Abstract
PURPOSE:To make it possible to prevent malfunction due to a selection error of a magnetic memory unit by collating information by kinds of equipments of an answer signal, sent from a connected switchboard, to that stored in the memory unit. CONSTITUTION:The CPU of testing device TE sends out a scan signal to connected EPBX. The CPU on the automatic switchboard EPBX side sends information by kinds of predetermined switchboards to the device TE side. Device TE receives the information by kinds of switchboard from EPBX and stores it in memory MEM. Next, tape CMT for EPBX to be tested is selected and loaded on device TE and a testing program is transferred from tape CMT to memory MEM of device TE. At this time, the CPU of device TE collates the information by kinds of switchboards on tape CMT with that having received and stored and when the both agree with each other, correct operation is carried out and when not, a check on whether it has been written at any other part of tape CMT or not is made, so that when it is not found, the lamp of device TE will come on indicating malfunction.
