Setting the Upstream Power Level in Relative Mode
Issue the cable upstream power-level default command in Interface Configuration
mode to set the upstream input power level in relative mode, as shown below:
MOT(config-if)#cable upstream <NUM> power-level default <offset>
where:
NUM is the upstream port number.
offset is the number expressed in dB above or below the default input power level.
Example 1:
Issue the cable upstream power-level default command in Interface Configuration
mode to set the input power level for a 3.2 MHz channel in relative mode from +11
dBmV to +5 dBmV, as shown below:
MOT(config-if)#cable upstream 0 power-level default -60
The default input power level is reduced by 6 dBmV. The power level is now
+5 dBmV.
Example 2:
Issue the cable upstream power-level default command in Interface Configuration
mode to set the input power level for a 3.2 MHz channel in relative mode from +11
dBmV to 0 dBmV, as shown below:
MOT(config-if)#cable upstream 0 power-level default -110
The default input power level is reduced by 11 dBmV.
