qamChannelAnnexMode

Module: SCTE-HMS-QAM-MIB

OID (symbolic): SCTE-HMS-QAM-MIB::qamChannelAnnexMode

OID (numeric): 1.3.6.1.4.1.5591.1.11.5.3.1.1.1.1.8

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: Specifies the ITU-T standard supported by the QAM channel

annexA - standard specified by Annex A of ITU-T J.83 annexB - standard specified by Annex B of ITU-T J.83 annexC - standard specified by Annex C of ITU-T J.83 Other - other standard that may apply.

What is qamChannelAnnexMode?

This read-only enumerated object reports which ITU-T J.83 annex standard, annexA(3), annexB(4), or annexC(5), a QAM channel is using, or unknown(1)/other(2). Admins check this to confirm the channel matches the modulation standard expected for its region and service type, since North American cable systems typically use Annex B while European systems use Annex A. For example, seeing annexB confirms this QAM channel is configured for the North American DOCSIS/digital video standard rather than the European Annex A standard.
