Abstract:
A bearer channel modification system for a multiple access spread-spectrum communication system including a plurality of information signals each having several different channel rates which information signals are transmitted as a plurality of message code channels over an Radio Frequency (RF) channel as a Code Division Multiplexed (CDM) signal, each of the plurality of message code channels being able to convey information at a predetermined information channel rate, the system comprisingmeans for providing a plurality of call type signals corresponding to the information signal rates for the information signals;a transmitter including a first information channel mode modification means responsive to the call type signal for changing the information signal from a first one of the message code signals to a second one of the message code signals which second message code signal has a different information channel rate than the first message code signal; anda receiver including a second information channel mode modification means responsive to the call type signal for changing a received information signal from the first message code signal to the second message code signal to receive the information signal at the different information channel rate.
