BT Infinity & FTTx Discussion

So on the DSLchecker stats for my cabinet just to see an estimate has it anywhere between 80-64. I'm guessing actual linespeed will be somewhere in between the two, hopefully closer to the high side?

Got about 3 months left on my contract. I have tried the forums, they kept asking for trace routes and then told me no fault on the line.

I read somewhere that OFCOM allow you to cancel your contact if the fault isn't fixed within 28 days. It's been 2 months. Should I be able to cancel or atleast ask for a massive discount? Currently pay over £40p/m for 80/20 yet I'm only getting 2/0.2!

You really need to ask for an FTTC3 visit. What does the router say? A throughout issue should be dealt with easily enough.

Infinity - Finally! But how?

Our area has been Infinity enabled for some time now but I've never been able to get it because my landline runs to a telegraph pole and then directly to the exchange without going via a cabinet.

Every now and then I use the Infinity checker and last night it told me that I could now get it.

So of course, I signed up straight away. I'll be going from roughly 4Mb ADSL to 75-80Mb fibre which is great news. The order has been accepted, I've got all the details and I've had an email from my current ISP confirming that my ADSL has been cancelled.

But I really wonder how this has been done. There's still no sign of a cabinet and as far as I'm aware, nothing has changed.

/edit - Moved this into the main Infinity thread

Very odd. They may have had enough interest that they're gonna build a cabinet

Feek · 15 Jul 2015 at 08:06

If that's the case then they've done it already as I've got an install date of less than three weeks. I've not noticed any new cabinets though.

The BT Wholesale checker even lists a cab number. Are the numbers printed on the outside? If so, I'll go for a walk around and try and find it.

There is a lot of work going into converting EO (Exchange Only) lines to have a PCP cabinet and thus provide FTTC. A few months back a pair of new cabinets (PCP + FTTC DSLAM) were built right outside my local exchange for some EO lines.

Terrier_Jimlad · 15 Jul 2015 at 09:23

Was on an EO line, a small cabinet was erected literally within the same grounds as the Exchange, just around the back of it - happily sat on 75Mb

Those FTTC figures are exactly the same as I see when I check my number. I'd be interested to see what you end up with.

Just set your expectation levels that the max speed will be what you see for 'Low' on the impacted line. Anything more is a bonus.

Stats for my line currently report:

High Low
FTTC Range A (Clean) 68.6 50.3
FTTC Range B (Impacted) 59.7 33

I say currently as when I signed up 18 months ago the above values were higher.

I originally signed up to Infinity 2. Max speed I got was 52 (BT Retail Website quoted 79). Over the next 2 months the speed degraded to 48. Eventually I downgraded to Infinity 1 and getting a solid 38.

ooo thats good news! Sitting on an Exchange only line at the moment so will be happy if my local exchange finally gets the cabinets

Following on from my previous posts, TalkTalk are suggesting that it's the BT fibre Modem that may be faulty here. Looking at the below trace route to Google, would you agree? Yes, I can see that the first 'hop' is the modem which shows a high response time but I'm questioning it as only manifests itself in the evenings from 16:00 to 00:00.

I'm assuming Talk Talk have asked you to use the equipment they supplied to carry out your testing?
Have you re-installed their equipment and run tests at the same two times of day to see if the fault is still there?

Princey · 15 Jul 2015 at 13:37

I have no other equipment to test, so just the BT supplied fibre modem and their own router. The modem has been power cycled but the issue remains. I may try a complete power down for 30 minutes.

They are currently sending out their 'Super Router' which combines both boxes for me to test.

Tephnos · 15 Jul 2015 at 13:43

Well, following on from the quoted post this is what I'm getting day 1:

It'll go down of course as DLM does its thing no doubt, how much by we'll see.

I don't think the first hop is the modem.

Princey · 15 Jul 2015 at 14:12

To be honest, neither do I, but it does have my WAN IP however. We'll see what the new modem brings, if not I think we can safely say it's congestion/load balancing at the exchange.

In my case, that figure is below the 'guaranteed' speed they've quoted me so it had better not be that low.

Three weeks to go, I'll report back.

Same with me mate. Was on an exchange only line. Work was done to move my line to a cabinet. I guess the same has happened with yours.

Tephnos · 15 Jul 2015 at 16:42

Playing the stats game now. In 5 hours with my connection running at full throttle at day 1, CRC errors have been 310, ES at 180. From what I read that's actually pretty good, and the important one, LOS is a solid 0.

Attenuation rose to 19.3 on the downlink when the service was turned on, and my Downlink SNR is 5.8, uplink is 7.1 - Never understood if these figures were good lower or not.

Signed up today for Infinity 1 + weekend calls, activation a fortnight from today, £10 pcm promo for BB and got phone reduced by paying 12 months up front. BTsport lite online thrown in for free.

Bye, bye, rip off Sky (randomly increased "copper" BB+phone from £24 to £33pcm recently, was originally with Be There until takeover, guess they price-matched for 12 months)!

Oh and the best bit is, there is ~£115 back via Topcashback (signed up today)!
