docsIf31RxChStatusPrimaryDsIndicatorThis attribute is used to identify the downstream channel
as primary, backup primary or non-primary. A value of
'primary(2)' indicates that OFDM channel is assigned to be the
CM's primary downstream channel. A value of 'backupPrimary(3)'

docsIf31CmtsCmRegStatusAssignedEmIdsThis attribute reports the set of CMTS-assigned EM-IDs for
this CM. This attribute is encoded as an array 16-bit binary
values with up to 3 elements. The broadcast EM-ID is not
included in the list.
If the EM-ID is unknown the CMTS returns a zero length string.
This object is applicable to DOCSIS 3.1 modems but not to prior
versions of DOCSIS modems. If the CM is a pre-DOCSIS 3.1 modem,

docsIf31CmtsCmRegStatusDsProfileIdListThis attribute is a variable length series of hexadecimal
octets where each series entry consists of the following fields
(encoded in the following order):
- The ifIndex (4 octets) of the OFDM channel where the
downstream Profile IDs are assigned.
- The number or count of Profile IDs (1 octet with valid values
of 1-4) assigned to the CM on that channel.
- The list of Profile IDs (1 octet each with valid values of
0-15) assigned to this CM on that channel. Profile ID 0 is
commonly referred to as Profile A. Likewise, Profile IDs 1,
2 and 3 are commonly referred to as Profiles B, C and D.
The CCAP encodes each OFDM channel in a CM's RCS as a separate
n-octet entry in the ProfileIdList.
Examples: a CM with a single OFDM channel (ifIndex 34) and
four assigned profiles (Profile IDs 0, 8, 9 and 10) would
have a ProfileIdList value of 0x00000022040008090A. A CM with a
2 OFDM channel bonding group each with two assigned profiles
(Profile IDs 0 and 15 on channel with ifIndex 34 and Profile IDs
0 and 14 on channel with ifIndex 35) would have a ProfileIdList
value of 0x0000002202000F0000002302000E).
Note: the CCAP must not include the transitional profile or
test profile in the ProfileIdList.
Note that octet string lengths greater than 18 are optional.
This object is applicable to DOCSIS 3.1 modems but not to prior
versions of DOCSIS modems. If the CM is a pre-DOCSIS 3.1 modem,
the CMTS returns a zero length octet string.ro OCTET STRING .1.3.6.1.4.1.4491.2.1.28.1.3.1.2 |
docsIf31CmtsCmRegStatusUsProfileIucListThis attribute is a variable length series of hexadecimal

of 1-2) assigned to this CM on that channel.
- The list of Data IUCs (1 octet each with valid values of
5, 6, 9-13) assigned to this CM on that channel.
The CCAP encodes each OFDMA channel in a CM's TCS as a separate
n-octet entry in the UsProfileIucList.
Examples: a CM with a single OFDMA channel (ifIndex 36) and two
assigned Data IUCs (5 and 6) would have a ProfileIdList value of
0x00000024020506. A CM with a 2 OFDMA channel bonding group each
with one assigned Data IUC (IUC 5 on channel with ifIndex 34 and
IUC 13 on channel with ifIndex 35) would have a UsProfileIucList
value of 0x00000022010500000023010D).
Note: the CCAP MUST NOT include transitional IUCs or test IUCs in
the UsProfileIucList.
Note that octet string lengths greater than 18 are optional.

docsIf31CmtsCmUsOfdmaChannelRxMerThresholdThis attribute specifies the percentile (such as 2nd percentile
or 5th percentile) of all active subcarriers in an OFDM channel
at which the ThresholdRxMerValue occurs. That is, (Percentile) %
of the subcarriers have RxMER <= ThresholdRxMerValue.rw Unsigned32 UNITS "percentile" .1.3.6.1.4.1.4491.2.1.28.1.4.1.4 |
docsIf31CmtsCmUsOfdmaChannelThresholdRxMerValueThis attribute is the RxMER value corresponding to the specified
docsIf31CmtsCmUsOfdmaChannelRxMerThreshold percentile value. The
CCAP sorts the subcarriers in ascending order of RxMER, resulting
in a post-sorting subcarrier index ranging from 1 to the number of
active subcarriers. If the percentile value corresponds to a non-
integer post-sorting subcarrier index, the post-sorting index is
truncated (floor function is applied); that is, the post-sorting
index is selected which is the greatest integer less than or equal
to the corresponding percentile value. For example, if there are
3677 active subcarriers and the 2nd percentile is specified, the
CCAP computes floor(3677*0.02) = 73. That is, the RxMER value of
the 73rd subcarrier in the sorted list is associated with the 2nd
percentile.

purposes another segment at the start of the IDFT output is
appended to the end of the IDFT output - the roll-off postfix
(RP). There are five possible values for the (RP), and the
choice depends on the bandwidth of the channel and the number
of exclusion bands within the channel. A larger RP provides
sharper edges in the spectrum of the OFDM signal; however,
there is a time vs. frequency trade-off. Larger RP values
reduce the efficiency of transmission in the time domain,
but because the spectral edges are sharper, more useful
subcarriers appear in the frequency domain. There is an
optimum value for the RP that maximizes capacity for a given
bandwidth and/or exclusion band scenario.ro DsOfdmRollOffPeriod UNITS "number of samples" .1.3.6.1.4.1.4491.2.1.28.1.9.1.9 |

docsIf31CmtsDsOfdmChanRollOffPeriodRoll off period maximizes channel capacity by sharpening the
edges of the spectrum of the OFDM signal. For windowing
purposes another segment at the start of the IDFT output is
appended to the end of the IDFT output - the roll-off postfix
(RP). There are five possible values for the (RP), and the
choice depends on the bandwidth of the channel and the number
of exclusion bands within the channel. A larger RP provides
sharper edges in the spectrum of the OFDM signal; however,
there is a time vs. frequency trade-off. Larger RP values
reduce the efficiency of transmission in the time domain,
but because the spectral edges are sharper, more useful
subcarriers appear in the frequency domain. There is an
optimum value for the RP that maximizes capacity for a given
bandwidth and/or exclusion band scenario.ro DsOfdmRollOffPeriod UNITS "number of samples" .1.3.6.1.4.1.4491.2.1.28.1.19.1.15 |

docsIf31CmtsUsOfdmaChanUtilizationThe calculated and truncated utilization for this physical
upstream channel, accurate as of the most recent
docsIfCmtsChannelUtilizationInterval.
The upstream channel utilization is expressed as a percentage
of minislots utilized on the physical channel, regardless of
burst type.
The utilization calculation can be expressed by the
following equation:
Utilization = MinislotsUtilized/MinislotsAllocated * 100%
For an Initial Maintenance region, the minislots for the
complete region are considered utilized if the CMTS received
an upstream burst within the region from any CM on the physical
channel. For contention REQ and REQ/DATA regions, the minislots
for a transmission opportunity within the region are considered
utilized if the CMTS received an upstream burst within the
opportunity from any CM on the physical channel. For all other
regions, utilized minislots are those in which the CMTS granted
bandwidth to any unicast SID on the physical channel.
For an upstream interface that has multiple logical upstream
channels enabled, the utilization index is a weighted sum of
utilization indices for the logical channels. The weight for
each utilization index is the percentage of upstream mini-slots
allocated for the corresponding logical channel.
Example:
If 75% of bandwidth is allocated to the first logical channel
and 25% to the second, and the utilization for each are 60 and 40,
respectively, the utilization for the upstream physical channel is
(60 * 0.75) + (40 * 0.25) = 55. This figure applies to the most
recent utilization interval.ro Unsigned32 .1.3.6.1.4.1.4491.2.1.28.1.23.1.22 |
