My telephone exchange went down for 1 day over a week ago. When it
came back up I got my telephone line back but no broadband. I went
through the usual checks in my home and on my 2 computers, everything
ok. After various frustrating calls to both BT and my ISP (tesco.net)
I finally got someone to beleive that it is the exchange that is at
fault and it no longer seems to support broadband.

I went to various speed checkers online (at work) to test my number
and they all either said the line doesn't support broadband or I will
get a speed less than 512kb. Before my line was registering over 3MB!

My ISP have sent a request to BT to look at the exchange as they
thought it was strange as well. I'm still waiting to hear back.

Does anyone know what the cause of this may be and what chances do I
have of getting my broadband back?

(I have written a compaint to BT as I rely on broadband at home to
work and I have lost nearly 2 weeks!)

What's your telephone exchange name/location/area code?

George

Telephone exchange is Ayr (Scotland) code 01292, used to register
speed up to 3.5MB on BT checker, sam knows, sky and I used to get
around 1.8 - 2MB speed on my connection. I used to check it quite
regularly.

Sorry, that's not enough since there is more than one exchange
in Ayr. The next two digits of your phone number will
determine which.

I've noticed that WSALL (01292 44) apparently had some work
done on it late last night that caused a couple of synch drops
for around an hour each. Also my synch speed has slowly
dropped over the last month or so with nothing different
happening at my end - I'm waiting to see if they've fixed
anything...

Should be OK - see:
http://www.samknows.com/broadband/exchange/WSAYR
OK for ADSL, ADSL Max and SDSL
Also OK for LLU from Sky and Talk Talk

George

Thanks

I checked samknows already, checking my number on it says I 'may' get
0.5mb on the line but in brackets says (engineer visit may be
required). Samknows used to say 3.5mb up until 31st march this year,
day the exchange went down. I can't get broadband at all at any speed.

BT's checker says "the line won't support braodband".

I'm trying to get an explanation from BT and my ISP has sent a request
to them to check it!

If you already have broadband on your line, checking it against
availability checkers will give false readings. The result "the line
won't support broadband" can be generated by already having broadband
active on the line !

There are many ADSL line test sets, a representative example is at
http://www.exfo.com/en/Products/Products.aspx?Id=369
just get them to put one on your line and stop faffing around.
A line is just a pair of copper wires, with resistance,
capacitance and inductance, each of which is measurable,
it passes audio frequencies, how well ir carries them,
(which is it's frequency response) is measurable.
There are CCITT specs, which it can be characterised
against.
Openreach and ISP's just keep passing the buck
and give you the runaround, instead of actually
measuring anything.

Too right they do!!

I've emailed my ISP to check up on progress. Just checked samknows
today as well. Checking by my phone number I still get the same
results as before:

can't get 2mb
can't get 1mb
may get 512 (engineer visit likely)
may get 256 (engineer visit likely)

but checking by my house number and postcode gives:

can't get 2mb
may get 1mb
can get 512
can get 256

which is an improvement from last week.

What one to beleive though, I'm not at home so can't check right now.

That's they only realistic approach

Samknows is very handy, but is a best efforts site, only as good as the
information it is fed and a bit of clever guesswork on top to fill int
he gaps, even if samknows told you you could get 24Mbps ADSL2+ from WBC
next week, it wouldn't help you persuade your ISP of anything.

If it was working before and it now fails to work (preferably with more
than one router) and with with all other
wiring/filters/phones/faxes/modems/answermachines/skyboxes unplugged
then speak regularly to your ISP until they give you a time when
OpenReach will be visiting.

Going back to the original post, the phone came
back after the exchange outage, and speech quality
is acceptable?
If so it's fair to assume you have two physical
copper wires between you and the exchange,
else the phone would have problems.
One hypothesis for the outage is a rewiring
jumpering job at the exchange as part of rack
relocation or something of that ilk. Should
be transparent to subscribers and take a few
seconds, but can go pear shaped.
An underground plant, street cable fault,
can take longer to fix, particularly if a splicing
job is involved.
Shouldn't happen, but split pairs can happen.
You get your own wire for speech, but someone
elses return wire, an ADSL killer.
Exchange outages can also result from
lightning strikes, and it could kill your modem,
or your bit of the exchange DSLAM.
FOR ALL of these, your modem/routers
control panel should give you line/link
status, and verify if you have carrier at all.
Your modem/routers control panel is
your guide to what's wrong, you should
be seeing carrier, it should be
reporting attenuation and S/N ratio.
If it isn't then coincidentally your modem/
router died, worth checking direct on
the incoming line without your ADSL filter
and phones connected, just to rule out
the filter, or your DSLAM isn't working.
Your case is it was working, it isn't after
the outage, fix it. And for starters send
someone with a
decent ADSL line test set.

done that! I can tell they are getting fed up with me calling but it's
the only way I can get answers. They have now arranged a BT engineer
visit to the exchange finally! Hopefully in the next couple of days
I'll be running again.

Ok BT have apparatnly ran a line test on my line. My ISP phoned me to
say that my modem was switched off so the line test failed. It was on
all day and has been for a while now. I was staring at it when they
phoned.

Anyone know the reason why a line test would fail if my modem was on
(adsl light was on as well btw). BT won't admit fault!

Perhaps you could ring BT and ask them to prove that your modem was off!
Would they get the same result if there was a break on your line? BTW I
presume your modem is correctly plugged into the BT master socket and all
other "user" extensions are disconnected?

Wouldn't want the embarrasment of finding that someone has broken one of
your internal extension lines ;-).

Almost certainly because they were testing the wrong line. Or the line
was so bad they didn't see the modem.


Keep belabouring them. I think they have theoir wires literally crossed.

Stick the mains straight across the phone line and then complain to BT
that the voice circuit has all gone as well. Act totally innocent.

I have the modem plugged directly into the test socket on my NTE5 (via
filter of course). I've triple checked that on a number of occasions!
no extensions are plugged in. ADSL light is on and modem is showing
downstream of 2272kps, upstream of 288kps. Still no IP address from my
ISP.

Do you know how to access the router's diagnostics and log ?

First off you need to know if you have an active authenticated PPP session.
