Dear Michael,
I am not really sure what you are referring to as "Non-standard straight" patch cords but I am going to guess that you mean a cable that is pinned with Wh/Bl on pin 1; Bl/Wh on pin 2; etc.
While electrons are color-blind, what is most important here is maintaining pair continuity. Pairs of cable are needed as follows for the 8 pin modular plug for networks.
Pins 1 & 2
Pins 3 & 6
Pins 4 & 5
Pins 7 & 8
If I continued with the original assumption of your "Non-standard straight" the 2nd and 3rd pairs would then be split which would have a very detrimental effect on the network signal, if it works at all. I see no advantage to this wiring scheme as it is not designed to work with any system or protocol.
Sincerely,
Joseph Golan, RCDD
