The house wiring was fully checked last Tuesday when the consumer unit was changed. Every socket in the house was megger tested and passed easily. If I get the opportunity I'll do a graceful disconnect and use the test socket for a while. Meanwhile I'll continue to monitor the graph and quiet line test.
The router transformer is plugged into an extension lead. I would have thought the power supply would control any spikes but do you think that might be relevant?
By the way, I live just outside Bedford.

Is it possible the glitch this morning was anywhere between my router and the exchange or even in the exchange itself? If so, as I'm so far from the exchange it could be an interesting problem to track down!
When two line faults were fixed a few weeks ago leaving me with hum on the line it transpired that the equipment in the exchange was causing it. I don't know how fixing a line fault could suddenly cause the exchange equipment to produce hum (like mains hum) but the Openreach guys changed something in the exchange and the quiet line test has been good ever since.

The daytime SNRM graph is looking very good, other than that small spike at 0836 ish. Don't want to see too many of them (something being switched on or off at a guess).
Whilst it's good to know that your electrical installation is fine, that will have no impact on this sort of issue which is usually down to poor/faulty switch mode power supply units (SMPS/U) used in all sorts of modern electronic/electrical equipment. Discharge lighting can also cause interference, sodium street lights, fluorescent lights and so forth, often when the tubes aren't up to spec. or are on the blink.
The Modem/Router PSU will have little effect on suppressing these type of problems, and the use of mains extension leads shouldn't make any difference. Sometimes if power cables are running parallel to the phone/router line within about 6", that can sometimes add to the problem.
Because your modem/router was obviously constantly on, as was you computer and monitor at 0620, they can clearly be eliminated from the equation.
Whilst whatever is generating the noise that went off at 0620 "could" be anywhere between you and the exchange, it is far more likely to between you and the Cab (how far are you from that btw?) or more probably very local and/or between you and the DP.
The first thing in these situations is to eliminate anything of your own or immediately adjacent - ie. a street light right outside for example - taking account of when this happened - I mentioned central heating - a controller might be responsible, but bearing in mind the weather, that might just be the hot-water side of things. But if you know the system wasn't on or didn't go off then, that could be eliminated.
Dusk to Dawn lighting, or IR lit security camera PSUs are the hot favourite IMHO (where the IR goes off in daylight).

I've checked the wiring to the first telephone extension after the master socket - blue with white trace on pin 2 and white with blue trace on pin 5. This is modern wiring I think?? I'll have a look at the master socket later. I will also try running on the test socket when the street light turns on/off to see if there is any difference.
As for the distance to the cabinet, I'm not sure. I should have asked the Openreach guys when they were here. I think it's about 1km.
I'll keep posting updates as and when I have more useful information. Thanks again for your help.

Quote from: martinjbuckley You realise you've now got me hooked on RSL and seeing what happens when I turn things on/off!
You won't be the first. It has been very useful for a lot of users REIN (interference) problems.
With some CFLs (also old CFL converters), individual lamps can periodically be an issue, it is a case of going round and checking each one. I've even heard of the odd LED one giving a problem. Dimmer switches can sometimes also be a big problem. Sometimes fluorescent strip-lights/tubes cause problems - and you've discovered the discharge lamp (street light) outside being a significant issue. I was going to say the later time would be due to the overcast conditions, but you said it yourself. Do you have a neighbour with whom you can check his stats (no need to run RSL) and just see if their SNRM drops when the street light comes on?
The HF SMPS transformer for the halogen lights is probably running at circa 30/40kHz, as can CFLs etc and it's usually when the harmonics are excessive that problems occur.
The wiring you've checked so far is the correct modern CW1308 standard. That's a good idea to try in the test socket as well once you checked out everything else. It will enable you to see if anything might need "rejigging" (I'll explain should the need arise).
With regard the hum on the line after the fixing of a line fault, this might have been due to the line being unbalanced due a fault in the exchange. If the engineer put you on a new 'E-side' pair (Exchange to Cab) the problem could have been at the exchange end on the new pair.
If you are about 1km from the Cab, unless your 'D-side' pair is poor quality aluminium, when Fibre comes, you might be lucky and get about 20/25Mbps.

You ought to look at your NTE5a asap, just to check if the engineer reconnected your bell-wire.
