1. A method for calibrating a non-crystal oscillator in a transceiver unit using a crystal oscillator, comprising the steps of: establishing a time base based upon oscillations of the crystal oscillator; comparing a number of oscillations for the non-crystal oscillator and the crystal oscillator during a known time period; determining an adjustment based upon the established time base and the compared number of oscillations; and controlling operation of the transceiver unit responsive to the adjustment.
