CAT5

[Steven]

Hi, I don't know the newsgroup to use so forgive me.
I am trying to setup my wireless network router. I need to make a CAT5
cable to hook up to my cable modem. The CAT5 connectors (Levitton) have
two diagrams of choice, "A" & "B".
What is the difference between these two? Thanx Steven

The simple answer IFIRC is that it doesn't matter as long as you are
consistent. Use whichever one you wish but make both ends of the cable the
same. The "A" and "B" patterns simply swap the location of pairs from one
location on the RJ-45 to another and as long as the signal can get through
it doesn't really matter which pair it goes through -- the signal can't tell
what color the wires are. The deadly mistake would be to use "A" on one end
and "B" on the other.

Or it might just confuse the situation more...

Uh... I'm assuming that one is straight thru the other is a crossover.
Straight standard vanilla cat5 cable will work fine for connecting;
Modem======Router======NIC
Also it will work fine connecting the other NICs to the router.
Crossover cable is what you need to net 2 NICs directly together.
I understand you can use straight cable to connect between 2
gigabit NICs (forget the feature name) tho I'm not sure if all gigabit
NICs will negotiate that way.
In any case, if you're using the cable for gigabit transfer, you may have
a few other considerations as it uses all 4 twisted pairs so they all
have to be connected

Which of the two (A or B)is straight thru? I need to make one cable and
connect it to a another cable using a female adapter. I need the two cables
together to make a 8' run. Steven

Both

568A/ 568B are just "pair changes" in the cable. Orange and green
"change places" at both ends.

No difference. Your modem should not need a crossover cable. Pick one
standard and use it. Read your manual(s) to see if you need to make a
crossover cable or not.

Howdy!

If both are the same, no difference in performance.

The apparent difference is which color is used for transmit, and
which for receive.

The actual difference is which standards group pushed it away back
when <B-)

I use "B" myself, since that's what I learned. "A" works also. "A"
to "B" is a crossover cable.
