摘要

Summary of the stability of quality assurance measurement of flow channel in an opposite connection system of flow channel contrast using a multiplier of expiry T4, a method and a computing device to maintain the stability of measurements of the quality of the channel The amount in the system of a channel connected upstream.The method configures a cable modem that communicates using a combination of channels, periodically exchange messages that vary in the connected channels, where a channel on which varies the interval determines a time period for the exchange.The method also monitors a signal quality metric to a channel part of the connected channels recovering periodically a measure of quality for the channel monitored, a period between each recovery determined by a range of monitoring quality of the channel.The method sends an invitation message to the varying cable modem before the recovery of the quality measurement for the channel monitored, and recovers the quality measurement for the channel being monitored. The method is based on the measure of signal quality for the channel is monitored in the measurement of quality.
