Abstract

PURPOSE:To enable to save power consumption, by omitting the part producing the signal for the absence of information to be sent. CONSTITUTION:The monitored station (2-1) detects the presence of the information in waiting to deliver and it provides the means to alter the connection of the line loop (6-1) with the result of detection. If the information in waiting is present, the call line (4-1) is connected to the reception section (22-1) via the terminals 61 and 64, and the information line (5-1) is connected to the transmission section (21-1) via the terminals 62 and 63. If the information in waiting is absent, the call out line (4-1) is connected so that it constitutes the line loop with the infomation line (5-1) via the terminals 61, 66, 65, 62. With this condition, when the call out signal is delivered and it is delivered to the call out line (4-1), the call out signal returns to the monitor station 1 via the line loop (6-1) and information line (5-1).
