Abstract: A multiple converter system is provided for a remote user in a cable communications system. The converters at the user location are linked together via a splitter. One converter operates as a master converter transmitting a master control signal to the other converters, designated as slave converters. The slave converters are actuated only upon reception of the master control signal. The master control signal is interrupted by the master converter only when it transmits data upstream to the central office or when one of the slave converters is required to transmit data. A slave converter notifies the master converter of the need to transmit data by a slave signal. A transmitter unit is automatically activated for transmitting data upstream upon the absence of the master signal on the bus.
