Abstract

PURPOSE:To enable polling without giving adverse effect on line during communication, by choking all the circuits including lines of terminal stations in advance and making it after the end of calls on the entire lines, when polling is made from a communication master station. CONSTITUTION:When polling is made from a communication master station 1, the presence of lines during communication is confirmed with a communication signal 4, and when the lines during communication are present, a multiplex line choking signal 5 is transmitted to the entire system to inhibit new connection to an incoming line from a branching staion 2. Further, when no talking signal is present to the terminals of the branching staion, the braching station 2 transmits a terminal line choking signal 6 to terminals 31-3n to inhibit new calls from the terminal stations 31-3n, avoiding the production of new calls in all the lines. Thus, the master station 1 wait for the restoration of lines transmitting the talking signal 4 already during talking and delivers a polling signal 7.
