Not a lot of time, but you certainly have FEC/interleaving on.

DLM has allowed a maximum delay of 10ms, and has set an INP of 4.00. Those figures are both slightly higher than the standard (which is 3.00 and 8ms), suggesting you are experiencing more interference than the norm, and were getting too many errors.

The overhead applied by FEC is 12/56, or 21.5% of the bandwidth, which will explain a drop in sync speed.

Turning the OR modem on and off all the time will not do your connection any good whatsoever, I did it because I had a flaky connection, ended up far worse than the initial installation, went do from 74 Mbps to 58 Mbps, and since it was just at the level that I was promised before having it all installed there was nothing I could do, I did eventually have an IP profile reset after X visits from OR, and that was only because the DLM gave me a ping of 35ms + and latency and jitter became a real issue, it to 12ms but now settled at 20ms and my speeds are 73.5 Mbps and 19.9 Mbps, and thats real time speeds, not a speed test.

Good luck, just leave it alone for about 1 - 2 months then complain.

There's definitely a reduction in speed and timing performance i will give it a week and re test the stats. average ping rate was around 25ms before issues now its 35-40 i may contact openreach but there is people in my street getting fttc services so it may be crosstalk.

Thanks guys for the help and advice the reduction in speed ain't a huge issue but ping rate as well not too pleased about.

Regards
George

My Latest Stats can anyone confirm line state/any faults

Ouch. SNR looks bad too. --pbParams may give further info.

How do you get --pbparams

xdslcmd info --pbParams

Thanks here's pbparams

Looks ok - you're firing on all cylinders. Just a bit noisy.
