Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a busy display control system for a multiprocessor automatic switching system.

Conventional multiprocessor-based automatic switching machines
The busy display information storage memory of the extension subscriber telephone is distributed and housed in the signal control processor. In addition, the office line relay boards are similarly housed in a distributed manner in the signal control processors. Naturally, therefore, the correspondence between the extension subscriber telephone and the office line relay stand needs to be established across a plurality of signal control processors. In such a case, if you try to display a busy display on the extension subscriber's phone on the central office line relay board, the signal control processor in which the central office line relay board is housed and the extension subscriber telephone you are trying to display as busy are not connected to each other. As the number of extension subscriber telephones increases and the number of signal control processors increases, it becomes necessary to transfer information to and from the signal control processors via the connection control processor.
This increases the number of times information is transferred between signal control processors, and there are drawbacks such as the need to add a new connection control processor in order to maintain the processing capacity of an automatic switching system.

An object of the present invention is to eliminate the above-mentioned drawbacks, and to simplify the busy display control of extension subscriber telephones to the office line relay board by providing a busy information storage memory, and to reduce the number of connection control processors. However, by providing a busy display information reading circuit, for example, if the busy information storage memory has memory for 10,000 extension subscriber telephone lines, it is possible to subscribe to any extension by operating the telephone key on the central office relay stand. telephone
The object of the present invention is to provide a busy display control method for an automatic exchange that allows busy display for 100 lines.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of an embodiment of the invention. A plurality of signal control processors 10 shown in FIG.
1 and a plurality of connection control processors 102, an extension subscriber telephone 103 has a signal control processor 10 and a plurality of connection control processors 102.
It is distributed and housed in 1. The busy information of the extension subscriber telephone 103 generated by the processing by the signal control processor 101 and the connection control processor 102 is sent to the busy display information storage memory 105 having memory for the maximum number of lines in the system via the information transfer bus 106. is set to Here, the busy display information storage memory 105 is provided corresponding to the signal control processor 101 that is equipped with the office line relay stand 104, and the busy display information storage memory 105 is provided for the signal control processor 101 that is equipped with the office line relay stand 104. Only a storage memory mounting area is provided so that when a central office line relay stand is newly mounted, a busy display information storage memory can also be mounted. Here, the busy display information storage memory 105 stores the latest busy states for all the lines in the system. Therefore, the central office line relay stand 10
When you input the numerical information for any 1000s and 100s from 4, the busy information of the extension subscriber telephone for 100 lines with the specified 100s and 100s numbers will be stored as busy display information. It is read out from the memory 105 and displayed on the busy indicator lamp of the central line relay stand 104.

FIG. 2 is a system diagram of a bus connected to the busy display information storage memory according to the embodiment of the present invention. In FIG. 2, an address bus 201 and a data bus 202
As a result, the busy information of the extension subscriber's telephone is set in the busy display information storage memory 203. Selector 205 using data bus 204 from central line relay board
1000s and 100s numbers are sent to the data bus 202.
When input via the data bus 20, the busy information of the extension subscriber telephones for the corresponding 100 lines is sent to the data bus 20.
6, and is displayed on the busy indicator lamp of the central office line relay stand.

As explained above, the present invention is capable of displaying the busy information of extension subscriber telephones, which are distributed and housed in each signal control processor, on the central office line relay stand without any complicated communication between the signal control processor and the connection control processor. It is possible to do this easily without having to transfer information, and it is possible to arbitrarily display the latest busy information of the extension subscriber's telephone for every 100 lines on the central office relay stand. This makes it possible for the office line relay stand operator to know the busy status of 100 extension subscriber telephone lines at any time. In addition, it is possible to reduce the number of connection control processors and reduce the traffic due to information transfer, so even if extension subscriber telephones are added for this purpose, it is necessary to newly connect them to display the busy status. This has the advantage that there is no need to increase the number of control processors unnecessarily, and has the effect of making it possible to provide a low-cost automatic exchange.

In the above description, busy information is displayed on extension subscriber telephones, but by changing the design of the embodiment of the present invention, busy information on lines such as office line trunks and trunk line trunks can be displayed. It goes without saying that it is possible to design an automatic switchboard that can easily display the information on the relay stand, and all of these are within the scope of the present invention.
