since attenuation is 11 and you are close to exhange SNR should go high. and you can easily get 20 mbps if you want. i think if you clear the problems with your line and if the exchange people increase the value of your speed from 12 mbps to 20 mbps then i think you can enjoy the full speed without any issue.
