It is connected to the integrated subscriber line test trunk specified by the connection function between maintenance personnel and the exchange switch, and converts the MF/MFC signal input from the subscriber line test stand into a digital signal and sends it to the central processing unit. , an MF/MFC signal transmitting/receiving device that converts a digital signal input from the central processing unit into an MF/MFC signal and sends it to the subscriber line test stand, and the central processing unit initiates connection from the subscriber line test stand. Upon receiving the signal, it connects the MF/MFC signal transceiver M to the integrated subscriber line trunk, and then sends a signal from the subscriber test stand determining that the integrated subscriber test trunk is to be used as the subscriber line test connection trunk. When receiving via the MF/MFC signal transmitting/receiving device M, connect the integrated subscriber line test trunk and the subscriber line test bag M, and when receiving complaints from subscribers or contact from maintenance personnel, MF/MF
Connect the C signal receiving device M to the integrated subscriber line test trunk, and confirm that the integrated subscriber line test trunk is used as a trunk for receiving complaints from subscribers or as an incoming trunk for calls from maintenance personnel. Display on the test stand, connect the subscriber terminal to the integrated subscriber line test trunk to receive complaints or communicate with maintenance personnel, and connect the subscriber terminal from the subscriber line test stand to the integrated subscriber line test trunk for communication between maintenance personnel. When a signal determining the use as a trunk is received via the exchange switch MF/MFC signal transmitting/receiving device and peripheral device control bag M, a connection for communication between maintenance personnel is established.

[For production]

In this way, the integrated subscriber line test trunk is directly connected as a connecting trunk for the incoming and outgoing lines of the subscriber line test stand, and a wide variety of connection types for incoming and outgoing calls on the subscriber line test stand can be connected to the MF.
Or, in the case of an outgoing call using an MFC signal, the subscriber line test stand specifies the connection type to the central processing unit, and in the case of an incoming call, the central processing unit notifies the subscriber line test stand of the incoming call type,
The central processing unit realizes the corresponding connection to the integrated subscriber line test trunk via the exchange switch, so that the connection of the subscriber line test stand, which was conventionally done by three types of trunks, can now be made into just one type of integrated subscriber line test trunk. This can be done on the line test trunk.
