DOCSIS-CMTS-CM-US is an auxiliary schema that defines the CM's upstream channel status information. Revision History: 3.5.1-A.1 Initial version. 3.5.1-A.2 Revised version includes ECN OSSIv3.0-N-10.0914-3 and OSSIv3.0-N-10-0928-1 and published as I12. 3.5.1-A.3 Revised version includes ECN OSSIv3.0-N-10.0968-2 and published as I14. DOCSIS 3.0 Operations Support System Interface Specification CM-SP-OSSIv3.0-I14-110210, Annex N. Contains the first 50 characters of the ifName from the Interfaces Group MIB for the row entry corresponding to the CMTS upstream interface (ifType = 129). Contains the ifIndex for the upstream interface (described in CmtsCmUsChIfName). Contains the US channel id as defined in docsIf3MdChCfgChId. Contains the modulation type currently used by this upstream channel. unknown tdma atdma scdma tdmaAndAtdma Contains the receive power as perceived for the upstream channel. Contains Signal/Noise ratio as perceived for upstream data from the CM. Contains the microreflections received on this interface. Contains the equalization data for the CM. Contains the codewords received without error from the CM. Contains codewords received with correctable errors from the CM. Contains codewords received with uncorrectable errors from the CM. Contains the higher resolution timing offset to provide a finer granularity timing offset. Denotes if the CM upstream channel has been muted via CM-CTRL-REQ or CM-CTRL-RSP message exchange. Contains the ranging status of the CM other aborted retriesExceeded success continue
