BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an alarm processing method for controlling a duplicated circuit pack of an exchange system and more particularly to an alarm processing method for controlling a redundant circuit pack (PBA) mounted on a rack of an exchange system. And an alarm processing method.

Generally, the hardware circuit pack control of the TDX-10 is performed independently. One of the hardware circuit packs may be mounted according to each characteristic, and two of the hardware circuit packs may be redundant or load-shared. It can also be multiplexed into multiple chapters. In the case of the redundancy or load division, the alarm source for each hardware circuit pack is allocated independently, and the alarm processing at the upper level is managed and output as independent messages. As a result, it is difficult for the system operator and software application block to recognize the alerting of the circuit pack of the other side in the redundant circuit pack, and it is difficult to take prompt action in case of system failure. In addition, the redundant or load-divided circuit pack plays an important role in the system as compared to the unified circuit pack. For example, the Packet Bus Main Arbiter Board Assembly (PBMA), Packet Bus Local Arbiter Board Assembly (PBLA), Signal Terminal Management Logic of the TDX-10 ISDN Switch, Circuit packs such as a Signaling Terminal Management Logic Board Assembly (SMLA) and a Signaling Terminal Management Processor Board Assembly (SMPA) are each paired. If both of the circuit packs existing in the pair are abnormal, the packet call processing can not be performed or the signal processing is impossible.

Therefore, according to the present invention, not only an independent alarm of a hardware circuit pack but also an alarm management for two circuit packs can be output so that an alarm grade up and down message can be outputted. Thus, The present invention provides an alarm processing method for controlling a duplicated circuit pack of an exchange system.

According to another aspect of the present invention, there is provided an alarm processing method for controlling a duplicated circuit pack in an exchange system, the method including: an operator input step of inputting information on a circuit pack requiring duplication control, Checking whether a board failure has occurred in each of the subsystems, comparing the information with a current database (DB) information when a failure occurs, and performing a board alarm management step; Determining a rise and a release of the alarm and performing a board alarm analysis step in comparison with the state of the alarm and comparing the current alarm driving state with the previous alarm driving state to perform the alarm driving step, After updating the data of the database for alarm activation, It characterized by comprising the steps of outputting a message.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram illustrating a maintenance method in a TDX-10 Integrated Services Digital Network (ISDN) system to which the present invention is applied. Information about circuit packs that require duplication control within the switchboard should be configured with basic data. The basic data consists of three types. First, it is information on the generated circuit pack such as the subsystem number, the alarm access control assembly (AACA) number, the alarm source number, and the normal presence / absence flag. Second, there are two kinds of abnormal state of the board, which is information on the alarm number for searching for abnormal state of the same board by the board malfunction (FF: functon fail) and the board herniation (DEL: delete). This information is provided by the maintenance processor (FF) or board hernance (DEL) information if an alarm occurs due to a board failure. Third, it is an alarm number for a partner board that can perform duplication control by searching for a partner as in the case of an own alarm search. The centralized fault management block (FLM) receives, manages, and outputs alarms, faults, and status messages. The hardware alarm of the redundant board is detected by AACA, which is a firmware, to recognize the abnormal state of the actual hardware, and the maintenance consistency block (CCMI, INMP, ASMP) INMI, ASMI). The transferred information is transferred to the failure management block which is the maintenance block. The fault management block determines whether or not the detected circuit pack is redundant. If it is a redundant circuit pack to be managed, information necessary for redundancy control is extracted from a database (not shown) built in the fault management block (FLM). Based on the extracted information, duplication control is performed and the result is transmitted to a personal computer (PC) through a window control block (WM).

FIG. 2 is a flow chart for explaining an alarm processing method for controlling a duplicated circuit pack according to the present invention. For circuit packs that require duplication control, the operator performs a procedure to insert information about the circuit pack, which is necessary for redundancy control, in addition to circuit packs other than circuit packs that require duplication control in the current DB (201). When a failure occurs, it is checked whether there is a board failure for each subsystem, and board alarm management (202) is performed by comparing it with current DB information. (203), determines the necessity of driving in comparison with the current alarm drive state for the alarm drive (204), performs DB data update and drive request for alarm drive as needed, and sends a message .

FIG. 3 is a flowchart illustrating an operator input function for a duplicated circuit pack according to the present invention. When a control request for a new critical redundant board arrives from the operator (301), information on the redundant board (two boards: A and B) is inputted. A subsystem number, AACA number, and source number for a board function abnormality are inputted as a hardware alarm source of the A board (302), and the corresponding subsystem number , An AACA number, and a source number (303). The corresponding subsystem number, the AACA number, and the source number for the remaining board B are input (304), and the corresponding subsystem number, AACA number, and source number for board deletion (Delete) as the alarm source of the same board are input 305 ).

FIG. 4 is a flow chart for explaining board alarm management for a duplicated circuit pack according to the present invention. When the board alarm management is started, the maintenance processor in each subsystem operates a timer in units of 0.1 second (10 ms) (401) in order to check for hardware abnormality (401), and the AACA prepares to perform the hardware audit ). Information about the boards requiring redundancy control is sequentially accessed from the DB 403, and the AACA number and the source number, which are hardware information required for the audit, are collected and transferred to the maintenance matching block in the maintenance processor of the corresponding subsystem (404). Based on the transmitted information, the maintenance matching block performs an audit to check whether the hardware is normal or not in the corresponding AACA and receive the result (405). As a result of the audit, the AACA number, the source number, and the normal result (FailFlag) of the result of the audit are received (406) from the maintenance matching block of each subsystem, and based on this information, (407). When the information is different, the update information is updated (408). When the information is different, the update information is updated (408), and the source number of the currently updated board (409).

FIG. 5 is a flow chart for explaining board alarm analysis for a duplicated circuit pack according to the present invention. Board alarm operation is started and the board alarm operation status is updated. (When one board is abnormal status (Function Fail or Delete), the message is displayed as SINGLE BOARD DOWN. If both boards are more than DUAL BOARD DOWN (I.e., a message is output), the corresponding board alarm driving state before being reflected is reflected as an old-result (501). In order to control the duplication of the currently updated board, the currently updated board status is referred to as an SO (502). In this regard, the remaining three pieces of information are needed. That is, the source number for the counter-part function of the board to which the IO belongs (the counter part is Delete if the weak IO is the source number for the Function Fail) is extracted from the (I1) DB, 2 function error (Function Fail, Delete in relative mode) The source numbers I2 and I3 are also extracted from the DB 503. Based on the extracted source number, I1 is set as a key (504) (FailFalg search: normal value) and the value is S1 (505). Likewise, I2 is set as a key (506), and the current state of I2 is obtained from the DB (step 507). In step 508, the current state of I3 is obtained from the DB in step 509. In step 509, it is checked whether the alarm is released or not in step 510. If the alarm is canceled in step S0, 0), the alarm information of S1 is retrieved (511) and if S1 is an alarm (S1 = 1), it has no effect on the operator's message If the S1 is the alarm-canceled information, the two functions (Fail, Delete) are normal and the two functions of the other party are checked (512) because the result is NONE (513) As a result, when the AND value of S2 and S3 is an alarm occurrence, the result value is set so as to output an operator message informing that only the own board is normal (SINGLE BOARD DOWN CLEARED) with respect to the state change of S0 that has just been updated If the AND value of S2 and S3 is the alarm release, the result value is set to output a message indicating that both boards are normal (515). Now, if S0 is an alarm (S0 = 1) (S160), S1 is an alarm (S1 = 1) and it has no effect on the operator's message (NONE) (520). If S1 is the alarm-canceled information, One of the two functions (Function Fail, Delete) (517). If the AND value of S2 and S3 is alarm canceled, it is determined that only the board in question is abnormally changed with respect to the state change of the just updated S0 And the result is set to output an operator message (SINGLE BOARD DOWN) (519). If the AND of S2 and S3 is an alarm, the result is set to output a message indicating that both boards are abnormal (518).

6 is a flow chart for explaining alarm driving for a duplicated circuit pack according to the present invention. If the alarm driving procedure is started and there is no updated result message value (no change: NONE) (602) for the old result and the now-updated alarm output message class (now result) ) It is not necessary to output a new alarm activation message. If there is a change, it is not necessary to output a new alarm activation message if the previous alert message is identical to the updated alert message (603). If not, an alarm activation is required (604) and an alarm activation counter of the associated subsystem is incremented by one (605) for audible, visible alert presentation. The board-level alarm DB (information related to the generated AACA number and source number) is updated to output the alarm occurrence message list. After obtaining the class of the alarm message to be output (607), the related information is transmitted to the alarm driving processor (CCMP) (608). This message is also output to the operator through the operator terminal (609).

As described above, according to the present invention, not only an independent alarm of a hardware circuit pack but also alarm management for two circuit packs can be output to output a class up / down message, so that a user can quickly take measures There is an excellent effect.
