Well Thomas, you're not stuck in limbo any more then
Absolutely not!
The engineer seemed to be quite helpul & obliging & hopefully your various line issues have now been permanently fixed.
I'm not sure about the bell wire though. Someone else may advise you to remove that???
What surprises me and I think surprised him, is that we never heard any crackling on the line (symptomatic of an HR fault- the broken wire in the cab).
It should take around 10 days or so for your speeds to stabilise.
Are you happy with the current speeds? They are a lot higher that your "meaningless" estimated speeds.
I guess for a line of my length it's probably as good as it's going to get- I count myself lucky that we are able to get FTTC. I do hope that it keeps up at these speeds, though.
I'm really glad that you managed to take a photo of the JDSU showing the estimated line length. None of my visiting engineers have shown that display to me. More than one visiting engineer told me that the JDSU could not display that sort of detail when I asked them for it
I will be using your photo as evidence (if you have no objection) when the next engineer vists me, hopefully during this week.
I believe that line length is estimated via the JDSU mainly based upon on the attenuation figure, but more knowledgeable people than I aren't really quite sure for VDSL2 purposes. It may well take other factors such as SNR levels into account.
By all means show them the picture- perhaps you'll teach the engineers something!
Due to your actual or estimated distance from the cabinet, it is very unlikely that 40 Mb would be delivered to your home.
Others with guesstimated line lengths of around 650m & a JDSU attenuation value of around 19dB or so have been achieving download speeds of around 37Mb, more or less the full whack available, less a bit for overheads.
The IP Profile & download speeds as shown in the BT speed tester & the engineer's JDSU apparently always appears a bit more pessimistic than actual download speeds as shown by other speed testers such as speedtest.net.
If the line length is 900m or thereabouts, I guess these kinds of speeds make sense.
All I would suggest is that you regularly monitor your download speeds as reported by speedtest.net for consistency, along with regular BT speed test results (save the screenshots).
If nothing else, you will have a good record of your connection's capabilities if your speeds should start to plummet outside the 10 day training period. Your speeds may well even increase over the next few days.
I hope you're right- I've only had one disconnection so far- that was at 2.30 in the morning. Not entirely sure why it happened then (we were all fast asleep).
EDIT: Just for curiosity, which version of the modem has BT supplied for you?
It should be displayed on a sticker underneath the modem, the firmware version ending in SP06 or SP10, & the hardware version may have a 2V or 2B sticker, also underneath.
Also please see the PM that I sent to you
The modem is 2B HW, with SP10 SW.
I'll reply to your PM after this
Thomas
