This attribute is the DS OFDM channel utilization measured by the CCAP across all profiles over the configured utilization interval. The CCAP must report DS utilization metric of the channel that conforms to the following requirements: - report a value for OfdmChannelUtilization <= 1% when no user traffic is forwarded on the channel and MMM traffic is known to be less than 1% of the channel capacity - report a value for OfdmChannelUtilization >= 99% when forwarded traffic completely saturates the channel. - report a value for OfdmChannelUtilization which increases linearly with traffic volume increase and is accurate within 1% of the channel capacity for any given traffic mix (ratio of packets for a given OFDM profiles, packet size, traffic pattern, etc.), which results in nearly all full codewords as the maximum channel capacity is reached. Note: The channel capacity is defined as the largest ProfileFullChannelSpeed value for this channel.
