How to read this

Every construct on the map is compared with every other by the meaning of its definitions, and the closest one is surfaced here. The nearest construct to trunk is stem.

Hold this as a prompt, not a verdict. Two constructs sitting close in meaning is a reason to read them side by side and decide for yourself whether they are one idea under two names. It is not proof that they are. Compare the meanings in the Collider.

Telecommunications

a shared high-capacity link between switching points carrying many connections' combined traffic, instead of a line per call.

A shared high-capacity link between two switching points that carries the combined traffic of many individual connections, rather than one dedicated line per call: exchanges are joined by a bundle of trunks that callers seize in turn, so far fewer circuits are needed than there are potential conversations. Erlang's 1917 Solution of some problems in the theory of probabilities of significance in automatic telephone exchanges worked out how many trunks a group needs to keep the chance of a blocked call low. The referent is an engineered shared link and a unit of network capacity, not a body region, a tree's stem, or an animal's proboscis.[1]
