CoffeeBaron is right:

# DSLAM Make / Model ALCATEL FASTMUX_2000
User Label: Conklin
DV_AB

Unfortunately throughput speeds will not be any better until the upgrade.

your modem negotiated with DSLAM using ADSL2+ with line rate 7.5 Mbps Download, and 1 Mbps Upload. Line rate for ADSL2+ in theory is around 20 Mbps, and 2 Mbps UL, and achievable if your modem is just next to DSLAM. A few variables can impact line rate performance like distance between modem, and DSLAM, and environmental noises (electrical or magnetic).

Negotiated line rate is the max speed that can be achieved if the network (end to end, btw speed test client and server) got the resource to allow you to utilise it.

Hi, you will see in the original post the posters modem is reporting G.DMT which is ADSL1. Further the Conklins (which Chorus's notes report he is connected to) is a ADSL1 only DSLAM, so his speed is as fast as can be expected for ADSL1

Further Chorus ADSL2/2+ DSLAMs (ISAMs to be correct) are not configured to support annex M so max upload is roughly 1Mb/s, they are also configured with a 12dB noise margin target, thus rarely will achieve much over 18Mb/s.
