Abstract: PURPOSE: A method for monitoring and controlling performance of a synchronous physical layer applied in an access network is provided to supply platform configuration that is a guiding principle in implement of performance monitoring device of synchronous physical layer. CONSTITUTION: Performance data of a performance monitoring device are initialized(S111). If installation of a board is detected(S112), an error accumulative value on signal is obtained by collecting performance data through performance accumulative registers of a physical layer chip every second(S113). If new board being installed is not detected any longer(S114), the first board is set(S121). If the first board exists, performance data processing is performed by obtaining other performance elements through the error accumulative value obtained(S124). A UAS(UnAvailable Second) is decided by using the performance elements obtained from the performance data processing(S125). A critical value every 15 seconds and a day is stored. If a value of performance elements accumulated in 15 second and a day is decided to over corresponding critical value, signal is decided to be a performance drop state(S127) and the performance elements accumulated in every 15 seconds and a day is reported to a network management device periodically(S128).

Abstract: PURPOSE: A method for processing a poll fail of a PP(Peripheral) board in a keyphone system is provided to regard what poll data is not transmitted as a poll fail by the PP board. CONSTITUTION: A CPU of a PP(Peripheral) card waits poll data at a determined interval. If the poll data is not transmitted, the CPU runs a timer, and decides whether a state is a poll data time out(ST11-ST13). If so, the CPU regards the state as a poll fail, and displays a poll fail state(ST14). After generating an interrupt to the CPU of an MPB(Main Process Board), the CPU decides whether the poll data exists(ST15). If so, the CPU clears a display state, and preserves the poll fail state as statistic data to perform a statistic process. The CPU performs a self test to check a component element within a board(ST16).
