1. A method performed by a subscriber unit, the method comprising:
- receiving a burst on a traffic channel of an air-interface protocol;
demodulating the received burst;
determining whether the received burst is a correctly received traffic burst of the air-interface protocol; and
if the received burst is not a correctly received traffic burst, then determining whether the received burst is a calibration burst.

Abstract
Calibration signals can be sent on a traffic channel without interrupting a connection between two radios. In one embodiment, the present invention includes receiving, at a second radio, a first traffic signal transmitted on a traffic channel by a first radio during a first time interval, receiving, at the second radio, a calibration signal transmitted on the traffic channel by the first radio during a second time interval, and receiving, at the second radio, a second traffic signal transmitted on the traffic channel by the first radio during a third time interval, wherein the traffic channel supports a connection between the first and second radios.

6. A subscriber unit comprising:
-
a receiver to receive a burst on traffic channel of an air-interface protocol;
a demodulator coupled to the receiver to demodulate the received burst;
a processor coupled to the demodulator to determine whether the received burst is a correctly received traffic burst of the air-interface protocol, and, if the received burst is not a correctly received traffic burst, then to further determine whether the received burst is a calibration burst. - View Dependent Claims (7, 8, 9, 10)
