Abstract: A subscriber unit (10) of a time division multiple access (TDMA) radiotelephone system is reconfigured in each time slot to a power consumption tessellation in which circuit components (12, 13, 21, 29, 56, 57, 58) not needed for communication signal processing in that time slot are powered down. In order to minimize the extent of circuitry that must be provided to distribute power consumption control signals, techniques such as clock frequency control (26, 30, 70) or power down commands (31, 67, 68) are utilized to modify controlled circuit component power consumption without actually controlling power supply circuits. Programmable ring frequency logic (20) controls the frequency of a ringing signal generator (58), and a high frequency ring control signal (70) is switched on and off in the cadence of ringing operation. An expansion header is provided to enable serving plural subscriber loop circuits with the same radio equipment for reducing per line power consumption.
