Hooray for Fibre Optics

[joe]

Just changed over this a.m.

Fisrt BT speed test:-

est1 comprises of two tests

1. Best Effort Test:  -provides background information.

Download Speed
36385 Kbps
   
0 Kbps 38717 Kbps
Max Achievable Speed

> Download speedachieved during the test was - 36385 Kbps
For your connection, the acceptable range of speedsis 12000-38717 Kbps .
Additional Information:
IP Profile for your line is -38717 Kbps

2. Upstream Test:  -provides background information.

Upload Speed
8174 Kbps
   
0 Kbps 10000 Kbps
Max Achievable Speed

>Upload speed achieved during the test was - 8174 Kbps
Additional Information:
Upstream Rate IP profile on your line is - 10000 Kbps


I'll settle for that 

[Glenn]

Looks very good, now when is my street ready?

[Simon]

  Hope you enjoy it! 

[Bill]

Note to admins- I think the OP should be banned 


Looks good. Are there equivalents to SNR, attenuation etc on a fibre connection?

[Simon]

Only if he boasts too much, Bill. 

[zappaDPJ]

Congratulations! The upload speed is very impressive indeed, as someone who spends hours uploading files to servers that would be very welcome.

I'd be interested to know if the migration has had any effect on latency at all.

Lucky S*d

[Technical Ben]

Very good!
With fibre, does it suffer from the same "up/down" limit as cable? I would have though, as the light waves don't interfere the same as an electrical signal, you could send both upstream and downstream at the same time? With cable your up signal takes up some of the space of the down signal. But with optical, the two beams can cross (although they get some interference doing this).

[pctech]

Fibre is to the cab.

Loop from cab to your socket is still copper.

[Simon_idnet]

FTTC is still DSL but is VDSL on a very much shorter copper wire.

[Ham]

thats realy nice

how far are you away from the cab by the way ? and what was your estimated speeds before install ?
i am about 100feet away for our new cabnet BT says i can get speeds upto 17meg

[klipp]

I'm a mixture of depressed and jealous.

BT is probably estimating your distance from the exchange rather than cabinet.

It said 22 Mbit download estimation for me and I'm getting about 37-39 Mbit down and 9.6 Mbit upload (40 meters from the cabinet)

[joe]

I'm about 200yds away from the cab. BT had predicted a max speed of 21Mbs which to my mind made the upgrade debatable but in reality, thus far, I'm maintaining the initial speeds. BT speedtester gets as afr as carrying out the test predicting a max connection  of 38717 but then stalls - it's been like that for a week now  Cant have everything!

[klipp]

Does FTTC have IP profiling or an equivilant?  What I'm asking is is your speed subject to change based on noise factors and so on?

[Steve]

I think the management by BT is the same as adslx see here http://www.robertos.me.uk/html/fttx.html

The connection is still copper to the cabinet so the same noise/ interference issues will still apply albeit over a shorter distance

[klipp]

Thanks Steve.  I hope my exchange gets FTTC one day, although we're not mentioned on the scheduled lists.

[g7pkf]

I would just like fibre to my village.

bloody trains.

[pctech]

You mean you don't share this nostalgic view of our railways then?

[g7pkf]

No

This problem has now been identified, NOT SOLVED BT WOULD HAVE TO SPEND A FORTUNE in fibre to the village.

Yes you heard correctly, The problem is the whole of the village is affected, All because the BT lines from the exchange run on a bridge over the railway, Hence they are apx 2-5 metres from the OHP.

Took me a while to figure it out, But using remote login to a few friends routers i was able to plot that we all got a snr drop at the same time.

The correct resoloution would be for BT to fibre to the village and then mini-exchange to all properties. Will they do this NO as there is such a small number of users.

My temporariy soloution (will last about forever) was to investigate different routers, The best i found is a BT2700 Business broadband router, works well for inpulse noise and long lines Ironic isnt it .

at present i get 1-2 drops every few weeks, connection speed of apx 4-5Meg.

when its icy (and the electric lines arc) i get more drops.

But hey 1-2 every few weeks is a lot better than the 150+ a day i first started with

SO yes I HATE TRAINS

[pctech]

Only been on them a few times and cant say it was pleasant.

[joe]

Oops, spoke too soon - the wheels were bound to fall off.

Yesterday BT configured speed 37414 with speedtest d'ld of 35Mbps and u'l of 7Mbps
Today BT configured speed 2125 !!!!!

Support have contacted BT for an explanation.

[Rik]

Ah, the old 2M stuck profile lives on.

[joe]

Rik,

Enlighten me please. What is the old 2M stuck profile and why should it occur on fibre optics?

[Rik]

Fibre is still profiled, afaik. As long as I can remember, there's been a tendency for new connections to go off at good speed and then suddenly drop to 2M. However, with fibre, I'd suggest you talk to support asap.

[joe]

I did Rik, first thing yesterday morning and they have contacted BT. Still the same this a.m. 

[Rik]

BT aren't lightning fast, unfortunately.

[sof2er]

http://81.187.105.49/?incident=342

There was an incident a few days ago with BT where they upgraded all DLSAM software but the software capped almost all FTTC lines to 2 Mbps (2125k IP Profile).

I'm not sure why you still have it, it should've been fixed monday but seems your problem started yesterday so that's odd...

[Rik]

Thanks for the link. 

[pctech]

Have to say he doesn't mince his words does he.

[Rik]

He never has. Whether it's the best way to do business with BT I'm not sure.

[Bill]

He never has. Whether it's the best way to do business with BT I'm not sure.

They do seem to get things done though... If I had to switch ISPs for any reason (other than cost!), AAISP would be on my (very) shortlist.

[joe]

BT reset at 10.00am. Now OK again.

BT speedtest confogured d'ld now 38717 (test now hangs at this point and wont complete).

[Bill]

test now hangs at this point and wont complete

It's good at that

[sof2er]

Did you genuinely get 76 Mbps ? or was that speedtest bugging out somehow...I'm usually lucky if I hit the 38 mbps, it's most of the time around 35-36 mbps

[klipp]

Seems a tad unfair that some people get 35mb, and cable customers get 50mb, yet I only get 1mb.

[Lance]

76mbs would have been an error unless it is FTTP/H

[Rik]

Probably caused by the AV software.

[Steve]

The Speedtester ought to say "Please do not move away from your screen otherwise you miss it,you going so fast'

[Rik]

[joe]

I take anything over 35ish with a pinch of salt. It seems to be averaging out at 35ish. I've been using speedtest rather than BT because it was hanging on ie8 but having tried it on Firefox (3.6.3) it completes and gives the attached

[Rik]

Go away, you're making me jealous.

[psp83]

Ban them all Rik!

[Rik]

Don't tempt me.

[psp83]

Or find out where they live and I'll go downgrade them  

Now where did I put them bolt cutters 

[sof2er]

For a few days I was only getting 31-32 mbps, so after I today powered my modem down for 1 hour and then back up it's going at almost 38 Mbps now (Which does show that the re-synch thing is still there !)

[Rik]

Doesn't it.
