Abstract
Disclosed are techniques for timing correction for a DOCSIS Edge-QAM. Unlike the DTI required at the headend in existing solutions for DOCSIS Edge-QAM timing, the disclosed techniques may use an Edge-QAM timing deeper in to the network. The N-QAM, referring to an Edge-QAM that is deeper in the network, may be in the optical node configured to convert signals from a network headend or hub for delivery to a subscriber network element. The N-QAM device located in the node may include a local clock for deriving a local time for incoming transport streams, modulating the transport streams onto a downstream carrier for delivery to subscriber network elements using the local clock time, and adjusting the local clock time based on an average value of timestamps in the incoming transport streams.
