Billion 7800N and VDSL

From this e-tailer I found the following info:

The BiPAC 7800(N) series is compliant with worldwide ADSL standards, and supports download rates of up to 12/24Mbps using ADSL2/2+, 8Mbps using ADSL and an upload rate of up to 1Mbps.

Now given the FTTC upload speeds are around 4-9Mbps depending on various factors, does the above mean that the 7800N would limit the actual upload speed to 1Mbps?

No. Those figures are for ADSL, FTTC uses VDSL.

I can assure you that the 7800N handles profiles of ~39Mbps down and 10Mbps up without even working up a sweat

Thanks, that's a relief.

I've another question but not quite VDSL-related regarding the 7800N:

The integrated Annex M standard supports ADSL2/2+ for higher uploads by doubling the upload data rate

Now from BT's DSL checker site I read the following about my local exchange:

Our test also indicates that your line currently supports an estimated ADSL2+ broadband line speed of 6Mbps; typically the line speed would range between 3.5Mbps and 8.5Mbps. Our test also indicates that your line could support an estimated ADSL 2+ Annex-M broadband upstream line speed of 1Mbps and downstream line speed of 6Mbps; typically the downstream speed would range between 3.5Mbps and 8.5Mbps.

With my Thomson ADSL router, I get around 6Mbps d/l and 384Kbps u/l, but given the above info about Annex-M, could I achieve 1Mbps upload simply by switching to a 7800N?

You would need to ensure your line has an Annex M service, this will often cost extra and not all ISPs will offer it.

The 7800N does support Annex M though.

Ah okay, so not something for nothing then

Nope..

Even worse. At under 16Mbps download connection on Annex A, by switching to Annex M you would lose 2.5Mbps dowstream sync and gain very little upstream. Additionally, if you are above 7Mbps downstream sync on ADSL2+ you should already get more than 1Mbps upstream sync.
