Conference Link2

To build a custom Conference Link2 cable, use shielded CAT5e, or better, and terminate both end
connectors, P1 and P2, with standard 8P8C plugs (for example, RJ45) using the wiring connections shown
in the following figure. The maximum length for this cable is 100 feet (30 m). Note that this cable provides
a cross-over connection between pins 1 and 2 and pins 5 and 6.
