Techopedia explains Private Automatic Branch Exchange (PABX)

In PABX, the exchange is owned and managed by the private organization in which it is installed and relies on computer equipment to handle the switching of calls. This is why the system is considered both private and automatic.

With PABX, an operator is only required to supply information and to occasionally manual connections for callers who are unfamiliar with system or the organization.
