Abstract: A method and apparatus for communicating between a plurality of asynchronous transmitting and receiving systems using digital streams arranged in multiple access frames comprises a master system, which cycles a counter using a clock reference to generate a master count, and uses the master count to establish a master frame count. A slave system cycles a counter using a clock reference to generate a main count, and uses the main count to establish a main frame count. From a difference between the master frame count and the main frame count of the slave system, a frame count offset value is determined. A slave frame count for the slave system is then established by adding the offset value to the main frame count, and thereby aligning the slave frame count of the slave system with the master frame count and incrementing the slave frame count when the main count is incremented.

Abstract: The asynchronous timing generator is comprised of a clock signal generator that generates a master clock signal. The master clock signal is used by a master clock counter to generate a bit clock. The master clock counter divides the master clock signal's frequency down to a lower frequency. Control signal information is extracted from the data stream's slot-framing to control the use of a predefined count value to a variable counter. The variable counter uses this lower frequency clock signal to generate the sub-bit count clock signal and slot bit numbers. These signals are generated in response to the control signals, coupled to the timer, indicating the different fields of the slot used to resynchronize data recovery in the received stream. In a preferred embodiment, the asynchronous timing generator is used in a communications transceiver device to permit resynchronization of received communications data.
