Reference numeral 12 denotes a measuring instrument, respectively.

The hardware to which the present invention is applied, as shown in FIG. 1, connects the subscriber connection device 2 to the subscriber 1, the switch device 5 to the subscriber connection device 2, and the switch device. The relay line connecting device 4 is connected to the relay line 3 and the relay line connecting device 4, and the subscriber line control device 6 is connected to the subscriber connecting device 2, and the relay line controlling device 7 is connected to the connecting device 4, respectively. The operation / maintenance control device 9 to the subscriber control device 6, the switch control device 8, and the trunk line control device 7, and to an operator to the operation / maintenance control device 9; It is configured by connecting the operator terminal 10 for transmitting and receiving information, connecting the relay line test connection device 11 to the switch device 5 and connecting the meter 12 to the relay line test connection device (11).

A subscriber device 2 connected to the subscriber 1, a relay line connecting device 4 to which the relay line 3 serving as a path to a counterpart exchanger is connected, and a switch device providing connection capability between the subscriber and the relay line (5) is included in the call path section constituting the call route.
