ABSTRACT:
A system is described for randomly addressing any one of a plurality of remotely located stations connected by means of an electromagnetic wavepath. At the addressing point an addressing signal, comprising a series of m signal bursts, is generated and coupled onto the wavepath (11), where m is an integer and corresponds to the number of stations the addressed station is away from the addressing point. Each remote station includes means (33, 34, 41, 43) for deleting one signal burst and retransmitting the remaining signal bursts. Each station also includes means (34, 38, 42, 43, 44, 50, 51) for recognizing when only a single signal burst is received and for responding in a prescribed manner. By means of such a "count-down" technique, the m.sup.th station from the addressing station is accessed. it is an advantage of such a system that the addressing circuit is the same at all the remote stations.
