Just got off the phone with my contact at the CEO's office, he has finally managed to spot the upstream SNR/noise issue on his system which is causing the modulation to revert to QPSK instead of Qam16, so I asked "shouldn't it be classed as an outage then if the upstream does this"(as I vaguely recollect Igni quoting it should do), to which he agreed it should be so fingers crossed investigations may start to finally uncover the cause.

Its probably not going to be an easy fix though but there maybe a shimmer of light at the end of the tunnel, I'm not getting a semi on just yet though.

Maybe one of the more knowledgeable can explain how QPSK modulation would/could go undetected on the docsis 3 platform?

You watch this will all get sorted just in time for Sky to install their BB on the 14th of this month
