@ Ruant,
Thanks for your comments although we believe this is very much a network / MSAN difficulty, but time will eventually tell.

@ Everyone
As the Plusnet member centre is down at present I thought I would add some detail here.
Yesterday we had an unexpected visit from one of our resident BT Openreach engineers who came to fix an unknown fault.
Sadly he was unaware of anything to do with the L&S !
He tested the line resulting in NFF using his JDSU.
Meanwhile this morning's 06:00 log shows these figures which are unstable and have deteriorated overnight.
Status: Showtime
Retrain Reason: 2
Max: Upstream rate = 429 Kbps, Downstream rate = 18768 Kbps
Path: 0, Upstream rate = 391 Kbps, Downstream rate = 15847 Kbps
Discovery Phase (Initial) Band Plan
US: (0,95) (880,1195) (1984,2771)
DS: (32,859) (1216,1959) (2792,4083)
Medley Phase (Final) Band Plan
US: (0,95) (880,1195)

VDSL Port Details Upstream Downstream
Attainable Net Data Rate: 429 kbps 18768 kbps
Actual Aggregate Tx Power: 4.6 dBm 10.9 dBm
============================================================================
VDSL Band Status U0 U1 U2 U3 D1 D2 D3
Line Attenuation(dB): 8.1 67.4 62.6 N/A 27.5 0.1 0.1
Signal Attenuation(dB): 8.1 64.3 N/A N/A 27.5 N/A N/A
SNR Margin(dB): 6.6 6.0 N/A N/A 6.4 N/A N/A
TX Power(dBm): 2.0 1.1 N/A N/A 11.0 N/A N/A
However I am relieved to say we have a red worm BT speed test (see picture below) which clearly indicates to all that we STILL have a serious fault to cure.
The next problem will be to get a suitably qualified and powerful PlusNet person to take ownership and resolve the problem with similarly qualified BT Openreach personell, hopefully once and for all.
Kind regards,
Walter
