Object

row 
Describes a modulation profile for an Interval Usage Code
for one or more upstream channels.
Entries in this table are created by the operator.
            
Initial default entries MAY be created at system
initialization time, which could report a value of
'permanent' or 'readOnly' for docsIfCmtsModStorageType.
A CMTS MAY reject the creation of additional Interval
Usage Codes for a modulation profile being defined at
Initialization time.
No individual objects have to be specified in order
to create an entry in this table.
            
Note that some objects do not have DEFVAL clauses
but do have calculated defaults and need not be specified
during row creation.
