1.2. Product Terminology

This manual includes information relevant to those choosing to use a Private

Branch Exchange (PBX) or Key Telephone System (KTS) with a Dialogic

PBX

Integration Board. A PBX is a privately owned, mini version of a telephone

company’s central office (CO) switch. Grouped with PBXs are KTSs, which are

generally smaller versions of a PBX that provide direct access to CO telephone

lines. For simplicity, the term PBX is sometimes used herein to denote a PBX, a

KTS, or both.

In a PBX environment a line from the CO is called a trunk and a phone is called a

line, extension, or station.
