Exchange upgraded, but Infinity not available

I live in Carterton, which recently had its exchange upgraded to fibre. Unfortunately, I can’t receive it although I only live 935m from the exchange (as the crow flies). I’m not sure where my local cabinet is. Currently I get around 4.5mb. Samknows lists FTTC as available to “some areas”: http://www.samknows.com/broadband/exchange/SMCAR

 

I’ve looked at many of the links listed in the forums and can’t find anything on when I’m likely to be able to receive fibre speeds, or what the issue is likely to be. I know there's a list of generic reasons on BT's site, but I'm after something more specific - if possible.

 

Frustratingly, BT keep sending me letters in an attempt to get me to order Infinity (I’d love to!) and I know some of the houses in the vicinity are able to receive it.

 

Can anyone help? Thanks in advance.

Re: Exchange upgraded, but Infinity not available

an exchange can be declared accepting orders when only 10 cabinets connected to it are fibre enabled. It could be that your local cabinet isn't currently on the rollout plan, or it is, but not done yet, or it might not be economically viable for it to have fttc enabled on it.

Re: Exchange upgraded, but Infinity not available

If you enter your telephone number here :-  http://www.dslchecker.bt.com/adsl/adslchecker.welcome  does the response mention anything about FTTC speeds and estimated availability dates ?

Re: Exchange upgraded, but Infinity not available

Rather depressingly, see below. It's somewhat irritating, given that the house is 5 years old, the estate is around 7 years old and (as I said) it's 935m from the exchange.

 

Your exchange is ADSL enabled, and our initial test on your line indicates that it is VERY UNLIKELY you will be able to receive fixed 512Kbps broadband service due to the very long length of your telephone line. However, your order will be accepted if you still wish to order. An engineer may need to visit who will, where possible, supply the broadband service.

 

Our test also indicates that your line currently supports an estimated ADSL Max broadband line speed of 1Mbps; typically the line speed would range between 250Kbps and 2Mbps.

 

Our test also indicates that it is VERY UNLIKELY you will be able to receive fixed 512Kbps ADSL2+ broadband service due to the very long length of your telephone line. However, your order will be accepted if you still wish to order. An engineer may need to visit who will, where possible, supply the broadband service.

 

Our test also indicates that your line currently supports an estimated ADSL2+ broadband line speed of 1Mbps; typically the line speed would range between 1Mbps and 3.5Mbps.

Re: Exchange upgraded, but Infinity not available

Depressing indeed !  That response implies that either there is no current plan to upgrade "your" cabinet OR that you are connected directly to the exchange (unusual over that distance) and therefore cannot get FTTC anyway.   If FTTC was on its way, the response would have included a speed estimate and a "planned" (cough) availability date.

 

None of the above precludes some kind of database error, but that really is groping in the dark  -  oo-err missus.

Re: Exchange upgraded, but Infinity not available

Hi Silver2495,

 

From what the information from the BT Wholesale database says, are you sure your exchange is 935meters away? As a line length of around 0.9km I would have estimated a speed between 16mb to 20mb on ADSL2+

 

You can check roughtly how far away you are from your exchange by going to the Samknow website. Under locality for your postcode/phone number it will give you a straight line distance. Please bear in mind that the landline length maybe longer.

 

If your a BT Broadband customer can you also post your adsl line statistics as it will also give an indication of how long your line is (see how to get line stats below for help)

 

ADSL Line Statistic Help:

If you have a BT Home Hub like the one below...

 

Then:

1) Go to http://192.168.1.254 or http://bthomehub.home

2) click Settings

3) Click Advanced Settings

4) Click Broadband

5) Click Connection or sometimes called ADSL (see picture Below)

adslconnection.png

The direct Address is http://bthomehub.home/index.cgi?active_page=9116 (for bthomehub3)

 

You will need to copy and past all the adsl line statistics ( Including HEC, CRC and FEC errors). You may need to click " More Details"

 

There are more useful links on Keith's website here: If you have an ADSL connection, please select this link

 

Don't have a BT Homehub/Voyager?

 http://192.168.0.1 for a netgear router and look for ADSL adsl statistics with information like noise margin and line attenuation, connection speed

• http://192.168.2.1 for a belkin router and look for ADSL adsl statistics with information like noise margin and line attenuation, Data Rate

 

 

Cheers

@biffo1963

 

Long EOL are actually more common than you think. I once had one that was just over 7km long.

 

EOL lines aren't so much apparent the closer the premises is to the exchange but more rather when the line was first installed.

Re: Exchange upgraded, but Infinity not available

Thanks for the replies.

 

Helpfully, the Samknows locality checker thinks I'm 0 metres from the Exchange and can receive all services. I'm basing the 935m on a direct line (which I'm sure the cable won't follow) between my house and the exchange, calculated using Google maps.

 

Connection data:

 

DSL Mode:ADSL_2plus
DSL UpStream Rate (Kbps):895
DSL DownStream Rate (Kbps):5606

                              Down           Up
DSL Noise Margin (0.1 dB):      94           65
DSL Attenuation (0.1 dB):      455          287
DSL Transmit Power (0.1 dB):   193          124
