Abstract
A cable access unit (CAU) (60) capable of monitoring power levels for a plurality of channels couples a television (80) and communication equipment (70) to an operations and maintenance center (OMC) (20). At some determined interval, the OMC (20) determines the need to measure the television signal at some particular subscriber's location and sends a message to the CAU (60). The CAU (60) determines if the communications equipment is in use. If not, the CAU receiver is tuned to the channel, and samples and digitizes the power level. The digitized power level is assembled into a message packet and transmitted to the OMC (20).
