Abstract

PROBLEM TO BE SOLVED: To detect the abnormality in data level deterioration of master machine trunk line by detecting the data level of the master machine trunk line connected to a master machine, comparing it with the data level of a reference value which is previously registered and displaying a comparison result on the display part of a janitor room master machine. SOLUTION: When a data level detection operation is executed in the operation part 23 of a janitor master machine 20, the janitor room master machine 20 transmits data level detection operation information to a control machine 10. The control machine 10 outputs data level detection information to a master machine 40 through a trunk line 4 and inputs detection information to the control machine 10 as received information from the trunk line 4. The control machine 10 compares the data level of received information from the trunk line 4, which a data level detection circuit 124 detects, with the data level of a reference value which is previously registered in a level information operation control part 14, and the compared data level is transmitted to the janitor room master machine 20. The janitor room master machine 20 displays the situation of the data level in a janitor room master machine display part 24.
