| Description | This table describes the rules that identify groups of
QAM channels with PHY parameters dependencies.
A PHY parameter dependency group means that a set to
a QAM channel parameter may affect the value of
other QAM Channels in the group.
TSID is a broadcast term borrowed by the M-CMTS
architecture to represent a unique identifier of QAM
channels in the M-CMTS architecture.
TSID Group is the DEPI concept of a set of QAM channels
with a PHY parameter dependency. This module refers to
TSID group as a PHY dependency Group.
This table uses the ENTITY-MIB physical component structure
to allows the managed system to describe the QAM channels'
PHY parameters dependencies. A management entity can use
the information from this table to generate the DEPI TSID
Groups.
Examples of PHY dependencies could be usage of adjacent
frequencies, or QAM channels of RF ports restricted, or
same interleaver value, modulation and J.83 Annex value.
Additional details and rules to describe the PHY parameter
dependency is indicated in
docsDrfGroupDependencyType.
Vendors may extend via other MIB modules the usage of
docsDrfGroupDependencyType. |
