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.
In the context of generic data center services, a cross connect typically refers to the patched connectivity between the data center's facilities and the line of demarcation into the building. It would often be the patched connection between your servers and the Internet access or any additional network connectivity.
