should be fine setup a BQM some T# timeouts are bad

So,e downstream levels are too high, out of spec and far too many errors. There may be a local fault.

Check with Area faults on 0800 561 0061 If you have a VM landline 150 this goes down to post code level. You could also try the web page status, but this is not recommended as it only covers issues that affect a very large number of customers.

VM will not dispatch any technicians while an area fault exists.

If no area faults found:

The primary place to report faults or for service requests is Customer Services on 0345 454 1111/150 if you have a VM landline or wait two or three days for a VM staff member to get to your post.

Hey graham1705, thank you for reaching out and I am so sorry to hear this.

I can see you've spoke to someone from the team, did they manage to help at all?

[graham1705]

hi got someone coming out to have a look

[Zoie_P]

Hi @graham1705, 

Thank you for letting us know, we hope your visit goes okay and please keep us posted.
Thanks,
Zoie

hi nice bloke called and dropped the power levels by 3db and said no noise on line 

[Matthew_ML]

Glad to hear this, is everything now okay with the connection? 

[graham1705]

had engineer out fitted a 3db AFM-3 F signal attenuator with droped downstream signal but he said the upstream would go up a little bit at was at 47db

had some done work done on the exchange not the green/gray cabinet and the upstream signals at 49db 

and geting loads of t2 59 timeout and some t3 3 timeout

[legacy1]

Your power levels was fine without the attenuator the problem is noise setup a BQM should show this.
