docsDrfDownstreamCapabJ83Annex
Module: DOCS-DRF-MIB
OID (symbolic): DOCS-DRF-MIB::docsDrfDownstreamCapabJ83Annex
OID (numeric): 1.3.6.1.4.1.4491.2.1.23.1.3.1.6
Node type: OBJECT-TYPE
Type: Bits
Access: read-only
Description: The QAM channel J.83 Annex Capabilities. 'qamDependency' BIT set to '1' indicates the QAM channel J.83 Annex value has dependencies with other QAM channels as indicated in docsDrfGroupDependencyTable.
'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 'qamDependency' BIT is set to '1', a set to the J.83 Annex PHY parameter of a QAM channels in a dependency group (with docsDrfGroupDependencyType set to docsDrfPhyParamSameValue), sets the same J.83 Annex value to all QAM channels in the dependency group.
What is docsDrfDownstreamCapabJ83Annex?
This BITS value reports which ITU-T J.83 Annex QAM standards (Annex A, B, or C) the downstream QAM channel supports, along with a qamDependency bit for cross-channel ties. An operator selecting the QAM standard to match regional cable plant requirements (Annex A for Europe, Annex B for North America, Annex C for Japan) uses this to confirm hardware support before configuring the channel. A channel reporting annexB set to 1 confirms it can be configured for North American DOCSIS deployments; if qamDependency is also set, that Annex choice is enforced across its whole dependency group.
