when E&M signaling is configured on digital interface like the VWIC is, 2 or 4 wires operation is not applicable because there are no wires at all, and reported only for compatibility with the analog E&M card.

Consequently, you cannot configure that and it will not make any difference to effect of the connection.

Please rate post if it helps!
