if it's running at a 12db profile downstream (SNR goes in 3's) that is kind of high, standard is 6dB, or 9dB for longer lines. worst i've ever seen is 27dB.
Whats more important is the error rate. If you're seeing a high, increasing numbers of CRC or HEC (could be named errored seconds) then it looks as though you have a problem.
a high number of any errors in the upstream is considered bad news truth be told. could usually indicate a high resistance termination somewhere, which would need an openreach visit.
