ccsUpSpecMgmtTable
Table 3-10 lists the attributes in the ccsUpSpecMgmtTable table, which provides an entry describing
each frequency hop:
Table 3-10 ccsUpSpecMgmtEntry Attributes
Attribute Type Description
ccsUpSpecMgmtHopPriority INTEGER Specifies the priority of frequency,
modulation profile, and channel width in
determining corrective action for excessive
noise on the upstream (default is frequency,
modulation profile, and channel width)
ccsUpSpecMgmtSnrThres1 Integer32 Specifies the upper SNR threshold for
modulation profile 1 (5–35 dB, default of
25)
ccsUpSpecMgmtSnrThres2 Integer32 Specifies the upper SNR threshold for
modulation profile 2 (5–35 dB, default of
15, and must be lower than that specified
for ccsUpSpecMgmtSnrThres1)
ccsUpSpecMgmtFecCorrectThres1 Integer32 Specifies the FEC correctable error
threshold for modulation profile 1 (1–20%)
ccsUpSpecMgmtFecCorrectThres2 Integer32 Deprecated and no longer used
ccsUpSpecMgmtFecUnCorrectThres1 Integer32 Specifies the FEC uncorrectable error
threshold for modulation profile 1 (1–20%)
ccsUpSpecMgmtFecUnCorrectThres2 Integer32 Deprecated and no longer used
ccsUpSpecMgmtSnrPollPeriod Integer32 Deprecated and no longer used
ccsUpSpecMgmtHopCondition INTEGER Reports the condition that triggers a
frequency hop (SNR value or percentage of
modems going offline)
ccsUpSpecMgmtFromCenterFreq CCSFrequency Provides the center frequency (in KHz)
before the latest frequency hop
ccsUpSpecMgmtToCenterFreq CCSFrequency Provides the current center frequency (in
KHz) after the latest frequency hop
ccsUpSpecMgmtFromBandWidth CCSFrequency Provides the channel width (in KHz) before
the latest frequency hop
ccsUpSpecMgmtToBandWidth CCSFrequency Provides the current channel width (in
KHz) after the latest frequency hop
ccsUpSpecMgmtFromModProfile Integer32 Provides the modulation profile number
before the latest frequency hop
ccsUpSpecMgmtToModProfile Integer32 Provides the current modulation profile
number after the latest frequency hop
ccsUpSpecMgmtSNR Integer32 Provides the current SNR value (in dB) for
the upstream
