How can this be????

Hi All

Using the TBB map for my postcode area the typical speeds around my location were no surprise i.e. approx 2Mbps or lower where the location was even further from the exchange.

Right now the oddity, I noted a while ago that TalkTalk were a LLU provider at the exchange and just recently there are some 'logged' speed measurements on the TBB map but the DL speed shown is way over what one would expect compared to the other ISPs. The difference in one instance on the map is that TalkTalk gives a DL of over 3.5Mbps but all the other 4 tests show < 2Mbps

Hence the question just how are TalkTalk able to get such speeds compared to BTW connected users??? Afteral I thought they would be using the same copper just different "kit" at the exchange?

TIA for the insight

ADSL2/2+ generally gives you a 1Mb increase.

That's whats most users on TalkTalk will be using.

Ah! the devil in the details

A pity TT has such a mixed/poor service as I would not just switch in the hope of increased speed if the support & service was inadequate

No, ADSL2+ generally gives a decrease on long lines, because it generally ups your attenuation by 3 dB; ASL2 makes no difference,

Another main reason is no BRAS profile on TalkTalk, so you get close to the speed you sync at.

Yeap it will be due to the [censored] BT BRAS rates, TalkTalk do not have the same banding system as BT and you get the full throughput for the sync.

Thanks guys for the added insight.

IMO another "indicator" that BRAS is a not customer friendly because if it really was to the benefit why do the likes of TT (and other LLU providers?) find its lack OK ???

I really wish BT would scrap it.

Ah! the devil in the details wink

HHAHA

they provide a monopoly service and aren't having to route users data back to individual ISPs. They have a "collection point" if you like in the exchange, whereas BT are routing hundreds of individual paths back to multiple service providers via dimensioned paths.
