Can turning up line signal cause poor line attenuation?

I asked BT to turn up the signal on the line when we first moved in as I was
running a rubbish 3com dial up modem and it kept dropping the
connection.Could that explain the 63dB attenuation I get and 15dB SNR?
Operational data report : near end (Downstream)
-----------------------------------------------
Attainable line rate : 2460 kbit/sec
Attainable Atm rate : 2176 kbit/sec
Used line rate : 744 kbit/sec
Fast used Atm rate : 576 kbit/sec
Interleaved used Atm rate : 0 kbits/sec
Rel. capacity occupation : 30
Noise Margin : 15 dB
Line attenuation : 63 dB
Output Power : 17 dBm

Near End line operational data :
RelCapacity downstream = 30 pct
NoiseMargin downstream = 15.5 dB
OutputPower upstream = 12.0 dBm
Attenuation downsteam = 63.5 dB
Operational Mode = 2

Far end line operational data
relCapacity upstream = 54 pct
noiseMargin upstream = 17.0 dB
outputPower downstream = 17.0 dBm
Attenuation upstream = 31.5 dB

I hope so - I cant get 1MB otherwise!

If your reading is 63dB you have no chance of getting 1MB adsl atm - you
only just make 512K if that (assuming the router's reading is accurate)

You currently need less than 45dB to get 1 or 2MB (unless/until BT
introduce RADSL for these higher speeds)

A +3dB increase in the reading actually means your line loss has doubled
as it uses a log scale..
