The Time-Slot Interchange is a device primarily used in Circuit switching.

Explanation

Circuit switching is a method of communication in which a dedicated communication path (or circuit) is established between two endpoints for the duration of the transmission. In this context, the Time-Slot Interchange allows the efficient rearrangement of time slots in a switch, facilitating the connection between multiple sources and destinations without the need for a physical path. This process is essential in voice communication networks where the time slots allocated to each call can be dynamically rearranged to optimize bandwidth and enhance communication quality.

In contrast, packet switching, which is used in data networks, operates differently. It breaks down data into packets, which are then routed independently to their destination without a dedicated path. Therefore, the best fit for the Time-Slot Interchange's application is in circuit switching.
