| Description | The QAM channel frequency capabilities.
'qamDependency' BIT set to '1' indicates the QAM channel
frequency value has dependencies with other QAM channels
and an entry that includes this QAM channel is in
in docsDrfGroupDependencyTable for the PHY
parameter 'frequency'.
'adjacentChannel' BIT set to '1' indicates the QAM channel
frequencies in the dependency group (DEPI TSID group) are
adjacent and constrained in a frequency range based on
the number of QAM channels in the dependency group.
'adjacentChannelOrder' BIT set to '1' indicates the QAM
channel frequency adjacency is based in the QAM channel
sequence like entPhysicalParentRelPos in EntPhysicalTable
or other vendor sequence.
e.g., a dependency group of four QAM channels
with 'adjacentChannelOrder' BIT set to '1':
The 4th QAM channel in the sequence gets a frequency
assignment f + 1*bandwidth when the frequency value of
the 3rd QAM channel in the sequence is set to f.
Similarly the 1st QAM channel in the sequence gets a
frequency assignment of f - 2*bandwidth and the 2nd QAM
channels gets a frequency of f -1*bandwidth.
'adjacentChannel' 'adjacentChannelOrder' BITs may be set to
'1' when a dependency group includes the QAM channel
of this M-CMTS Downstream interface and the value of the
object docsDrfGroupDependencyType is
docsDrfPhyParamAdjacentValues.
'adjacentChannel' BIT may be set to '1' if
'qamDependency' BIT is set to '1'. The same way,
'adjacentChannelOrder' BIT may be set to '1' and implies
'adjacentChannel' BIT is set to '1'. |
