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.
