Had no nettage this morning, and although Im now back up, Im seeing some weird things (changing attenuation) and not being able to get Annex_M upstream... and fluctuating sync speeds all over the shop.
.....anyhow that aside... look what kitzy has just spied being installed about 1/2 mile away.

Thank you very much Mr BToR Man for letting me take some pics with my phone :)

What ho! An ECI DSLAM has come your way. (Just don't tell Walter otherwise he'll be up there, quicker than a ferret up a drainpipe, to take a look.) ;D
-
Very Nice. The ECI boxes seem to be a lot more stable to boot!
-
Hey! don't you go round kicking the street furniture Azzaka. ;D
-
I wonder if they have been specially coated to resist corrosion as a result of the inevitable anointment with doggy fluid? :angel:

>> An ECI DSLAM has come your way.
Indeedy it has :)
I'd said to someone else 2 weeks ago that Id seen a man and a BT van putting in what looked like blown fibre down the main road, but unfortunately due to time and the fact I had to be elsewhere meant I couldnt stop and have a proper look.
But today I happened to notice a BToR van parked up with the traditional red and white tent, so I pulled over to have a nosey and see what was happening. The Guy was really nice, unfortunately I had to be elsewhere this afty so didnt have chance to take him a bacon butty.
The location of the cabs though lead me with some doubt as to what speed Id get with FTTC - , the cabs arent so near :( :(
Edit.
oh oooh oh ... just checked the adsl checker.. a couple of weeks ago it said 2013... today it says RFS date 31.12.12

Hmmm 1/2 mile away you say.
You could do worse than spend a minute or two reading :-

I know BE, thats one of the things that worries me about FTTC having seen your sad tale... I could end up shelling out £'s for not that much more speed than Im getting atm :(
Whilst I appreciate that it will help many who live further away from the exchange, my distance from the cab causes some trepidation :(
The copper run is certainly not going to be much shorter than it is now.
-
o0ooooo we have changes today... the BTw infintity checker is now telling me for the first time that FTTC is available.
Another number on the same exchange shows as not available.
-
Has it suggested a speed estimate?
-
The method I tried when I got conflicting reports was to go through the sign up procedure without signing up.
That is stop short of signing up for the service.
If it is not available you will be informed of that fact and asked to register your interest.
You can always just close the browser at any point.
Unless you want to sign up that is. :)
-
Kitz will sign up for it. She has to, she wont be able to stop her curiosity. Its instinct.
If she's only 0.5Km away from the cab, she'll notice a great improvement as well, according to the stats we have. She wont be dissuaded by the evil nay-sayers, and will probably end up buying an i-Mac to compliment her new super-fast service. ;) ;D
-
>> Its instinct.
It is, but I also have to consider a few things - the biggie being financial.
Other factors:-
Im very happy with my existing 24/2.6 connection.
Ive absolutely no idea how much bandwidth I use as most of it is streaming (i-player)
No idea which cab Im connected to (1 of 2), but regardless which one, most of the distance will still be copper... if its the cab I suspect.. the run will still be mostly copper and very little fibre.
Concerned what effect my very slowly degrading line will have on speeds on fttc.
Put it this way.. I dont wanna fork out more £ and risk not having much better speeds than I do now.
>> The method I tried when I got conflicting reports was to go through the sign up procedure without signing up.
Thanks SS I may give that a shot.

None of the run from the Cab will be Fibre, Kitz, whatever Cab you're connected to. It's only 'Fibre to the Cab', anything beyond is still Cu/Al.
Regarding price, I believe its not that much more than your ADSL package for the 40/2 or 40/10 product, but cant quote actuals, its just the feedback the EU's give me.
-
>> None of the run from the Cab will be Fibre, Kitz, whatever Cab you're connected to.
Yep BS, Im aware of that - sorry if I didnt explain well :/ I think what Im trying to say that the length of fibre between the exchange and cabs are going to be short runs.

I have to say, I did think it a bit odd that you wouldn't be aware of exactly what FTTC entails. It's just it read like you were under the impression part of the D-side run would utilise Fibre.
Apologies for mis-reading your statement.
-
hah... its ok... it just gets even more confusing, because Ive just street walked google maps.
Theres actually 3 cabs that I could viably be connected to. Imagine a triangle and pick a corner.
Cab 'no 3' is only 200m from cab 2, but still a possibility. Phone lines are UG so that doesnt help me much either. :/
-
I'm sure if you told a friendly CP representative (I'm thinking about Azzaka (http://forum.kitz.co.uk/index.php?action=profile;u=702)) your telephone number and postcode he could look up which cabinet in the Beatie supplied dbase. :-\
-
>> I'm sure if you told a friendly CP representative
Thank you B*cat for the suggestion... Ive just found out that theres a 4th cab within the triangle that I never was aware of nor have I ever seen. ??? so I think a little walk tomorrow when its daylight will be on the agenda to try and find something that I must have walked past many many times yet never seen. A trip to spec-savers may also be in order :D

Oh! found it. Oh my. 3 cabs all within 200m of each other.
-
If your with BT i think the price is the same for FTTC as it is for ADSL.
At least it was for me to switch from Total Broadband option 3 to go on Infinity option 2
-

Ah, but how far from each cab to the home is the important matter.
-
Exactly BE.
About 8 yrs ago I managed to get my actual line length from the BT number (which you can no longer do) and I cant find where I saved the info to now but I think I remember it right. Then subtracting the walking distance today between exchange and cab.
I just wish there was some more detailed linear info somewhere for vdsl speeds.
*Thank you very much to the kind person who has confirmed details of my cab and line.
-

I have no idea on what calculations are based & how accurate it is across the board, but the VDSL2 17MHz calculator in the DSL Tools section at this site doesn't look too far adrift for my own connection:-

What sort of copper distances are you looking at for your connection?
-
Supposing Kitz was to borrow a TDR and measure the (electrical) length of the pair from her NTE5/A to the exchange MSAN? That would give us a far more accurate baseline datum point, from which various guesstimates could be made.
I wonder if Mrs Eagle would fancy a day-trip to Blackpool? It is certainly within distance of the Eagle's nest, situated within the Devil Worshippers' catchment area. >:D
-
Thank you very much everyone for your replies...
I now have a pretty good idea of my line length from the cab and based on that info I should be ok to get 40Mbps, probably a bit more on 80/20 :)
-

Ah, now you have just moved the goalposts :o
In metres, are you willing to divulge the "likely" distance?
-
@ Kitz & BS,
Another thing to be aware of, particularly as you have an ECI 256, is that there is a good chance that your initial speed will degrade over time due to power cut-back to reduce cross talk on competing twisted pairs.
To give BT Wholesale their due, they do mention that on their estimator.
I have an example of a service actually skipping two intermediate PCPs with a map measured distance of about 1 Km. The BT W estimate, which is still available, says about 35.7 Kbps down. The initial sync speed was just under 30 Mbps but that has now dropped to around 25Mbps which results in throughput speeds around 22 Mbps.
If Kitz found herself in that position she might well be catawalling most of the night !
Kind regards,
Walter

>> there is a good chance that your initial speed will degrade over time due to power cut-back to reduce cross talk on competing twisted pairs.
Thank you for that info. Out of curiosity, does this not happen with the Huawei dslams too?
-
@ Kitz,
As it's mentioned without qualification on the Wholesale web site** I expect you are correct but I've not observed that situation myself.
** Here's an extract on one of our "Superslow" lines from http://www.dslchecker.bt.com/adsl/adslchecker.welcome
Your cabinet is planned to have WBC FTTC by 31st December 2012 (but we hope it's this week). Our test also indicates that your line currently supports a fibre technology with an estimated WBC FTTC Broadband where consumers have received downstream line speed of 3.9Mbps and upstream line speed of 900Kbps. (We understand that these figures are sometimes adjusted after the cabinet is commissioned.)
The actual stable line speed supportable will be determined during the first 10 days of use. This speed may change over time, to ensure line stability is maintained.
Kind regards,
Walter
-
Thanks for the additional info.

I could be wrong, but Id assumed that was to generally cover themselves against any changes in line condition?
>>> I expect you are correct but I've not observed that situation myself.
I dont know about FTTC as thats all new to me and hence my query, but afaik all of the exchange MSANs (BTw or LLU) seem to experience some sort of degradation over time due to cross-talk as more lines are added. It can normally be seen by looking at a DMT tool graph on a good line, where tones in the 7/8Mb mark arent as fully loaded as some of the latter frequencies. :/
