Business Telephone Systems Overview Business telephone systems are multiple line telephone systems used in business environments. They could be key systems for small scale operations or hybrid systems; or PBX (Private Branch Exchange) systems that are meant for large scale operations or the more recent VoIP systems. In a key system, a central user can look at and control calls directly and manually with the use of lighted line buttons. The operations of PBX are comparable to the usual public telephone system. In this system, the calls are automatically connected to the dialed numbers. PBX systems are also referred to as PABX (Private Automatic Branch Exchange) and EPABX (Electronic Private Automatic Branch Exchange). They are in general used when an office or business needs a dedicated telephone exchange. PBXs share the same technology as that of the central office telephone systems. Some complex and large PBXs have more capability and features when compared to public systems. Less
