OK, just got someone at work to refresh my port,
Service profile reset from :
Service Profile Name: VDSL2-DLM-2
to:
Service Profile Name: EUBAV-I-FSFS
then to:
Service Profile Name: EUBAV-F-FSFS
All in about 4 hours, so the learning process after a port refresh is fairly quick! Not sure why it shows EUBA and not VDSL for the better profiles. Checked a few other lines and theirs was the same.
I'm looking at that -I- and -F- suspiciously... DLM adjusts interleaving automatically (unless chorus have changed their profile naming schema for VDSL)?
