A communications circuit that interconnects switches. As such, multiple users and multiple transmissions can share a trunk on a pooled basis, with contention for trunk access managed by an intelligent switching device. There are many types of trunks. Tie trunks connect Private Branch Exchange (PBX) switches in a private network, Central Office Exchange (COE) trunks connect PBXs to telephone company central office exchange switches, and interoffice trunks interconnect central office exchange switches. Trunks traditionally are directional in nature, with the options being one-way outgoing (originating), one-way incoming (terminating), or two-way (combination).
