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.

docsIfExt2CmMscStatusPowerShortfall 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.

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.

docsIfExt2CmtsMscGlobalEnable 1.3.6.1.4.1.4491.2.1.5.1.3.1
Indicates the global state of the Maximum Scheduled Code feature on the CMTS. The value true(1) indicates that this 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 docsIfExt2CmtsUpChannelMscState exists to enable or disable Maximum Scheduled Codes on a per logical channel basis.
