摘要： An apparatus and method is disclosed to calculate the actual received desired channel power from the downstream transmit power of a Cable Modem Termination System (CMTS) when operating at the nominal line voltage and/or at the normal room temperature as per the DOCSIS specification. A Set-top Device produces a Downstream Power Management (DPM) gain measurement signal having a known power level. The Set-top Device embeds the DPM gain measurement signal onto a received downstream multi-channel communication signal. After embedding the DPM gain measurement signal onto the downstream multi-channel communication signal, the Set-top Device downconverts the combined DPM gain measurement signal and downstream multi-channel communication signal to recover one or more communication channels containing information of a broadcast. The Set-top Device measures a power level of a representation of the DPM gain measurement signal embedded within the one or more communication channels containing the information of the broadcast to determine a Set-top Device gain. The Set-top Device measures a power level of the one or more communication channels containing the information of the broadcast. The Set-top Device calculates the actual received desired channel power from the downstream transmit power of the CMTS based on the Set-top Device gain and the power level of the one or more communication channels containing the information of the broadcast.

摘要： A system, method, and apparatus to allow an operator of a broadcast communication system, such as a cable television or satellite television service to provide some examples, to diagnose performance of this communication system remotely. The operator of a first communication device, such as a cable modem termination system (CMTS) to provide an example, may remotely diagnosis performance problems, or potential performance problems, occurring at a second communication device, such as a cable modem (CM) to provide an example, or a group of second communication devices. For example, the operator of the first communication device may view a spectrum analysis of communication signals being routed to, processed by, and/or provided by the second communication device, or group of second communication devices, to diagnose the performance problems, or the potential performance problems, in real time.
