BT Infinity & FTTx Discussion

Is that a never ever getting FTTP? Not that it matters, I'd be happy with 80/20 tbh which it seems my cab/line can support from looking from the stats.
 
Watford isn't getting traditional FTTP as we know it.

However you might be able to get "FTTP on demand" when that's launched but there's all sorts of costings and so on to be worked out yet before it becomes commercially available.
 
Looks like fttp doesn't need a new cab, wish this was more common knowledge as i've been checking from time to time and getting a bit concerned, i guess there could still be delays but hopefully it's an easier job for bt to install, still no diea whether the checker is any use but it doesn't appear to be?

Installing FTTP is generally much harder/more expensive for BT than installing FTTC and takes longer.

You would think it would be the other way around, with fttc they have to install another cab, with fttp it's a few pipes to blow fibre down, i know that the last step with orders would take a bit longer to get the fibre hooked up to your house but the basic work looks easier with fttp.
 
So I was hoping for interleaving to be turned off, not up:

It's another aspect of the DLM. It will assign you an IP Profile based on how well the connection is performing.

When you see your level of interleaving increase there's also a chance your IP Profile may have been reduced. It doesn't always happen but there's a distinct possibility.
 
This is just an example taken from Google but it shows you where to find your IP Profile -

"IP Profile for your line is ....................."
 
Download speed achieved during the test was - 36 Mbps
For your connection, the acceptable range of speeds is 12 Mbps-38.72 Mbps .
Additional Information:
IP Profile for your line is - 38.72 Mbps

It's shifted again on the graph though.
 
It looks like interleaving was triggered by the second burst of packet loss.

The "second burst of packet loss" immediately prior to the increase in interleaving is actually the DLM implementing the changes.

There will be a brief loss of connection, indicated by the second spike, as the depth of interleaving is increased and the connection re-established.

If you look at any TBBQM where the level of interleaving changes, recorded as the "step" in the latency, then you'll always see a red spike immediately prior to the change.

Its actually a lot slower with FTTP, for one they are much more likely to encounter blocked ducts and you need to roll out fibre to each telegraph pole/distribution pole which means you only upgrade a few customers at a time (even without the end work), while you upgrade 100's of people at once with FTTC.

fwiw I think BT also found that the 'end part' for FTTP was also taking upto two days in their trials rather than the few hours they expected..

If they say the area should be active by the end of march can this be expected or will there likely be delays?

How well have FTTP installs gone for most towns?
