Description Defines the criteria that trigger a change in frequency hopping, modulation or channel width. Depending on the type of linecards, the criteria are slightly different: For the linecards that have no Hardware Based Spectrum Management capability like the uBR-MC1xC, change in modulation or frequency occurs in the following criteria: 1) Change from modulation profile 1 to modulation profile 2 would occur when CMTS detects the SNR that goes below the threshold and either corr FEC or uncorr FEC is above the threshold. In this case, snrBelowThres and either corrFecAboveThres or uncorrFecAboveThres bits will get set. 2) Change from modulation profile 2 to modulation profile 1 would occur when CMTS detects the SNR goes above the threshold+3 and both corr FEC and uncorr FEC are below the threshold. In this case, snrAboveThres and corrFecBelowThres and uncorrFecBelowThres bits will get set. 3) Change in frequency or frequency hopping would occur when CMTS detects no active modem on the link. In this case, noActiveModem bit will get set accordingly. For the linecards that have the Hardware Based Spectrum Management capability, change in frequency, modulation or channel width occurs in the following criteria: 1) when CMTS detects the SNR or CNR goes below the threshold and either corr FEC or uncorr FEC is above the threshold. In this case, either snrBelowThres or cnrBelowThres and either corrFecAboveThres or uncorrFecAboveThres bits will get set. 2) when CMTS detects the SNR or CNR goes above the threshold + 3 and both corr FEC and uncorr FEC are below the threshold. In this case, either snrAboveThres or cnrAboveThres and both corrFecBelowThres and uncorrFecBelowThres bits will get set. 3) when CMTS detects no active modem on the link or uncorr FEC is above ccsUpSpecMgmtFecUnCorrectThres2. In this case noActiveModem or uncorrFecAboveSecondThres bit will get set accordingly. Note: The order of frequency, modulation or channel width changes for the advanced spectrum management linecards will be determined based on the selection of the ccsUpSpecMgmtHopPriority.
