I just re-synced the router following a stable evening and am now at 12056kbps. That's after a reduction in the router's target SNR of 3% (now at 52% of the ISP set target). So SNRM is at 3.4dB now. From previous experience, I'd expect that to drop and settle at around 2.7dB by tomorrow morning. I'll monitor the connection and check to make sure it's stable.

Throughout with the 11976kbps sync, using Speedtest.net was 10250kbps. I doubt that will change much with the new sync rate.

That's it as far as tweaking to get a higher sync rate I think. I'll just try and minimise the lowering of the SNRM in the evening now. Although, I'm not sure what else I can do to achieve that...

I can confirm that all TalkTalk lines, of which I have had experience, are connected to DSLAMs/MSANs with an Infineon chipset.

Bit late to this but my exchange has just been upgraded and the 2-Wire reports it as ITFN - I assume that is Infineon? I'm on a BT based service, so it isn't just TT who use Infineon based kit.

One other point. Didn't Texas Instruments sell their modem chip division to Infineon?

A BT based "What?" service? Broadband, phone or both?

I think he is referring to Broadband! It will have Huawei MASN (Multi-Service Access Node) using Infineon chipset at the BT exchange.

21CN introduced the concept of the Multi-Service Access Node (MSAN) http://en.wikipedia.org/wiki/Multi-Service_Access_Node

Broadband, as I would have thought was obvious from the post......

Thanks that's exactly what I wanted to know and confirms what I thought. Following the exchange upgrade, I'm on the same as you - BT WBC 21CN, although I'm currently using G-DMT.

Incidentally didn't Infineon buy up Texas Instruments chip division? This would mean the AR7 is currently manufactured by Infineon.

I believe there is some connection . . . but I can't find a reference to it, at the moment.

Infineon
Lantiq

Perhaps they didn't buy them up, possibly Infineon manufacture the AR7 under licence. Dunno.....

Yes! Texas Instruments inc. DSL chip manufacturing unit was bought by the German semiconductor manufacturer Infineon Technologies in 2007 and I did not realise Siemens is the parent company of Infineon.
