Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a centralized management system, particularly to a centralized management system that enables line testing and overload testing of telephone exchange systems.

(2) Background of the technology It is well known that telephone exchange systems and data processing systems whose main components are computer central processing units are tested before they are put into actual operation. For example, if a detailed billing method is used to calculate charges for a telephone exchange system,
System overload tests are being conducted by flowing a large amount of pseudo data necessary for this method.

(3) Prior art and problems However, conventional overload tests have been performed by installing a pseudo call tester inside the telephone exchange. For this reason, when trying to generate a large number of pseudo calls continuously in accordance with reality, the structure of the pseudo call tester itself becomes extremely large and complex, and testing requires a great deal of time and effort. It was hot.

(4) Purpose of the Invention The purpose of the present invention is to use a centralized control method that enables overload tests and line tests by continuously generating pseudo calls without installing a separate tester. The purpose is to perform system management.

(5) Structure of the Invention According to the present invention, in a system in which a system such as a telephone exchange system or a data processing system is centrally managed by a central control unit, a test monitoring unit is provided for an interface unit that can be connected to the system main body. The interface unit sequentially sends a startup command to start up the interface unit, and the interface unit edits the predetermined type of pseudo data and transfers it to the next stage central control unit and stores it in its input/output device. The interface section provides a centralized management system in which the system continuously generates pseudo data in place of the system itself and can perform system overload tests and line tests until a stop command is received from the test monitoring section. be done.

(6) Embodiments of the Invention The present invention will be described below by way of embodiments with reference to the accompanying drawings.

FIG. 1 shows a block diagram of an apparatus for implementing the centralized management method according to the present invention. This device is composed of an interface section 1, a central control section 2, and a test monitoring section 3. In the illustrated embodiment, it is applied to a telephone exchange 4, which is the main body of the system, and is applied to a telephone exchange 4, which is the main body of the system. It is connected to test a system that records and saves billing information.

The interface unit 1 activated upon receiving a signal from the test monitoring unit 3 continuously generates pseudo calls until it receives a stop signal, so that an overload test is performed by the central control unit 2 of the detailed billing method regarding the telephone exchange 4. It's getting old.

The telephone exchange 4 is, for example, an international exchange, with terminal A connected to the caller side and terminal B connected to the called party side. As is well known, communication between a caller and a called party is performed by controlling a main switch frame 42 having an incoming trunk 41 and an outgoing trunk 43. A register sender 45 connected to the incoming trunk 41 via a register sender link 44 has an originating subscriber number (A-
Sub No.) and the called subscriber number (B-Sub No.) are accumulated, and the accumulated B-Sub No. activates the marker 46 and translator 47 to control the main switch frame 42 and connect the outgoing trunk 43. A necessary selection signal is sent to the other station via the terminal.

Reference numerals 48 and 49 are buffers connecting the exchange side and the central management device according to the present invention, the former being referred to as an initial entry buffer 48 and the latter being referred to as a talk entry buffer 48. The initial entry buffer 48 receives the above-mentioned A-Sub No. and B-Sub No. so-called initial entry (IE) from the register sender 45 and transfers it to the interface section 1, which will be described later. In addition, the talk entry buffer 49 receives information called answer entry (AE) when the called subscriber responds from the incoming trunk 41 via the register sender link 44, and when the call ends or when the calling subscriber stops the call midway through the call. Information in the event of a disconnection, so-called Disconnect Entry (DE), is received and transferred to the interface section 1. IE above,
AE and DE are three types of information necessary for detailed billing. In other words, it is now possible to know who made an international call, where (IE), from what time (AE), and until what time (DE). This is how your phone charges are calculated. Incidentally, not only one set of the initial entry buffer 48 and the talk entry buffer 49 are provided, but in the illustrated embodiment, a plurality of sets are provided from No. 0 group to No. n group. The interface section 1 includes the above-mentioned initial entry buffer 48, talk entry buffer 49, . . . 4
Three types of information IE transferred from 8n and 49n,
The transfer form is changed so that AE and DE can be easily edited by the central control unit 2 at the next stage. For example, it has the function of converting it to binary format.

A basic clock generator 181 provides the clocks necessary for the operation of the 8-bit general-purpose microprocessor 18.
The PIA 12 is processed along with the operation of the timer 19 that creates the timing necessary for software and hardware monitoring.
4 to the next central control unit 2. There is also an Asynchronous Communications Interface Adapter (Asynchronous Communications Interface Adapter).
Adapter (hereinafter abbreviated as ACIA) 17 is bus 1
The microprocessor 18 is connected to the data line group L from the test monitoring section 3 and the microprocessor 18.

The central control unit 2 includes a central processing unit 23, an input PIA 21 and an output PIA 22 connected via a bus 25.
The three types of information (IE, AE, and DE) edited for each call by the interface section 1 are stored in an attached input/output device 24, for example, on a magnetic tape. The central processing unit 23 is duplicated, and the two units operate synchronously to constantly collate calculation results and ensure safe operation.

The test monitoring section 3 is a monitoring device (supervisory
It consists of a processor (hereinafter abbreviated as SVP) 31 and a rotary switch 32.
The interface unit 1 is activated via the interface unit 1, and pseudo data of three types of information IE, AE, and DE required for detailed billing are continuously sent to the interface unit 1.

The SVP 31 includes a typewriter 313 into which a test pattern command, for example, a command to distinguish whether to perform a pseudo call test, an overload test, or a line test, is written, and a storage device 315 consisting of ROM or RAM according to the command. A microprocessor 314 that reads necessary test data from the ACIA 312 and transfers it to the rotary switch 32, and a PIA 311 that has an interface function with the central control unit 2 are connected to each other via a bus 316. The rotary switch 32 is configured so that its contacts 321 are sequentially switched, and the aforementioned (n+1) sets of necessary information are sequentially sent to the interface unit 1 via the data line group L.

The central management device having the above configuration operates as follows. First, a test pattern command is inputted from the typewriter 313 of the monitoring device 31 of the test monitoring section 3. For example, when performing an overload test, that is, an operation test on data up to the limit of capacity allowed by this detailed billing method, the test pattern command
Type LOADTST. After receiving this command, the microprocessor 314 checks the peripheral devices, and then
A startup preparation command is given to the interface section 1. After receiving the command, the microprocessor 16 of the interface section 1 confirms its own readiness and then transmits a preparation signal to the central control section 2, thereby completing the preparation for the overload test.

Next, the microprocessor 314 of the monitoring device 31
A large amount of pseudo data IE, AE, DE stored in advance in the storage device 315 of the ACIA 312 is read out. Also rotary switch 32
is preset to No. 0 as shown in the figure. First, the first pseudo data IE is ACIA31
2 is serially converted to rotary switch 3.
2 and the leftmost line LO of the data line group L to the ACIA 17 of the interface section 1.
ACIA 17 converts the pseudo data IE from serial to parallel, and then temporarily stores it in RAM 16 via Baba 11. The microprocessor 16 receives a signal indicating that the pseudo data IE has been stored in the RAM 16.
corrects the data IE so that it can be easily edited by the central control unit 2 at the next stage and sends it out. The pseudo data IE supplied to the central control unit 2 is transferred to the central processing unit 23 via the PIAs 124 and 21 and the bus 25, and stored in an area of the magnetic tape 24 having a predetermined address. Further, the microprocessor 18 of the interface 1 re-edits the pseudo data IE and at the same time sends a signal to the microprocessor 314 of the test monitoring section 1 via the central processing unit 23 to edit the second pseudo data AE. Give instructions to transfer. The microprocessor 31 that received this data transfer instruction
4 is the next pseudo data AE from the storage device 315.
is sent to the interface section 1 via the rotary switch 32, and the same processing as the first pseudo data IE is performed in the interface section 1 regarding the second pseudo data AE. The same applies to the third pseudo data DE. With the rotary switch 32 set to No. 0 in this manner, the pseudo data IE, AE, and DE necessary for the overload test for detailed billing are processed for the first call.

Next, the rotary switch 32 is set to No. 1, and predetermined pseudo data IE, AE, and DE for another call are processed by the interface section 1, central control section 2, and test monitoring section 3, and the same error as above is performed. A load test is performed. In this way No.n
The above predetermined pseudo data is continuously transmitted until
The overload test is performed until the stop command reaches the interface section 1. Also, the above pseudo data IE,
AE and DE may be stored in the ROM 15 of the interface section 1 in advance, and in this case, the SVP 31 sends only the activation command to the interface section 1.

Generally, the data occupation time of the interface section 1, that is, the hold time, is determined by the buffers 48 and 49 on the exchange side.
...It's shorter than the holding time of 48n and 49n, so
As mentioned above, the interface section 1 and the test monitoring section 3
Even if the line group L connecting the lines is of a serial type, the overload test using the centralized management system of the present invention can be performed more quickly than in the past. In addition, the line test can also be performed using pseudo data in the same way as the overload test described above.

(7) Effects of the Invention As described above, according to the present invention, a continuous pseudo call tester can be created using software using a microprocessor, without providing a separate pseudo call tester with a large hardware capacity as in the past. Since calls can be generated and tests can be performed, system management can be achieved centrally with small capacity and in a short time.
