I noticed that my line re-synced at around 3.30am, which with my current line problems isn't that uncommon. However, upstream SNRM is at around 7dB (usually between 5 and 6dB) and I'm getting fully line rate on the upstream too, which is getting more usual but still not quite the norm. After a bit of poking around, I've just twigged that G.INP has been enabled on the upstream. My understanding was that OR had disabled G.INP on the upstream due to incompatibility with some modems?! So have they solved that now?
After all the aggro I've had with my line over the last 2 months, this was a very pleasant surprise.
