摘要： A communication system includes a first data processing unit (100a), a second data processing unit (100b), and a data link line (13, 116a, 116b) provided between the first data processing unit and the second data processing unit. A first monitor terminal (12a) controls the first data processing unit and monitors the first and second data processing units. A second monitor terminal (12b) controls the second data processing unit and monitors the first and second data processing units. A first switching circuit (30a) is coupled to the first data processing unit, the first monitor terminal and the data link line, and selectively connects two of the first data processing unit, the first monitor terminal and the data link line. A second switching circuit (30b) is coupled to the second data processing unit, the second monitor terminal and the data link line, and selectively connects two of the second data processing unit, the second monitor terminal and the data link line. The first switching circuit has a mode in which the first terminal is connected to the data link line and the second switching circuit has a mode in which the second data processing unit is connected to the data link line so that the first monitor terminal monitors the second data processing unit.

摘要： A supervisory system for a primary group digital transmission line wherein a terminal repeater (LTE0) transmits, over a supervisory line (L), address information designating an intermediate repeater (REP0,1,2,--) and line within the intermediate repeater to be monitored while the line is in a normal, in-service condition. The terminal repeater (LTE0) and intermediate repeaters (REP0,1,2,--) are cascaded connected by way of the supervisory line (L). The terminal repeater (LTE0) and each of the intermediate repeaters (REP0,1,2,--) include amplifiers (T₁,T₂--,R₁,R₂,--) that receive and send information along the transmission line, and have a monitor output. The monitor output is processed by an error monitor (EM) within the terminal repeater (LTE0) and in each of the intermediate repeaters (REP0,1,2,--) and the results of the error monitoring provided to the supervisory line in response to polling by the terminal repeater (LTE0).
