Abstract

PURPOSE:To freely change classifications and the number of resources without changing a control program at all by temporarily storing the classification of the resource set in each mounting position of a mounted board in a resource management table and using the table to execute the actual test call processing of an exchange. CONSTITUTION:When a resource 4 having a classification code 1 is required, an address pointer 300 of an address pointer table is read, and the area where information of the group of resources having the classification code 1 is stored in a classification code-classified mounting position table is specified by the address pointer 300. Respective state flags of the resource group (mounting position group) having the classification code 1 are successively checked to reserve the resource 4 in the mounting position which is not used, and a time switch 11 is controlled to connect an objective line to the resource set to the mounting position, thus completing preparation for tone signal reception.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a pseudo call tester for testing the operation of switching equipment, and in particular, the present invention relates to a pseudo call tester for testing the operation of switching equipment, and particularly for efficiently using multiple types of resources for receiving various tone signals sent from switching equipment. The present invention relates to a resource management device for a pseudo call tester that is managed and operated in the field.

[Prior Art] Generally, a pseudo call tester is connected to an exchange and used.
This is a device that tests the connection quality, connection stability, etc. between each line of the exchange by sending out a large number of simulated test calls to the exchange. Generating a test call to the exchange means
Specifically, it involves exchanging a wide variety of signals between the exchange and the pseudo-call test equipment. Among the signals exchanged are the ring tone (RGT) sent from the exchange, the busy tone (
It also includes various tone signals such as BT), ringback tone (RBT), and dial tone (DT). Generally, these various tone signals are received by a tone receiver called a dedicated resource corresponding to each tone signal. Therefore, a single pseudo call tester usually incorporates a plurality of resources.

If the number of lines that the pseudo call tester can simultaneously test is m, then ideally the number of resources incorporated into the pseudo call tester is m for each type of tone signal.
In consideration of economics and the simultaneous test call processing ability of the pseudo call tester, it is common to design fewer than m.

Now, once the exchange to be tested has been determined, and the test call processing capacity specifications and test specifications (test conditions, test content, etc.) of the pseudo call test equipment have been determined, it must be incorporated into the pseudo call test equipment. The minimum type and number of resources are uniquely determined.

Therefore, conversely, once the type and number of resources are determined, the test call processing capacity of this pseudo call tester and the upper limit of the test specifications are determined.

[Problem to be solved by the invention] However, the type of exchange to be tested is changed, service functions of the exchange are added, or
When the test specifications are changed, the pseudo call test equipment incorporating the types and numbers of resources described above cannot cope with the change, and in some cases, it is required to change the types and numbers of the incorporated resources.

Conventionally, when such a situation occurs, the type and number of resources are changed in hardware, and at the same time, the control program written in the storage unit is changed.

However, there is a problem in that rewriting the control program every time the type and number of resources is changed requires a great deal of effort, time, and cost.

In order to solve this problem, it is possible to incorporate resources of a type and number suitable for all possible tests into the pseudo call test equipment from the beginning, but if a large number of resources are incorporated from the beginning like this, However, there is a problem in that the manufacturing cost of the pseudo call tester increases significantly.

The present invention was made in view of these circumstances, and
By storing the types of resources installed at each mounting position on the mounting board in the -H resource management table and performing actual test call processing using this resource management table, the , the type and number of resources can be changed freely without making any equivalent changes to the control program, changes in the exchange to be tested and changes in test specifications can be immediately dealt with, and faulty resources can also be detected, thus reducing manufacturing costs. It is an object of the present invention to provide a resource management device for a pseudo call tester that can greatly expand the scope of application.

[Means for Solving the Problems] In order to solve the above problems, a resource management device for a pseudo call tester according to the present invention is connected to each line terminal of an exchange via a line interface, and provides testing to each line terminal. A pseudo call tester that outputs a call, receives various tone signals sent from each line terminal on the corresponding type of resource, and tests the operation of the exchange by at least checking the tone signals received on each resource. , a mounting board on which a plurality of resources are detachably mounted, a setting switch group consisting of a plurality of setting switches for setting whether or not to mount each resource for each mounting position of this mounting board, and each resource. a resource management table having an area for storing a type code attached to the board and indicating the type of the resource, and a type code of the resource mounted at the corresponding mounting position for each mounting position of the mounting board; type code reading means for reading the type code of each resource via each mounting position of the mounting board; switch state reading means for reading the switch state of each setting switch of the setting switch group prior to sending out a test call; and type code reading means. Type code setting means stores the type code at each mounting position read by the means in the area of the corresponding mounting position of the resource management table, and the switch state reading means sets the resource implementation and the type code reading means stores the type A failure code setting means is provided for storing a failure code in the area of the corresponding mounting position of the resource management table when there is a mounting position where the code was not read, and various types of Resources for receiving tone signals are allocated.

[Operations] According to the resource management device of the pseudo call tester configured in this way, each resource is assigned a type code indicating the type of the resource, and a mounting board to which multiple resources can be attached is attached. , a group of setting switches for setting whether or not to mount a resource at each mounting position of the mounting board, and a resource management table that stores the type code of each resource mounted at each mounting position of the mounting board. .

When the power is turned on, initial processing is performed, and the type code of the resource mounted at the corresponding mounting position is sequentially read out through each mounting position of the mounting board and stored in the area of each mounting position in the resource management table. They are stored sequentially. Naturally, it means that no resource is mounted at the mounting position where the type code is not read, or the resource at the corresponding mounting position is malfunctioning.

At the same time, the status of each setting switch in the setting switch group is also read, and if the type code is not read from the corresponding mounting position even though the setting switch indicates that the resource is installed, it means that the glue source at the corresponding mounting position is malfunctioning. It is determined that the failure code is present, and a failure code is written in the area of the corresponding mounting position in the resource management table.

Therefore, using this resource management table, it becomes possible to automatically receive various tone signals transmitted from the exchange using resources corresponding to the type of tone signal.

[Example] An example of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the main parts of a pseudo call tester incorporating a resource management device according to an embodiment. This pseudo call tester is composed of a type of microcomputer, and the CPU (Central Processing Unit) monitors and controls the operations of various electronic components. That is, C.P.
U1 is a mounting board shown in FIG. 2 on which a memory 3 for storing fixed data such as a control program and variable data such as a resource management table, and up to 16 resources 4 are removably attached via a CPU path line 2. 5. Each mounting position 5a numbered from 1 to 16 on this mounting board 5
Each switch state of the setting switch group 6 consisting of 16 setting switches 6a numbered from 1 to 16 for the operator to set whether or not the resource 4 is mounted at the corresponding mounting position. The input port door where is entered,
A line interface 10 connected to each line terminal 9 of the exchange 8 to be tested, a time switch 11 inserted between this line interface 10 and each mounting position 5a of the mounting board 5, etc. are controlled.

As shown in FIG. 2, the mounting board 5 has 1 to 16
Various resources 4 are detachably attached to the mounting positions 5a numbered.

Then, each resource 4 indicates the type of the resource (
Five types of type codes 4a, 1) to (5), are attached. Specifically, a type code 4a is stored in a memory provided in each resource 4, and when a type code transmission command is input from the CPUI, for example, the own type code 4a is stored.
Return a to the CPUI. Each resource 4 can receive a tone signal of a type that matches its own type code 4a among the various tone signals inputted from the exchange 8 via the line interface 10 and time switch 11, and transmits the received information to the CPU It has the function to send to. Note that the type code 4a in (8) in the figure indicates a type code that has not yet been registered in the control program, and indicates that the resource 4 installed at the No. 9 mounting position 5a is a failed resource. Further, it is shown that no resource 4 is mounted at the 11th and 12th mounting positions 511 shown by diagonal lines.

Furthermore, the mounting board 5 itself can be easily removed from the pseudo call tester as shown in the figure.

FIG. 3 is a schematic diagram showing the setting switch group 6. As shown in FIG. 1
Only the 1st and 12th setting switches 6a are opened,
All other setting switches 6a are shown to be turned on. That is, the operator selects the 11th and 1st mounting boards 5.
This indicates that the resources 4 have been installed in all mounting positions 5a except for the second mounting position 5a.

In addition to the control program described above, the memory 3 includes:
A resource management table is formed of three tables: a mounting position table 12a, an address pointer table 12b, and a mounting position table by type code 12c, as shown in FIG.

Specifically, the mounting position table 12 shown in FIG.
Type code 4 of the resource 4 mounted at the corresponding mounting position 5a for each mounting position 5a of the mounting board 5 is shown in a.
An area for storing a is formed. Also, the same figure (C)
The type code-specific mounting position table 12c shown in FIG. 1 stores the mounting positions of resources 4 of the same type code in order, and also stores status flags indicating the current usage status of each resource 4 belonging to the same type code. Therefore, each status flag is cleared to 0 before actually starting a test on the exchange 8. Furthermore, the same figure (b)
The address pointer table 12b shown in FIG. 1 stores the start address pointer of the corresponding type code in the type code mounting position table 12c for each type code 4a of 1 to 5. Note that the address pointer is 0.
If a type code exists, it indicates that the resource 4 with the corresponding type code is not mounted on the mounting board 5.

When the pseudo call tester is powered on, the CPU performs a process of setting the installation information of the resource 4 in the resource management table according to the control program stored in the memory 3 according to the flowchart of FIG. It is composed of

That is, in S (step) 1, the mounting position pointer n is set to the initial value 1. Next, at 82, the switch state of the n-th setting switch 6a indicated by the mounting position pointer n of the setting switch group 6 is read via the input port door. And S
If the switch status read in step 3 indicates on, S
Proceed to step 4, and move to n indicated by the mounting position pointer n of the mounting board 5.
Type code 4 for resource 4 at the th implementation position 5a
It sends a transmission command of a and reads the type code 4a transmitted from the corresponding resource 4.

Then, in S5, if the type code is successfully read from the corresponding resource 4 within a predetermined time, the process proceeds to S6, where it is confirmed that the read type code is a normal type code registered in advance. Then, in S7, the read type code 4a is added to the mounting position table 12 in the resource management table.
Store it in the area of the nth mounting position of a.

Since the process of storing the type code 4a of the resource 4 for one mounting position 5a in the mounting position table 12a has been completed, 1 is added to the mounting position pointer n in S8. When it is confirmed in S9 that the mounting position pointer n after the addition does not exceed 16, which is the total number of mounting positions 5a on the mounting board 5, the process returns to S2, and the setting switch group 6 specifies the mounting position pointer n after the addition. Check the switch state of the setting switch 6a corresponding to the number.

If the corresponding setting switch 6a is in the OFF state in S3, it is determined that the resource 4 is not installed in the n-th mounting position 5a, and in S10, the area of the n-th mounting position 5a in the mounting position table 12a is Store unimplemented code (0) in .

Furthermore, if the type code 4a is not returned within a predetermined time in S5, or if data completely different from the normal type code is returned in S6, the corresponding resource 4 is determined to be malfunctioning, and S11 At this point, the resource failure code (9) is stored in the area of the corresponding mounting position 5a of the mounting position table 12a.

Therefore, in S9, all the mounting positions 5a of the mounting board 5 are
When the process of storing the type code 4a of the resource 4, the unimplemented code, and the resource failure code in the mounting position table 12a is completed, in S12, a process of creating a mounting position table 12C by type code is performed. That is, the resources 4 are grouped according to the same type code, and the mounting position numbers are stored in address order. Note that a separator is inserted at the address position between the mounting positions of adjacent type codes to prevent the mounting positions of different type codes from being confused.

When the creation process of the mounting position table 12c by type code is completed, in 813, the address pointer table 12b is created.
Execute the creation process. That is, for each type code, an address pointer indicating the start address of the mounting position of the corresponding type code in the type code mounting position table 12c is stored.

This completes the process of setting each data to the resource management table consisting of the mounting position table 12a, the address pointer table 12b1 and the type code-specific mounting position table 12c. Note that FIG. 4 shows the contents of each table when each resource 4 and each setting switch 6a are installed and set as shown in FIGS. 2 and 3.

When the setting process for the resource management table is completed,
Actual test call processing for the exchange 8 is executed according to the arrows in the control program block diagram shown in FIG.

That is, when the test call processing program 21 of the pseudo call test device requires the resource 4 of the type code (1), for example, based on the output result of the line interface scanning program 22, first, the resource 4 of the type code (1) is set to 200 of the address pointer table 12b in FIG. The address pointer 3 (10) of the address is read, and from this address pointer 300, the area where the information of the resource group of type code (1) in the type code-specific mounting position table 12C is stored is specified. Next, the type code-specific mounting position Starting from address 300 in table 12c, each status flag of the resource group (mounting position group) with type code 1 is checked sequentially, and it is confirmed that, for example, the 8th mounting position 'source 4' is unused. The call processing program 21 sets the status flag of the corresponding mounting position 5a to 1 to secure the resource 4 of the eighth mounting position, and controls the time switch 11 to move the target line to the eighth mounting position 5a. It connects to the attached resource 4 and completes preparations for receiving tone signals.

On the other hand, the reception result scanning program 23 for resource 4 refers to the mounting position table 12c by type code and
The test call processing program 21 scans the received results and transmits the results to the test call processing program 21. At this time, the reception result scanning program 23 of the resource 4 monitors the time of the data transfer request flag of each resource 4, and if there is a resource 4 for which the data transfer request flag is not set for a certain period of time or more, an alarm can be issued. can. Further, the status flag is set to 2, which means failure. If a failure occurs while using the relevant resource 4, this fact can be notified to the test call processing program 21 so that the process can be interrupted or another resource 4 can be secured.

In this way, even if there is a faulty resource 4 among the installed resources 4 when the pseudo call tester is powered on,
Alternatively, even if the resource 4 fails while actually testing the exchange 8, the processing capacity (speed) will decrease somewhat, but the test itself can continue to be executed without interruption.

According to the resource management device configured in this way, even if the scale of the exchange 8 to be tested, the test specifications, etc. change, and the types of required resources 4 and the number of each type change. , attach the changed types and number of resources 4 to each mounting position 5a of the mounting board 5 in random order,
It is sufficient to turn on each setting switch 6a corresponding to the number of the mounting position 5a where the resource 4 is installed. When the pseudo call tester is powered on, it is determined whether or not a resource 4 is mounted at each mounting position 5a of the mounting board 5, and if so, the type code 4a of the resource 4 is stored in the resource management table. Note that even if the resource 4 is installed, the fact that it is out of order is stored.

In actual test call processing, the implementation position of resource 4 and the type code 4a are determined via the resource management table.
can be identified. Therefore, even if the type and number of resources 4 are changed within a predetermined range, such as 16, there is no need to change the control program at all.

Therefore, each resource 4 can be provided as an option so that the user can purchase the resource 4 as needed, which reduces the manufacturing cost of the entire pseudo call tester and allows the user to purchase only the necessary resources. A large number of resources that you can purchase and may not use all of them 4
Compared to purchasing a pseudo call tester with built-in
Costs can be significantly reduced.

Note that the present invention is not limited to the embodiments described above. That is, depending on the control program, the number of resources that can be attached to a mounting board is not limited to 16, and the number of mounting boards is not limited to one.

[Effects of the Invention] As explained above, according to the resource management device for a pseudo call tester of the present invention, the type of resource installed at each mounting position of the mounting board is temporarily stored in the resource management table, and the resource The management table is used to perform actual test call processing on the exchange. Therefore, the type and number of resources can be freely changed within the allowable range of the mounted board without changing the control program in any way, so changes in the exchange to be tested and changes in test specifications can be dealt with immediately. Furthermore, since a group of setting switches operated by the operator is also used, faulty resources can be reliably detected and reliability can be improved.

Therefore, the entire pseudo call test machine can be created at low manufacturing cost.
Moreover, it becomes possible to greatly expand the scope of application.
