Abstract

PURPOSE:To reduce the load of the processor, by installing the control memory in correspondence to the memory switch to store the counter monitoring the time, the type of signal and the mode each and then transmitting the signal through an automatic switching of the switch in a fixed cycle. CONSTITUTION:The input signal of the incoming common line Hi is written periodically into the address of the channel memory SPM which is designated by the writing address counter WAC. And in the case of reading, the address is designated based on the channel number of the line Hi which is written into the switch memory SWM, and the contents of the memory SPM is sent out to the outgoing common line Ho. The address of the memory SWM is designated by the reading address counter RAC synchronizing with the output signal. And the contents of the control memory CM is read in synchronization with the memory SWM. The memory CM stores the channel number corresponding to the type of the signal being sent to the line Hi and in accordance with the number of the line Ho. And this correspondence of the numbers is controlled by the selection circuit SEL2 in order to follow either one of the memories SWM and CM.
