Zusammenfassung:PURPOSE:To simplify and automate the test by comparing a bit pattern of a tone generator and an ON/OFF pattern provided with a signal tone designated by designation information. CONSTITUTION:Designation information is inputted to a management processor MPR5. A designated digital signal is transmitted from a prescribed tone generator TNG7 by using the information. A line circuit LC2 converts it into an analog signal tone, which is received by a tone detector TND11. The TND11 converts the tone into the ON/OFF pattern, which is read from the MPR5 by scanning. The result of read and the content of the signal tone designated by the MPR5 are collated to confirm whether the contents of the signal tone is normal or abnormal.
