ABSTRACT:
A method for processing a great amount of intra-calls in the remote control system of a full electronic exchange system, whose time switch block is provided with a voice memory device and a control memory device to switch the PCM data to the intra-direction, and with a call pass controller to transfer to the host system or loop to the intra-direction the PCM data, comprises the steps of writing call direction data for designating the intra-call direction into the data region of the control memory device to switch the PCM data sequentially stored in the voice memory device to the intra-direction, and looping the entire channels to the intra-direction to switch the PCM data from the time switch block to the intra-direction if the call direction data designates the intra-call direction according to the treatment of the great amount of the intra-calls.
