Abstract

PURPOSE:To test continuity under software control without providing an unnecessary testing device, by providing a connecting means of sending the contents of the specific output time slot of a switching network back to the input time slot that corresponds to this output time slot. CONSTITUTION:Under a command from a central processor, test data T is written in address (a) of signal transmitting memory 22. Control memory 24 stores this test data in time slot (i) at the input part of data extraction device C, which extracts and transfers only this data to data transfer device D via return channel 34. Then, data T inserted into time slot (i) is written by control memory 16 in primary channel memory 12, transferred to secondary channel memory 20' and further to the 2nd input time slot, and written in signal receiving memory 14', where it is compared with the contents of signal transmitting memory 22 to check the continuity state.
