A cable television diagnostic method for a cable television network consistent with certain embodiments involves sending a polling message to a plurality of modems forming a part of a plurality of television set top boxes from a cable television headend via a cable television cable connection to the set top boxes; wherein the polling message instructs the cable television set top boxes to obtain at least one operational parameter of each of the television set top boxes; receiving a plurality of response messages from the cable television set top boxes, each containing the at least one operational parameter of the television set top boxes; determining that one of the operational parameters from one of the television set top boxes is outside of a specified range of values; and aggregating the operational parameters of the plurality of set top boxes received in the response messages to determine if the same operational parameter is outside the range of specified values for more than the one of the television set top boxes. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
