Crosstalk is a disturbance caused by the electric or magnetic fields of one telecommunication signal affecting a signal in an adjacent circuit. In an telephone circuit, crosstalk can result in your hearing part of a voice conversation from another circuit. The phenomenon that causes crosstalk is called electromagnetic interference (EMI). It can occur in microcircuits within computers and audio equipment as well as within network circuits.
Crosstalk is tested between each possible pair/pair combination in the cable, and is tested both from the main and remote tester units, with the results of each reported separately under the columns MAIN and SR. The Worst Case Value table, to the right, is always blank on patch cord tests.
