BT Versatility
From Wikipedia, the free encyclopedia
The BT Versatility is a telephone PBX switchboard sold by BT and targeted at small businesses. It is manufactured by Lake Communications in Ireland as the OfficeLink.
It has modular construction allowing a basic setup to be expanded as needed by clipping extra modules onto a backplane
The basic Central Control Unit (CCU) starts off as a 8 extension unit, with either analog POTS lines or ISDN line modules available. There is a serial connection that can be used for call logging and configuration. It can either use standard telephones or proprietary feature phones. A special Door Phone may be added on extension 23 and the system may be connected to an electronic lock relay to allow the door to be opened via a Door Phone call. Any extension may be programmed as a PA (Public Address) speaker.
It is the successor to the BT Pathway also made by Lake Communications, which superseded the BT Inspiration which in turn superseded the BT Revelation.
