    Description by circitor

    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'.

    DESCRIPTION
    "This object is generally intended to be used for the creation of
    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.
    Although this object was created to facilitate SCDMA parameter
    adjustment, it may also be used at the vendors discretion for
    non-SCDMA parameter adjustment."
