this hopefully will help you
Unfortunately the HH4 doesn't offer any linestats via the interface other than connection speed.

You may be able to gain a little more information from the event log, such as the SNR Margin, shortly after a resync.
Event Log >
the latter stats will show your conenction speed down/up and also the noise margin down/up the normal down margin is about 6db and if higher than that suggests there is scope for faster speed
sorry can't be more specific as need more information from you
5. DSL uptime: 2 days, 19:53:066. Data Rate: 448 / 27527. Maximum Data Rate: 976 / 38688. Noise Margin: 17.0 / 13.19. Line Attenuation: 31.5 / 44.010. Signal Attenuation: 0.0 / 44.0
From the Event log WAN:
|14:58:37, 02 Sep.|
DSL Link Up: Down Rate=2752Kbps, Up Rate=448Kbps; SNR Margin Down=7.1dB, Up=17.0dB
|14:06:45, 29 Aug.||DSL Link Up: Down Rate=2880Kbps, Up Rate=448Kbps; SNR Margin Down=7.1dB, Up=16.0dB|
from what you have posted you are on adslmax with a connection speed of down 2.7mb and up 448kbps (448 is max for adslmax)
you could see if you can get upgraded to adsl2 which may give bit more down speed but should give about 100% increase in up speed
you can also upgraded to FTTC with estimated range 21/13mb down and 2/0.8mb up
