| docsIfExt2CmMscStatusTable OBJECT-TYPE This table extends the docsIfUpstreamChannelTable to report the CM MSC status. | 1.3.6.1.4.1.4491.2.1.5.1.2.1 | not-accessible | current | |
| docsIfExt2CmMscStatusEntry OBJECT-TYPE As an extension of docsIfUpstreamChannelTable this table has entries for each ifEntry with an ifType of docsCableUpstream(129) This entry is instantiated by the CM only if the CM is currently in SCDMA mode. | 1.3.6.1.4.1.4491.2.1.5.1.2.1.1 | not-accessible | current | |
| docsIfExt2CmMscStatusState OBJECT-TYPE 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. | 1.3.6.1.4.1.4491.2.1.5.1.2.1.1.1 | INTEGER {channelEnabled(1), channelDisabled(2), active(3), inactive(4), unknown(5)} | read-only | current |

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. | 1.3.6.1.4.1.4491.2.1.5.1.2.1.1.7 | INTEGER {noIUC2(1), limitedIUC2(2), freeIUC2(3)} | read-write | current |
