Terminating Cat5e T568A or T568B?

[Praetor]

I'm into my 2nd week in our new house. It was already wired using Cat5 for the phone. As I'm not planning on having a land line, I opted to use the jacks for the data network.

I've terminated all 9 jacks using the T568A standard, both at the keystone and the RJ-45 end. As I was looking at some pre-made jumpers, I noticed that they were terminated using T568B.

Do I need to go around and change the 18 (!) ends or can I leave those with "A" and connect with standard jumpers?

If it makes a difference, I'm running a giga network with at least 3 machines in different parts of the house.

You're probably OK. US uses 568b.

As far as plugging 568a jumpers into 568b jacks or vice-versa, you're fine (assuming you did your terminations properly & to spec).

Where you *might* have an issue, since you mentioned that these used to be phone lines, is that many phone lines are terminated in a daisy chain (jack to jack to jack, or all in parallel) ... and that's not good for any flavor of Ethernet over UTP / Cat{3,4,5,5e,6,6a}.

If you know that each room jack terminates back at the central closet, then you're likely to be golden ... if you don't know for sure, it'd be worthwhile to trace it out before putting it into "production," if only to save you some head scratching and frustration.

Good Luck

This house is only 2.5 years old, so I lucked out there. Each line is home run to the basement. I've already toned out and labeled each line and even printed out a map of the house so future owners will be able to translate my thinking. 🙂

Thank you both for your insight. I'll be lighting it up over the weekend and find out what happens.
