1. A modem, comprising:
a processor configured to identify a reference point for an upstream calibration signal in view of upstream scheduling information;
a transmitter configured to generate the upstream calibration signal at the reference point; and
a detector configured to:
determine a calibration property in view of the upstream calibration signal, wherein the processor is further configured to identify at least one calibration parameter for the transmitter in view of the calibration property; and
detect signals of other cable modem transceivers within a particular time slot, the upstream calibration signal being generated when signals received from the other cable modem transceivers are detected to be within a series of subsequent particular time slots with a magnitude below a threshold.
