| 14. A method for ensuring spectral compatibility of data signals, comprising the steps of:
receiving an initialization signal at a transceiver;
storing predefined data at a transceiver prior to the receiving step;
combining a value of the predefined data with a measurement of the initialization signal;
calculating a value based on the combining step;
comparing the calculated value to a threshold;
automatically determining, based on the comparing step, whether a data signal to be communicated by the transceiver in the
data phase will be spectrally compatible, if the data signal is transmitted at a data rate of the initialization signal; and
automatically selecting a data rate for the data signal based on the determining step thereby ensuring that the data signal
is spectrally compatible.
