The present invention relates to a distributed private exchange system, and more particularly, to a debugging apparatus and a method of a distributed private exchange system to improve the debugging performance of the distributed private exchange system.

In general, a large-capacity private switching system constituting a voice communication network is configured as a distributed system to provide voice communication services to a large number of subscribers. In other words, a large-capacity private exchange system is composed of multiple nodes (central exchange and at least one local exchange). Processors in charge of one node are distributed separately and distributed processors use a global bus to each other. It is designed to send and receive messages. In addition, the method generally used for debugging the operations of distributed processors provides a service for analyzing through a serial output device in combination with debugging output by assigning a debugging message output identifier for each specific function.

1 is a view showing the configuration of a distributed private exchange system in the prior art.

As shown in FIG. 1, the conventional private switching system (PDU) has a central processor (Central Switching System) 10 for managing programs and data for providing a voice communication service requested from a terminal device connected to a voice communication network, and for each node. Inquiry and change configuration information and subscriber data of the local processor (local exchange) 20 that provides voice communication service, the exchange processor (message exchange) 30 that exchanges messages between them, and the private exchange system, and the fault information. It is composed of a maintenance computer (maintenance device) 40 that shows and outputs a debugging message.

The central processor 10 may include a global message management unit 11 that processes a global bus message, a hard disk storage device configured to provide distributed node configuration information, an operating program, and subscriber information and maintenance data for providing a voice communication service. The storage device management unit 12 managed by the server, the maintenance unit 13 monitoring the normal operation of each node and reporting the operation status of the switching system to the maintenance computer, and the debugging message outputting debugging messages to the serial output device. It consists of an output 14.

The local processor (local exchange) 20 collects central information by collecting the voice message processing unit 22 and the maintenance information for providing voice communication services of the distributed nodes and the global message management unit 21, which also processes the global bus messages. The maintenance management unit 23 reports to the processor 10, and the debugging message output unit 24 for outputting a debugging message transmitted from the voice service processing unit and the maintenance management unit 23 to the serial output device.

The exchange processor 30 is composed of a message exchange unit 31 for exchanging messages between the central processor and local processors.

The maintenance computer 40 maintains and receives maintenance information from the central processor 10, and provides a maintenance management unit 41 and a central office that provide input / output windows for operating configuration information and subscriber data. It consists of a serial input and output management unit 42 for transmitting and receiving the debugging message output from the processor and the local processor through the serial line (1).

In the distributed private exchange system of the related art configured as described above, the operation of outputting a debugging message for monitoring the operating state of the system is as follows.

In order to output the debugging message, the maintenance manager connects the central processor 10 or the local processor 20 to be monitored with the maintenance computer 40 and the serial line 1 composed of serial input / output cables. Then, the serial input / output management unit 42 of the maintenance computer 40 inputs a debugging message identifier for classifying debugging message types to be monitored and sets whether or not to output the same.

In the case of the central processor 10, a debugging message is monitored by the maintenance unit 13 that monitors the normal operation of individual nodes (local processors 20) and reports the operation state of the private exchange system to the maintenance computer 400. It passes to the debugging message output unit 14 for outputting to the serial output device. The debugging message transmitted to the debugging message output unit 14 determines whether to output the output by comparing with the debugging message output identifier and the debugging message output identifier. The message allowed to be output is transmitted through the serial input / output serial line 1 connected to the maintenance computer 40 and output through the serial input / output management unit 42 of the maintenance computer 40.

In the case of the local processor 20, the voice message processing unit 22 providing voice communication service and the maintenance management unit 23 collecting and reporting maintenance information to the central processor 10 transmit the debugging message to the serial output device. Delivers to the debugging message output unit 24 to output. The debugging message transmitted to the debugging message output unit 24 may be compared with the debugging message output identifier and the debugging message output identifier to determine whether to output the debugging message. The message allowed to be output is transmitted through the serial input / output serial line 1 connected to the maintenance computer 40 and output through the serial input / output management unit 42 of the maintenance computer 40.

In order to prevent the debugging message from being output, the maintenance manager outputs the serial I / O of the maintenance computer 40 while the central processor 10 or the local processor 20 being monitored is connected to the maintenance computer 40 by a serial input / output cable. Input to release whether or not to output the debugging message output identifier monitored by the management unit 42.

(S40).

FIG. 4 is a subroutine diagram illustrating a detailed process of a debugging message registration process in the process of FIG. 3.

First, when the monitoring target is the central processor 100, in order to output a debugging message, a command for registering the output identifier of the debugging message to be monitored through the maintenance command input / output unit 410 of the maintenance computer 400 is input (debugging). Message input process) (S11).

The maintenance computer 400 transmits the monitoring setting command message to the maintenance management unit 130 of the central processor 100 (debugging message transmission process) (S12).

The above-described debugging message registration process performs different processing depending on the case where the monitoring target is the central processor 100 and the local processor 200. Therefore, the central processor 100 determines whether the monitoring target is the central processor 100 or the local processor 200 (monitoring determination process) (S13).

As a result of the determination in S13, when the monitoring target is the central processor 100, the maintenance manager 130 registers an option of outputting the debugging message of the debugging message manager 140 of the central processor 100 and the type of debugging message to be output ( Central debugging message registration process) (S14).

The output allowed debugging message is transmitted to the storage device management unit 120 that manages the hard disk storage device of the central processor 100 to be recorded (S24). (S21 and S24: central debugging message storage process)

Next, in the case where the target for monitoring the debugging message is the local processor 200, the voice service processor 220 that provides a voice communication service and the maintenance manager 230 that collects and reports maintenance information to the central processor may be generated. Delivering the debugging message to the debugging message management unit 240 (S22). The debugging message transmitted to the debugging message management unit 240 determines whether to output the output by comparing the debugging message output identifiers currently set in the local processor and the debugging message output identifiers. The debugging message allowed to be output is converted into a global bus message format used between the central processor and the local processor and passed to the global message processing unit 210. The global message processing unit 210 of the local processor 200 transmits the debugging message allowed to be output through the exchange processor 300 to the central processor 100 (local global message transmission process) (S23).

The global message processing unit 110 of the central processor 100 that receives the debugging message allowing the output transmitted from the global message processing unit 210 of the local processor 200 is a storage device such as a hard disk of the central processor 100 ( The storage device) transmits the debugging message to the storage device management unit 120, and the storage device management unit 120 stores the received debugging message in the storage device (storage unit) (central debugging message storage process) (S24).

When the number of steps S21 to S24 described above is performed, the process returns to the above-described process of FIG. 3 to perform the process S30.

FIG. 6 is a subroutine diagram illustrating a detailed processing of the debugging message output releasing process of S40 of FIG. 3.

In order to not output the debugging message while outputting the debugging message from the maintenance computer 400 by the above-described process of FIGS. 3 to 5, monitoring is performed through the maintenance command input / output unit 410 of the maintenance computer 400. A command for releasing the output of the debugging message is input (monitor release command input process) (S41).

The maintenance computer transmits a monitoring cancel command message to the maintenance management unit 130 of the central processor 100. The maintenance management unit 130 of the central processor 100 initializes a message output option of the debugging message management unit 140 of the central processor 100 when the location to cancel monitoring is a central processor, and sets the type of debugging messages to be output. Delete (central monitoring release process) (S42).

In contrast, when the location to be monitored is the local processor 200, the maintenance manager 130 of the central processor 100 transmits a monitoring cancel command message to the maintenance manager 230 of the local processor 200 (local monitoring Release command transmission) (S43).

The maintenance management unit 230 of the local processor 200 initializes the message output option of the debugging message management unit 140 and deletes the debugging message type to be output (local monitoring release process) (S44).

As described above, in the present invention, the distributed private switching system outputs a debugging message from a serial input / output method to a network input / output method using a global bus message so that multiple central and local processors can be simultaneously monitored.
