Recent drop in IP profile
Hi All,
Over the last week or two I noticed that I can no longer hold onto my line speed. At night he SNRM drops below 1dB and ultimately there's a resync which lands me with a lower sync speed under those conditions. This now happens after more than two months of holding onto 7616kbps with no dropouts and with a healthy target SNR of 6dB.
The drop in SNRM is gradual from about 21:00h onwards and a resync will invariably take place at any time between 22:30 to 02:30h. I have tried resync'ing when the noise is low to get a lower but still above 7392kbps sync speed, so that I can regain an IP profile of 6500, but even with a lower sync speed of 7448 I wasn't able to hold onto it forever. After a couple of nights it dropped it again.
Initially I suspected a degrading adsl filter, but I can't hear any noise on the line. When a drop out occurs the modem reports loss of signal due to excessive errors. Indeed, I have measured up to 28 errors per second (average over three days) before a resync occurs. This is almost three times higher than what I used to get earlier in the summer.
Last night's resync landed me with a profile of 5500 which is 1Mbps lower in terms of throughput.
Is there anything I could do to keep my summer performance, or should I accept that the nights are drawing in and this is the way of things to come. Have you noticed lower sync speeds, higher error counts on your lines?

Have you plugged it into the Master Socket? 
Makes a change for Micki to be in trouble
What do you mean? I'm always in trouble - just don't come here to cry about it! 
I do not have a conventional master socket I'm afraid, but I have disconnected the bell wire and when I have (in the past ) removed all other extensions to test it, the difference in attenuation was nill. My attenuation is 38dB (2.7m from the exchange).

The performance of your line is impressive! That's how many error corrections I get in less that a couple of seconds!
I have long disconnected the bell wire. All my telephone extensions are new and I doubt that I will see much of a difference if I were to connect to a NTE5 directly (I don't have a surface mounted master socket in my house).
