PURPOSE:To exactly measure the traffic of the master station, by providing a means for collecting all the number of times of dial-tone, and the originating accomodating position, from the common control equipment of the master station telephone switchboard, and also a means for measuring the C line ground signal. CONSTITUTION:A sub-office subscriber SUB-S takes up a transmitter and receiver, the marker M of the common control equipment connects the SUB-S with the outgoing trunk OGT extending to the master station, through the switch SW. The OGT stores a dial in the originating register R, and also starts the incoming trunk ICT of the master station. The ICT starts the dial-tone marker DM of the common control equipment through the main LINK, and connects the ICT to the originating register OR of the master station. Ground is supplied to the C line from the OR, and it is measured by the traffic measuring equipment TME through the scanning circuit SCN. Unless a dial from the SUB-S is a call in the sub-office, 2 figures and after are stored in the OR, and the connecting marker CM is started. The CM sends the information such as originating accommodating position, etc. for measuring the traffic, to the TEM through the SCN. In this way, all the number of times of dial-tone of the master station are measured. |
