INTERFACE SYSTEM BETWEEN LINE AUTOMATIC TRANSMISSION MEASURING DEVICE AND EXCHANGE

摘要

PURPOSE:To reduce the memory capacity and to improve the operating efficiency, by transmitting a signal of a register of MF signal form two times as two sets of MF signals from an outgoing trunk of a line automatic transmission measuring device to an incoming trunk of an exchange and expressing one character with the 2 sets of MF signals. CONSTITUTION:A line test number inputted from a typewriter 4 is stored in a memory of a controller 3. The controller 3 controls a run signal through a control line 12 to the outgoing trunk 2 by using this input and controls a register signal through an MF transmission/receiving control line 13. As to the name of route of the line test number stored in the memory of the controller 3, the signals corresponding to the 1st and the 2nd combination to one character signal are transmitted twice according to the combination list represented in the form of MF signal. This signal passes through the outgoing trunk 2 from an MF transmitter 5 and is transmitted to the incoming trunk 6 of the exchange through a communication line 14 as the register signal.
