JPH0583756A - Private branch electronic exchange - Google Patents

Abstract

PURPOSE:To enhance the processing capability of a central controller. CONSTITUTION:The private branch exchange is provided with a selector 100 selecting either enable information 110 for storing accommodated position or disable information 113 and outputting the selected information, a selector 101 selecting either an address 111 for storing the accommodated location or accommodation location information decided by a counter 103 and outputting the selected information, a memory 102 storing outputs from the selectors 100, 101, a gate 106 outputting the disable information 113 based on the output from the memory 102 and on dial information 105, and a memory 104 outputting accommodated location data based on the accommodated location information from the counter 103 and the disable information 113.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic private branch exchange,
In particular, it relates to an electronic private branch exchange that controls a calling party.

[0002]

2. Description of the Related Art In the conventional caller control system in an electronic private branch exchange, each subscriber control unit that interfaces with a subscriber's telephone detects the call origination of the subscriber, and the central control unit controls all calls. The calling information from the subscriber control unit is read out in order and fetched into the central control unit for control.

[0003]

In the conventional call detection control system in the electronic private branch exchange, the central control unit completely collects the call information detected by each subscriber control circuit interfacing with the subscriber side at regular time intervals. There is a problem in that the central control unit needs to perform useless processing because the fetching control is performed and the uncalled information that does not need to be fetched is also fetched, which lowers the processing capability.

[0004]

The electronic private branch exchange of the present invention is determined by a first selector for selecting and outputting permission information and non-permission information of accommodation position storage, and an address and counter of accommodation position storage. A second selector for selecting and outputting the stored accommodation position information, a first memory for storing the outputs from the first and second selectors, and a first memory for storing the outputs.
And a second memory for outputting accommodation position data based on the accommodation position information from the counter and the disapproval information.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention, and FIG. 2 is a block diagram for explaining the operation of the present embodiment.

In this embodiment, in FIG. 1, the selector 100 for selecting and outputting the permission information 110 and the disapproval information 113 for storing the accommodation position, the accommodation position information determined by the address 111 and the counter 103 for storing the accommodation position. And a selector 111 for selecting and outputting
A memory 102 for storing the output from
Information 113 that is good for the output from the call and the call information 105
And a memory 104 that outputs the accommodation position data from the accommodation position information from the counter 103 and the disapproval information 113.

Next, the operation of this embodiment will be described.

From the subscriber control units 204 and 205 to the control PC
When the calling control information for each subscriber is input from the memory 102 from the memory 102, the gate 106 to which the calling information 105 in the M signal 208 is input to one side is a non-permission signal 113 for storing the accommodation position.
Is output. In the case of a new call, the accommodation position information of the accommodation position counter 103, which is determined depending on the calling party, is stored in the memory 104. In the case of a new call, the calling control information stored in the memory 102 is such that the accommodation position information is stored in the accommodation position storage permission signal 110, and then the accommodation position storage disapproval signal 113 is output from the selector 100. Remember. The same accommodation position information is stored in the memory 104 until the control unit 202 rewrites the non-permission signal 113 into the permission signal 110.
To be stored in. The accommodating position presence / absence data 108 and the accommodating position information 109 from the gate 107 stored in the memory 104 are periodically read by the control unit 202 and processed by the calling subscriber.

In this way, in the exchange 200 of FIG. 2, the subscriber control units 204 and 205 are connected to the telephone 209,
A call from 210 is detected, and control PCM is used as call information.
The call control unit 203 is notified via the signal 208.
The control unit 202 can synchronously read the calling information from the calling control unit 203 and perform processing for connecting the calling subscriber to the time divisional switch 201.

[0011]

As described above, according to the present invention, only the calling subscriber is automatically detected among all the subscribers, and the central control unit performs various processes only for the calling subscriber. This has the effect of eliminating wasteful processing and improving processing capacity.

Claims (2)

[Claims] 1. A means for generating a signal in which the subscriber's accommodation position information is stored according to each subscriber's calling information in a control PCM signal transmitted at a timing corresponding to the subscriber's accommodation position, and a central control. An electronic private branch exchange comprising: means for stopping the storage operation of the accommodation position information until it is released by a device; and means for storing the accommodation position information by the signal. 2. A first selector for selecting and outputting accommodating position storage permission information and non-permission information, and a first selector for selecting and outputting accommodating position storage addresses and accommodating position information determined by a counter. Two selectors, a first memory that stores the outputs from the first and second selectors, and a gate that outputs the disapproval information based on the output from the first memory and the calling information. An electronic private branch exchange comprising: a second memory that outputs accommodation position data based on the accommodation position information from the counter and the disapproval information.
