DESCRIPTION
"Administrative configuration of lock bits for EQAM
channels PHY parameters.
A BIT set of this object is meaningful when the same BIT
set in docsIfMCmtsEqamDownstreamDevicePhyParamLock is set
to '0'. Therefore, a SET to this object when the entry
value of docsIfMCmtsEqamDownstreamDevicePhyParamLock is
set to '1' returns error 'wrongValue'.
When a PHY parameter BIT in this object is set to '1'
the QAM channel PHY parameter in
docsIfMCmtsDepiSessionConfigTable is locked
for SNMP SETs returning error 'notWritable' on those
attempts.
Sets to this object could be complex; as a rule of
thumb, SNMP agents ignore bits that are not recognized
(e.g., extensions). An attempt to set BITs while
docsIfMCmtsEqamDownstreamDeviceConfigPhyParamLock is set
to '1' is rejected and the error code 'wrongValue' is
returned."

**Classification**: MIB object for network management
