    DESCRIPTION
"This is the MIB Module for DOCSIS 2.0 compliant Radio
 Frequency (RF) interfaces in Cable Modems (CM) and
 Cable Modem Termination Systems (CMTS)."
    REVISION "0204260000Z"
    DESCRIPTION
"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."
    REVISION "0203170000Z"
    DESCRIPTION
"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."
    REVISION "0202070000Z"
    DESCRIPTION
"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. "
    REVISION "0111200000Z"
    DESCRIPTION
"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. "
    REVISION "0102230000Z"
    DESCRIPTION
"Modified by Rich Woundy to use IPv6-friendly
 address objects, to accommodate EuroDOCSIS, and
 to correct the SYNTAX of various objects."
    REVISION "9908190000Z"
    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."

"This object is generally intended to be used for the creation of

 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 vendor's discretion for
    non-SCDMA parameter adjustment."

 the TFTP option file (Cable Modem implementation).
 In the Cable Modem Termination system, read-only entries

 An entry in this table must not be removed while it is

 An entry in this table should not be changeable while
 it is referenced by an entry in docsIfCmtsServiceTable.
