Abstract

PURPOSE:To simplify a system by connecting a maintenance board to a channel system connecting part of a main controller and monitoring and testing the system through the channel system connecting part of the main controller from the maintenance board. CONSTITUTION:The monitor indication from a maintenance board STC is transmitted to a management processor MPR through a maintenance board interface circuit CI and a pseudo network PNW. The management processor MPR transmits this monitor indication and required control information to a required call processor CPR through a channel coupling device CCA and requests transmitting-back of monitor information. The call processor CPR gathers monitor information of its own device and a corresponding channel device on a basis of received monitor indication and control information and transmits back these information to the management processor MPR through the channel coupling device CCA. The management processor MPR adds required control information to transmitted-back monitor information and transmits them to the maintenance board STC through the pseudo network PNW and the maintenance board interface circuit Ci. As the result, the maintenance board STC can monitor operation states of the call processor and the channel system device corresponding to the monitor indication.

[Problem that the invention seeks to solve]

As is clear from the above description, in conventional system monitoring test methods, the maintenance stand transmits and receives monitoring test information to and from each call processor. As a result, there is a problem in that as call processors and communication path devices are added, the connection devices and connection paths must be expanded. Furthermore, each call processor must send and receive various control information to and from the management processor each time it receives a monitoring test instruction from the maintenance stand, which poses the problem of complicating control for monitoring tests.

[Means for solving problems]

The present invention provides a multifunction device that includes one main control device that manages and controls the entire system, a plurality of call processing control devices that control corresponding communication path devices, and a maintenance stand that performs system monitoring tests. In the processor-type electronic switching system, the maintenance stand is connected to the communication path system connection section of the main control device, and a monitoring test of the system is performed from the maintenance stand via the communication path system connection section of the main control device. By doing so, the above problem is solved.

[Effect]

That is, according to the present invention, the maintenance stand is connected to only one main control device, and even when call processing control devices and communication path devices are added, the connection devices and connection paths can be expanded. This is not necessary, and the monitoring test control of each call processing control device and communication path system device is also consolidated into the main control device, which simplifies the process.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram illustrating a system monitoring test method according to an embodiment of the present invention. Note that the same reference numerals refer to the same objects throughout the plan. In FIG. 1, a pseudo network PNW, which is a smaller-scaled general network NW, is connected to the communication path bus SB of the management processor MPH, which was not used in FIG. A maintenance stand interface circuit CI connected to the maintenance stand STC is accommodated.

In FIG. 1, a monitoring instruction from the maintenance console STC is transmitted to the management processor MPH via the maintenance console interface CI and the pseudo network PNW.
The PR transmits the monitoring instruction and necessary control information to the required call processor CPH via the channel coupling device OCA, and requests return of the monitoring information. The call processor CPR based on the received monitoring instructions and control information.

Monitoring information of the own device and the corresponding communication path system is collected and sent back to the management processor MPR via the channel coupling device CCA. Management Processor MPR
adds necessary control information to the returned monitoring information and transmits it to the maintenance stand STC via the pseudo network PNW and the maintenance stand interface circuit CI. As a result, the maintenance stand STC is able to monitor the operational status of the call processor CPR and communication path equipment corresponding to the monitoring instruction. In addition, in order to confirm the normality of the signal tone receiving circuit RC■ accommodated in each network NW, the signal tone receiving circuit RCV and the signal tone generating circuit TNG are connected via each network NW, and the signal tone generating circuit Also when testing the signal tone receiving circuit RCV from the PB double signal generated from TN9, the maintenance stand STC sends the required signal tone to the management processors MP and H via the maintenance stand interface circuit CI and the pseudo network PNW. Transmit test instructions for the receiving circuit RCV. The management processor MPR, which has received the test instruction, transmits the test instruction and required control information to the required call processor CPR via the channel coupling device OCA.

Based on the received test instructions and control information, the call terocessor CPR connects the signal tone receiving circuit RCV and the signal tone generating circuit TNG via the network NW, and generates a signal from the PB double signal generated from the signal tone generating circuit TNG. The sound receiving circuit RCV is tested and test information indicating the test result is sent to the management processor M via the channel coupling device CCA.
Return it to PH. The management processor MPR adds necessary control information to the returned test information and sends it back to the maintenance stand STC via the pseudo network PNW and the maintenance stand interface circuit CI. As described above, the maintenance stand STC confirms the normality of the signal tone receiving circuit Rc■ in response to the test instruction sent out earlier. Note that when the maintenance stand STC performs an outgoing connection test and an incoming connection test using the outgoing telephone circuit OTL and the incoming telephone circuit TTi accommodated in the network NW', the call processor CPR and the management processor MPR Sends and receives various control information.

As is clear from the above description, according to this embodiment, the maintenance stand STC connects the maintenance stand interface circuit CI accommodated in the pseudo network PNW connected to the communication path bus SH of one management processor MPH. This makes it possible to monitor the operating status of all call processor CPRs and corresponding communication path devices, and even if call processor CPRs and corresponding communication path devices are added, connection devices and connection paths can be monitored. There is no need to expand . Also, since monitoring test instructions for each call processor CPH and monitoring test information from call processor CPR always go through management processor MPR,
Controls for monitoring tests are also simplified.

Note that FIG. 1 is only one embodiment of the present invention, and for example, the trunks accommodated in each network NW are not limited to the signal tone generating circuit TNG and the signal tone receiving circuit RCV, and may include many others. However, the effects of the present invention do not change in any case. In addition, the network N connected to the communication path bus SB of each call processor CPH
The number of Ws is not limited to one, and a plurality of Ws may be connected; however, the effects of the present invention remain the same even in such a case. Furthermore, the connection format between the management processor MPR and each call processor CPR is not limited to the one shown in the diagram, and many other modifications may be considered, but the effects of the present invention will not change in any case. . Furthermore, it goes without saying that the type of test instruction is not limited to those related to confirming the normality of the signal tone receiving circuit RCV.
