Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a system for monitoring signals transmitted and received by line equipment (trunk) and signal transmission and reception equipment (sender, register) in a telephone exchange.

[Background of the invention]

Conventionally, the most common and effective procedure for searching for a failure when a call becomes impossible due to a line failure with another station or a failure in the line equipment is to make a determination based on the history of signals sent and received by the line equipment. be.

However, there is no effective means for recording the history of signals sent and received by the line equipment, and a great deal of time and effort is wasted in searching for faults in many cases, relying on external measuring devices such as electromagnetic oscilloscopes.

[Purpose of the invention]

An object of the present invention is to automatically record and display the signals sent and received by the line equipment and the signal transmitting/receiving device as a procedure for troubleshooting, thereby minimizing the number of man-hours spent on troubleshooting and maintaining stable telephone exchange services. There is a particular thing.

[Summary of the invention]

Therefore, in the present invention, any line device (trunk) or signal transmitting/receiving device (register, sender)
can be registered as a monitoring target, record all history of signals sent and received by the registered line device or signal transmitting/receiving device, and display the recorded signal history information (monitoring information) on a display device. This has the advantage that in the case of a failure, line operation, signal transmitting/receiving device failure, etc., it becomes very easy to search for the failure.

[Embodiments of the invention]

Next, one embodiment of the invention will be described based on the drawings.

The figure is a relay system diagram of an embodiment of the signal monitoring system according to the present invention. Here 2 is the call path switch SW
1 is the incoming trunk IC, 3 is the outgoing trunk OGT, 4 is the incoming register IR, 5 is the outgoing sender OS, 6 is the trunk controller TC, 7 is the trunk scanner TSCN, 8
is the signal distribution device SD, 9 is the central control device CC, 10
is the main memory device MM, 11 is the input/output control device IOC,
12 is a typewriter TTY.

First, a case will be described in which a maintenance person registers the incoming trunk 1 shown in FIG. 1 as a signal audit target. The audit registration request is made by inputting the registration request and the number of the incoming trunk 1 from the TTY 12, and this information is recorded in the audit trunk number storage area (not shown) of the MM 10 via the IOC 11-CC9.
Here, when the incoming trunk 1 is activated, the activation signal is
Displayed on TSCN7 and read with CC. As is well known, when the exchange processing program detects the activation of the incoming trunk, it selects and captures the empty register 4 and establishes a communication path between the trunk 1 and the incoming register 4. At this time, the exchange processing program detects the activation of the incoming trunk. Check whether the registration has been audited or not with the contents of the audit trunk number storage area (not shown) of the MM10, and if it matches the trunk number to be audited, send the captured incoming register number to the audit register number storage area (not shown) of the MM10. Record. After that, when the selected number signal is received by the input register, the selected number signal is displayed on the TSCN 7 and read by the CC 9, as is well known. When the exchange processing program detects the selected numeric signal, it records the numeric information in a predetermined area of the MM 10, but at the same time checks whether the input register 4 is registered for audit or not in the audit register number storage area of the MM 10 (not shown). If it matches the register number to be audited, the received numeric signal is recorded in the audit information storage area (not shown) of the MM 10. In this way, each time the input register 4 receives a selected number signal, it checks whether it is at the auditing level, and
If an audit is in progress, it is recorded in the audit information storage area (not shown) of the MM 10. The above is an example in which the incoming trunk is registered as an audit target, but it goes without saying that the selected numerical information can be audited in the same way for the outgoing trunk as well. Additionally, if an incoming register or an outgoing sender is registered as an audit target, the above-mentioned recording and verification of the trunk number in the audit trunk number storage area can be omitted, and signal auditing can be performed in the same way as in the case of trunks. Needless to say. In addition, the recorded audit information is sent to MM1 by a read request from TTY12.

2 will be displayed on top.

〔Effect of the invention〕

As explained above, in the present invention, any line operation (trunk) or signal transmitting/receiving device (register, sender) can be registered as an audit target, and the signals transmitted and received by the device can be automatically registered without adding an external measuring device. Information history can be recorded and displayed, so if a signal transmission/reception problem occurs with another station, the efficiency of troubleshooting can be greatly improved by registering the line equipment or signal transmission/reception equipment connected to the faulty line for auditing. It is possible to maintain a stable exchange service.
