Stability is very important to me too but, I'm massively OCD about getting the best speeds possible unfortunately. The hard bit has been done as far as that's concerned, I just might need to spend some (more) money on the endpoint should the Draytek not suit. I've absolutely scoured the web and not been able to find any evidence that Tiscali were ever in my exchange. So fingers crossed the Draytek is the last router I'll be buying until my exchange and cabinet are fibre enabled.
And yes, as far as I'm concerned, I have the two important routers now (Broadcom and Infineon based) so should be able to optimise my line (again) as much as possible.

In terms of pure speed, using the TG585v7, downstream sync of 14295K, attenuation of 36.5dB and SNRM of 4.5dB with a single tone gap between 1889kHz and 1893kHz (tone 438) was achievable on my adsl2+ line but not sustainable.

Yet ~13500K sync, 37dB attenuation and 6dB SNRM is sustainable with up to 14 tone gaps in the higher frequencies and interleaved

That's reasonable and I wouldn't sacrifice stability for speed either, not that I've had any input into that thus far as I've not tweaked SNRM's at all.

As mentioned previously, I've taken a look under the hood of the Speedtouch TG585v8 and as stated by RouterStats, it does indeed have an Infineon CPU. As I can't embed thumbnail images, please follow the links below.

The Broadcom IC is the LAN controller.

So I've been migrated today and guess what? After spending £156 on the Draytek 2830n, I'm connected to a Broadcom MSAN. Guess my exchange was infiltrated by Tiscali before TalkTalk took over. Rubbish!

Anyway, I've put the Draytek up for sale (over on the AVForums if anyone is interested ) and have just bought a Billion BiPac 7800N.

I'm using my Netgear DG834Gv3 at the moment as oddly, it's providing the highest sync (10080kbps) currently, of all the routers I've tried. Attenuation is 39dB which is 2dB more than the same router was reporting on ADSL1 so, I expect the Billion to report 37.5dB from past experience. Hopefully my sync will come up too, and then I can start optimising the connection.
Oh and I asked to be on FastPath but, it looks as though I'm on an interleaved data stream. So that needs to be amended.

Paul

Now up to 10462kbps sync after a power cycle at 6am this morning. That gives a throughput of around 9Mbps which is 2Mbps more than I could achieve on my previous ADSL1 connection.

I'm aiming for a solid 10Mbps throughput. If I get there, I'll be happy.

Paul

Paul,

Sorry to hear that the Draytek router was unsuitable - best of luck with the Billion BiPac 7800N though

I find that I get the best downstream results with a pressac nte5 faceplate and a cat5 rj11 adsl (currently a 4.6 metre Belkin) cable also...

You win some, you lose some.

Have to admit, the filtered faceplates and decent RJ11 cables work wonders. My current set up includes an ADSLnation XTE2005 faceplate on the master socket in the loft (that is connected directly to the drop line (soldered) via cat5e cable, with a twisted pair per 'leg') and between that and the router is a 50cm Solwise shielded cat5e RJ11 cable. The house is 7 months old and the estate it's on is not much older. So as far as cabling and connectivity go (at least between the router and the cabinet), I couldn't do any more.

I've just got to nuture the connection now I guess and wait for the Billion to arrive. I think I'll do a power cycle again tomorrow morning and then leave it for when the new router arrives. Vivaciti advised that I should contact them 48hrs after migration to get the SNRM set to 6dB's. I'll make sure the set to FastPath at the same time.

Paul

After sending Matt at uno my router stats he advised against FastPath but it will be really interesting to hear how you get on with a 6dB downstream SNRM and FastPath on your Vivaciti SMPF broadcom connection - if you can get the downstream attenuation to 37dB, or just over, then you should achieve a downstream sync of 13Mbps which is what I get interleaved on 37dB and 6dB with uno SMPF/broadcom.

That's interesting. I went to FastPath on the ADSL1 service with great effect. It dropped my average latency to 13ms. That was on a line with a 6dB target SNR and was perfectly stable. Although ADSL2+ is of course more susceptible to noise, I don't think it will be an issue. We'll see I guess.
I used a Billion (7402GLX) previously and that gave an attenuation of 35.5dB when my Sky router showed it as 34dB. The router I'm currently using displayed the attenuation as 37dB on the ADSL1 service and shows it as 39dB on the new ADSL2+ service. So, I'd expect the new Billion to show it as 37.5dB.

I power cycled the router again this morning and it synced at 10926kbps. However, I've just logged into it remotely and it seems to have re-synced an hour or so ago to around 10290kbps. The SNR seems almost static at 6dB so, I hope it's just the router playing silly [censored] and maybe showing up a partial incompatibility with the MSAN.
Ah, I've just resynced it remotely and it's now connected at 11881kbps. That's more like it. I'll monitor it today and see how it behaves.

Paul

11881K @ 39dB and 6dB is excellent
