Patent ID: 7002954

Claim:
A method for processing a large amount of intra-calls in a remote control system of a full electronic exchange system having a time switch block with a voice memory device and a control memory device having an input and output data regions to switch the Pulse Code Modulation (PCM) data to an intra-direction, and a call pass controller for transferring said PCM data to a host system and for looping said PCM data to said intra-direction, comprising the steps of: writing call direction data for designating an intra-call direction into the respective said input and output data regions of said control memory device at a designated memory and address to switch said PCM data sequentially stored in said voice memory device to said intra-direction; and, looping entire channels to said intra-direction to switch said PCM data from said time switch block to said intra-direction if said call direction data designates said intra-call direction based on the amount of said intra-calls.
