What problems are we likely to encounter with this setup? Our normal wiring method is one jack one cable….. A.

I wouldn’t like to speculate on whether it will run at higher speeds because that is dependent on the quality of the installation and the amount of network traffic. If the installation was originally wired for Token Ring then it will use pins 3, 4, 5 & 6 which will not work with Ethernet. Crosstalk could be an issue if the pairs have been split between outlets and/or between pins on the jack, (pins 1 & 2 should be a
