As in this for NTL

Below is the recommended Downstream power levels for both NTL Platforms

Bromley (exCable & Wireless) Downstream power levels +6dB to +8 (QAM 64) +2.5 to +5.5 (QAM256)

Langley (NTL area) Downstream power levels -2.5dB to +2.5 (QAM 64) -1.5 to +2.5 (QAM256)

And this is for Telewest is Downstream power is -12dB to +12dB

This what you see in your config pages of your modem.
