BT Infinity & FTTx Discussion

Are you moving the telephone number or telephone number & broadband?

I am only moving telephone. I was with BE but they wouldn't transfer to new house with me and said I had to migrate to sky. That def wasn't happening so as per what I've read on these forums I went with ZEN.

As ever I clicked the 'I have read the terms and conditions' button on the BT website when transferring house without actually reading them so more fool me
 
You can take it without BT line rental, but you still need the line. All line rental agreements that I'm aware of have a minimum term.

^^ these look about right within your 500m away from cabinet above 50 Meg as the chart show above

This kind of backs it up too:

Impressed with BT this week.

Recent storms gave my house a battering and my infinity was all over the place, ended down at 15mbps and flaky as hell even after allowing a few days to settle.

Email fault raised on Tuesday, phone call 10 mins later confirming looking into it, phone call next day to confirm engineer required and would today be convenient. Text to confirm.

BT Engineer arrived today, new cable installed from house to pole, rerouted master socket downstairs from attic, reset profile & DLM, blanked off unused sockets and would not leave until he was fully satisfied all was working without errors.

Infinity now back to full strength, phone line no longer has noise and all is well with the world all within the space of 3 days from point of raising fault.

Top work BT :)

That's amazing. It's great to hear the positive anecdotes, along with all the negative ones.

Surely this is a bit of a problem for Fibre services going forward? As speeds ramp up in the coming years, they're going to be constrained by the VDSL link over the crappy piece of copper wire from the box to your house?

Cable services obviously use co-ax for this link and, as they start ramping speeds up into the hundreds of megabits in the coming years, surely the Infinity services are going to run out of headroom?
 
Went out and found my cabinet today.

It's 110m away straight line, or following the roads, 150m.

:). I never even noticed it hidden away there, always thought I was connected to one further away.

Impacted speed (range b) is 62-80 on the estimate.

I would hope for the higher end being that close, unless they decided to route the cable in a dumb way.

Just gotta wait and see now :).

Maximum throughput of cable isn't everything. It still has STM, traffic shaping and more jitter than the average VDSL2 connect.
 
Virgin Media aren't competent enough to reliably provide a service running at 'hundreds of megabits' with the upload speeds to support this and have it usable at 8pm, so I wouldn't say there's any need for the VDSL providers to start panicking yet. Vectoring should go a long way to solve the degradation over distance problem, and when it's finally time to bite the bullet and run fibre at least they will have a more up to date map of where their services run.
 
If I'm getting approx 50Mbps 450m from the cab then you should be able to do a lot better.

Was watching the Everton and Chelsea game on BT Sport HD through the YouView box. During the game, Home Hub lost broadband connectivity 6 times. Came back quick enough though. I'm putting this down to the monitoring/tweaking that can occur in the first couple of days? Always had Virgin Media so this is all new to me. If the loss in connectivity continues I'll have to give them a call. It's never happened so far whilst browsing and other general useage

My cabinet has got to be at least 2-2.5km from the exchange.

Distance from the Exchange to the Cabinet doesn't matter - as that's the part of the connection that runs via Fibre.

Distance from the Cabinet to your Premises is the important bit - as that's the part that runs on the copper twisted pair.
Plus it's not just distance from Cabinet to Premises to worry about, as you might have rubbish quality cables, aluminium instead of copper, crosstalk from other customers, etc.

Guess I should have known I'd provoke that kind of response :rolleyes:

I never said cable wasn't without its problems or that one or the other technology was inherently superior in any particular way. I was just wondering how the FTTC infrastructure is going to cope with ever increasing speeds when it appears that the VDSL connection over the copper loop to the home is already becoming a limiting factor.
 
Well VM increase headline speeds by bonding DOCSIS channels together, which needs the bandwidth (frequency bands as opposed to Mbps) to actually exist on the infrastructure and the backhaul from the UBR to be there. Both that and vectoring are only delaying the inevitable (pulling fibre).

I guess if for whatever reason BT wanted to extend the life of copper they could use the second pair that exists in almost every incoming line and bond them together, but putting more copper into the ground to connect these together seems the wrong way to go.

Ahh, ok :D
At a rough guess about 700m from the cabinet to my house.
 
BT Wholesale Checker had made change again. Reduced on both download & upload speed from this morning.

Anyone else had noticed it? The left side is old one, the right side is made change today (new one)
