Removed the original telephone jack/plate. I removed the plate and jack, unscrewed the Blue and Orange pairs from the telephone module (which used the old Red/Green/Black/Yellow colors) and replaced with 'snap-in' jack, and added an Ethernet 'snap-in' jack, then mounted the new wallplate:

Telephone jack with 4 conductors on RJ25 (6P6C):

PIN	FUNCTION	COLOR	OLD-STYLE
1	(n/c)
2	Line2 Ring	Orange	Yellow
3	Line1 Ring	Blue	Red
4	Line1 Tip	Blue/White	Green
5	Line2 Tip	Orange/White	Black
6	(n/c)

Shoud be:

PIN	FUNCTION	COLOR	OLD-STYLE
1	(n/c)
2	Line2 Tip	Orange/White	Black
3	Line1 Ring	Blue	Red
4	Line1 Tip	Blue/White	Green
5	Line2 Ring	Orange	Yellow
6	(n/c)

Ethernet jack with 4 conductors on RJ45 (which limits speeds to FastEthernet 100Mbps; 8 conductors needed for Gigabit Ethernet). Because the Orange pair is already committed to the USOC phone standard, the Brown pair is used in place of the Orange:

PIN	FUNCTION	COLOR
1	TX+	Green/White
2	TX–	Green
3	RX+	Brown/White
4	(n/c)
5	(n/c)
6	RX–	Brown
7	(n/c)
8	(n/c)
