As part of a preferred communication protocol, base stations which are synchronized to a PSTN of a wireless communication network, periodically transmits a preamble. A remote detects the preamble and, upon verification of the data contained in the base station transmission, sets its counter to an initialized state based on the received preamble. An early/late analysis of each subsequently received base station timing pulse is used to adjust both the mobile station timing and to adjust the output frequency of the mobile station master clock and codec clock to effectively maintain end to end synchronization with the respective base station and the PSTN throughout the duration of an established communication link.
