The only issue that I'm cautious about is I've noticed people say DON'T mention broadband or they will send a broadband engineer.

That not it's point. It's that voice faults have higher priority than BB, by legislation.

I think the timing of the fault is of coincidence. What I suspect you have is an intermittent rectified loop fault on {most likely} your internal wiring or equipment.

Its not the internal wiring as the openreach guy plugged his meter directly in to the master socket of the house and called the phone line and his meter detected (I think it even made a constant sound) the voltage on the line. He said it was from the exchange as that controls the voltage of the ring.

Its just an odd fault to report as I'm thinking these 'script helpers' won't recognise the fault when hearing it, and do their line test, which will show nothing, then it'll be up to me to force the issue for them to send out a voice engineer out.

Just to update you guys on my situation. I called up BT on a Monday and requested a voice engineer. I explained a little about what the problem was to them on the phone (not mentioning broadband), and they booked an engineer appointment for Wednesday. On Monday night my router rebooted with these stats;

6. Data rate: 20000 / 73446
7. Maximum data rate: 21696 / 73468
8. Noise margin: 6.2 / 6.6
9. Line attenuation: 20.9 / 18.1
10. Signal attenuation: 20.7 / 18.1

The speed went from 63mb up to 71mb. But the one long ring on the phone still happened when someone called me. So on Wednesday the phone rang and the engineer was at the exchange and asked had the problem been fixed. I said no, the phone was still giving a constant ring. He said that he'd have a look around the exchange and see if he could see anything wrong. If he couldnt then he'd come to the house in 30 minutes.

About an hour later the phone rang normally i.e. "ring ring". Then I picked it up and he said did that work? I said yes, and asked what the issue was. He went in to some technical jargon about it being a fault in the exchange and that he had to make a call to an exchange in London. I didnt really understand what he was meaning, but he did a line test to check things were ok, and they were. So problem solved.

I guess interleaving went on again last night.

When I called up for that fault, which is now fixed, before the fault was even fixed the speed shot up that night. So I am wondering if they manually took interleaving off. Anyways it seems to be back on it seems. A shame really.. Hopefully its just because the weather is bad.

As a chronology these are the stats before I reported the fault on Monday 12th of January;

6. Data rate: 20000 / 64902
7. Maximum data rate: 21248 / 75209
8. Noise margin: 6.1 / 6.5
9. Line attenuation: 0.0 / 18.1
10. Signal attenuation: 0.0 / 18.1

The router rebooted on that Monday night and Tuesday morning the stats were this;

6. Data rate: 20000 / 73431
7. Maximum data rate: 21271 / 77151
8. Noise margin: 6.2 / 5.8
9. Line attenuation: 0.0 / 18.0
10. Signal attenuation: 0.0 / 18.0

And after a reboot to update the firmware on Thursday or Friday the router held good line stats. Then this morning it rebooted and these are my current line stats;

6. Data rate: 20000 / 64954
7. Maximum data rate: 21647 / 74373
8. Noise margin: 6.1 / 6.3
9. Line attenuation: 20.7 / 18.0
10. Signal attenuation: 20.5 / 17.9

As a side issue, your down upstream attenuation was present, disappeared for a bit, and has now returned.

Edited as per MHC's correction.

Downstream or Upstream? I believe you are referring to the latter.

I think thats the new firmware that got installed finally last thursday. I noticed that suddenly its displaying the full stats.

That happened to me following a recent firmware update on my HH5 (Software version 4.7.5.1.83.8.204 (Type A) Last updated 11/01/15). Rather interestingly, the first perceptible change was an approximately 2mbps increase in data rate (to about 59mbps) and my fastest ever speed test (about 55mbps). The gap between max and data rate was only about 1mbps at that point (as it always had been).

Sadly, it was not to last. After 2 disconnections in about 24 hours, interleaving was slapped on and I've now got a max speed of 59.7mbps, with with a data rate of 51.5mbps.

The net effect of all this is I'm now about 4-5mbps down on speed, although the link is now more stable. It used to drop out about once a day. Now it's been up for approaching a week.

nb. I should add that upstream improved after the firmware update and, unlike the downstream, has remained that way although the improvement is modest with upstream speed tests going from a little over 9mbps to a little over 10mbps.

Its interesting as I've never had any disconnections via interference. It's always been those stupid remote reboots every fortnight with BT company messing about with things.

I do sometimes wonder if these weekly reboots and remote management activities cause problems with the line.
