My router told me my line attenuation is 54.0 dB and it can get an attainable rate of 943kbps only! Is this normal for an ADSL (not ADSL2+) connection.

My house alarm is not monitored and I have filter for every used phone outlet.
Is this normal for connection with attenutation of 54.0 dB? How can I reduce attenuation?
Also, shoud I move to ADSL2+ (e.g. Vodafone Red Zone) to get better better, or will it be quite useless given the bad attenuation I got?
Furthermore, is it normal to have different line attenuation for downlink vs uplink?
