Sorry.. I started to type this quite a while ago then got distracted by a phone call before managing to hit the "post" button.
Some of the stuff has already been covered (

>> Are you really on ADSL2+ via BT?
Thats one of the first things that entered my head.. afaik BTb arent using adsl2+ yet on any of the exchanges other than the 21C network ones (cardiff).
448 / 5,248 looks like Maxdsl to me therefore unless you are on adsl2+, modulation would be G.DMT. However it would appear that the HH sets G.992.1 annex A by default.
Ive also just noticed that the remote vendor ID is ALCB - which is Alcatel. If so then its probably an older type dslam rather than a MSAN. afaik the MSANs that BTw use are either Juniper or Marconi.
Dont quote me on that though because its not always a sure fire method of getting the dslam from the remote linecard chipset.
Yes the FEC errors are high.. but this can be fairly typical if your line has interleaving applied and means that Interleaving is correcting any errors on your line. Therefore would depend on how much data you have transfered since the router has been up.
As roseway says.. those stats are OK.. but could be better
I'd try testing from the socket behind the master phone socket to see if that improves anything.. in which case an NTE5 adsl filtered faceplate would be beneficial. [No longer applicable]
Im also not a big fan of the HH, since it doesnt quite seem to perform as well on max as some other routers, but a faceplate is a lot cheaper and also quite often one of the best performance fixes you can make.
