master socket

i need some advice please.
when checking the master socket
i found the pairs have been split
i.e orange and white should be used
but i found orange and green have been used from the master socket to
the pole the affect of this would mean they are not twisted pairs.
how will this affect the performance of the broadband.
thank you.

Could you take a digital photo of the socket wiring. You could then upload to such a site as flikr.com and post a link.

Also posting your router stats might help. See http://kitz.co.uk/adsl/frogstats.php

My drop wire from the pole isnt twisted cable, it's just a 2 core stranded copper cable. I havent had any problems at all with it.

The most likely reason why yours is like that, is that one of the other wires has a break in it. So un-wiring it and putting the broken wire back in so the colours match may have a negative result.

thank you for your reply
my son has just moved in to this property
when i checked the master socket i discovered
the white wire was disconnected and replaced
with the green wire by a bt engineer at some point
which would indicate a fault in the drop wire at some
time.
which i think is wrong this would mean they are not using
the twisted pair and this could lead to interferance on the line.
thank you.

Yes it may cause a problem.

Normal CW1411 drop wire consists of 2 twisted pairs Or/Wh & Gn/Bk with twist rates / lay of 89 and 95mm.

As there could be 50 metres or more of untwisted cable in the drop it will be slightly more susceptible to noise in both DSL and voice bands. Is there any background noise on the voice circuit? If there is then get the voice provider to resolve it.

It certainly could.

I don't have any idea how much but is likely to be proportional to the distance from the master socket to the next joint. That might only be a few feet.

Router stats might be more revealing. For instance if the line is syncing at full rate the split is irrelevant..

than you mhc
the drop wire will be about 40 m
the voice is ok
i think this must have an affect on the broadband
as you are strongly advised not to use cheap
extention cables for broadband only use
twisted pair cable.

When I moved into my current house in 2003, it still had a bt rottary phone. the drop wire came down from the pole outside, through a bakerlite GPO Block Terminal No 20/4 then to the telephone.

The BT engineer at the time said it's an old line, but it works so BT isn't going to change it. The line is around 1600m in length to the exchange according to the attenuation, and none of it is twisted. I'm not having any connection/noise problems at all. I have maximum sync and a stable connection.

Unless your having a problem, I wouldn't worry about it.

the line is 6.8 km in length
and i am trying to get the most out
of it.

And what are the current connection speed, attenuation and noise margin. It is feasible it is performing very well already for the line length
