0 db is exactly in the middle of the range from -15 to +15 that Docsis modems accept. The problem is, is it correct. I've heard that some modems report 0db meaning that they did not/cannot measure the downstream.
The upstream power level is very nearly at the max - you may experience problems.
upstream would look better if it were around 35 to 40db. the downstream looks good if its the true reading maybe you should check to see if its on the first split. chances are its not. and if it is then you probably need a new line to the house.
I agree that his receive is not 0, that is what some modems return. Also, his transmit is too high as 56 dbmv. I would like to see that down to at least 52. Could be a plant issue, too many splits in the house, a bad bi-directional amp, etc. That high on the transmit could lead to slow speeds due to upstream acks being choked out.
