      Modified by David Raftus to add channel utilization related objects,
      upstream channel equalization related objects, a cmts upstream minislot
      counter table, a cmts downstream byte counter table, 64 bit versions of
      existing 32 bit docsIfSigQTable objects, and perform some editorial   
      adjustments.
      pre-RFC draft v4:
      Modified by David Raftus to fix docsIfUpChannelWidth range 
      in  compliance statements to accommodate 6.4Mhz channel at 
      5.12 Msymbol/sec. Also adjusted description of 
      docsIfUpChannelStatus to use correct rowStatus terminology.
      pre-RFC draft v3:
      Modified by David Raftus to add new textual convention
      describing upstream modulation status. Also clarified
      some object descriptions, fixed error in
      docsIfSignalQualityEntry, fixed upstreamTable compliance
      statements.
      pre-RFC draft v2:
      Modified by David Raftus to add capability to adjust
      and verify upstream channel parameters as a group.
      Also adjusted syntax and clarified descriptions of
      selected objects.
      pre-RFC draft v1:
      Modified by Aviv Goren and David Raftus to accommodate 
      Docsis 2.0 Advanced Phy capabilities, as well as to
      incorporate objects from the docsIfExt mib.

            a temporary inactive upstream row for the purpose of adjusting
            the SCDMA channel parameters of an active upstream row. 
            The recommended procedure is:
            1) Create an inactive row through an SNMP SET using createAndWait(5).
               Use an ifIndex value outside the operational range of the system.
            2) Set the docsIfUpChannelCloneFrom field to the ifIndex value of
               the active row whose SCDMA parameters require adjustment.
            3) Adjust the SCDMA parameter values using the new temporary inactive
               row.
            4) Update the active row by setting object docsIfUpChannelUpdate to
               TRUE. This SET will fail if the adjusted SCDMA parameters are not
               compatible with each other.
            5) Delete the temporary row through an SNMP SET using DELETE.
            
            The following restrictions apply to this object:
            1) This object must contain a value of active(1) for active rows.
            2) Temporary inactive rows must be created using createAndWait(5).
            3) The only possible status change of a row created using 
               createAndWait(5) (ie notInService(2)) is to destroy(6).
               These temporary rows must never become active.
            4) A status transition from active (1) to destroy (6) is not
               permitted. Entries with docsIfUpChannelStatus set to active(1) 
               are logically linked to a physical interface, not temporarily 
               created to clone parameters. The Interface MIB (RFC 2863)
               ifAdminStatus should be used to take an Upstream Channel offline.

            Upstream Channel Utilization Index:
            The upstream channel utilization index is expressed as a 
            percentage of minislots utilized on the physical channel, regardless 
            of burst type. For an Initial Maintenance region, the minislots 
            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    
            minislots 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 minislots 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 minislots 
            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 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)) = 
            (100 * ((raw bytes - stuffed bytes) / raw bytes))
            
            Definitions:
            Data bytes: Number of bytes transmitted as data in the                            
                        docsIfCmtsChannelUtilizationInterval. 
            Stuffed bytes: Number of filler bytes transmitted as non-data in the 
                           DocsIfCmtsChannelUtilizationInterval.
            Raw bandwidth: Total number of bytes available for transmitting data,
                           not including bytes used for headers and other overhead.
            Raw bytes: (raw bandwidth * docsIfCmtsChannelUtilizationInterval).";
