ADSL2+ vs ADSL2+ Annex M?

Sometimes, I've been checking properties to find out what kind of fibre broadband speeds they're getting (using addresses from google maps, only for informative purposes (trying to find a house that might give me better speeds as I'm moving soon! :P)) and I've noticed something strange.

 

On certain exchanges with ADSL2+ enabled, I have sometimes noticed a row for "ADSL2+ Annex M". What exactly is the difference between these packages? They report the exact same information, although the row for "Annex M" reports a upstrream "Up to 1.5" rate for which ADSL2+ doesn't report (it's just dashed lines).

 

Or is it just a bug and the "Annex M" package isn't really a package, but just the technology for ADSL2+? Thanks! 😄

annex m gives a faster upspeed to adsl2 but is not available to residential customers and it was suggested BT no longer do annex m for business

So it's basically a useless package they're not offering anymore? Considering the speeds of Annex M seem to be just the same as normal ADSL2, it seems redundant in any case 😛

no annex M gave a faster upload speed so in that respect was better than adsl2

Oh ok. But as you said... they don't offer the package anymore, so confused as to why they're still listing it on dslchecker.bt.com (much less on residential properties which is not available to them O.o)

I am aware. However, I thought they'd at least make sure that obvious "buisness only" packages don't show up on residential properties. o.O

Ah, makes sense. I've seen some Annex M providers when I searched, so I guess they just report that information for those Annex M providers. It's kinda useless, unless you need a dropped download speed to boost your upload. Frankly, I'd just take fibre if it's available 😛
