canada | After a few requests i've posted the inside of the ST516.
I take no responsibility for anyone who attempts this. I did so nobody breaks it opening it the wrong way.
Push the power button in. Remove the two screws, DO NOT try to pry it open. simply PUSH the top part and it will slide back then open.
You dont have to open yours, I already opened mine for everyone who's curious to know what chip was inside.
By the way, upon careful inspection I am not to impressed. look in the back on the bottom right it looks as if someone sprayed desolder and didn't take it off properly. I guess that sticker made in china doesn't lie. |

2 edits | Ok, I am now back online, with the UK 6.1.4.6 version (found on this page).
Uff - followed Steve's instructions and links carefully, saved my configuration before the upgrade (Saves a TON of time reconfiguring it, just takes a sec.).
Having been burned by various motherboard BIOS upgrades in the past, it was a bit of a tense moment. All worked well, and I am happy and relieved.
First impressions :
- my Attenuation improved by 1 dB (now 51 dB).
- this version supports DMT, I wouldn't use a version that didn't. 
Thanks Steve for very detailed instructions and links.
Tilhas, thanks for showing us the internals of the modem. I think the 546 might have an extra chip on the underside of the circuit board, possibly the 4 port ethernet chip.
The bottom of the 546 gives off heat that really seem to indicate some busy IC there.
EDIT : DMT support and SNR tweaking seems to be flaky on this firmware - I might have to restore the original.

When you find your sweet spot in the SNR target. SAVE It. |

kudos:1 | said by TilhasBB:what do you mean by flaky? When you find your sweet spot in the SNR target. SAVE It. Yeah, I had my config saved, and reloaded it after each of the two firmware installs, etc. Using '10' in the register for SNR twek seems the best for me so far.
But the newer UK firmware behaved oddly with DMT - when I first opened the program, it would show the stats and graphs properly, just like in the 6.1.0.5 version (default that came with modem). Click on Refresh, and the graphs would no longer be there - data wouldn't come from the modem.
Tweaking SNR was not working well either, so I had to give up on my new Brit firmware.
** Try that one at your own risk, maybe it could work for others. **

canada | Thats what I did
I got them to put me on 5megabit even though their script refused me. I tried both alcatels K and G series and found G series was able to sync at a little higher rates. but both were rock stable.
