table T/ are referenced. The state address table is a processing program that transitions to each state, and the address 2 column of the state table T/ contains a dial tone detection programmer l.
, is set. Therefore, the extension telephone group test sequence processing section 71 starts a process of detecting a dial tone from the information sent from the extension telephone group simulator section 3. This allows the electronic exchange 1 to operate correctly regarding outgoing calls.
You can test whether or not you have been exposed.

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 process ffl<71 to the extension telephone group simulator section 3, and then sent from the simulated telephone 2432.

The following 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 and dial information from the connected terminal (channel) of the extension telephone 2143 +v24
32, it refers to the n 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 information on 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. Since the next state table address is T/-1, the state address table group in Figure 3 and our state table T
, address number 1 is referenced. A busy tone detection program is set in the address 1 column of the status table TI. 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 operates properly.

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 moves to the next state by referring to the address of the next event table set in the next state.

Here, when address 2 in the A/event table is specified for the extension telephone 2143, the column indicating the extension/external line is displaying an external line, so the external line call "i3." and its dial destination are number 3468 will be sent to the electronic exchange 1.

Since the exchange address is 01, refer to the exchange data file table 78 to obtain the physical channel (terminal) to which the trunk number is connected, and then
143 is connected to this trunk number 01, and the dialed number 3468 is sent to the channel of trunk number 01. 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.

At this time, the first column indicating the type of event is "Calling C-1", so the calling operation is first performed and the corresponding calling signal from electronic exchange 1 is received as a response signal. The detection operation is performed with reference to the T/+2 column of the state table address. If the dial tone is detected normally, a dial pulse will be generated next, but the field for the type of the previous event will be “Call C-1”.
”, so address 1 of call volume setting table C
A dial pulse with a call volume according to the address information is generated and sent to the electronic exchange 1.

That is, in order to set the call volume when making a call, the extension telephone group test sequence processing unit 71 calls the call volume setting table C in FIG. control information is sent to the extension telephone group simulator section 3.

As a result, a dial pulse with a call volume of specially set conditions not according to the normal specifications is sent out from the simulated telephone extension 2143, which is here transmitted to the electronic exchange l as the dialed number 3468. Ru.

In response to such a dial pulse, the electronic exchange 1
If it always operates, it will receive a normal response signal from the electronic exchange 1. Further, if the electronic exchange 1 normally accepts the pulses of such call volume, a normal signal is sent to the trunk simulator section 5. The trunk simulator unit 5 sends the received trunk number 01 and dialed number 3468 information to the trunk test sequence processing unit 73, and also sends the information of the received trunk number 01 and dialed number 3468 to the trunk test sequence processing unit 73.
From the information, number 34 of the other party's telephone group simulator section 6 is determined.
Connects to 68 channels. 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 electronic exchange 1 also sends ring tone information to the extension telephone 2143 that is the originator. The extension telephone 2143 transmits the information of the received ring tone to the extension telephone group simulator section 3.
from there to the extension telephone test sequence processing section 71.

The extension telephone test sequence processing unit 71 refers to the 1 dog status table address column in address 2 of the AI event table, and stores the information as the status table address T.
l-3, address 3 of state table T/
See. Thereupon, the system enters information detection processing for the ringing tone to be lowered, refers to the "ringing tone data" in the verification data field as an expected value, and verifies the obtained information.

On the other hand, in the trunk test sequence processing section 73,
Similarly, the information received from the trunk simulator section 5 is referred to the event table assigned to the trunk test sequence processing section 73, and the expected value (
Verification data) is compared with information from the trunk simulator section 5 for verification. Here, if the electronic exchange l is not operating normally due to a difference in the dialed number of the other party, the address of the other party, etc. in response to the dial pulse set for the special call volume, an abnormal condition will be detected. Ru.

Further, in the other party's telephone group simulator section 6, for example, the address i of the A/event table is specified by the other party's telephone test sequence processing section 74 which controls it.
The telephone with the number 3468 is simulated in a state where it receives from the outside line 2143. Therefore, when the electronic exchange 1 sends out ring tone information, address 3 of the status table T, for example, is referred to, and a program for detecting ring tone information is started in the other party's telephone test sequence processing section 74. Here, if the electronic exchange 1 does not operate normally in response to the dial pulse set for the special call volume, a redundant state that is not detected by the trunk test sequence processing section 73 is detected.

Here, if the connection operation of the electronic exchange 1 is correct, the verification data is compared and verified using the expected value, and the ring tone information is detected. At this time, the next state table T2+k is referred to, for example, a ring tone is generated when the telephone is picked up, and furthermore, 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 1ffi5.

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 electronic exchange 1. At the same time, data "oxOx" in the verification data field is sent from the other party's 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.

Is; The 2134 side receives this transmitted signal “0XOX”
When receiving the event information from the address m of the AI event table, which is the next event table, from the extension telephone test sequence processing unit 71,
Processing to detect this incoming call 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
Since "XQX" is received as the expected value from 6, it is determined that the electronic exchange 1 has transmitted correct information.

Here, particularly strict conditions can be set in stages for the contents of the call volume in the call volume setting table C. for example,
The pulse speed of the dial number can be generated as data that is faster than the specified speed, or the pulse width can be changed, and thereby the performance limit of the pulse response speed of the electronic exchange 1 can be grasped. In addition to the speed and width, if the shape of the generated waveform, etc. that deviates from the specifications is easily selected in the transmission data, it becomes easy to determine what state of signals will be accepted. Can be judged.

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 process of referring to the event table, comparing it with its expected value, and referring to the status table in 1-1 below is performed in the same way for the switchboard, so that the test of the electronic switchboard 1 is performed in the same manner as in the actual operating state. Tested in the state.

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 short, the simulation control unit performs 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 example, the detection of dial tone and the detection of ring tone are not specially stored as data in the verification data column (this is done by inserting processing to detect the corresponding data in the program). However, these data may be entered into the verification data column in the same way as other verification data.

Alternatively, other expected value data may be built into the program that writes it into such a column.

Further, the event table, status table, and call rate 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 electric 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-1-, in the present invention, the first telephone simulator section, the trunk simulator section, the second telephone simulator section, and the simulation control section are provided. It has the ability to simulate own telephones, trunks, and counterpart telephones.
By connecting to a telephone exchange and dynamically capturing the movement of each part and comparing it with expected values, it is possible to perform efficiency tests in a short time under conditions close to actual usage conditions. Furthermore, since telephones, etc. are realized through simulation, it is possible to set the call volume under strict conditions for the telephone exchange, and this can be used to determine the line load limit value etc. in the actual operating state, so that the performance of the telephone exchange can be evaluated. Can be clearly understood.
