TSNR = Target SNR Margin! TSNRM

Are you talking about the two capped products? I.e.O2 Standard (legacy), and Be Value in both legacy and current versions?
Or something else, such as day-to-day running, where the margin varies as expected.
The 0.5dB immediately after sync I agrre is odd, bur seems to be a differnet, though perhaps related, issue.
What's TSNR? Or am I just having a brain failure? T SNR = target SNR,
I was referring to both the legacy o2 packages and the be unlimited package,
but even if gdmt mode is forced there still is no spare margin visible , and that maxes out at around 12mbit which is a little high

the package is irreverent really, but should be more obvious if someone is on the capped @12mbit value product ,if their line can support a higher sync, but truth is only the tsnr is set to shows when is should show a higher (spare snr)

Why?
Because it has not been used for the sync and is "spare" and for our info too, so why not ?

When a line is syncing at the maximum speed on a capped product, and has an unnecessarily high SNR margin, the DSLAM can reduce downstream output power to minimise crosstalk interfering with other peoples lines. This is what appears to have happened with the stats that XRaySpeX has provided.

So why the diff. between the Orange & O2 behaviour? They were both LLU ADSL2+.

Because how you can configure a DSLAM is very varied
