I am on telecom ADSL2+, and I am getting low speeds for my Attenuation:

I was looking at the graph on this post: http://www.geekzone.co.nz/forums.asp?forumid=49&topicid=27834 and it looks like I should be getting 20 Mbits down? Any suggestions?
Thanks
Edit: More info:
- Your ISP and plan
Telecom 150GB + Phone line
- Type of connection (ADSL, ADSL2, VDSL)
ADSL2
- Your modem DSL stats (do not worry about posting Speedtest, we need sync rate, attenuation and noise margin)
Provided.
- Your general location (or street)
Mairehau, Christchurch
- If you are rural or urban
Urban
- If you know your connection is to an exchange, cabinet or conklin
Not sure.
- If your connection is to a ULL or wholesale service
Not sure.
- If you have done an isolation test as per the link above.
Yes, just did one, Attenuation remained the same for downstream, upstream increased to 40.
