Because your connection comes off a Conklin DSLAM that has limited backhaul.

1. Profile is G.992.1 which is an ADSL1 standard (not ADSL2)
2. Noise margin seems high. On our LLU we use 12dB (standard) or 15dB (safe) - some profiles even go down to 6dB but usually only unbundled networks.
3. Attenuation is quite low
4. Not many errors, which is good

Is it an ADSL2 service/modem? How far are you from the cabinet/exchange?
Edit: answered above... Conkin... ADSL1 and IIRC, very safe (read slow) profiles...

More importantly the Conklin will only have one or if lucky two E1 uplinks, as your getting 1.6Mb/s downstream then my guess is just the one (ie E1 is 2Mb/s).

You are getting a 7Mbps ADSL1 connection so obviously the connection is not restricting you to 1.6M. Noise margin is high simply because ADSL1 cant go any faster, so that was a good thing back in the day.

As mentioned, Conklins are OLD and don't have the much backhaul at all, so you have to share that 2M speed with all other users in the area. It can handle up to 8M of backhaul across 60 users (I think) if fully expanded.

Do several speed tests at different times of day (peak and offpeak times), ask your ISP to get Chorus to investigate it as a throughput issue, and there might be a chance of getting more backhaul until the obsolete Conklin is finally upgraded to a modern system. I used to see even worse cases on a regular basis when Conklins were more common, and thats how Conklin throughput issues were usually solved. There might be a shortage of E1 ports available for backhaul these days, Chorus must be working on plans to switch over to new equipment as UFB starts freeing up the ADSL2 gear.
