Upstream Channel Ranging Configuration
You can fine tune how cable modems adjust power levels during the ranging
process, as described in the following sections:
Power Offset Threshold (dB)
If power level offset reported by MAC chip is less than or equal to this
threshold value, then power level adjustment may be stopped. By default,
Power Offset Threshold is set at 8. Specified in 1/4 dB units.
You set the power offset threshold for an upstream channel by performing
the following tasks.
.
Task Command
1. Enable interface cable mode. interface cable <c/s/i>
2. Set the power offset threshold for
the current cable interface.
