Abstract:
(1) OMP(Operation and Maintenance Processor)'s sending a state test requesting message to a selected processor, operating a related timer, and testing the state of the processor; (2) when the processor is in normal state, sending a state test ending message to the OMP (1) to stop the timer, and sending a state test requesting message to the next processor to operate the related timer; (3) when the processor is in abnormal state, sending information indicating that the processor is abnormal to the OMP (1), and OMP's sending a processor audit message; (4) sending a message requesting for the state test of the next processor to operate the timer; and (5) repeating the procedures up to the last processor.
Abstract:
(1) determining whether error information received from a specific processor is detected from a software block or a hardware block; (2) checking whether the information is a defined event alarm report when it is detected from the hardware block; (3) increasing the number of events when it is the defined event, outputting an event of a predetermined grade, and ending; (4) determining whether an accumulated number of errors exceeds a threshold value when it is not the defined event; (5) outputting an error message when the number of errors is below the threshold value; and (6) determining the error grade and ending.
Abstract:
the first step (21 or 23) of loading one by one and examining whether other demand for loading is asked; the second step (24,28,25) of examining whether the total counter of the loading process exceeds the threshold value and increasing a counter; the third step (26 or 28) of stopping the one by one loading and stopping the broadcasting loading after operating it when the counter exceeds the threshold value, otherwise, stopping the one by one loading after operating it.

Abstract:
The electronic switching system comprises an INP (Interconnection Network Processor); a NTP (Number Translation Processor); an ASP (Access Switching Processor); an OMP (Operation and Maintenance Processor); a SSP (Space Stitch Processor); a TSP (Tine Process Processor); a LSP (Local Service Processor); a GSP (Global Service Processor); an ASIP (Analog Trunk Interface Processor); an ATIP (Analog Trunk Interface Processor); a DTIP (Digital T1 Trunk Interface Processor); a DCIP (Digital CEPT1 Trunk Interface Processor). The control method preventing the system malfunction caused by the overload calls has the step for detecting the overload call condition with the subscriber switching system processor; step for deciding the priorities of the calls; and step for holding the low priority calls according the degree of the overload condition.
Abstract:
The method that translates the number for special services is provided. The subsystem of the exchanger consists of an ASS(Access Switching Subsystem), an INS(Interconnection Network Subsystem) and a CCS(Central Control Subsystem). The ASS(1) includes a LTAS that controls the interface between subscriber and trunk, a LSS that controls time-division switch, a SSS that generates the alarms such as R2 MFC signal and DTMF transmitting/receiving signal, and an OSS that controls the various kinds of special services.
Abstract:
The system improves the special number (SN) service of the switching system. The method sends the call to the receiver located in the closest place to the sender and supports the method grouping sending locations of SN in order to assign a receiver. This method does not restrict the length and scheme of SN. This system is composed of an access switching subsystem (ASS), an inter-connect network subsystem (INS) and a central switching subsystem (CCS).
