DSLAM adjustment this morning -SNR 5.3 although along with it comes the Re-tx high Inprein 1.00 , so will manually cap once at 3.3 to get that little DS Re-tx low back.
Yes, more or less my experience on Zen migration, likely more of a product of DLM reset which would have occured with migration to any ISP.
Had expected your line would end up on DS G.Inp re-tx high profile if not on the initial DLM reset then at one of the later DS SNRM downward migration steps.
Still, easily fixed by modem speed capping once 3dB DS SNRM is achieved, have found that once re-tx low profile is achieved there is greater tolerance to DS FEC error rate which is believed to be one of the factors monitored by DLM governing re-tx profile selection, I was able to increase modem caps to max available on my line with DS FEC error rates averaging between 10,000 to 12,000 "
FEC errors/hour, daily rate" as monitored by DSLStats.
