In reply to a post by MrSaffron:

Bursty noise is something ADSL has to accept sometimes, e.g. it can be as simple as a train going by on an electric line every 30 minutes.

14,000 CRC errors a day (if that is them) is not that bad. Is it affecting throughput?

If these are just upstream it is more complex, since upstream has no DLM, and upstream is more likely to be affected by telephony issues e.g. filters/wiring/joints

if i plug the router into the test socket on its own and call my phone number via my mobile, i get loads of upstream errors
100 per min
sometimes it can hit the 1000
was told my errors are far to above the thresh hold by my ISP and that it does indicate a real problem
Web pages are slow to react and i have really bad packet loss at all times.
Gaming online is now impossible
BT could see it was so bad that they put a hard cap on the line to try fix the issue
It hasn't worked
My isp said it does sound like a filter problem, but as i have tryed everything at my end, they think it could be the filtering at bt side of things

Dodgy joint somewhere is where my money is

the last time i had upstream errors "December" the adsl would drop every time the phone was used.
They swapped everything from the house to the exchange and was ok for 2 days then i got this
What i will do is run the router from the test socket with another filter just to show you the errors
and my line is now on interleaving at my request, but does not help any

ok this is me ringing my own number with only the router on the line for 5 seconds

A fault that needs people to physically check bits of the line and not be played around with remotely looking at the DSL stats.

No point in all the pings with the line behaving like that.

So do you think i should go with the engineer visit and hope for the best this time

Thats my upstream stats just incase ya think its my downstream

It is very variable with the engineer visits, since at first glance the line stats are ok only when you drill into the error stats, which the site engineers may or may not be used to.

ADSL is a specialist subject, and while the engineers are trained, they are not ADSL experts. So be sure to explain the issue arises only when using the telephone, don't confuse things with pings/speedtests, just stick to the raw ADSL errors.

Ok we have 2 engineers that cover my area
One is great and knows all about line stats and errors, and will listen to what u have to say and look at the errors
the second one comes into your house tells you to leave him to it then walks away saying its your fault
The good engineer did say that i should report him as he has had loads of complaints about him from houses he had to go back to and fix the faults
Will give it a go and hope i get the good guy

I seem to recall from your other posts that these problems started around Dec last year. I posted to some of your posts then. I had the same identical problems as you have. I to had many engineer visits and my line was capped. This was good for a few days then the problems would just restart eg resync and very high eroors on upstream only. On the very last visit i even had my ADSLNation faceplate ripped out and replaced by BT with one of theirs. Even after the visit the problems remained. That is untill a week ago when one day the router rebooted at a higher sync and the upstream errors and problems seem to dissapear on its own. My connection seems OK. My problems all started when BT upgraded my connection to ADSL2+ which i didnt ask for in the first place. I dont no how long this stability will last.
The only other thing that has happened since my line mysteriously correcting itself is one of the neigbours has sold up and left the street. That house is now vacant. I now that ADSL2 is more prone to interfernce and noise. I currently suspect either some faulty equipment at that house which is now removed or cross talk on my line which for the time being is not effecting me. The new occupants are moving in next week so will keep an eye on my connection to see if the problem returns when they move in.

Did your problems start on a upgrade to ADSL2+

Had it before the upgrade
I do think i have the same problem as you and am sure Mr S got it right with the bad joint reason
Also found that my neighbour has the same fault as me but does not want to risk a call out fee
