 Gigabit cross-over cables
Could you share more insight on the topic of gigabit cross-over cables or point me in the right direction for sort of online documentation about it.

I have asked the tech-supports from several sources including 3Com and BlackBox on it and have not gotten a definitive answer.

With Gigibit Ethernet, doesn't all pair have full-duplex bi-directional transmission? With that in mind, if the hardware, being the gigabit switch, which should have the controllers built in to manage the flow of data, would a regular 10/100Base cross-over cable be sufficient??

Any insight you might have on this topic would be greatly appreciate.

Thank you very much.

Hi, Stan!

No, because of 4-pair transmission, normal 10/100-Base-T crossover cords will not work.

You will find information on 1000Base-T cross-over cord at this link:
