Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a station data control system in an electronic exchange.

In an electronic exchange, as shown in FIG. 1, the station data necessary for exchange connection (for example, a correspondence table between subscriber numbers and exchange terminals, presence or absence of long-distance connection regulations for each subscriber number, etc.) is stored in a station data memory 120. The station data memory 120, program memory 130, temporary storage memory 140, input/output device 160, etc. are connected to the central control unit 110 via a common bus 150. The call processing program is stored in program memory 130 and executed by central controller 110. Station data necessary for the exchange process is read from the station data storage memory 120 via the common bus 150.

On the other hand, when performing maintenance and operation of the exchange, such as rewriting and reading out station data, by having the central control unit 110 execute a maintenance program, the input/output device 160 and the station data memory 1
Transfer is performed between 20 via a common bus 150. The above maintenance program is in program memory 13.
Stored at 0. However, maintenance programs have a lower priority than call processing programs, so if the load on the switch becomes large,
There is a drawback that the response of the maintenance program is slow, and therefore the rewriting and reading of station data is slow.

The purpose of the present invention is to solve the above-mentioned conventional drawbacks and
It is an object of the present invention to provide a station data control method in an electronic exchange that allows for quick rewriting and reading of station data even when the exchange is busy.

The control method of the present invention provides a storage program type electronic switching system that is equipped with a station data memory that stores station data necessary for exchange connection and performs exchange connection by referring to the station data memory. It is composed of a first station data memory and a second station data memory, and is independently equipped with a call processing central control unit and a maintenance central control unit, and a call processing program memory and the output of the first station data memory are used for call processing. A maintenance program memory, an input/output device, inputs of the first and second station data memories, and an output of the second station data memory are connected to the call processing central control unit by a common bus. It is characterized in that it is connected to the maintenance central control unit via a common bus.

Next, the present invention will be explained in detail with reference to the drawings.

FIG. 2 is a block diagram showing one embodiment of the present invention. That is, the station data memory is constituted by the first and second station data memories 220 and 221, and the same station data is written in both. The station data necessary for call processing is stored in the first station data memory 220.
, and sent to the call processing central controller 210 via the call processing common bus 250. A call processing program necessary for call processing is stored in a call processing program memory 230, and a call processing program required for call processing is stored in a call processing common bus 25.
0 is connected to the output of the first station data memory 220, a call processing program memory 230, a temporary storage memory 240, and the like. On the other hand, the inputs of the first and second station data memories 220 and 221 are as follows.
It is connected to the maintenance common bus 251, and the output of the second station data memory 221 is also connected to the maintenance common bus 251.
Connected to 1. Furthermore, the maintenance central control device 2
A maintenance program memory 231, a temporary storage memory 241, an input/output device 260, etc. are connected to the maintenance common bus 251. Writing and rewriting of station data is performed by executing a maintenance program based on input from the input/output device 260 (for example, a console). Writing of station data is performed in the first and second station data memories 220 and 2.
The same data is written to 21 at the same time. Station data necessary for maintenance is read from the second station data memory by executing the maintenance program. Since the maintenance program can be executed in parallel with call processing, processing speed is greatly improved compared to conventional methods, and station data can be quickly rewritten and read even during busy call processing times. It has the effect of

As described above, in the present invention, a call processing central control device that executes a call processing program and a maintenance central control device that executes a maintenance program are independently provided, and station data is transferred to the first and second stations. The station data necessary for call processing is stored in the station data memory, and the station data necessary for call processing is sent from the first station data memory to the common bus for call processing, and the station data necessary for maintenance is sent from the second station data memory to the common bus for maintenance. Since the same data is written to the first and second station data memories at the same time, writing, rewriting, and rewriting of station data is possible even when the exchange is busy. Possible quickly. The maintenance program is executed in parallel with call processing, greatly improving processing speed compared to conventional systems.
