For large scale networks, all of the connections are punched, not crimped. Punching is easy, layout the wires in the slots, then whack 'em with Harris tool. There are also four and eight-gang punches to punch one complete cable at once.

Big networks don't routinely make patch cables, they buy 'em. It's a waste of time, and hand-made cables are more failure-prone than (quality) manufactured ones. They also come out of the bag/box pre-certified/qualified ... random testing should still be done, and any cable thats kinked, twisted, or shows other signs of stress should be re-tested/re-certified.

A few dropped packets on a game net is no big deal, wen the CEO can't get his stock ticker, THAT"S a big deal.......

Actually the order he specified is incorrect for 568A. His order is 568B, which you should avoid using in your home.

568A is White Green/Green/White Orange/Blue/White Blue/Orange/White Brown/Brown.

568B is White Orange/Orange/White Green/Blue/White Blue/Green/White Brown/Brown.

If you wire up with 568A, you can use the same port for either a 2 line phone system or Ethernet. The Ethernet will use pins 1,2,3,6 and the phone system will use line one on pins 4,5 and line two on pins 3,6. The standard for phone wire hookups in a 4 pair line is BLUE, ORANGE, GREEN, BROWN. So you want line 2 to be ORANGE, which it wouldn't be if you use the 568B standard.


It doesn't really matter if you don't want to worry about a 2 line phone system, but to be technically correct you should wire it via 568A.

It would be improper and out of spec to run phone and Ethernet (or other networking) on the same line. From panel-to-panel (no punchdown blocks) whether 568A or 568B is used would make no difference.

If there's a possibility that cable could be used for phone or data (or video, audio, RF, 5250, 3270, etc) ...it's going to be terminated in a panel. To patch a phone into that cable, there'd be a 110 block terminating the inbound lines, with a 110-to-RJ jumper to cross-connect it into the panel (substitute "66" for the "110" if that's the system you use).

I've never heard anything indicating that it'd be improper to use 568b in the home. That doesn't necessarily mean that it ain't so, but with the crowd I used to hang out with, I think I'd have heard something about it.

You were right about the 568A / B correction to Viper though ... my brain was thinkin' one thing and my finners was typing another...

did you twist it at the ends? Crosstalk can affect speed.
