Abstract
A method and computing device for maintaining the stability of the upstream channel quality measurements in an upstream channel bonded system. The method configures a cable modem, that communicates using bonded channels, to periodically exchange ranging messages on the bonded channels, where a bonded channel ranging interval determines a period for the exchange. The method also monitors a signal quality metric for a monitored channel of the bonded channels by periodically retrieving a quality measurement for the monitored channel, a period between each retrieval determined by a channel quality monitoring interval. The method sends an invite ranging message to the cable modem before retrieval of the quality measurement for the monitored channel, and retrieves the quality measurement for the monitored channel. The method bases the signal quality metric for the monitored channel on the quality measurement.
