BT Infinity & FTTx Discussion

Well here's a graph of the interleaving, don't think its FTTC tho.

You can see the different levels of interleaving also.

Just found an example from my old FTTC connection.

That demonstrates a change in the level of interleaving perfectly. Note the thin red spike as the DLM initiates the change and then the step as the latency changes.
 
Thanks again.

Does heavy uploading/downloading affect the way DLM applies the setting? Or is it more to do with the SNR figures of the connection?
 
Another question, apologies if it's been answered before. I noticed yesterday, when the modem restarts, I was ending up with a new IP each time. Now I've not noted them down, so I don't know if they were in the same pool so to speak, but is this something to expect if I get any power cuts?

I used to Virgin where the IP was more often than not static.
 
IP's are very dynamic on BT, even if you disconnect for just a few seconds you will probably end up with a different IP, some are better than others (ping) at least for me anyway.
 
Guess I'll add No-IP DUC as a service then, as I connect in often when away from home. Shame really, static IP would really finish it off.

Can't say I've noticed a difference in ping, but as I said, it was all done quickly yesterday and I didn't have time to log anything.

I presume constant disconnects won't do me any favours with regards to interleaving coming off, so it can stay how it is for now.
 
Even if you disconnect your modem will still have a sync (unless you mean disconnecting your modem).

:D
 
Ah, of course. I forget that the WAN IP is assigned to the router, not the modem. So do a renew on my router and test with different IPs.
 
Do they take longer to upgrade a cab to fttp than they do fttc or something because my area is planned to be done by the end of march and after doing some checks on posts codes and comparing them with the spreadsheet, most of those those with fttc have been done where as my street with fttp hasn't?

Where can you check FTTP dates? Wasn't aware you could.

You mean the bt checker doesn't give fttp info?

I tried even more now and not a single fttp shows as even getting connected to infinity, yet they're set to be done on the same phase as the rest, the town has a lot of fttp postcodes so i don't get whats going on, though i can't be sure any are installed yet as some around here are fttc as well..
 
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?

Which checker exactly?
 
BT's claimed target is 25% FTTP coverage, but that seems unlikely at this rate. Almost 2 years into the rollout and there are strange situations like partially enabled cabinets with addresses 50 yards away unable to receive FTTC (bizarre wiring for the lose).

They can't even be bothered enabling FTTC in large tracts of surburban London never mind other cities, it's been pushed back repeatedly. I guess they want to leave it to Virgin Media\NTL...
