trunk

A communications channel between two points. It usually refers to large-bandwidth telephone channels between switching centers that handle many simultaneous voice and data signals.

A circuit from a user's terminal or PC to a network is more accurately called a line (i.e. T1 line or ISDN line) rather than a trunk, although the terms line, trunk and circuit are often used interchangeably.
