Hey folk,

Figure someone here may have a better explanation to the cause of this. I'm assuming a loose joint?

What happens is, at the peak of day when it gets hot.... Line gets Frequent disconnections and slow speed. This lasts until a phonecall is made or received.

Afterwhich, slow speed stays till a reboot (line itself stops sh!tting the bed).

Reason I'm asking is, i suspect there may be something categorically i could build out from this... but it's also affected my line and i'd prefer not to further work with the 'ninjas'....

I have not pulled apart ETP and checked, Splitter was replaced a few months back.

As you figured, probably a corroded joint that has mechanical movement with heat expansion - you know the drill, isolate at the ETP to see if it's inside the premises, and flick it back to the ISP if not.

Suppose i'll have to work from home one day and re-splice things!

I am incredibly surprised by now you have not found a way to get VDSL from the front of your driveway especially with excellent examples on this forum of people doing just that.

Like geez, you've had almost 4 years... https://www.geekzone.co.nz/forums.asp?ForumId=49&TopicId=151292

oh. i have a VDSL link aswell.

this is my low latency (iknow... but i prefer the speed routing of my non vocus link)

but yes, i haven't done that project. Other things have been more occupying... I totally don't have all the equipment in a pile in the room!

I would say just standard high-resistance/bad joint. Quick little look with a Dynatel, fix her up, and on your way.

Maybe go through your local stuff up to the DP and then log a fault from there. But likely just been disturbed down the road in another DP.

...assume this isn't a Spark line so you can't apply some 'spark magic' to it to diagnose?

It would have had the magic fairy dust sprinkled on it already if it was a Spark line!

Nope, not a spark line.

touching my own line would be a no-no really.

Yesterday it was a bit annoying, reboot and back to normal. today seems to be worse...

literally just got home, so no pulling apart tonight, might recrimp tomorrow morning before work though. Past there i'll have a drink with the local chorus tech i suppose ;)

testing was looking at a variable high resistance link indeed, in that 'Good line' area though which is a PITA to get past tier 1...

pulled out my box this morning, open up the ETP and i'm sitting there going wtf?... why did i double crimp the line end?... It didn't need extending.

Looked ok, Gel didn't look too bad.

time for work, in the 5 mins it took to post this attainable jitter is looking better yay.

I suspected it was a HR join somewhere, just wanted a little more logical explanation so i could deep dive later ;)

on the upside, Looks like i won't have to have someone poke around? yay....

Isn't exactly a hot day..... but considering things haven't missed a beat... might be looking good.

Atleast this post goes to show, even when we may be well regarded, knowledgeable and feel like our wiring is perfect, faults can arise.

sadly yes, ddDLM pulled the upstream snr back straight away.
