Module: DOCS-IF-M-CMTS-MIB
OID (symbolic): DOCS-IF-M-CMTS-MIB::docsIfMCmtsEqamDownstreamCapabJ83Annex
OID (numeric): 1.3.6.1.4.1.4491.2.1.6.1.3.2.1.6
Node type: OBJECT-TYPE
Type: Bits
Access: read-only
Description: The QAM channel J.83 Annex Capabilities. 'eqamDependency' BIT set to '1' indicates the QAM channel J.83 Annex value has dependencies with other QAM channels as indicated in docsIfMCmtsEqamGroupDependencyTable.
'annexA' set to '1' indicates J.83 Annex A support. 'annexB' set to '1' indicates J.83 Annex B support. 'annexC' set to '1' indicates J.83 Annex C support.
When 'eqamDependency' BIT is set to '1', a set to the J.83 Annex PHY parameter of a QAM channels in a dependency group (with docsIfMCmtsEqamGroupDependencyType set to docsPHYParamSameValue), sets the same J.83 Annex value to all QAM channels in the dependency group.
What is docsIfMCmtsEqamDownstreamCapabJ83Annex?
Reports which ITU-T J.83 annex modes (A, B, and/or C) this QAM channel can operate in, plus an 'eqamDependency' bit indicating Annex selection is tied to sibling channels in its group. Since Annex choice (A for DVB-style Europe, B for North American cable) drives symbol rate and channel width defaults, an operator checks this before reconfiguring a channel for a different regional standard.
