Cable signal levels for all docsis cable modems require to be within the acceptable level for the modem operate properly.

Cable modem good power level.

Good downstream power levels are within 7 to 7 dbmv. 2010 04 10 08 58 44 mprogers technically low transmit levels upstream power can cause. Downstream power level rx this level is the downstream signal strength and can be plus or minus and shows the amount of signal received by the modem from the cable companies transmitter. However the power level on 1 of the upstream is 0.

Good upstream power levels are within 38 48 dbmv. To view the upstream and downstream power levels. It has 8 downstream and 4 upstream channels. Upstream power shows the level of the signal from the cable modem to the provider.
