	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. Stan

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: http://www.cabling-design.com/references/pinouts/1000base_t_crossover.shtml Best regards Roman Kitaev, RCDD
