Trunk

 

the highly developed stem of ligneous plants, which is substantially thicker and taller than lateral branches. In trees with monopodial branching the trunk is the main axis that develops from the growing point of the sprout. In trees with sympodial branching the trunk is formed from successive secondary axes.

What does it mean when you dream about a trunk?

The trunk of a tree may represent one’s inner sense of well-being and personality. A thick bark over a large, hefty trunk denotes a strong, rugged, and durable person. A thin, narrow, bark-free tree trunk suggests a highly sensitive but wiry individual. If the trunk is the long nose of an elephant, the dreamer may have a strong “nose for the news” and a very good memory. Alternatively an elephant’s trunk may have a phallic and sexual meaning. Finally, a trunk in the sense of an old-fashioned storage case may reveal the old memories and secrets to which the dreamer is clinging.

trunk

A shared communications channel between two points. Coined by the telephone industry, a trunk typically refers to a high-bandwidth, fiber-optic line between switching centers (central offices). Telephone trunks handle thousands of simultaneous voice and data signals, whereas telephone "lines" are the wires from the central office to the customer.

The term migrated to the information networking industry and may refer to a high-speed or medium-speed channel for data packets.

SIP Trunks
With the advent of voice over IP (VoIP), a SIP trunk is assigned by a SIP provider to a customer, and a single trunk supports one or more telephone numbers (see SIP trunking). See central office.
