some mor einfo for the techs according to robin walker site this info is true.

Downstream Received Power: the DOCSIS specification requires cable modems to function correctly with downstream power levels in the range -15 dBmV to +15 dBmV: power readings at or close to those extremes are likely to be unacceptable. However, when connected to a real-life CATV network, a cable modem might be functional over a narrower range than this. Accordingly, cable ISPs will specify an even narrower target range when commissioning their network: this target range will differ according to ISP.
Target Commissioning Range Wider Working Range
NTL original areas
-2.5 dBmV to +2.5 dBmV
somewhat wider than that!
NTL ex-C&W areas
-6 dBmV to -3 dBmV
-12 dBmV to -3 dBmV

my reading is
Downstream Receive Power Level : -12.58 dBmv
