OUTPUT DATA PROCESSOR FOR BASE STATION MODEM FOR IS-2000 MOBILE COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an output data processor of a base station modem for an IS-2000 mobile communication system capable of preventing the deterioration of the quality of speech. SOLUTION: The output data processor is provided with a series/parallel converting part 21 for converting serial data inputted from a base station modem for an IS-2000 mobile communication system into parallel data, a parity inspecting part 22 for inspecting a parity from parallel data converted by the series/parallel converting part, a state processing part 23 for generating interruption according to the parity state inspected by the parity inspecting part, and for holding the state until a clear signal is inputted from a CPU, and an output controlling part 25 for confirming the parity state inspected by the parity inspecting part, and for outputting a low signal when any error is generated, and for outputting the parallel data converted by the series/parallel converting part when any error is not generated. Thus, it is possible to prevent the transmission of data whose error is generated from the base station modem, and to prevent the deterioration of the quality of speech.
