METHOD FOR CHECKING SYSTEM CLOCK FOR BASE STATION STABILIZATION

摘要

PURPOSE: A method for checking the system clock for base station stabilization is provided to prevent a problem caused by the unlimited reset in the event of the loss of a system clock supplied to a channel card required for the CDMA(Code Division Multiple Access) PCS(Personal Communication Service) system. CONSTITUTION: A system clock is supplied to a channel card from a clock supplier(S10). The system clock supplied is checked independently in a logic processer of the channel card, and reported to a upper level digital signal processor(S40). In case that the loss of the system clock is caused(S30), the channel requests the reset of an associated board to the upper level control digital signal processor(S50).
