            "This is the MIB Module for DOCSIS 2.0 compliant Radio

        DESCRIPTION
            "pre-RFC draft v5: 
             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.
             Modified by Rich Woundy to use IPv6-friendly
             address objects, to accommodate EuroDOCSIS, and
             to correct the SYNTAX of various objects."

        DESCRIPTION
            "Initial Version, published as RFC 2670.
             Modified by Mike StJohns to fix problems identified by
             the first pass of the MIB doctor.  Of special note,
             docsIfRangingResp and docsIfCmtsInsertionInterval were
             obsoleted and replaced by other objects with the same
             functionality, but more appropriate SYNTAX."

             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.

             Although this object was created to facilitate SCDMA parameter
             adjustment, it may also be used at the vendor's discretion for

              the most recent docsIfCmtsChannelUtilizationInterval.

              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)."
