Folks,
I've just taken over management of IT which includes a BT Business Broadband 2700HGV. I've been in telecomms since 1994, so have a good knowledge of voice systems and architecture.
Our place has a history of slow, non-operating broadband. At its best, we get 8MB down. This morning we were crawling at 0.5 - 1.5
A recent look at the hubs connectivity data revealed the following, shortly after a last-ditch reset in order to try and get us back on the air:-
DSL Unavailable Seconds: 178 178 0 0:23:37

Corrected Blocks: 65 65 45 0:00:00
Uncorrectable Blocks: 8 8 5 0:00:06
Does the prevalence of corrected/uncorrected blocks point to line issues? Likewise, the training errors?
Based on the product code, 4201-003003--008, this hub dates from late 2007, and there have been revisions of firmware since then.
Are BT happy to upgrade to the latest hub, particularly since their service is running over aluminium cables in the vicinity, and we've had far from perfect service for some time.
