Abstract
The encoder which preferably produces a transmitted digital word which serves as an activation code for a single receiver or a group of receivers. The activation code effects only the receiver(s) that have previously detected their digital address and are therefore prepared to enter a message receive state. The activation code transmitted by the encoder will cue the receiver(s) simultaneously thereby allowing the encoder to send a single message to a plurality of receivers. The activation code also allows the encoder to interleave messages to receivers by utilizing the customary transmitter down time in a single message transmission. During this down time, the activation code allows the transmitter to begin transmission of a second message to a second receiver. The use of the activation code to interleave messages is especially important in tone and voice transmissions since it significantly increases the efficiency of a heavily loaded system.
