Recently noticed my line a few Mbits faster so looked at the stats, which I don't normally monitor unless I have line issues.
I'm on a 40/20 product on a Broadcom cabinet with G.INP enabled and was originally synced at around 36-37Mbit on the standard 6dB target, as I'm approx 500M away from the cabinet and my line has some aluminium in it along the way.
Now though I have maxed out DS sync at 39,999 and my SNR is now 4.6dB and the sync has been up now for over 4 days. As I've hit the sync limit for my product, I'm unsure what my target is now set to.
There was no cabinet-wide outage to cause this, as other lines connected to the same cabinet have stayed up for weeks.
