docsDrfDownstreamPhyDependenciesThe summary of the Downstream Interface
dependencies based on the constraints of
docsDrfGroupDependencyEntry.
A BIT position set to '1' indicates the PHY parameter
belongs to a dependency group.
A BIT position set to '0', indicates the PHY parameter
does not belong to a dependency group.
For Interfaces configured via DEPI this information is
reflected in the DEPI session as DEPI TSID group
dependencies.
If this object value is the zero-length string, it indicates
this interface is configurable via DEPI but no session is
currently active.ro Bits .1.3.6.1.4.1.4491.2.1.23.1.2.1.1 |

docsDrfDownstreamCapabFrequencyThe QAM channel frequency capabilities.
'qamDependency' BIT set to '1' indicates the QAM channel
frequency value has dependencies with other QAM channels
and an entry that includes this QAM channel is in
in docsDrfGroupDependencyTable for the PHY
parameter 'frequency'.
'adjacentChannel' BIT set to '1' indicates the QAM channel
frequencies in the dependency group (DEPI TSID group) are
adjacent and constrained in a frequency range based on
the number of QAM channels in the dependency group.
'adjacentChannelOrder' BIT set to '1' indicates the QAM
channel frequency adjacency is based in the QAM channel
sequence like entPhysicalParentRelPos in EntPhysicalTable
or other vendor sequence.
e.g., a dependency group of four QAM channels
with 'adjacentChannelOrder' BIT set to '1':
The 4th QAM channel in the sequence gets a frequency
assignment f + 1*bandwidth when the frequency value of
the 3rd QAM channel in the sequence is set to f.
Similarly the 1st QAM channel in the sequence gets a
frequency assignment of f - 2*bandwidth and the 2nd QAM
channels gets a frequency of f -1*bandwidth.
'adjacentChannel' 'adjacentChannelOrder' BITs may be set to
'1' when a dependency group includes the QAM channel
of this M-CMTS Downstream interface and the value of the
object docsDrfGroupDependencyType is
docsDrfPhyParamAdjacentValues.
'adjacentChannel' BIT may be set to '1' if
'qamDependency' BIT is set to '1'. The same way,

docsDrfGroupDependencyTableThis 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. SEQUENCE OF DocsDrfGroupDependencyEntry .1.3.6.1.4.1.4491.2.1.23.1.4 |
docsDrfGroupDependencyEntryA conceptual row of this table.
QAM channels are modeled as PhysicalClass 'port' from
the ENTITY-MIB.
An QAM channel can be represented as part of an entity
MIB containment tree as follows:
chassis(device)
.container(Slot)
.module(field-replaceable-module)
.module ( Physical RF spigot)
. port (QAM channel)
PhysicalClass 'stack' is left optional and not included
as a reference or examples for this table.
Based on the hardware capabilities the Agent will create
entries in this table including the entPhysicalEntry of
the close element to the root (e.g., up to 'chassis' or
'stack') including the PHY parameter of the dependency
as part of the entry index
The Aggregation is then defined as all the QAM channels
(entity PhysicalClass = 'port') below the tree as
indicated in entyPhysicalContainsTable.
Logical or software dependencies of the QAM channels PHY
parameters in addition to the hardware dependency entries
can be present and MUST persist during system
re-initialization. The storage realization of hardware
dependent entries are 'permanent' or 'readOnly'. The
storage realization of logical dependency entries is
'nonVolatile'.
PHY parameter dependencies that are logically defined may
be present in this table but its configuration is outside
of the scope of this MIB Module, including the definition
of simulated Physical components such backplane types or
modules accomplish its logical grouping.
PHY parameters with no Physical entities associated in
this table indicate no PHY dependencies for certain groups
of QAM channels.
Administrative changes to the
docsDrfGroupDependencyPhyParamLock are preserved in
non-volatile memory upon system re-initialization.
Note that any change in the system due to the
insertion or removal or components will reset to factory
default the entries associated with those components.
An entry in this table is reflected in the MIB object
docsIfMExtDownstreamTSIDGroupPhyParamFlag for individual
QAM channels.
A recursive method to find the PHY dependency group of an
QAM channel A, PHY parameter X is as follows:
The parent tree of QAM channel A is recursively calculated
by navigating entyPhysicalContainsTable from bottom to top
Pi(P1..Pn)
The list Mj (M1..Mn) of
docsDrfGroupDependencyPhysicalIndex represents the
values from this table with PHY parameter
docsDrfGroupDependencyPhyParam X and/or 'all'
The list Qi (Q1..n) is the list of matches of Mi in Pi
Qi with the lower position in the entyPhysicalContainsTable
is selected Qy and My is the group criteria selected.
All QAM channels Bi below My are candidates for inclusion
in the dependency group.
Each Bi is verified as A for its own BPi parent tree to
verify that in effect My is the lowest denominator in Mi
BPi intersection to become part of the Dependency Group
of A. DocsDrfGroupDependencyEntry .1.3.6.1.4.1.4491.2.1.23.1.4.1 |
docsDrfGroupDependencyPhyParamThis object represents the type of PHY parameter
that may have dependencies when setting an individual
object in the dependency group.
The value 'all' may be used as a wildcard to indicate
all PHY parameters have dependencies. The other
enumeration values are common QAM PHY parameters.
The opposite to 'all' is 'noDependencies', which indicates
no dependencies in PHY parameters, but is only used to
indicate no dependencies across all the device. Thus,
when used, 'noDependencies' is accompanied by
docsDrfGroupDependencyPhysicalIndex '0' as the only
entry in the table.
In this way it is clearly distinguished when a device
has dependencies instead of an empty table. Enumeration .1.3.6.1.4.1.4491.2.1.23.1.4.1.1 |
docsDrfGroupDependencyPhysicalIndexIndicates the physical element from where the PHY
parameter dependency for QAM channels is derived.

will belong to a dependency group of the specified PHY
parameter. PhysicalIndexOrZero .1.3.6.1.4.1.4491.2.1.23.1.4.1.2 |

PHY parameter being mapped.ro Unsigned32 .1.3.6.1.4.1.4491.2.1.23.1.4.1.3 |
docsDrfGroupDependencyTypeThe description of the type of dependency associated
with this dependency group.
Basic type of dependencies are docsDrfPhyParamSameValue,
docsDrfPhyParamAdjacentValues, docsDrfPhyParamFrequencyRange.
Vendors may define their own rules and policies to describe
their implementation dependency definitions such as
RowPointers to table entries or OBJECT-IDENTITY clauses.
If the dependency is not described this object is set to
zeroDotZero, although the dependency does exist.ro AutonomousType (SNMPv2-TC) .1.3.6.1.4.1.4491.2.1.23.1.4.1.4 |

of channels that can be transmitted from this blockro Unsigned32 .1.3.6.1.4.1.4491.2.1.23.1.5.1.2 |
docsDrfChannelBlockCfgNumberChannelsThe Number of QAM Channels N' to configure for the
QAM block.
This number corresponds to the number of channels that
are configured to be currently transmitted by the block.
The maximum number of channels per block follows the
consideration of maximum number of digital channels in
a headend described in the DRFI specification.
As a rule N' is valid if it is less than or equal to N.
In addition N minimal requirements consist of even
numbers and 1 (one QAM channel per Block Channel). Odd
number of QAM channels per Block Channel are optional
for implementation.

Error 'wrongValue'.rw Unsigned32 .1.3.6.1.4.1.4491.2.1.23.1.5.1.3 |
docsDrfChannelBlockMuteThe Mute control object for the Block Channel
A set to this object to 'true' is reflected in
ifOperStatus set to 'down' of the QAM channels
associated to the block Channel.
The opposite, a set to this object to 'false', is not
necessarily reflected as ifOperStatus set to 'up' since
other interface conditions might prevent such status.rw TruthValue (SNMPv2-TC) .1.3.6.1.4.1.4491.2.1.23.1.5.1.4 |
docsDrfChannelBlockTestTypeA set of in-service and out-of-service test modes.
The value 'noTest'(1) is the normal condition after
reinitialization where the QAM channels are expected in
operation.
'noTest'
It is also used to take out of testing mode
a QAM channel within the block.
In-service tests modes:
'offOthersNormal'
It is the condition where the QAM Channel indicated in
docsDrfChannelBlockTestIfIndex has its carrier
suppressed and the other channels in the
Block Channel are operational.
'allOff'
All QAM channel carriers in the channel block are
Suppressed.
'onOthersOff'
It is the condition where the QAM channel indicated in
docsDrfChannelBlockTestIfIndex is in operation
and the other QAM channels in the channel Block have
their carriers suppressed.
Out-of-service test modes:
'cwOnOthersOff'
It is the condition where the QAM channel indicated in
docsDrfChannelBlockTestIfIndex transmits a
continuous wave (CW) while the other QAM
channels in the channel Block have their carriers
suppressed.
'cwOnOthersNormal'
It is the condition where the QAM channel indicated
in docsDrfChannelBlockTestIfIndex transmits a
continuous wave (CW) while the other QAM channels in
the channel Block are operational.
