Abstract: Un método para controlar el consumo de energía en una unidad inalámbrica (10) de abonado que se comunica utilizando tramas repetitivas y es capaz de tener un bucle de abonado de longitudes variables, dando servicio el bucle de abonado a un teléfono situado remotamente con respecto a la unidad de abonado, estando caracterizado el método por: determinar una longitud del bucle para un bucle de abonado a utilizar; proporcionar un valor fijo de corriente al bucle de abonado; seleccionar una tensión para alimentar el bucle de abonado basándose en parte de la longitud del bucle de abonado y en el valor fijo de corriente; y alimentar el bucle de abonado con la tensión seleccionada y la corriente fijada, y mantener la corriente fijada en un valor sustancialmente constante independientemente de la tensión seleccionada, ahorrando así energía al tiempo que se mantiene el valor fijo de la corriente, desactivando selectivamente una pluralidad de componentes no identificados como requeridos para el funcionamiento de la unidad de abonado en un estado determinado, siendo realizada dicha desactivación durante la conexión de una llamada y en sucesivas tramas de tiempos durante las ventanas de tiempo que no son requeridas para las operaciones de tratamiento de la señal.

Abstract: A subscriber unit of a time division multiple access (TDMA) radiotelephone system is, from a power consumption standpoint, reconfigured in each time slot of a TDMA frame to a power consumption tessellation in which subscriber unit circuit components not needed for communication signal processing in that time slot are powered down, and other components are powered up.Some circuit components are powered down by switching their power supply circuits. In order to minimize the extent of circuitry that must be provided to distribute power consumption control signals, other techniques (which utilize circuitry provided for other purposes), such as clock frequency control or power down commands, also are utilized to modify controlled circuit component power consumption without actually controlling power supply circuits. Loop connection length between the subscriber unit and the subscriber's telephone set, or other terminal equipment, is limited to a length which is much less than the length of a radio link on which the subscriber unit operates. Programmable ring frequency logic controls the frequency of a ringing signal generator, and a high frequency ring control signal is switched on and off in the cadence of ringing operation. Also an expansion header is provided to enable serving plural subscriber loop circuits with the same radio equipment for reducing per line power consumption.

Abstract: The present invention provides a method of minimizing synchronization delay in a radiotelephone system between a modular subscriber cluster communicating with a common base station, the modular subscriber cluster receiving repetitive time slots from the base station and having a plurality of frequency-agile modems, the method comprising the steps of: synchronizing a selected one of the modems to a selected time slot of the received time slots; generating a frame sync signal from said selected modem; and distributing said frame sync signal to remaining ones of the plurality of modems.
