1.3.6.1.4.1.4491.2.1.5 |
This MIB module contains the management objects that enhance
DOCSIS 2.0 feature set.
It includes SCDMA capability of limiting the number of codes
assigned to a CM over the total active codes, referred as
Maximum Scheduled Codes (MSC). |

docsIfExt2CmMscStatusState |
1.3.6.1.4.1.4491.2.1.5.1.2.1.1.1 |
Indicates the current state of the Maximum Scheduled Codes
feature on the CM.
channelEnabled(1) S-CDMA Maximum Scheduled Codes
is enabled in the UCD TLV-17.
channelDisabled(2) S-CDMA Maximum Scheduled Codes
is disabled in the UCD TLV-17 or a UCD has been
received that does not contain that TLV.
Active(3) The CM has received a Ranging Response that
contains a non-zero TLV-10
and therefore has MSC activated. This state
overrides the channelEnabled(1) state.
Inactive(4) The CM has received a Ranging Response that
does not contain TLV-10 or has it
set to 0. This state overrides the
channelEnabled(1) state.
Unknown(5) CM has not yet received a UCD to determine
if MSC is enabled or disabled on that channel. |

1.3.6.1.4.1.4491.2.1.5.1.2.1.1.2 |
Indicates the Power Shortfall at the CM, in units of
tenth dB.
The value is provided by the CM and is sent in the RNG-REQ
message. It is internally calculated in units of quarter
dB and is rounded upward for this MIB object to the nearest
tenth dB. A value of zero indicates that the CM has no power
shortfall. |

The value is provided by the CMTS through a TLV value in
the RNG-RSP message. Note that not all values from 4..128
are valid.
A value of zero when docsIfExt2CmMscStatusSate is active(3)
indicates there is no maximum scheduled codes value. This

The CM usage of IUC2 when MSC is enabled:
noIUC2(1): CM usage of IUC2 is prohibited
limitedIUC2(2): CM is allowed to use IUC2 as long as
the CM does not exceed MSC
freeIUC2(3): CM is allowed to use IUC2 without regard
for MSC.
With limitedIUC2(2), there may be cases where a CM cannot
ensure that the use of IUC2 would not exceed MSC. In these
cases, the CM MUST NOT use IUC2. |

feature can be enabled on individual logical channels on
the CMTS. The value false(2) indicates that the feature is
not in operations on the CMTS. Note that the MIB object
