DOCSIS 3.1 CCAP Operations Support System Interface Specification CCAP-OSSIv3.1-26.2430-1 This attribute is a unique index and is the identifier of the downstream profile associated with the OFDM downstream channel. The value of this key attribute is zero-based due to constraints of the definition of ProfileId. Information Model Mapping: CM-SP-CCAP-OSSIv3.1 DsOfdmProfileStats::ProfileId The DataIuc associated with this upstream OFDMA profile. Information Model Mapping: CM-SP-CCAP-OSSIv3.1 CmtsCmUsOfdmaProfileStatus::DataIuc This attribute is a series of octets where each entry consists of the following single octet fields (in order): Channel Id of the OFDM channel where the downstream Profile Ids are assigned, the number of Profile Ids assigned to the CM on that channel, and the Profile Ids assigned to this CM on that channel. The CCAP encodes each OFDM channel in a CM’s RCS as a separate n-octet entry in the DsProfileIdList. Examples: a CM with a single OFDM channel (channel id 34) and four assigned profiles (Profiles 0 (aka A), 8, 9 and 10) would have a ProfileIdList value of 0x22040008090a. A CM with a 2 OFDM channel bonding group each with two assigned profiles (Profiles 0 and 15 on channel 34 and Profiles 0 and 14 on channel 35) would have a DsProfileIdList value of 0x2202000f2302000e. Note: The CCAP does not include the transitional profile or test profile in the DsProfileIdList. Information Model Mapping: CM-SP-CCAP-OSSIv3.1 CmtsCmRegStatus::DsProfileIdList This attribute is a series of octets where each entry consists of the following single octet fields (in order): Channel Id of the OFDMA channel where the Profile IUCs are assigned, the number of Data IUCs assigned to this CM on that channel, and the Data IUCs 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 (channel id 36) and two assigned Data IUCs (5 and 6) would have a ProfileIdList value of 0x24020506. A CM with a 2 OFDMA channel bonding group each with one assigned Data IUC (IUC 5 on channel 34 and IUC 13 on channel 35) would have a UsProfileIucList value of 0x22010523010d. Note: The CCAP does not include transitional IUCs or test IUCs in the UsProfileIucList. Information Model Mapping: CM-SP-CCAP-OSSIv3.1 CmtsCmRegStatus::UsProfileIucList This attribute is the speed of the associated channel in bps if this were the only profile and 100% of data-capable subcarriers were utilized to transmit MAC frames in full codewords. ProfileFullChannelSpeed is intended to approximate the maximum speed available to the MAC layer; thus, this attribute subtracts out FEC and NCP overhead from the maximum theoretical speed. The maximum ProfileFullChannelSpeed for a given channel differs from the ifSpeed for the channel by the amount of this FEC and NCP overhead. bps Information Model Mapping: CM-SP-CCAP-OSSIv3.1 DsOfdmProfileStats::ProfileFullChannelSpeed The count of the total number of FEC codewords either received from the CM/CMs on this Profile/Data IUC for this upstream OFDMA channel. codewords Information Model Mapping: CM-SP-CCAP-OSSIv3.1 CmtsCmUsOfdmaProfileStatus::TotalCodewords The count of codewords received that failed the pre-decoding syndrome check, but passed the post-decoding syndrome check from the CM/CMs on this Profile/Data IUC for this upstream OFDMA channel. codewords Information Model Mapping: CM-SP-CCAP-OSSIv3.1 CmtsCmUsOfdmaProfileStatus::CorrectedCodewords This attribute represents the count of codewords that failed the post-decoding syndrome check received from the CM/CMs on this Profile/Data IUC for this upstream OFDMA channel. codewords Information Model Mapping: CM-SP-CCAP-OSSIv3.1 CmtsCmUsOfdmaProfileStatus::UnreliableCodewords This attribute is the count of unicast octets received by the CCAP on this profile. This value is the size of all unicast frames (including all MAC-layer framing) and CCF PMD overhead (segment headers and stuffing bytes) delivered from the PHY to the MAC - this includes user data, DOCSIS MAC Management Messages, etc. Discontinuities in the value of this counter can occur at reinitialization of the managed system, and at other times as indicated by the value of ProfileCounterDiscontinuityTime. bytes Information Model Mapping: CM-SP-CCAP-OSSIv3.1 UsOfdmaChannelDataIucStats::InOctets This attribute is the count of MAC-layer octets transmitted by the CCAP using this profile. This value is the size of all unicast, multicast or broadcast frames (including all MAC-layer framing) delivered from the MAC to the PHY - this includes user data, DOCSIS MAC Management Messages, etc. Discontinuities in the value of this counter can occur at reinitialization of the managed system, and at other times as indicated by the value of ProfileCounterDiscontinuityTime. bytes Information Model Mapping: CM-SP-CCAP-OSSIv3.1 DsOfdmProfileStats::ProfileOutOctets This attribute is the count of MAC-layer Unicast octets transmitted by the CCAP using this profile. This value is the size of all unicast frames (including all MAC-layer framing) delivered from the MAC to the PHY - this includes user data, DOCSIS MAC Management Messages, etc. Discontinuities in the value of this counter can occur at reinitialization of the managed system, and at other times as indicated by the value of ProfileCounterDiscontinuityTime. bytes Information Model Mapping: CM-SP-CCAP-OSSIv3.1 DsOfdmProfileStats::ProfileOutUnicastOctets This attribute is the count of multicast and broadcast octets transmitted by the CCAP using this profile. This value is the size of all frames (including all MAC-layer framing) delivered from the MAC to the PHY and addressed to a multicast MAC address - this includes user data, DOCSIS MAC Management Messages, etc. Discontinuities in the value of this counter can occur at reinitialization of the managed system, and at other times as indicated by the value of ProfileCounterDiscontinuityTime. bytes Information Model Mapping: CM-SP-CCAP-OSSIv3.1 DsOfdmProfileStats::ProfileOutMulticastOctets This attribute is the count of frames transmitted by the CCAP using this profile. This value is the count of all unicast, multicast or broadcast frames delivered from the MAC to the PHY - this includes user data, DOCSIS MAC Management Messages, etc. Discontinuities in the value of this counter can occur at reinitialization of the managed system, and at other times as indicated by the value of ProfileCounterDiscontinuityTime. frames Information Model Mapping: CM-SP-CCAP-OSSIv3.1 DsOfdmProfileStats::ProfileOutFrames This attribute is the count of unicast frames transmitted by the CCAP using this profile. This value is the count of all frames delivered from the MAC to the PHY and addressed to a unicast MAC address - this includes user data, DOCSIS MAC Management Messages, etc. Discontinuities in the value of this counter can occur at reinitialization of the managed system, and at other times as indicated by the value of ProfileCounterDiscontinuityTime. frames Information Model Mapping: CM-SP-CCAP-OSSIv3.1 DsOfdmProfileStats::ProfileOutUnicastFrames This attribute is the count of multicast frames transmitted by the CCAP using this profile. This value is the count of all frames delivered from the MAC to the PHY and addressed to a multicast MAC address - this includes user data, DOCSIS MAC Management Messages, etc., but excludes frames sent to a broadcast address. Discontinuities in the value of this counter can occur at reinitialization of the managed system, and at other times as indicated by the value of ProfileCounterDiscontinuityTime. frames Information Model Mapping: CM-SP-CCAP-OSSIv3.1 DsOfdmProfileStats::ProfileOutMulticastFrames This attribute is the value of sysUpTime on the most recent occasion at which any one or more of this entry's counters suffered a discontinuity. If no such discontinuities have occurred since the last re-initialization of the local management subsystem, then this attribute contains a zero value. secs Information Model Mapping: CM-SP-CCAP-OSSIv3.1 DsOfdmProfileStats::ProfileCounterDiscontinuityTime
