METHOD AND CIRCUIT FOR PROCESSING CALL OF TIME SWITCH IN EXCHANGER

摘要

PURPOSE: A method and a circuit for processing a call of a time switch in an exchanger are provided to enable various system shapes by realizing time switch pool structure. CONSTITUTION: A peripheral process interface part(209) inputs and outputs switching data and maintenance data from an upper processor managing a time switch. A clock interface part(211) regenerates and distributes clocks for realizing a pool type time switch. A control memory part(201) receives the clocks from the clock interface part(211) for reading and writhing control data through the peripheral process interface part(209) and performs a switching command by an upper software. An input part(205) receives the clocks, and transmits input serial data converted to fit for time switching. A speech memory(203) receives the output of the clock interface part(211) and successively writes PCM data input from the input part. An output part(207) outputs PCM data switched from the speech memory(203).
