Abstract

PURPOSE:To use all subscriber line-accommodated positions for an actual subscriber by using a general subscriber line effectively as a pseudo call line. CONSTITUTION:A central controller detects two idle general subscriber lines among subscriber lines controlled by a channel control circuit (step 1), interrupts a loop of a line circuit corresponding to the subscriber line so as not to give effect on the detected subscriber lines only during the operation of the exchange operation normality monitor function started/stopped periodically (step 2) to monitor the exchange operation normality (step 3). The loop of the line circuit interrupted in the step 2 is generated (step 6) when the monitor is stopped.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switching operation normality monitoring system for an electronic exchange.

[0002]

2. Description of the Related Art Conventionally, a transmission line and a reception line for generating a pseudo call for monitoring the normality of a switching operation have an accommodating position and a telephone number (telephone number) in a communication line that can be used as an actual subscriber. No.) is exclusively assigned, and subscriber data is created using these as pseudo outgoing lines and pseudo incoming lines. Then, the central control unit of the electronic exchange sets the transmission line accommodating position, the reception line accommodating position, and the transmission line sending telephone number (incoming line telephone number) for each speech path control circuit having the switching operation normality monitoring function. Was issued and the start / stop request for the replacement operation health monitoring was periodically made.

[0003]

In the above-mentioned conventional switching operation normality monitoring method, since the accommodation position and the telephone number that can be used as an actual subscriber are occupied, a large electronic device having a large number of communication path control circuits is used. In the exchange, many subscriber accommodating positions and telephone numbers are used only for the purpose of monitoring the normality of the exchange operation, so that the actual accommodating number of subscribers is reduced.

[0004]

According to the switching operation normality monitoring method of the present invention, the central line is notified of the transmitting line accommodating position, the incoming line accommodating position, and the transmitting line sending telephone number, and the periodical operation is performed periodically. Receiving a start / stop request, a pseudo call is generated from the transmission line accommodating position, the call processing program is started, and a series of exchange operations from call origination to number reception, termination, response and disconnection are monitored. However, when an abnormality is detected, in the switching operation normality monitoring method of the electronic exchange having the speech path control circuit having the function of notifying the content of the abnormality, the two unused subscriber lines controlled by the speech path control circuit are A switching operation normality monitoring function that detects a general subscriber line and periodically starts and stops it is operated only when the normal line is detected so as not to affect the detected subscriber line. Cut the loop of the circuit, which is configured for exchanging operation health monitoring.

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

FIG. 1 (a) is a flow chart showing the flow of a start-up process according to an embodiment of the present invention, and FIG. 1 (b) is a flow chart showing the flow of a stop process.

FIG. 2 is a block diagram of an electronic exchange for explaining an embodiment of the present invention. Subscribers 10, 11, 12,
13 and 14 are accommodated in the digital line switches 30 and 31 via the respective line circuits 20, 21, 22, 23 and 24 having the function of breaking the loop, and the digital line switches 30 and 31 are the respective channel control circuits 40, Four
Controlled by 1. Furthermore, the speech path control circuit 40,
Reference numeral 41 is the communication path control device 6 via the time division network 50.
0, the central control device 70 can control all devices under the control of the central control device 70 via the communication path control device 60.

The operation will be described below. In the activation process, before the central control unit 70 first activates the switching operation normality monitoring function periodically, for example, the subscriber 1 in the idle state among the subscriber lines controlled by the speech path control circuit 40 is
Two lines 0, 11 are detected (step 1), and the loops of the line circuits 20 and 21 of the detected subscriber are cut off so as not to affect the subscribers 10 and 11 (step 2).

Then, the central control unit 70 notifies the communication path control circuit 40 of the housed positions and the telephone numbers assigned as the incoming line as the pseudo outgoing line and incoming line for monitoring the normality of the switching operation. , Requesting activation of exchange operation normality monitoring (step 3). A monitoring test is performed based on this request. During this period, the subscriber circuits 10 and 11 cannot use the subscriber circuits 20 and 21, but the test time is short, so that the influence on the subscribers can be avoided. After starting monitoring
It is judged whether or not to activate another speech path control circuit (step 4), and when it is activated, the process returns to step 1.

Next, when the switching operation normality monitoring is stopped, the central controller 70 requests the passage control circuit 40 to stop (step 5), and then the line circuits 20 and 21 detected as the pseudo outgoing line and the pseudo incoming line. Undo the loop,
Make it available to subscribers (step 6). Similarly, it is determined whether or not the processing is necessary for another speech path control circuit (step 7), and when it is necessary, the process returns to step 5.

In this embodiment, the case has been described in which the switching operation normality is monitored using the lines of the subscribers 10 and 11, but it is also possible to use the lines of the other subscribers 13 and 14, for example. Is.

[0012]

As described above, the present invention detects two general subscriber lines which are idle among the subscriber lines controlled by the speech path control circuit, and detects them only during the monitoring of the switching operation normality. Since the loop of the line circuit corresponding to the subscriber line is cut so as not to affect the subscriber line and the normality of the switching operation is monitored, the general subscriber line is used for the pseudo outgoing line and the pseudo incoming line. There is an effect that it can be effectively used as a line and that all subscriber line accommodation positions can be used for actual subscribers.
