Yes, a HR would manifest itself on the router as a higher-than-usual attenuation. Experience shows me that a HR will fluctuate, and as such your attenuation should ??

No, the circuit will probably not be reset if it's a voice fault ...... not unless the attending engineer is also broadband savvy and performs one as a matter of course ?? It is not in the remit of a voice fault to perform a reset.

 :)

Actually no, my attenuation seems pretty stable, at least according to my HG612. It may move by about 0.1db occasionally but its pretty minimal. I'm gonna ping Plusnet and see if they have the engineers notes yet and push for them to get BTO to reset the profile once the HR fault has been sorted.

The HR must be pretty miniscule, if at all there ??? Your post states that the engineer who has already visited said there was another "Possible HR". This could indicate that the TDR function we use to identify HR's, has actually shown a cable joint where the poundage (size) of the two cables changes from, for example, 0.4 Ali to 0.5 Cu ??

Of course I've no idea what the engineer on-site has seen, so have to trust in his experience.  :)

He didnt give much detail to be honest, he said they fixed one potential problem on the pole but the quiet line test and his kit was still showing another issue which he said need to be dealt with by the UG team. There were a few guys here and they seemed to know what they were doing, just have to wait and see what happens I guess.

No dropouts since they left, which is already an improvement.

To have a synchronisation speed of ~65 Mbps at 360 metres from the cabinet is approximately what I would expect to obtain -- depending upon the condition of the cabling, the joints and the what-not.  :)
