Abstract

PURPOSE:To realize the transmission for the monitor signal of the private line terminal to the junction line without any distortion for the storage subscriber outside the teritory by providing the secondary exchange circuit network which gives the exchange connection exclusively for the monitor signal of the subscriber state. CONSTITUTION:For private line terminal 21 which desires the transmission of the terminal state signal to the junction line in the form as it is, the scanning result of scanning circuit 34 is written into the memory in secondary exchange circuit network 38 in correspondence to the terminal numbers in sequence. Then the scanning result written is read out at the time when the corresponding talking state in the main exchange circuit network 26 is delivered to the signal insertion position corresponding to the channel in question on the junction line having the exchange connection via the exchange action of network 38. The result read out is then distributed to one of corresponding digital multiple junction line interface units 30-1 and 30-2 through multiple isolation circuit 42 to be then inserted into the signal insertion position of the desired interface unit.
