ABSTRACT:
An improved quasi-duplex time division multiplexed (TDM) communication system provides for transmission by a talker until an interrupt command for role reversal is transmitted by a listener. Preferably, the time allocated for voice transmission is greater than the time allocated for command transmission. In this manner, the primary feature of full-duplex communications is provided simply while conserving spectrum.
