Two related voiceband compression techniques are employed in order to enable an RF subscriber unit to accommodate data signals of high speed voiceband modems and FAX machines. A High Speed Codec enables the subscriber unit to pass voiceband modem and FAX transmissions at up to 9.6 kb/s. An Ultra-High Speed Codec supports voiceband modem and FAX transmissions up to 14.4 kb/s. The High Speed Codec operates using three 16-phase RF slots or four 8-phase RF slots, and the Ultra-High Speed Codec operates using four 16-phase RF slots. Because these codecs transmit information over several RF slots which can be contiguous, the slots within RF communication channels are dynamically allocated. The Dynamic Time slot/Bandwidth Allocation feature detects and monitors the data transmission and forms a data channel from the necessary number of slots.
A telecommunications subscriber unit for receiving a plurality of telephone signals and for transmitting each of the telephone signals on a respective communication channel, wherein each communication channel is formed on at least one transmit radio frequency (RF) carrier, each RF carrier having a plurality of information slots and at least one of the information slots is assigned to one of the telephone signals so that the one of the telephone signals is modulated on the RF carrier;
A telecommunications subscriber unit for receiving a plurality of telephone signals and for transmitting each of the telephone signals on a respective communication channel wherein each communication channel is formed on at least one transmit radio frequency (RF) carrier, each RF carrier having & plurality of information slots and at least one of the information slots is assigned to one of the telephone signals so that the one of the telephone signals is modulated on the RF carrier;
The subscriber unit as recited in claim wherein each RF carrier includes for information slots, each information slot includes a guard band, and the communication channel is formed with one guard band.
A subscriber unit for processing a plurality of telephone signals on a respective communication channel, wherein each communication channel is formed from at least one of a plurality of information slots on a radio frequency (RF) carrier, the subscriber unit comprising:
