ABSTRACT:
In a communication network, a synchronized over-the-air (OTA) time slot of a base station's polling loop is acquired by a remote station seeking to initiate contact with that base station, such that periodic voice frames may thereafter be transmitted at known intervals between respective radio interfaces of the remote and base stations. A vocoder in the respective remote station is then synchronized to the established remote station OTA slot timing and a vocoder associated with the respective base station is separately synchronized to the established base station OTA slot timing, wherein each respective vocoder transmits and receives voice frames across full-duplex serial interface to and from its radio interface including a locally generated synchronization ("sync") pattern appended in front of a selected number of coded (i.e., compressed) bearer information and control bytes.
