In either 568A or 568B, pin 4 is Blue (Ring) and pin 5 (Tip) is Blue/White.

I'm not sure you are asking the right question.

Are you using the telephone wire for Ethernet? Tip and ring refer to pairs of wires - transmit tip and transmit ring and receive tip and receive ring etc. Standard telephone wire (typically cat 3) will not run 100MBPS ethernet that is typical today.

No, I'm using cat5 wire and eight pin jacks for telephone and 100baseT Ethernet. Using them for the phone just because I have them.

I just wasn't sure which pins matched up with telephone tip and ring in the T568A configuration.

Thanks....
