Abstract
PURPOSE:To enable to establish the line monitor control in time sharing exchanger system with less number of wirings, by forming the fixed pattern information as the line status signal and detecting it. CONSTITUTION:The line status signal SCN detected at the subscriber circuit LC is inputted to the coder COD to form a given fixed pattern information and fed to the time switch T-SW1. Next, the communication information of each subscriber or line status information is sequentially written in the communication memory in the address corresponding to each subscriber with the control of the write-in control circuit. Further, each address of communication memory is circulatingly and sequentially read in with the line information read-in control circuit RCC, and when the fixed pattern information is read in from the same address, the status information of the line corresponding to the address is transferred to the central processing unit CPU. Thus, the monitor unit less in wirings can be obtained.
