Abstract:
In a telecommunications subscriber unit, a method of 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 method comprising the steps of:a) receiving and monitoring each of the telephone signals to detect a data signal in one of the telephone signals, wherein at least one of said telephone signal is a 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; and 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; b) encoding the data signal to generate a coded signal; c) checking an assignment status of the information slots responsive to detection of the data signal, the assignment status indicating whether each carrier and each information slot is unassigned or assigned to another one of the telephone signals; d) locating a predetermined number of unassigned sequential information slots; e) forming the communication channel from the unassigned sequential information slots; and f) modulating the coded signal on the communication channel; whereby the receiving and monitoring step a) further includes inhibiting the data signal identification of the first type until the forming step e) forms the communication channel.
