HG612, connected to Draytec 2925.
No Powerlines. Straight into latest BT faceplate, no internal wiring. Other devices, another HG612 for my VDSL, UPS, and apart from router and PC nothing.
Sort of what I thought, must be a excahnge / DSLAM issue ? Saw the RFI at 1Khz (tone 230), but its seems minor and the same blip on my VDSL circuit. Last option to tray a different modem, but reluctant as it only happend post voice issues on line (noise followed by no dial tone)
Thanks for thoughts
Tony
