Hereinafter, the present invention will be described in detail with reference to FIGS. 1 to 4.

The exchange system loads initial data into the access switch processors of each access subsystem in step 400. The exchange system generates a main process when the data load of step 400 is completed. When the main process is created, the main process creates a subprocess of the main process in step 404. A subprocess generated in the subprocess of the main process is shown in Table 1 below.

PROCESS NAME TYPE STACK TDMH_Main Control 8 K TDMH_MmcCntl child 8 K TDMH_DisStsInf child 8 K TDMH_Trk105Tst Child 4 K TDMH_RasmCntl Control 8 K TDMH_Audit Child 4 K TDMH_PhmStsChk Child 4 K TDMH_StsChk Child 4 k TDMH_BERSup Child 4 K

Each of the sub-processes of Table 1 will be described below.

The TDMH_Main process checks the current state, and after interworking with other blocks associated with the maintenance function, receives and reports the necessary items for state management from the child process or related blocks that performed the corresponding work. Send the results to the EC and end the task. In addition, the TDMH_MmcCntl generates a process for performing a corresponding function such as blocking and recovery status output by the operator by receiving a signal from the MIT that requires a function performed by an operator in the TDMH block, and a signal requiring performing another function. Wait for the reception to receive. Next, the TDMH_TstRslt process receives a result of a test from a block such as TCDT, AST, DTT, TLT, DST, etc., which is a block for performing a test result of the monetary system, and operates a message changed according to the result of the received test. If it is an automatic test, the test result when the test result is abnormally processed is also output to the operator of the maintenance unit 160.

The TDMH_Trk105Tst process, which is a relay line-related process among the lower processors generated by the main process, is a function to perform preparation during a relay line test. In the requested block, send a signal according to test completion. Therefore, the state of the relay line is shifted to the state under test, and if the relay line is in use, the relay line test preparation result is output according to the use of the relay line. In addition, the TDMH_RasmCntl process is a state control between the remote access switching module when the access subsystem of the switching system is operating as a remote access switching module (RASM), that is, the connection state management of the PCM link and remote access Receives the signal that performs the switching module's synchronizer and generates the process or directly performs the state management.

In addition, the TDMH_Audit process anticipates a case where the state of the call path equipment of the switching system is inconsistent, and finds and recovers a current hardware state and a software state that are inconsistent. In particular, in the case of a relay line, there are many states. When comparing the state of the current lower level processor with the state of the main processor, the state is inconsistent and monitoring is always performed to reduce the failure of the call or the loss of call processing resources. The TDMH_Audit process may be executed in the unit of a card in which the equipment is mounted in performing the inspection, and the state of each of the relay lines may be checked, and the relay line may be checked in units of links. In addition, the check time is executed in each set period, and the information of the period processes change, prohibition and suspension at the request of the operator.

The TDMH_StsChk process performs an answer-back on the packet link device periodically to perform an inspection, and performs a function of isolation and recovery for a link in which a failure occurs during the inspection. Next, the TDMH_stsChk process obtains statistical data by sampling the state of the equipment at predetermined intervals in order to obtain the average isolation rate for each failure cause of the equipment. Finally, the TDMH_BERSup processor collects bit errors occurring on the link to measure the transmission quality of the digital trunk line of the switching system, analyzes the collected bit errors, and analyzes the result and quality according to the operator's request. Outputs the result of the faulty relay line.

On the other hand, when the generation of the above-described subprocesses is terminated in step 404, the process proceeds to step 406 and the generated subprocessors perform the above-described operations, respectively. When the above-described operations are performed, predetermined processes generate child processes required during execution. do. Among the lower processes shown in Table 1, there are the TDMH_Main process, the TDMH_MmcCntl process, and the TDMH_RasmMmcBlk process.

First, the process generated by the TDMH_Main process is shown in Table 2 below.

PROCESS NAME TYPE STACK TDMH_sup_call_cntl Child 4 K TDMH_sup_call_flt Child 4 K

The operation of the process of Table 2 will be described below. First, the TDMH_sup_call_cntl process performs a monitoring result for equipment occupancy interruption and equipment quality of the switching system at the request of an operator, and changes the threshold value according to the mounting and isolation state of the equipment. In addition, unlike the TDMH_sup_call_cntl process, the TDMH_sup_call_cntl process monitors the equipment occupancy disturbance and the equipment quality regardless of an operator's request, and automatically isolates it when a continuous interruption occurs. In addition, the equipment occupancy disturbance monitoring results and quality inspection results are output to the maintenance unit 160 on a daily basis and reported to the operator.

A process generated by the TDMH_MmcCntl process is shown in Table 3 below.

PROCESS NAME TYPE STACK TDMH_mmcBlk Child 8 k TDMH_mmcUblk Child 8 K TDMH_DisStsInf Child 12 K TDMH_StsModChg Child 4 K

Looking at the operation of each process of Table 3 as follows. First, the TDMH_mmcBlk process receives a signal for performing the chaining of the corresponding equipment by a command received from the MMP 34 of the maintenance unit 160 by a command inputted by the operator to perform the closing of the telephone line system. The process is generated by a TDMH_mmcCntl process which receives a call path equipment closure why signal from the MIT via the EC and then controls the command received from the MMP 34 by an operator request. It is created during the execution of the process. The execution of the process analyzes the parameters of the command received from the operator, requests the MMC Block of the corresponding device to the TDSL block, and updates the database. Therefore, when the number of blocks mounted in the corresponding equipment exceeds the threshold, a signal for requesting a threshold alarm is transmitted to the FLM block, and the output result of the block is output to the operator.

Next, the TDMH_mmcUblk process receives a signal requesting the recovery of the corresponding device at the request of the operator and performs recovery of the call path equipment. The process receives the signal of the call path equipment recovery from the EC 301 and from the MIT 302 to be generated by the TDMH_MmcCntL. The execution of the process analyzes the parameters of the inputted operator's command and obtains the number of unserviced calls when the number of equipments in the unserviceable state due to the TDSL 303 block decreases to less than the service limit due to MMC Unblock. , Compare with limit alarm clear output condition. The result of the comparison is transmitted to the FLM 305 block, and the result of the transmission is output to the operator. In addition, the TDMH_DisStsInf processor is a process for outputting the call path equipment status at the request of an operator and outputs the status of the equipment according to the status of the equipment. At this time, the status of the output equipment determines the priority for each grade and outputs.

Finally, the TDMH_StsModChg process performs a corresponding process when a change request of Active / Stand By of the TSL or the like or a function change request of a signal device is performed, and informs an operator of the result or changed state.

On the other hand, the child process generated by the TDMH_RasmMmcBlk process is shown in Table 4 below.

PROCESS NAME TYPE STACK TDMH_RasmMmcBlk Child 4 K TDMH_RasmMmcBlk Child 4 K

The child process shown in Table 4 is described below. First, when the TDMH_RasmMmcBlk process is operating as a remote access switching module of the corresponding access subsystem, the TDMH_RasmMmcBlk process performs a function of enabling and disabling the state management of the PCM link between the main body and the remote access switching module. Next, the TDMH_RasmMmcBlk process outputs an MCM block / unblock, a network synchronization state output for managing the state of the network synchronizer used by the remote access switching module when the access subsystem of the switching system is operating as a remote access switching module. It performs the function of changing the synchronizer state.

Therefore, in step 406, the sub-process checks the operation state of the exchange system, and if necessary, generates the above-described child process, and if the required process is generated, proceeds to step 408 and the processes perform the above-described operation. .

As described above, by performing the state management and maintenance of the call routing equipment in the exchange system in the corresponding process, the PS exchange forms a more perfect call in performing the call of the PS terminal, and improves the call quality. There is an advantage to this.
