Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic exchange, and in particular, monitors a connection sequence indicating a flow of signals transmitted and received on a subscriber line and a trunk line during call connection processing in the electronic exchange. It is related to the method.

[Conventional technology]

Generally, an electronic exchange has one bus 10 as shown in FIG.
Is connected to a central processing unit 3 having a call processing program 8 and a speech path controller 4, and the speech path controller 4
An exchange switch 5 for introducing a plurality of subscriber lines 6 and a trunk line 7 is connected, and a call processing program 8 operating on the central processing unit 3 executes control relating to call connection processing.

In the conventional electronic exchange of this type, as shown in FIG. 2, the maintenance operation terminal 1 capable of displaying alphanumeric data.
Is connected to the bus 10, and the subscriber line 6 or the trunk line 7 is designated from this maintenance and operation terminal 1 and a predetermined command is input to the central processing unit 3, so that the designated line at that time The state of the call connection process (for example, the state of receiving dialed digits, calling of the other party, busy state, etc.) can be displayed on the maintenance operation terminal 1.

[Problems to be solved by the invention]

As described above, conventionally, the state of the subscriber line 6 or the trunk line 7 at a certain time point can be monitored, but the connection sequence is monitored by paying attention to the certain subscriber line 6 or the trunk line 7. I couldn't do that.
That is, generally in an electronic exchange, a call processing program 8 operating on the central processing unit 3 controls the call connection processing, monitors the state of the subscriber line 6 or the trunk line 7, and changes the line. When a signal from the subscriber or the other party's exchange is input, the next action to be taken in response to the change is analyzed and determined, and a necessary control signal is sent to the line to make a series of calls. It controls the connection process. The flow of signals transmitted and received through the subscriber line 6 or the trunk line 7 in the process of such call connection processing is called a connection sequence, but conventionally, this connection sequence could not be monitored in real time.

When the connection sequence is normal, for example, the call signal → dial tone signal → numeric signal → callee call signal → call → caller disconnect signal → callee call end If there is a failure in itself, or if there is a failure in the terminal side or the partner exchange connected by the line, the connection sequence will be different from the normal case. Therefore, in order to select the faulty line and confirm the restoration status, it is desirable to focus on one subscriber line 6 or trunk line 7 and to be able to monitor the connection sequence on that line. To be done.

Therefore, an object of the present invention is to focus on an arbitrary subscriber line or trunk line and enable a connection sequence showing the flow of signals transmitted and received on the line to be monitored on a maintenance operation terminal in real time. .

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention uses one bus,

If a change in the line is detected while the call is being processed, call processing is performed for the change, and connection sequence update data indicating a signal received from the line and transmitted to the line during the call connection control is created. Program and update for sending connection sequence update data created by the call processing program to the maintenance operation terminal controller A chromatography data transmission program, the operation and maintenance terminal control apparatus, based on the connection sequence update data received from the update data transmission program,
Create display data for displaying a connection sequence showing a flow of signals transmitted and received for call connection processing on the designated subscriber line or trunk line, and display it on the maintenance operation terminal in real time. I have to.

[Action]

According to the present invention, when a maintenance worker or the like designates a subscriber line or a trunk line from the maintenance operation terminal, the call processing program provided on the central processing unit causes the maintenance operation terminal controller to designate a subscription designated by the maintenance operation terminal. When a change in the line is detected while monitoring the status of the operator's line or trunk line, the call connection control for the change is executed and the signal received from the line and transmitted to the line during the call connection control. Is created, and the update data transmitting program sends the created connection sequence update data to the maintenance operation terminal control device. And the maintenance operation terminal control device
