Thanks NS, thought BT would request a reset  ???

I'll ask them for an engineer to check the BB as it's still the same, if not a little worse than before.

Nuts how many different engineers only deal with certain parts, does makes things more complicated/time consuming going back and forth ::)

I agree, it does seem to be a convoluted process.  ;)

Try thinking about it using a medical analogy. You go into hospital for brain surgery. The only surgeon currently available specialises in orthopaedics. Does the orthopaedologist operate on your brain?  :-\  :no:

Tell me about it  :hmm:

That's a similar analogy to what I use, Mr Cat. Not many are completely fully-skilled, and because the single-skilled person (Frames or CAL/OMI) get paid exactly the same as someone with the whole lot (Frames, CAL/OMI, UG, ADSL, VDSL, Managed Installs, Hot-sites, DACS, SL&G, Flat-Roof, Private Wires, ISDN2/ISDN30) , then why would anybody but a fool* want to get up-skilled ??

This is the reason there is so much confusion with the EU and who does what ?

*See me ...  :'( ??? :(

I still think since the OR engineer called this in as a battery fault on the 16th of Feb and the waterlogged undergrould cable has been fixed within two days that's excellent service from openreach either way you look at it  ;D

I could answer that Blacksheep it's upto the individual some enjoy the job and some just see it as only a job, when you like your job it becomes a hobby and you want to know all there is about it and money does not come into the equation, yes it's nice to get paid for a job you love that's a bonus  ;)

But if you were just one of the single-skilled technicians then you wouldn't be much use to us here -- except in the area of that one speciality, say, DACS!  ;D

I appreciate your comments guys, and no doubt as with yourselves, a thirst for learning and a want to 'know' your chosen profession ........ is the reason most engineers volunteered to upgrade a couple of decades ago. The then-promise of extra bunce in ones pay-packet, also helped with the leverage.  ;)
Alas, (as mooted) the cash never appeared but still some of us kept taking on more skills such as Broadband, Hot-Sites, Local-Line Integrity ...... basically skills that you have to apply yourself, more than you would stapling a 4-wire internal cable around a skirting board.  :) .......... and yes, I do get far more enjoyment out of those tasks on a faulting basis.

I seem to have wandered OT slightly, just wanted to put it out there why some engineers and some tasks will not see VDSL port-resets take place.

That SNRM graph still is showing an "unhappy" circuit. The QLN graph seems to be "lifted" as a whole (I wonder if there still is mains hum present) and the bit loading graph shows some higher tones unable to be used.  :-\

Of the four, only the Hlog graph "looks good".

As I am not a user of a VDSL2 circuit, I would prefer to wait and see what others think . . .

Thanks BK!

Things do look a lot worse, i'm thinking there's still a fault with the actual copper pair as we're talking water ingress in an inspection hole, i'm a multskilled engineer myself in hi-tech security/ip systems and know from experience water is the worst thing that can happen to a joint/cable as it soaks up the line inside and out degrading all parts especially the copper wire (black copper anyone  :no:).

When I got in last night and started the stats, the fluctuation on D/U was minimal, then later in the evening we got heavy rain/hale on off during most of the night and the results are as posted above.

Looks like this is going to be a long winded process, I bet when the BB eng finally comes he will find a faultly line as it always has been in the past, why BT won't arrange a proper rewire and get the job done and dusted ??? probably cost.

Although doing a quiet line test it seems all good, maybe the other guy's can shed some light as I don't know if a stuck DLM can produce these results or it is a continuing cable fault, still can't do a "Full" test using the BTwholesale speed test always comes back with an error occurred and only a basic speed result?
