Abstract:
1. 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; the subscriber unit comprising: detector means for receiving and for monitoring each of the telephone signals to detect a data signal in one of the telephone signals; encoding means for encoding the data signal to generate a coded signal; control means for checking an assignment status of the information slots responsive to detection of the data signal and for locating a predetermined number of unassigned sequential information slots for a predetermined bandwidth, the assignment status indicating whether each information slot is unassigned or assigned to a respective one of the telephone signals; channel forming means for forming the communication channel from the unassigned sequential information slots; and means for modulating the coded signal on the communication channel; whereby the subscriber unit also receives at least one reconstructed telephone signal having a response data signal from a received RF carrier, each reconstructed telephone signal and each respective telephone signal being a channel pair; the data signal has a corresponding data signal identification of a first type, and the response data signal has a corresponding data signal identification of a second type; and the detector means inhibits the data signal identification of the first type until the communication channel is formed.
