Broadband Speed Test

[The Natural Philosopher]

So obviously they are watching last weeks Corrie on catchup.

[Bob Eager]

It's set by BT and their implementation.

[The Natural Philosopher]

which is then all te line will reliably do. :-(

Both are true except is OPENREACH who do the capping unless you are LLUed

[Bob Eager]

Pretty reasonable for straight ADSL.

And about a billion times better than Thumper!

[Andy Burns]

There wont be. They install a multi-pair cable linking the old cabinet to the new cabinet with the VDSL kit, when you upgrade to FTTC, they jumper your line across *and* back between the cabs ...

************ -------------fibre------------> newcab

• * ^ |

• Exchange * | |

• * | V

************ -------------copper-----------> oldcab --copper--> house

So the PSTN part of your line will still travel over copper all the way from the exchange (the distance will increase by twice the separation between the old and new cabs but this is insignificant).

The VDSL part of your line will only travel over copper that's your distance from the old cab, plus the distance between the cabs, but this ought to be significantly shorter than your current distance back to the exchange.

Each subscriber who switches over from ADSL to VDSL consumes two pairs of copper between the old cab (which may be serving hundreds of houses) and the new cab, and one port on the VDSL kit (which may have as few as

96 ports)

The moral is when FTTC comes to your area, make you mind up whether you want it or not, and if you do, get your order in quick before everyone else does ...

And what is that? I've never really had a problem with mine, seems fine for what I use the internet for. Though higher speed can never be a bad thing ;)

They do sometimes supply over copper as ADSL Den...

Depends on who does it what time of day etc...

Think yourself lucky you can get 1.4Mbps sync rate. A mile down the road from here and they are lucky to get 0.5Mbps.

BT do apply a cap that they pass back up to the ISP so that data isn't fed into the system faster than it can fall out the other end. These steps are 0.5Mbps once you get above silly slow speeds or at least they were. I think things on this front have changed recently and the steps may have become smaller. It was a bit annoying to have a sync speed

50kbps below the next 0.5Mbps step up...

C'mon - you know you WANT it

Just think of that poor mr branson with no train franchise, where will he get his next buck ?

[Sam Plusnet]

Err... They installed FTTC at my exchange - and more specifically to my Cabinet [1]. No order from me, & no email from my ISP - but it's done & my speed (almost) doubled.

You do need to place an order if you want FTTP (fibre to your house) - and pay for it.

[1] This can be a great disappointment to some people. They hear that their exchange is being FTTC'd - and they later discover that only some cabinets were upgraded & theirs wasn't one of them.

Round here it mostly correlates with distance to the exchange with the folk who live next door getting astonishing performance. But there are strange blackspots connected to good exchanges with lousy performance. >

I think there is an element of serious household dependency present depending on how old and complicated the internal phone wiring is. It only takes one dodgy joint in the entire path and throughput is crippled. A neighbouring village has a maximum download speed of 512k and the average speed would be beaten by bonded ISDN. Not surprisingly they are an experimental zone for high speed internet over microwave.

I reckon it is worth trying your modem in the BT master socket with all internal wiring disconnected to see if your line back to the exchange is capable of anything more. No harm in trying. I honestly didn't expect to get anything at all since my internal wiring is very simple and good quality new cable but the difference was +50% on sync rate.

The bell wire hack worked wonders here much to my surprise and I suspect it will work for many of my neighbours too. There is some poor soul just down the road with only 256kbps. Being on the wrong side of the beck from the exchange is an automatic -1Mbps rate loss too.

It may be relevant that we are fairly close to a TV transmitter.

[dennis]

Except I know they don't go to different exchanges.

As usual you are wrong again.

[Hugh Jampton]

Thank you - you've convinced me. That nice man does need the money :-)

I WANT it !!!!!!!!!!!!!! (I think)

:-)

[dennis]

Not in cabled areas.

[Andy Burns]

Err, are you sure you don't mean they upgraded you from ADSL1 to ADSL2+?

I don't know of any ISP giving away FTTC upgrades for free, and you'd need a new modem and probably router too to get FTTC speeds.

[Dave Liquorice]

A TV transmitter shouldn't make much difference but MW ones will. R4 Tyne 603, R5 Live 693, R Cumbria 756, R Scotland 810, R Cumbria 837, Talksport 1053 & 1089 are all currently putting dips in the number of symbols that the carriers near those frequencies can carry. Probably knocking 0.5 to 1Mbps off the sync speed.

[Sam Plusnet]

Oops! Yes.

Prolly some questionable cabling from BT..

Which can work well provided there aren't too many obstructions around like Trees they can kill that..

Doubt that would have anything to do with it. That radiation will be above your heads, they go to some lengths to make sure of that. Its very expensive to produce, they don't want to waste it illuminating the ground!..

Look on the bright side, the BBC are planning on shutting some MW Tx's down soon...

What do you not understand about the word "sometimes" ?...
