Something wrong

[#1]

OK, will do. Thanks.

[#2]

The test on the phone line isn't showing any issues. Can you confirm that you've been able to test the phone in the master socket?

[#3]

The phone line problems are intermittent - they are only there when they are there, so using the test socket doesn't help.
The broadband is still at a DS noise margin of 9.5dB, it has always previously been a long term steady 6dB. Is there anything that can be done about this?

[#4]

I could reset the SNR, but if there are periods of noise on the line it's very likely that the SNR will head back up. Let me know if you'd like me to try an SNR reset, keeping in mind that we can't do another for 10 days/.

[#5]

OK try a reset and I will monitor what happens. Thanks.

[#6]

Ah-ha.
The target SNR was actually 6db already, so I was a little suspicious of why it was currently at 9.5db. It turns out your line had been banded to ensure stability, you were syncing at the top end of the band and therefore the increased SNR was expected. I've requested the banding get removed which should happen in the next hour or so.

[#7]

Well that's worked, you're now synced at 16674 - this gives a profile of 14700.

[#8]

OK, returned to normal this end. Thanks.
What would have caused the banding?

[#9]

It's normally due to a period of disconnections or noise on the line, the banding increases the stability so tries to keep the connection working by possibly sacrificing some speed.

[#10]

As mentioned here - if you can post the TG582n Full DSL stats we can take it from there.

Hello,
Slightly faster today. I have been trying to disconnect broadband via the router before I turn power off at night.
Here are stats. I wondered if the FEC seemed rather high.

[#12]

Yes the FECs are high, but although the CV(CRC) & ES errors are a touch higher than one would like, the HECs are rather more of a concern.
Do you still have this intermittent noise on the line? Try the Quiet Line Test 17070 option 2 if need be.

[#13]

Yes. I still do get noises on line on incoming calls. I had a call this evening with some noise on it. But again, testing using Quiet Line doesn't show up anything.
Here are stats. from about one and a half hours after previous ones:

[#14]

Just had another incoming call from same source. Once again, noisy incoming line. Again, no call no noise.

[#15]

Is the noise just on incoming calls from that source or from several sources?
If just that source, then it is likely that the problem is on their line.
