Background:
Zen FTTC Unlimited Fibre 2 (80/20 max) connection
Line is connected to an ECI cab
WBMC not Zen backhaul
Usual sync rate of around the mid 60s (68 is about the highest I've seen, disregarding a power cut we had in the area once and my line being one of the first to reconnect and got high 70s for a while until others came back online).
SNR usually around 6 as per normal target
Line is usually very stable, regularly getting over 100 days uptime. DLM has rarely if ever intervened.
Thursday 25th June 2020, the line dropped in the early hours (around 1:00am), and returned at a round sync rate of exactly 67000, and with G.INP enabled for the very first time (so I'm assuming I'm part of the ECI G.INP trial). I noted the very round number sync rate in passing but didn't really think anything of it, being more excited about having G.INP etc.
Today my SNR jumped to above 7dB, in the past if I had this headroom above the 6dB target, I could force a resync and get a higher sync rate, however, doing this today resulted in the exact same round 67000 figure despite the SNR still being above 7dB.
Is this positive proof of being banded / capped?
Would this be something to do with being on the ECI G.INP trial, or is it a separate issue?
Should I bother Zen with it, or, just leave it, don't mess with anything (no more resyncs etc) and and let DLM sort everything out (however long that may be) ?
