The re sync was me, to see if i would get somewhere near the 83mb/30.5mb attainable rates i had when i started monitoring the connection on the 27/5/14 , and to see if there was any changes with the interaction of the PTSN side,

Which now that i have lost some of the spare DS margin, which was 7.3db as well as 3mb off the attainable rate, the ds isn't as badly affected, but it will dip below  the sync rate when the phone is in use (outgoing/answering incoming calls)

The BT engineer  turned up as arranged in the afternoon, he had an exfo tester, did a VDSL test, which didn't show any problems, then he did a PQT and found an imbalance (was 36db on one leg iirc??) then following a TDR he located an issue at 5m from the NTE (crimped joint where outside cable enters and connects to the newer inside cable)  so he re made the connection  there and  at the outside gray wall box were the 6 pr cable comes from the ground, after testing from there as well, This unfortunately doesn't seem to of made a lot of difference,to the attainable rates ect, and there is still an interaction going on when i make & receive calls , but now when the phone rings, the DS attainable increases a little, and then drops down again,

Further to my last input, i just tried to use my land-line, and there is no dial tone,lol, and i can ring my number from my  mobile ,and it gives the ringing tone on the mobile, but nothing is happening at my bt phone, looking like i'll have to be reporting a voice (PTSN fault) or seeing if the isp will  get them BT to return and sort it , I bet it's at the PCP again, it's one of those old cast iron ones with a front plate that is secured 4 locking tabs which acts as it's door, and according to one or two engineers it's very limited for space,a pain to work on

[NewtronStar]

Hello Tommy45 will you receive an OR engineer visit charge on your next bill from your ISP on whats looks to me like a bloody good fttc line. 

[tommy45]

Hello Tommy45 will you receive an OR engineer visit charge on your next bill from your ISP on whats looks to me like a bloody good fttc line. 

Why , he found a fault  his equipment detected it, just because  i am fortunate to have a little spare SNR , and it had not progressed enough to become service affecting , shouldn't mean that  they ignore it,  why should we customers have to wait until it causes serious problems with  the services we pay for, ? not only that we do pay for the upkeep of the decaying  copper/ali pair in the horrendous line rental fees

From what i have read and from what previous engineers have said to me, there should be no interaction between pstn and xDSL services , had my upstream snr been only @6db, it be service affecting  drop-outs everytime the phone is used, i've been there before and what a pain that is

Plus, there's the fact that the ptsn service is now completely dead

[NewtronStar]

Why , he found a fault  his equipment detected it.

I am only asking as I've had a 7 month old HR fault on my line with PSTN issues on XDSL service, just would like to know if you got charged by OpenReach 

[tommy45]

Why , he found a fault  his equipment detected it.

I am only asking as I've had a 7 month old HR fault on my line with PSTN issues on XDSL service, just would like to know if you got charged by OpenReach 

Oh, sorry i read it as you thought that i would /should be charged,  Well  this is getting even stranger now, the PSTN is back working again, for now at least, weird , HR faults can be a nightmare,But if they OR find an issue from their tests then as far as I'm aware should be no charge, it's when they don't find anything you get fleeced, I don't think i will be in a hurry for another OR visit though unless it deteriorates  enough to become service affecting , as i think i got lucky this time , had he not had the exfo equipment it may of been a different outcome,

Because even though i was able to demonstrate the interaction  to the engineer, he was at first a little sceptical about it, saying that they accept that some times there will be this sort of interaction between the two services (first I've heard of that)  but  i did stress ,not that i really needed to, that the only reason it wasn't dropping out was due to the spare SNR  on the upstream , IMO in this type of situation DLM should be disabled or prevented from applying interleave , should they find it acceptable for the ptsn to cause issues with the xDSL service

[Black Sheep]

Of course, you're quite right that DSL and PSTN should not 'Cross' in any way.

As an aside, I use what we call a 'Trout Phone' (Please ..... we've heard every pun there is regarding said name  ), to listen on whilst my JDSU synchronises. If I can hear a 'Hissing' noise then there is a very slight HR somewhere that most tests will miss.

The problem is, the official 'Tapper' we are supposed to use wont pick this up, I believe it's down to the high level of capacitance within the 'Tapper' ?? Whatever it is, it won't highlight the 'Hissing' noise as mooted.

[tommy45]

Not sure if he did that (listen whilst  he got a sync, but he did at one point do a quite test whilst testing using his mobile  i think) Too early to tell for sure but  my error rates may be a little lower certainly the FEC on the upstream and Hec errors on the DS which OR don't count or aren't worried about, But there's still that  interaction between the PTSN and VDSL going on  question is what is next? wait it out, or  call them back again, ?  My bets would be it's at the PCP  but why it didn't show up  i can't say

RE: the hiss as the modem establishes a sync being audible on your "Trout" Phone  what exactly is one of those, do they differ greatly in comparison to a corded phone with a small degree of amplification ? would it be likely that this hiss would  be audible using a normal phone ?  If the tapper  is blue in colour  then he didn't break that out ,  just used his mobile and the hand held exfo tester, with a earth in to a wall socket  inside the house, and  a screwdriver into the ground  for an earth outside

[Black Sheep]

Yes, the 'Trout' is a very, very, very cheap corded phone. They were given to us back in the days of yore, to give to the EU if their rented telephone had gone kaput as an interim measure. So yes, you're own corded phone should be able to emulate the hissing noise if there is a HR fault brewing ?

He wouldn't possibly be able to carry out a 'Quiet Line Test' on your circuit, using his mobile phone. I would humbly suggest he was using his mobile to either instigate a 'Pair Quality Test', which is what triggers the 'Remote Unit Emulatuion' at the Exchange to test towards the engineers hand-held tester.
Or, he may have been performing a 'Fast Test' with his mobile, which triggers another remote exchange test, but is a low-end test compared to the PQT ?.

HTH. 

[tommy45]

Thinking about it now, he probably run the QLT from the my phone, as i recall him muttering something about it being set to  number with withheld by default,

The DS attainable was a little higher, @ 83628kbps yesterday for several hours ,  but the US has increased from 30670kbps

So more or less back to how it was when i started monitoring the connection , still a small degree of  PSTN /xDSL cross over interaction going on though

Thats fantastic news, I am interested in what the BT66 is also the result of the PQT at SSFP ? - Fail - Red, very interesting.

A BT66 is just a weather-proof enclosure, gel-crimped wire joints within.
