The acronym PABX stands for a Private Automated Branch Exchange. A PABX is a type of telephone network used by call centres and medium-to-large companies. This exchange system provides multiple lines for outside callers to reach staff, as well as numerous external lines for those in the organisation to utilise. With a PABX system, incoming calls to the company, or to a specific extension, are digitally processed and routed through an automatic switchboard. A PABX system is also convenient since most exchanges allow users to simplify internal dialling between company extensions.

Using PABX Voice Modules for Connections

Voice communication systems use PSTN and PABX modules¬†for establishing wiring connections in the office or residence. With traditional PABX and PSTN technology, copper wires carry analogue data. Voice modules come in standard Euro and 6c sizes. In addition to traditional circuit-switched technology, IP and VoIP PABX technology is utilized by companies. With IP PABX, business phone systems are supported by the company’s own data network.
