We'll a proper Openreach engineer 'Matt' has just left my house and after a faultless install, I'm now on 62/18....not bad for day 1 :)
And I was the first in the CAB: pair 801 8)
Goes away to push the limits..........

Great news :thumbs:
If possible (via an unlocked Huawei HG612 modem), I would suggest you grab your stats now.
Here's one way:-

& here's another:-

It will be interesting to see if they deteriorate (probably via increased crosstalk) as more & more users are connected.
How do your speeds compare with the pre-installation estimates?
-
I have the ECI modem installed today, but I'm up for this stats hack thingy. Need to do more reading to understand what I have to do.
Is it ok to use HG612 on this line? I'll have to nose ebay for one ;)
The BT site said estimated 62/20, PlusNet said the same......and I'm getting 62/18 still after a dozen speedtests!
-
The 62/20 estimate is the synch speed, not the throughput speeds (which you acquire doing a speedtest).
You will never, ever achieve 20Meg upstream on a speedtest. You will ony ever get between 80-97.6% (or 96.7% ??) of the synch speeds. Ergo, your upstream speedtest result of 18Meg fits just nicely. :)

You are a lucky boy. My time will come soon (hopefully in the next 4to5 weeks ::)
Can you give us your feedback now you are living in the fast lane!

Hullo! :)
I'm first on my cabinet too! I've got a fibre fatpipe all to myself! I left my beloved Be LLU because Murdoch scoffed it.
When the OR engineer called to say there would be an interruption in my service I hotfooted it to the cab to see what was inside that green box of mystery, he showed me the wires my interwebs go through.
I've got an ECI rev.B modem on an ECI cab about 250M from my house, stats 64/16 approx.
I'm keen to see the stats from the modem but the OR subbie said I shouldn't disconnect it for 10 days, I'm on day 3. I read a post from Bald_Eagle about the 10 day bedding-in period for VDSL being a fallacy, so would you say it'll be OK to flash my modem? I wanna make graphs baby!
Edit : it's on a BT Infinity 2 contract.

Hello MW. Welcome to the Kitz forum. :)
You say that you have been provided with an ECI modem. To make use of either Bald_Eagle1's or Eric's software packages you will need to obtain a Huawei HG612 modem and unlock it (by updating it with Asbokid's revised firmware).
When you come to swap over the modem, first power down the router, then power down the modem before disconnecting the latter from the telephone line. When powering down the devices, physically unplug each PSU from the mains sockets.
With the unlocked HG612 in-situ, reconnect it to the telephone line and then power it up. Once it has synchronised with the DSLAM, connect it to the router and then power up the latter.
If you follow that procedure, the DLM should not make any change to your line's service parameters.
-
The stabilisation process is not a 'fallacy' as such. The DLM (The bit that does the magic) captures the previous 24hrs data regarding error counts etc, and decides which bits to act upon. I've had a few circuits with high repeat reports, and historic data shows that it can take up to 10 days to stabilise the circuit, by way of dropping down through the 'bandings' a day at a time.
If there's no issue with your circuit, there should be no problem whatsoever in following BE's or Eric's graphing scripts. Welcome to super-fast broadband, and put a penny in the tin for our copper broadband cousins. ;) ;D
-
Hello both! Thank you for the warm welcome, kind advice and for the wealth of posts I've read of yours in the last 3 days.
I'll invest in an HG612 ASAP, I can't wait to gloat with graphs. :P

Hi MuttyWango, welcome to the forums.
I also defected from Be nearly 2 weeks ago
>> I hotfooted it to the cab to see what was inside that green box of mystery
heh, so did I, but unfortunately it was a sub-contractor that did my install, who arent allowed access to the FTTC cabs and he just did a 2 minute rewire in the PCP. He'd already locked up the cab by the time I got there.
>> I'm keen to see the stats from the modem but the OR subbie said I shouldn't disconnect it for 10 days.
I put my HG612 on the same day. I was going to wait because I didnt have the smoothest of installations (http://forum.kitz.co.uk/index.php/topic,12682.msg240029.html#msg240029) with 6 hours of downtime and I did several full resyncs and didnt want to push my luck with the DLM. :(
Anyhow I took B*cat, Colin, BS & BE's assurance that the DLM doesnt intervene until the next day... and at least that part was something that went right :)
My 10 days are up, but I can confirm that during this period Ive had a quite a few re-syncs, loss of syncs and even engineers just pulling the modem cables out, and touch wood Ive not been affected. It also looks at the error rates too. I have an intermittent line fault atm, but much of the time the line is stable and it produces little errors.
Follow B*cats advice, I always recommend powering down by unplugging the mains. This allows the modem to send a dying gasp signal down the phone line to the DSLAM so it knows its a power failure and not loss of sync through low SNR or errors. I also if possible wait 1/2 an hour before reconnecting, which helps the DLM know its a deliberate power down.

Kitz, just for clarification, only BT Power Engineers and BT PCR (Private Circuit repair) engineers are allowed to enter the Fibre Cab. If you had been fortunate enough to have had a fully-fledged BTOR engineer, as opposed to a Contractor, you would have only seen the same work going on at the original Cab. I think that's what MuttyWango would also have observed ?? Just the cross-connecting of wires in the original Cab ?? :)
-
That's right Black Sheep, just to clarify it was work in the PCP. I wanted to see the cable ducts and the board it connects to. The engineer explained to me that my copper wire pair were to be connected to the OR cabinet 50M away
I took a photo, there is a cable I'm curious about. On the right-hand side going down, looks like a black coax. Does anybody know what that is please?

To me it looks like the pipe linking the pressurised E-side cable to a pressure gauge . . . which would be located out of shot to the upper right of your photograph. Let's see what Black Sheep has to say. ;)

Thanks for the clarification, With the engineer mentioning "internet wires" and I therefore wondered if he may have showed MW the fttc cab as well as the old green pcp.

Bob-on as always B*Cat. It does appear to be the connection to our Cabinet mounted 'Pressure Transducers'. :)

YAY! Thank you so much for new knowledge gained.

Gentlemen,
I agree it is far more likely to be a pressurised gas tube rather than a coaxial cable as it has a brass-looking compression joint on the bottom loop.
Very sadly BT only use screened cables rarely and I'm not aware of any coaxial cables used within the PSTN infrastructure.
OTOH Virgin Media ONLY use co-axial cables for their broadband only distribution.
So instead of the delightful "free-form" illustration in the photograph above a single feeder radiates along every route with multiple services connected via a joint pod in each small cabinet.
No crossed pairs or other challenges are possible with this design, although VM do use a separate twisted pair for any telephone services provided.
The only other small cable which should appear at some stage is a 5 pr "Telemetry" cable which I understand has one pair connected for a dial-up electricity metering function.
Kind regards,
Walter

A great insight into VM's network by Walter, and just to add to it, the reason behind the vast differences is, VM's network has only been in place approx 20yrs, whereby they could take advantage of changes in technology and provide a fibre/co-ax hybrid network.
Also, the original owners (NYNEX), only cabled to densley populated areas, where they would see a quick return on their money. Something our very own Walter frowns upon when BT apply this same logic to VDSL roll-out. ;) :P
BT's network on the other hand, has been in place since Noah built the Ark. They also provide a telephone service to wherever you may live in the UK. :)
