On 2 August you kindly responded to my query concerning an NTE5 connection using CAT5E which indicated a need for 4 data and 2 phone wires as follows:
I have just spotted this online which indicates that the BT VDSL faceplate has just 2 connections for a hardwired VDSL connection.
I have tried to find something definitive on VDSL wiring but so far have not had any luck.
