I'm highly suspicious that the OR engineer who visited you (the afternoon before a bank holiday) said that there was an issue at the DSLAM... and here we are bank holiday not yet over and its been closed. I do not see anyway where they over the bank holiday weekend would have swapped out linecards. More likely your 'fault' got closed as he walked away and its taken a couple of days for this info to filter back to Plusnet and then back to you.
That is one of my points.
Reading the reply from Plusnet they have been told.
Engineer Notes
2015-04-02 15:40:36 : 02/04/2015 15:40:32- Notes - DCOE DONE LIFT AND SHIFT BUT PORT STILL DROPPING AND SLOWING DOWN TOLD TO SEND BACK INCOMPLETE FOR DIAGNOSTIC TEST E/U MOBILE 0744949
DCOE: The woosh test is a pass no fault found, an engineer has today done a lift and shift and the line is now in full sync at speeds of 61.5 down and 20 up which are slightly exceeding the predicted 54.5 down and 15.7 up. The line may needsome time to settle but i am passing it back to the cp as OK RWT by DT.
Summary
line not banded, no errors, REIN and Crosstalk not detected. sync above estimate, updated WP profile.
The
bold is my emphasis.
This is a line which before being touched was at 66999/20000 G.INP On & was being investigated for a fault.
Suddenly the line is predicted to be 54.5/15.7 so 61.5/20 is a win. (How convenient just the sync I got after the 1st fix by the 2nd Engineer!!!)
End of Game, pack up & go home
As you rightly say nothing has happened over the Easter period, the DSLAM fault is 'no-more' and I am worse off.
This is the reason I am doing 'Hulk' impressions. (I am running out of Shirts
)
Someone has simply cleared all the faults associated with the call on the back of a woosh test.
The engineer had said the
line tested good but had random drops so the Woosh test proves nothing.
I am also assuming the Woosh test is remotely done so not even testing at the DSLAM itself which is where the problem was reported.
I assert Remote Diagnostics are NOT 100% fool proof.
Anyone who wants to prove me wrong is welcome to do so.
