Thomson 585v7 or 2Wire 2700

[#1]

Hi
Currently running the Thomson 585v7 and syncing a 2.5mbit with a fairly long line (4.1km, 56dB downstream attenuation). I've managed to get hold of a 2wire 2700 I could use, was just wondering what peoples opinions/experiences are with them?
Kitz reckons my theoretical maximum sync rate would be 3712kbps!
Thanks

[#2]

I have both.  The 2wire might sync a bit higher, but it isn't guaranteed to be stable.  Also, in my limited experience, the 2wire has a chance of messing up your target snr margin from 6dB to 9dB which will lower your overall sync.

Doesn't the 2700 have a default SNR of 9dB?

[#4]

Nope!. Ones with BT firmware will allow a target SNR down to 6db. Ones with the Singtel f/w will only go down to a minimum of 8db.

Interesting. Tempted to give it a go, but always wary of changing routers/resyncing too much for testing hence the original post

I have both devices and the 2Wire wins hands down for me. It synchronises at a higher rate, retrains quicker when the sync is lost, and my home network sharing/media extenders work flawlessly (they often play silly [Censored] when I'm using the Thomson and can't see each other). The only problem I have with the 2Wire is the fact that it sometimes throws a wobbly when there's a lot of torrent traffic passing through it (this isn't too regular an occurrence though and it's certainly more than capable of 'doing' torrents).
I'm using firmware version 5.29.107.19 and my downstream SNR is 6db (see attached screengrab).
Some good info on the 2Wire here.

Good to know Bob., thanks. This is using the BT 6.1 firmware, but does't seem a massive issue to get my pn details into it.
To throw another one into the mix, I also have a ST510v6 here which can be tweaked with DMT Tool.
Choices choices!!

Any particular settings you had to setup for it to sync? Just plugged it in and left for 5 minutes or so and it was unable to sync. Was getting alot of these in the event log:
INF  P0000-00-00T00:02:45  hurl  err=0 name=PHY_NONE clear
INF P0000-00-00T00:02:57 hurl err=0 name=PHY_NONE detect

Nope, it should synch with those settings.
Don't take this the wrong way, but you have got the line plugged into the correct socket on the 2700, the DSL one NOT the one marked Phone Lines ( they will both take an RJ11 IIRC ).
Assuming thats ok , any chance of trying it on someone else's DSL line to check that the 2700 is OK. Even with your PlusNet username/password it should at least synch ( Broadband(DSL) Led Solid green ) on any line with DSL active. 

[#10]

Yea, def plugged into the DSL socket and yes they do both take RJ11, the 2wire comes with a RJ11 -> 2x bt socket dongle too.
The router should sync on anyl supported dsl line, so I'm surprised I didn't even get sync. I'll whack it on one of our spare adsl lines tomorrow at work.
Sync speed has dropped a bit from trying it tho, happy days!

I didn't have the BT branded version.  I had some SBC branded version courtesy of digidave.
The target snrm started off at 6... which is what the other modem left it at... and gave a lovely high sync, but overnight jumped to 9.  I've never been able to get it back down to 6 in the last 6 months

@gyre, That's a bit unlucky. The 2700's do tend to synch a bit higher ( which is normally good ) but I guess in your case that led to an increased error rate which caused the DLM to raise the target SNR and thus lower the synch again. Unfortunately it seems that the DLM is VERY reluctant to lower the target again, you seem to need to get VERY low error rates for some considerable time for it to lower it again. My experience with 2700's is pretty good however. My home line has an attenuation of around 30db, with my original Belkin router it would try and synch at ~7000k  but drop out a couple of times and eventually settle at about 6500k, the 2700 holds 8128k rock solid with a margin of ~8db ( 6db target ). I've used a couple for our home workers who have long rural lines and they are much faster ( and stable ) than their previous routers. Even got one in the office ( and a spare ), that one synchs at 22Mbps ( on a C&W LLU ) , again rock solid for months on end...

Try again, I'd pasted the URL twice.

@bob, i'll give the DLM 15 days of no tinkering, then I'm after BT blood
@bob, you could always turn the 2700 into just a modem, and put a real router in front of it that would survive torrents.
