Morphology

PBX = P + B + X

PBX is an initialism (letters stand for separate words) rather than a composition of productive English morphemes, so the letters do not transparently convey the meaning to learners.

Etymology

PBX comes from the phrase private branch exchange, where private means 'for one organisation', branch means 'a part of a company', and exchange means 'a place to switch calls'. So a PBX is a company's own telephone system that switches calls inside the office and connects to the outside.
