I should have posted the stats before I changed so here's 3.3.5_RC2A (232201_A)

Code:
adsl status --------------------------- ATU-R Info (hw: annex A, f/w: annex A) ----------- Running Mode : G.DMT State : SHOWTIME DS Actual Rate : 8128000 bps US Actual Rate : 448000 bps DS Attainable Rate : 8128000 bps US Attainable Rate : 1240000 bps DS Path Mode : Fast US Path Mode : Fast DS Interleave Depth : 1 US Interleave Depth : 1 NE Current Attenuation : 21 dB Cur SNR Margin : 7 dB DS actual PSD : 19. 9 dB US actual PSD : 12. 6 dB ADSL Firmware Version : 232201_A -------------------------------- ATU-C Info --------------------------------- Far Current Attenuation : 10 dB Far SNR Margin : 27 dB CO ITU Version[0] : 00005453 CO ITU Version[1] : 00005443 DSLAM CHIPSET VENDOR : < TI >


and here's 3.3.5_RC5 (211011_A)
Code:
adsl status --------------------------- ATU-R Info (hw: annex A, f/w: annex A) ----------- Running Mode : G.DMT State : SHOWTIME DS Actual Rate : 8128000 bps US Actual Rate : 448000 bps DS Attainable Rate : 8128000 bps US Attainable Rate : 1244000 bps DS Path Mode : Fast US Path Mode : Fast DS Interleave Depth : 1 US Interleave Depth : 1 NE Current Attenuation : 23 dB Cur SNR Margin : 7 dB DS actual PSD : 19. 9 dB US actual PSD : 12. 7 dB ADSL Firmware Version : 211011_A -------------------------------- ATU-C Info --------------------------------- Far Current Attenuation : 11 dB Far SNR Margin : 27 dB CO ITU Version[0] : 00005453 CO ITU Version[1] : 00005443 DSLAM CHIPSET VENDOR : < TI >


As you can see, very little difference in the figures...

I've now thrown that firmware this morning before heading out for the day. See below for a set of comparative line stats (first and last on the same modem code).

Old line stats (3.3.4_RC10):

Happily passed 22Gb through the WAN interface whilst out today and all seems good so far...

Still find that rendering of the UI is slow to render (regardless of browser, much akin to waiting for images to load over 56kbit dial-up) - in particular the "Draytek" and the "vigor 2820 series" graphics. Maybe I need to load the .rst on ... unless that's expected behaviour.

A release note for 3.3.5_RC5 has appeared on the Polish FTP site. Here's an extract in relation to modem code...

File and Modem Code
(1)For Annex A Model,
"v2820_v335_211011_A" is used for modem code 211011(Standard).
“v2820_v335_232201_A.* is used for modem code 232201 (recommended for UK-SEG only).
"v2820_v335_211801_A" is used for modem code 211801.
"v2820_v335_2121501_A" is used for modem code 2121501.
"v2820_v335_2211201_A" is used for modem code 2211201.

Looks like the 232201 code is for the UK... (although it suggests going to the .tw site, I couldn't get on to it and couldn't find the file anyway)

The rest of the document makes interesting reading also...
