I found this great tool DMT which will display the noise profile on my line from stats on the router.
With all internal phone wiring disconnected i get this view...
Can anyone tell me if I should be logging a call with Telecom to look connection? Are the gaps to be expected?
Downstream varies between 3 and 4Mbs with the new device and around 5Mbs with the old 604T.
Thanks Quentin.

Here's another view working through my house wiring, I can see it's not optimal....
