             This version published as RFC 4546.
             This MIB module revision includes the following
             among others:
             Usage of ifType (205) for upstream logical channels.
             Addition of downstream and upstream utilization
             counters.
             Additional statistics per upstream interface.
             Upstream channel offline configuration mechanism.
             Added MIB support for new DOCSIS 2.0 modulation
             attributes.
             Euro-DOCSIS downstream interleave values.
             Adjustments to RFC 2670 definitions based on
             the MIB review guidelines from the IETF
             Operations and Management Area (OPS)."

             "This data type represents the equalizer data
              as measured at the receiver interface.
              The format of the equalizer follows the structure of the
              Transmit Equalization Adjust RNG-RSP TLV of DOCSIS RFI
              v2.0 :
              1 byte Main tap location 1..(n + m)
              1 byte Number of forward taps per symbol
              1 byte Number of forward taps: n
              1 byte Number of reverse taps: m

              Following are the equalizer coefficients:
              First, forward taps coefficients:
              2 bytes F1 (real),  2 bytes  F1 (imag)
              ...
              2 bytes Fn (real),  2 bytes  Fn (imag)

              Then, reverse taps coefficients:
              2 bytes D1 (real),  2 bytes  D1 (imag)
              ...

              2 bytes Dm (real),  2 bytes  Dm (imag)

              The equalizer coefficients are considered signed 16-bit
              integers in the range from -32768 (0x8000) to 32767
              (0x7FFF).

              DOCSIS specifications require up to a maximum of
              64 equalizer taps (n + m); therefore, this object size
               can get up 260 bytes (4 + 4x64).
              The minimum object size (other than zero) for a t-spaced
              tap with a minimum of 8 symbols will be 36 (4 + 4x8)."

            "List of attributes for a single upstream channel.  For
             DOCSIS 2.0 CMTSs, an entry in this table exists for
             each ifEntry with an ifType of docsCableUpstreamChannel
             (205).
             For DOCSIS 1.x CM/CMTSs and DOCSIS 2.0 CMs, an entry in
             this table exists for each ifEntry with an ifType of
             docsCableUpstream (129).

             For DOCSIS 2.0 CMTSs, two classes of interfaces can be
             defined for this table:
              o Upstream Physical Interfaces: The traditional DOCSIS
                1.x CMTS upstream interface ifType 129 and the DOCSIS
                2.0 ifType 205 that are functional.  In other words,
                interfaces that represent upstream receivers within
                an RF MAC interface.
                Entries of physical interfaces are exposed to the
                management interface with their corresponding
                ifStack hierarchy and are not administratively
                created by this table.

              o Upstream Temporary Interfaces: A fictitious
                interface created for the purpose of manipulating
                physical interface parameters offline, then
                validating prior to updating the target physical
                interface.

             In case of a reinitialization of the managed system,
             physical interfaces values persist while the temporary
             interfaces are not recreated.

             This mechanism helps to minimize service disruptions
             originating in situations where a group of interface
             parameter values need to be consistent with each other
             in SET operations.  A temporary buffer
             (temporary interface) is provided to allow the CMTS
             to validate the parameters offline."

        DESCRIPTION
            "This object is only used for the creation of a temporary
             upstream row with the purpose of updating the parameters
             of a physical upstream channel entry.

             The following restrictions apply to this object:
             1. This object is not writable for physical interfaces.
             2. Temporary interface entries are only created by a SET
                of this object to createandWait(5).
             3. ifAdminStatus from the Interface MIB RFC 2863 is used
                to take a physical upstream channel offline, to be
                consistent with DOCSIS 1.x operation, as indicated in
                RFC 2670.
                In addition,
                 o ifAdminStatus 'down' is reflected in this object
                   as 'notInService'.
                 o ifOperStatus 'down' while ifAdminStatus 'up' is
                   reflected in this object as 'notInservice'.
             4. Temporary created rows MUST be set to 'active' with
                the purpose of validating upstream parameter
                consistency prior to transferring the parameters to the
                physical interface.

             Below is a mandatory procedure for adjusting the values
             of a physical interface:
             1. Create a temporary interface entry through an SNMP SET
                using 'createAndWait'.  At this point, the RowStatus
                reports 'notReady'.
                The Manager entity uses an ifIndex value outside the
                operational range of the physical interfaces for the
                creation of a temporary interface.
             2. Set the docsIfUpChannelCloneFrom object to the ifIndex
                value of the physical row to update.  Now
                docsIfUpChannelStatus reports 'notInService'.
             3. Change the upstream parameters to the desired values
                in the temporary row.
             4. Validate that all parameters are consistent by setting
                docsIfUpChannelStatus to 'active'.  A failure to set the
                RowStatus to 'active' returns the error 'commitFailed',
                which means the parameters are not compatible with the
                target physical interface.
             5. With docsIfUpChannelStatus 'active', transfer the
                parameters to the target physical interface by setting
                the object docsIfUpChannelUpdate to 'true'.
             6. Delete the temporary row by setting
                docsIfUpChannelStatus to 'destroy'."

             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
             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
                            docsIfCmtsChannelUtilizationInterval.

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