Recurring upload modulation issue

Hi,

We're experiencing an ongoing issue with upload modulation being inconsistent and causing mild to severe packet loss.

Engineers have been out to the green cabinet twice in two months. The latest being on the 26th when there was severe packet loss. After that fix there has been milder interruption on one upload channel and we're counting the days until it rears its head again.
