Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a test method for testing the processing ability of the entire communication processing device in a communication processing device having a line support section controlled by a processor.

In a communication processing device that has a backbone network such as a telephone network and its interface, and has communication processing functions such as converting code signals sent from many terminals into facsimile signals, it is necessary to For control purposes, a number of processor control units each having a backbone network interface for 10 lines, for example, are installed, and the signals output from these units are processed by multiple units with communication processing functions. 1 control between units
The device is configured using firmware that is controlled by a central processing unit.

Conventionally, in the test method for confirming the functionality of this type of firmware-based communication processing equipment, the communication processing equipment itself has multiple processor-controlled line support units, and in opposition to them, a A plurality of test devices are connected to the main body of the communication processing device, each of which is equipped with a plurality of line support units having a protocol, and each of which can individually generate a load for the number of backbone lines controlled by the line support units. A test method has been used in which each line handling section of a communication processing device is tested by generating a load on the number of backbone lines that it can control at once to check its functionality. Therefore, when performing a function confirmation test by applying a load (called an overload) that exceeds the load (called a standard load) for the number of backbone lines that can be controlled by the communication processing device at one time, the test device and the communication processing device itself must be The disadvantage was that many line support sections had to be provided.

The present invention aims to solve these drawbacks, and when performing a test to confirm the functionality of a communication processing device equipped with a corresponding section consisting of a large number of interfaces, such as a line compatible interface, it is necessary to A standard load is generated on the main body of the communication processing device, and a load is generated individually for each line corresponding section, so that tests can be performed by overloading the main body of the communication processing device.

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

The figure shows an embodiment of the present invention, in which 1 is a communication processing device, 2 is a test device, and 3 is a central processing unit of the communication processing device 1, in which characters are sent from a number of line handling units, which will be described later. It has functions such as converting information such as codes into facsimile signals and sending the facsimile signals to other line handling units, and monitoring the line handling units from the protocol termination status of each backbone line. Reference numeral 4 is a central processing unit of the test device 2, which transmits information such as character codes according to a predetermined test procedure to the bus interface section 10,
11 to the line compatibility test sections 12 and 13, and the character code information corresponding to the number of backbone lines that the communication processing device 1 can process at one time is sent to the central processing unit 3 of the communication processing device 1 as if it were sent to the line compatibility test sections 12 and 13. It has a function of applying a standard load to the communication processing device 1 by passing it through the bus interface section 9 as if it had come through the communication processing device 1. 5 and 6 are line corresponding parts, for example,
It accommodates 10 backbone lines, and for each backbone line, a pre-established network is established between the external device (test equipment in the case of testing) and the backbone line in order to exchange information via the backbone line. It has the function of terminating the protocol, extracting only the character code information, and sending it to the central processing unit 3, and the function of grasping the protocol termination status of each trunk line and sending it to the central processing unit 3. 7,
8 is an internal bus of the device, 9, 10, and 11 are bus interface sections that exchange information between other devices and the internal bus of the device, and 12 and 13 are line compatibility tests that load the line compatibility section of the device under test. Department.

This operation is performed as follows. The internal bus 7 of the communication processing device 1 has a direct interface with the bus interface section 9 of the test device 2, and the bus 7 and the bus 8 are connected via this bus interface section 9.
are combined. In such a connected state, the central processing unit 4 receives a standard load.

This load is applied to the central processing unit 3 of the communication processing device 1 via the internal bus 8 of the test device 2, the bus interface unit 9, and the internal bus 7 of the communication processing device 1, which are connected in a pseudo manner on the interface. It takes. In other words, for the communication processing device 1, the situation is the same as if a load call were generated via the line handling units 5 and 6, and the central processing unit 3 performs communication processing for the standard load.

Next, while the standard load is applied to the communication processing device 1, the line compatible test sections 12 and 1 of the test device 2 are
3 are connected to the line corresponding parts 5 and 6 of the communication processing device 1 facing these. However, the line support units 5 and 6 each have a different protocol on the backbone line, and the line support test unit 12 of the test equipment 2,
13 is adapted to the protocol on each backbone line. With this type of connection, the central processing unit 4 of the test equipment 2 connects to the main lines of the line support units 5 and 6 via the internal bus 8, bus interface units 10 and 11, and line support test units 12 and 13, respectively. A load is generated for each line, and a load is applied to the central processing unit 3 of the communication processing device 1.

Therefore, the central processing unit 3 of the communication processing device 1
A standard load is applied to the communication processing device main body 1 by the test device main body 2, which has a direct interface with the internal bus 7 provided between the communication processing device main body 1 and the line corresponding parts 5 and 6. A test can be performed to confirm the functionality of the communication processing device 1 by applying a load to the corresponding units 5 and 6.

As explained above, the standard load can be applied to the communication processing equipment itself, and then the load of the line support section for testing purposes can be applied via the individual units. There is an advantage that there is no need to install a unit, and that various tests on the line interface section can be easily performed by changing the standard load and the load on the line interface section.
