             the most recent docsIfCmtsChannelUtilizationInterval.

             Upstream Channel Utilization Index:

             The upstream channel utilization index is expressed as a
             percentage of mini-slots utilized on the physical channel,
             regardless of burst type.  For an Initial Maintenance
             region, the mini-slots for the complete region are
             considered utilized if the CMTS received an upstream
             burst within the region from any CM on the physical
             channel.  For contention REQ and REQ/DATA regions, the
             mini-slots for a transmission opportunity within the
             region are considered utilized if the CMTS received an
             upstream burst within the opportunity from any CM on the
             physical channel.  For all other regions, utilized
             mini-slots are those in which the CMTS granted
             bandwidth to any unicast SID on the physical channel.

             For an upstream interface that has multiple logical
             upstream channels enabled, the utilization index is a
             weighted sum of utilization indices for the logical
             channels.  The weight for each utilization index is the
             percentage of upstream mini-slots allocated for the
             corresponding logical channel.
             Example:
             If 75% of bandwidth is allocated to the first logical
             channel and 25% to the second, and the utilization
             indices for each are 60 and 40, respectively, the

Top      Up      ToC       Page 98 
             utilization index for the upstream physical channel is
             (60 * 0.75) + (40 * 0.25) = 55.  This figure
             applies to the most recent utilization interval.

             Downstream Channel Utilization Index:

             The downstream channel utilization index is a percentage
             expressing the ratio between bytes used to transmit data
             versus the total number of bytes transmitted in the raw
             bandwidth of the MPEG channel.  As with the upstream
             utilization index, the calculated value represents
             the most recent utilization interval.
             Formula:
             Downstream utilization index =
             (100 * (data bytes / raw bytes))

             Definitions:
             Data bytes:    Number of bytes transmitted as data in the

                            interval.
             Raw bandwidth: Total number of bytes available for
                            transmitting data, not including bytes
                            used for headers and other overhead.
