Description: The QAM channel Interleaver capabilities. 'eqamDependency' BIT set to '1' indicates the QAM channel interleave value has dependencies with other QAM channels as indicated in docsIfMCmtsEqamGroupDependencyTable.
'taps8Increment16' set to '1' indicates the support of j = 8, i = 16 interleave.
'taps16Increment8' set to '1' indicates the support of j = 16, i = 8 interleave.
'taps32Increment4' set to '1' indicates the support of j = 32, i = 4 interleave.
'taps64Increment2' set to '1' indicates the support of j = 64, i = 2 interleave.
'taps128Increment1' set to '1' indicates the support of j = 128, i = 1 interleave.
'taps12increment17' set to '1' indicates the support of j = 12, i = 17 interleave.
'tabs128increment2' set to '1' indicates the support of j = 128, i = 2 interleave.
'tabs128increment3' set to '1' indicates the support of j = 128, i = 3 interleave.
'tabs128increment4' set to '1' indicates the support of j = 128, i = 4 interleave.
'tabs128increment5' set to '1' indicates the support of j = 128, i = 5 interleave.
'tabs128increment6' set to '1' indicates the support of j = 128, i = 6 interleave.
'tabs128increment7' set to '1' indicates the support of j = 128, i = 7 interleave.
'tabs128increment8' set to '1' indicates the support of j = 128, i = 8 interleave.
When 'eqamDependency' BIT is set to '1', a set to the interleave PHY parameter of a QAM channels in a dependency group (with docsIfMCmtsEqamGroupDependencyType set to docsPHYParamSameValue), sets the same Interleave value to all QAM channels in the dependency group.
What is docsIfMCmtsEqamDownstreamCapabInterleaver?
A large bitmap enumerating the specific interleaver depth/increment combinations (e.g. taps8Increment16 through taps128increment8) this QAM channel supports, each trading off burst-noise protection against added latency, plus an 'eqamDependency' bit for group-linked interleaver settings. A field engineer references this when choosing an interleaver profile to balance impulse-noise immunity against latency-sensitive services like voice.
