Have you tried a Quiet Line test?

Your QLN shows a few noise spikes at tone 190+
Your upstream SNRm is suffering the most...  usual culprits are internal wiring, faulty filters or a High Open.

The graphs shows signs not dissimilar to a HR fault.  Especially if the landline had rung or was in use at around 10:50.  The slow decline and then back up could be side effect of the whetting current.   Noise ingress on internal wiring could also display something similar though.

I looked it up this morning and now know what it is: whether I really understand is doubtful.
Quiet line tests are a bit of a problem: I hearing aids! I'll rake out my corded, but I'll still have that problem. There is no obvious noise, when using the cordless on full volume.

We did have a call, commencing 10:36 on 15th. As it was from my wife's brother, It would have been somewhat lengthy!

The previous owner had a hard wired extension through the cavity, vertically direct from the master socket to the room above, so no splitters et al.

I viewed the tone graph, FWIW, and found the spikes are at 192 , 211 and 244 (828, 909.9375 and 1056.5625 kHz). Is there anything significant about those? They seem to be pretty permanent.

Have a look at http://www.mediumwaveradio.com/uk.php . Those frequencies look like MW radio stations.

My test phone includes a high resistance connection button so often hear radio programs loud and clear when connected directly to the test socket.
It illustrates just how far we've managed to squeeze higher frequencies from the good old PSTN !

Kind regards,
Walter

Thanks Eric!
I found a transmitter, that I had never hear of about 16 km SSW of me. thode are frequencies .where the spikes are

828   Classic Gold 828   Fern Barrow, Bournemouth           270W   

909   Radio 5 Live           Fern Barrow, Bournemouth         250W

1053   Talk Sport                   Fern Barrow, Bournemouth          1000W

1197   Virgin AM                   Fern Barrow, Bournemouth           250W

1359   R Solent for Dorset   Fern Barrow, Bournemouth           850W

Are they of any significance at all in the case of this thread?

They won't be responsible for the ups and downs of SNRM at the weekend. As Kitz said, the most likely culprit is an intermittent HR fault.

Whetting current refers to the fact that electric current passing through a poor joint can temporarily repair it. This can happen when someone rings you - the ringing signal causes extra current to flow, and the quality of the joint improves, but it doesn't last.

Got wife to listen for noise (her hearing is superior to mine) and she heard no noise. I've yet to use a corded though. Today the up margin has been jumping around like a kangaroo on heat, that sat on a hornets nest. There is quite a problem with DSL connection

Code: [Select]
21 Apr 2017 20:25:50 Recording started

21 Apr 2017 20:25:55 IP address is now 147.147.192.217
21 Apr 2017 20:33:51 DSL connection dropped
21 Apr 2017 20:33:51 No DSL connection
21 Apr 2017 20:34:08 Recording paused
21 Apr 2017 20:34:14 Recording resumed
21 Apr 2017 20:34:15 No DSL connection

21 Apr 2017 20:35:11 Recording paused
21 Apr 2017 20:35:15 Recording resumed
21 Apr 2017 20:35:17 Unable to login to modem/router

21 Apr 2017 20:36:33 Recording paused
21 Apr 2017 20:36:36 Recording resumed
21 Apr 2017 20:36:38 DSL connection restored

21 Apr 2017 20:36:41 IP address is now 147.147.*.*

So I'm a bit stuck, as no noise no PSTN call reason.

I doubt it is at all relevant, but I have a MasterPlug tower. It has an input from the phone socket, and output to the router, so I ask if there is a downside to that configuration, that could be in part a culprit.

BTW just noticed the IPcanged @20:25, 20:36 and 20:44. Bit often isn't it?

Yes, it is. It is either indicating a problem with the equipment or a circuit with a defective connection.

Re..'high resistance' what sort of resistance value ?. :hmm:

Walter really meant to use the phrase "high impedance". The test telephone will present an impedance of many Mega Ohms to the circuit. The high impedance will not allow sufficient current to pass, thus not looping the pair and signalling a calling condition to the exchange equipment.

You mean the Billion router or what? The computer is a Dell refurb, probably about 9 months old according earliest files found.

Any suggestion as to what next? How do I approach ISP without some positive evidence?


All a b****y nuisance, as I've just "forced JLP to send someone out to troubleshoot my HDR,prior to requesting Humax to repair/ replace.

Please be aware that it is always difficult performing remote fault-finding.

As to the equipment, I was being somewhat vague, for it could be your modem/router or the ISP's DSLAM/MSAN or bRAS. As for the possibility of a defective connection, it could be anywhere in the cable between your home and the serving telephone exchange.

I think it will have to be a case of being rather patient and making careful observations, along with date and time, when those disconnects occur.
