SPECTRUM ANALYSIS AND PLANT DIAGNOSTIC TOOL FOR COMMUNICATIONS SYSTEMS

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.
