network cabling cat 5e t568 A or B?
so I live in a room downstairs at the moment and I have ethernet cable from my room to the router which is the room upstairs.
I have crimped one end with t568 B standard ( i did exactly what I saw from a store made cat5)
Now I assume, since I can't remember from the cabling class i took, that the other end has to b "B" right?
(I have more to talk about, but that's what I need answered first to continue discussion)
:)
thanks!

thanks Gary.
prashsax,
I found that link last night :). My question is now...after I make both ends or make one end to a wall jack (B) and I don't get anything...what might i do next?

Do you get link lights? What are you connecting on both ends?
You may need a Crossover depending on the end devices. If they are the same type (PC-PC, Switch-Switch, etc..) you need a Crossover cable.
Normally you would wire the wall jack straight through and use a crossover on either end but that's up to you.

A straight cable should have same kind of connection at both ends.
If you do not get any lights after connecting the cable then you need to check the crimping. It is possible that the wire are not cimped properly to RJ45.
Also, if you are not using any switch or hub in between two machines, then you require cross cable.
For cross cable just interchange 1 with 3 and 2 with 6 on both ends.

the wall ethernet jack is made by Leviton. Its got either A or B. The cat5 cable I crimped is how I followed a standard store bought cable. which by that diagram in the link shows B. Thats what I'm using on the newly crimped end. But you say I may need to try crossover...which would be to A?
I am getting no lights on the router (upstairs) when I plug the cable to the wall jack to my desktop (downstairs).
i have a switch, but am not going to add it until windows recognizes a link ya know?

It sounds like you have a problem in your cabling. As far as what you need where it's this
Router (w/builtin switch such as Linksys) > PC = Straight
Router > Switch = Crossover (or use a straigh cable to the uplink port which does the crossover for you)
Switch > PC = Straight
When you make your own connections you have to be sure not to split pairs. That is using the white from one pair with a different color. When you strip it back, you need to make sure that the pairs stay together. It's possible to lose track if you untwist it too much. (Note: for Cat5 connection you need to maintain the twists as close as possible to the connector ~1/4" max)
Sorry for the confusion about A/B and crossovers. Normally you would use one standard throughout. It just so happens that if you mix the two, you end up with a crossover, which may be desirable at times.
Do you have any way to test the cable? An Ohm or continuity checker?

I don't have one, but I was going to have more time tonight to check it out. I will update what I've tried tonight.

To make sure I was crimping and making the wires correctly I took a store made cable and cut the end and remade them. AFter I finished I tested it and it worked great. Then i went back upstairs to the router where the cable was and made a new crimp and then went back downstairs to my desktop and pulled the cable out of the wall and crimped that end and then plugged it in. Worked.
I have a problem though. I had to cut through a line that was supposed to be continuous and not just stop at my desktop. The wall jack I have from Leviton I tried to terminate, but never got anything to work. The wall jack is t568 A or B. I placed the wires as B in the jack and never got any connection from the router to the wall jack. SO that is why I did the above. Hence my problem. Without using a switch how can I make it continuous going to my desktop and proceeding on through the house to a different location?
obvserve my explanation :P

Well, the best way would be to put a hub or a switch at the desktop.
An ugly solution without a hub or switch would be to put a second NIC in the desktop and set it up with ICS (Internet Connection Sharing) on the NIC that's connected to the router.
Small Hubs and Switches (4-8ports) are fairly cheap thes days. I would just get another one and use that.

Thanks experts! I will try that splitter from Cyberguys.com or at a local store that has something like it :)
Unless you want a Ethernet Crosover cable. That's what you get if one end is A and the other is B.
