Hi,
We had a noisy phone line fixed recently, and although that's made a big difference I have to face the fact that the error rate is still too high for comfort, running from the high hundreds to a couple of thousand ES per day. I'm really looking for ideas as to how I can address this. The error rate goes through the roof in the evening, from around 20:00 at night until midnight or sometimes a couple of hours into the next day, and that's accompanied by a drop in noise margin. However I'm not completely sure that of that link, because for example sometimes like today there are regular error even when the nm is over 7dB and not really changing with a pretty big drop. See attached for example.
Any ideas as to anything I can do to track the issue down? I can't see me making any headway with the service provider.
Thanks, Tony S
