Some context, recently had vdsl activated at new (1960s) property. Probably about 800M away from the cabinet. The disconnects were so bad that DLM lowered my profile to a point where I dipped below the minimum guaranteed sync and I called my provider Vodafone who arranged an openreach engineer to come out. I wasn't there when he visited, but apparently he found a fault and replaced some cable possibly between some manholes between my and my neighbours property.
'Someone I know' also replaced the old oval shaped block terminal from the incoming cable and the master socket to a 2019 BT Openreach Telephone Master Socket NTE5c MK2 & VDSL/ADSL Faceplate MK4 which I purchased from eBay. This was installed before vdsl was activated.
So using the new NTE5c and MK4 Faceplate, the Vodafone router syncs reasonably well, but disconnects ~every hour or so. Unclipping the Faceplate and using an ADSL Nation XF-1e dongle style filter in the NTE5c, the disconnects seem to stop completely.
Could the Mk4 be faulty, or perhaps the XF-1e is coping better with my line conditions? My stats are (with the XF-1e):
