Abstract
In a particular embodiment a method of collecting and processing modem data is provided. The method includes, during training of a broadband modem, sending a series of tones within a frequency transmission band of the broadband modem, receiving the transmitted series of tones at a receiving broadband modem, receiving a measurement value, determining a transmission loss for each of the series of tones by comparing the predetermined transmission power level, and the received measured power level, performing a statistical match comparison between each of the received tone signals and a plurality of different computer models of a single transmission facility having various bridge taps connected to the single transmission facility, and determining a best fit between each of the received tone signals and one of the plurality of the bridge tap computer models. The series of tones have a predetermined transmission power level.
