BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic tester of an electronic exchange for performing an operation verification test of a private branch exchange such as a PBX which is a processor.

[0002]

2. Description of the Related Art Conventionally, when conducting an operation verification test with an electronic exchange such as a private branch exchange such as a PBX, a signal at an interface point when a human performs a terminal operation is simulated by an instruction from the tester main body, and Is performed by verifying the operation of the electronic exchange.

The procedure to be simulated is given from the console or file of the tester body, and the execution control sends an instruction to the interface card according to the procedure data. At that time, the execution conditions such as the originating side and the terminating side terminal and the calling interval are set before the execution.

Therefore, in the conventional automatic tester, the terminal on the calling side and the terminal on the calling side must be set before the execution of the sequence, which imposes a load close to the actual operation of the electronic exchange (realistic). Load verification) or a load several times higher than the actual load (overload test), it is not possible to use all terminals evenly when verifying system-like operation. Since it is executed in the same way, there are drawbacks that different calls do not overlap and the load time cannot be changed randomly for each call. As a result, there is a drawback in that it is not possible to carry out a load test close to the actual operating state or a quantitative overload test.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows an example of system configuration in which the automatic tester of the present invention is incorporated in an electronic exchange.

That is, the electronic exchange 1 has a built-in terminal control card section 2 and a central processing card section 3 for controlling the terminal control card section 2. The terminal control card section 2 has a plurality of terminal control cards 4, It consists of ... The terminal control card 4 includes a terminal 5 such as a telephone, an office line, and a private line 6
Are connected. Each of the terminal control cards 4, ... Is connected to the central processing card unit 3 via a control highway 7.

On the other hand, the automatic tester 8 has the terminal control card 4
Interface card 9 connected to the control highway road 7 via the interface, or interface card 10 directly connected to the control highway road 7, the central control unit 1
1, a console 12, and an external storage device 13.

The console 12 is equipped with a keyboard for inputting various control commands to the central control unit 11, a display for outputting the test results of the electronic exchange 1 in the central control unit 11, and the like.

When performing an operation verification test, the automatic tester 8 simulates a signal at an interface point when a human performs a terminal operation according to an instruction from the central control unit 11, and indicates the operation of the electronic exchange 1 in response to the signal. It is done after verification.

The procedure to be simulated is given from the external storage device 13 composed of a floppy disk or the like, and the execution control sends an instruction to the interface cards 9 and 10 according to the procedure data.

A table used for generating a random call is stored in the external storage device 13. For example, an execution procedure data table 14, as shown in FIGS. 2A, 2B and 2C, It is composed of a state management table 15 and a database table 16.

The execution procedure data stored in the execution procedure data table 14 includes candidate terminal port numbers (plural).
And the sequences they execute, such as off-hook, dial, talk, and on-hook.

The state management table 15 stores a terminal number (PN) and a dial number (DN) which are subject to restrictions (locking) for prohibiting outgoing / incoming calls so that the busy state does not occur. Terminal number (P
N) A state table 15a and a dial number (DN) state table 15b for storing the state of dials. The database table 16 is a terminal information table 16a and a dial number (DN) information table 16
b, the group information table 16c.

In the terminal information table 16a, the terminal type and dial number (DN) are registered corresponding to the terminal number (PN). As the terminal type, standard telephone (STT), multi-function telephone (HDT), etc. are stored. A multifunction telephone is a telephone that incorporates software and hardware that allows one telephone to have multiple dialed numbers.

For example, the terminal P0 is a multi-function telephone, has three dial numbers D0 to D2, and
1 and D2 are the same as the dial numbers of the other terminals P1 and P2. The other terminals P1, P2, P3 are general standard telephones, and have telephone numbers D1, D2, D3, respectively.

Dial number (DN) information table 16b
The group type associated with the dialed number is registered in. As the group type, multi-line service (MLT) and data (NON) indicating that group registration is not set are stored. The multi-line service (MLT) is one of the services of an electronic exchange that allows a call to a plurality of terminals and a response from any of them. For example, dial number D
1 and D2 are multi-line services, and dial numbers D0 and D3 are not set for group registration.

The group information table 16c stores a terminal number (PN) for each dial number that can receive the multi-line service. For example, terminals P0 and P1 are grouped for dial number D1,
The terminals P0 and P2 are grouped for the dial number D2.

The tables 16a to 16c in the database table 16 are chained and constructed so that necessary information can be read out using the terminal number (PN) as a key.

The execution control uses the concept of an event in order to realize parallel execution of the same procedure. An event is a unit for managing from the start to the end of one call, and is generated by detecting a calling command from the execution procedure data, and disappeared by the end command. Each event has a command (step) according to the state management table 15.
Up to or being managed.

The execution control realizes the parallel execution of the sequence by registering the event and step to be executed next in the execution queue, and taking out from the execution queue and executing the sequence. FIG. 3 shows a terminal number (PN) state table 15a and a dial number (DN) state table 15b in the process of executing steps in one event.
Shows the state change of.

The execution control is performed by searching the terminal number (PN) state table 15a and the dial number (DN) state table 15b when selecting the calling terminal and the dial number of the other party at the time of calling and dialing during this event. By making a decision, it is possible to prevent double use of the terminal or failure of the call due to busy. For the talk command, a random time is generated by a certain function, and this is set in a timer (not shown) to secure the talk time.

Next, the operation in such a configuration will be described. For example, now, the console in the automatic tester 8 gives an instruction for an outgoing test. Then, the central control unit 11 outputs an instruction to the electronic exchange 1 via the interface card 9 in accordance with the execution procedure read from the external storage device 13, so that the electronic exchange 1 can receive the terminal 5, the local line, and the private line 6
To simulate the transmission test.

For example, as an execution procedure, an off-hook command (calling command) of the terminal P3, a dial command, a talk command,
A case where the on-hook instruction (end-of-line instruction) is read from the execution procedure data table 14 will be described.

That is, first, when the off-hook command of the terminal P3 is read from the execution procedure data table 14 as the execution procedure data, the central control unit 11 determines that the terminal P3 is the standard telephone (STT) from the terminal information table 16a of the database 16. , The dial number D3 is read.

Then, the central controller 11 sets the storage state of the terminal number state table 15a to the idle state (IDL) for the terminals P0 to P2 as shown in FIG. (LOK). Further, as shown in FIG. 3B for the storage state of the dial number state table 15b, the dials D0 to D2 are in the idle state (ID
L), and the dial D3 is disabled (LOK).

Further, the data indicating the off-hook of the terminal P3 from the central control unit 11 is the interface card 9,
It is output to the central processing card unit 3 via the terminal control card 4 and the control highway road 7. As a result, the central processing card unit 3 accepts a call from the central control unit 11 and outputs a dial request signal to the central control unit 11.

Then, the central control unit 11 reads the dial command from the execution procedure data table 14, and the terminal number status table 15a and dial number status table 1
5b is searched to check the empty state. Then, the dial for the vacant terminal is selected from the frequency or terminal number state table 15a. In this case, the dial D1 is selected.

Thus, from the dial number information table 16b of the database 16, the dial D1 is assigned to the terminal P0,
It is read that it is a multi-line service (MLT) for P1. Then, the central control unit 11 sets the terminal P2 to the idle state (IDL) as shown in (c) of FIG.
0, P2, and P3 are set to the unusable state (LOK).

As shown in FIG. 3D, the dial number status table 15b is stored in the dial D0,
D2 is set to an idle state (IDL), and dials D1 and D3 are set to an unusable state (LOK).

The dial D from the central control unit 11
1 is output to the central processing card unit 3 via the interface card 9, the terminal control card 4, and the control highway path 7. As a result, the central processing card unit 3 accepts the dial D1 from the central control device 11, performs the dial number reception, the number translation, the busy test, and the dial D1.
To the central control unit 11 via the control highway 7 and the interface card 9.

By this calling signal, the central control unit 11
Reads a talk command from the execution procedure data table 14 and outputs a response signal to the central processing card unit 3. With this response signal, the central processing card unit 3 detects the response,
Control the call start. At this time, a call equivalent to the call between the terminals P3 and P1 is performed.

In this case, the central control unit 11 puts the terminals P0 and P2 into the idle state (IDL) and uses the terminals P1 and P3, as shown in FIG. 3E, in the storage state of the terminal number state table 15a. It is disabled (LOK). Further, as shown in (f) of FIG. 3, the storage state of the dial number state table 15a sets the dials D0 and D2 to the idle state (IDL) and sets the dials D1 and D3 to the unusable state (LOK).

After the lapse of a predetermined call time, the central control unit 11 reads the on-hook command from the execution procedure data table 14 and outputs an end signal to the central processing card unit 3. The central processing card unit 3 controls the call disconnection by this end signal.

In this case, the central control unit 11 sets the terminals P0 to P3 in the idle state (IDL) in the storage state of the terminal number state table 15a as shown in FIG. The memory state is shown in FIG.
As shown in, dials D0 to D3 are set to the idle state (ID
L).

As described above, the necessary items of the data set in the electronic exchange to be tested are built in as a database, and when the execution control is performed based on this database and the execution procedure data describing the procedure, The state management table is executed while vacant management is performed, the time sharing function using the execution queue is used for parallel processing, and the calling interval is set to the value generated by the function at the time of execution. As a result, the calling terminal, the dial number of the calling party, and the call duration can be dynamically set at the time of execution.

Therefore, the test conditions are dynamically changed during the execution of the test, that is, the calling side is dynamically changed,
Since the destination terminal is selected, and the random call interval and the call duration are set, it is possible to perform a load or quantitative overload test close to the actual operating state of the electronic exchange.
