Abstract From the Canadian patent

of the Invention, A radio communication receiver decodes digital signals transmitted over a radio link and is capable of altering the bit rate of the receiver to match the bit rate transmitted from a remote location. The receiver includes a receiver portion 21 receiving radio signals and producing a received signal. A microprocessor 26 is used for decoding the received signal. The microprocessor (26) is responsive to a bit rate signal that is generated by a programmable divider (33). The microprocessor (26) is adapted to detect a predetermined code signal to alter the timing characteristic of the bit rate signal for generating a bit rate signal at a second rate for decoding received signals …
