BT line rerouted?

Until recently, my 1Mbps connection was relatively stable - on the margins,
but I could cope with rebooting the modem every now and then. I know I'm on
the limits for the service, and previously 512Kbps was more stable.

Anyway, as of about three days ago, my SNR figures have changed
dramatically dropping from a fairly consistent 10-11dB to between 3-4dB. At
the same time, Fujitsu has been out and about doing work on behalf of BT
putting in lines for a small new complex of houses and flats just down the
road. Is it likely that this work has seen my line unclipped from its
previous route (which the DSL engineer deliberately chose to get me the
best possible connection 12 months ago) and put on a less favourable route
for me. The line is now dropping frequently (100 drops in 7 hours... since
I last rebooted the modem), and nothing has changed internally to affect
this.

If the work that has been done has adversely affected my service, do I have
any rights in respect of it being put back to how it was (assuming
something has changed)? How do I even go about finding out if something has
changed?

Cheers

The only way will be to raise a fault with your ISP & let them
progress it to BT.

It could be that the work they are doing has physically disturbed
your witing in some way & that it may settle down once they have
finished.

What ever the cause the only way is to raise a fault with your ISP
about your random drop outs & let them run with it..

Feared as much. Unfortunately, I'm with Bulldog... Can't see them wanting
to run very far with it at all...

Contention, Contention, Contention!

If you're favoured, all the engineers can do is provide a temporary
alleviation just for you.

As broadband traffic builds up, things can only get even worse.

Buy youselves books of 2nd-class sticky stamps before the price goes
up again.

Come on Reg - the visible effect of contention is some lowering in speed
(try checking the network traffic graph on Windows XP's Task Manager) so
this seems a spurious response when the guy has noted a change in SNR on
his connection back to the exchange. In any case, Bulldog is not one of
the BT Wholesale supplied ISPs, so while there's a chance of contention,
it seems especially unlikely (check the 'news' about Bulldog in the last
two months and you will see they stopped phone orders and laid off staff
so the odds of contention from extra customers at an exchange are poor).

Its the same sort of guessing that always comes out in his posts. Im
suprised he doesn't just blame the female Prime Minister we once had... What
was her name?? Err ? Maggie! Thats it !

I must admit I don't understand the details of how the Internet works.
But I do understand the fundamentals of communications systems. They
don't change over the years.

Reduction in "speed" seems to be the most prevalent complaint.
Undoubtedly, this is due to Contention. ( That is a good word to
describe what is ocurring. )

But when the functions of servers themseves become overloaded a great
variety of apparently unrelated problems appear. People have no idea
whether a suddenly appearing problem lies in their own equipment or
whether it lies somewhere in the vast realms of the system. Most
likely it is in due to Contention in the system.

The best thing to do is wait to see if the problem cures itself. I
have long got past the stage of reformatting the hard drive as used to
be recommended by the so-called help desks.

But help desks are hardly much better than they used to be. Not
knowing any more about the system than their customers they still
automatically refer to a stock list of recommendations.

I have Windows 98, OE6 and IE. If it works I do not attempt to fix
it.

=========================================

And nearly always, if a problem occurs, within a few hours or so the
system partially restores itself. It's all due to millions of
customers contending among themselves. Not forgetting contention
between Internet providers. Survival of the fittest indeed!

Tarzan and the Law of the Jungle prevails.

Incidentally, it was Maggie Thatcher and her ilk which brought about
the end of the good old reliable GPO Engineering Dept. It did not
generate any immediate financial profits for the sharks in the Square
Mile of the City, so it had to go along with the best of the country's
communications Engineers.

So now look at the chaotic mess you nincompoops voted for and stop
complaining about disappointments in the misnomer of usable bandwidth.

Most of you don't have the foggiest idea what Bandwidth means.

Just continue paying your Direct Debits and phone bills to keep your
service poviders rich and happy.

Please explain how contention can affect SNR.

Cross talk between pairs in the cable between your house and the
exchange is a source of interference and noise. It tends to increase
with cable length as does attenuation.

You are contending with other users of the cable. If there is nobody
else using the cable you don't get any crosstalk. You cause just as
much interference to other users as they do to you.

Similar sources of noise and crosstalk exist in the exchange and its
equipment.

Most problems can be traced back to contention with other users. What
a nice reliable, trouble-free life you would have if only you and a
recipient were using the system.
