Abstract:
1. A method for identifying an origin of a captured DOCSIS upstream burst, the method comprising: (a) acquiring an upstream channel descriptor associated with a DOCSIS upstream channel, the upstream channel descriptor including at least one burst type; (b) generating at least one preamble RF waveform corresponding to the at least one burst type of the upstream channel descriptor acquired in step (a); (c) capturing an upstream burst associated with the DOCSIS upstream channel; (d) correlating a preamble portion of an RF waveform of the upstream burst captured in step (c) with the at least one preamble RF waveform generated in step (b), for identifying a burst type of the upstream burst captured in step (c); (e) extracting a customer premise equipment MAC address from the upstream burst captured in step (c) using the upstream channel descriptor acquired in step (a) and the burst type identified in step (d); and (f) identifying, using a database of subscribers, the origin of the captured DOCSIS upstream burst from the customer premise equipment MAC address extracted in step (e).
