8 - 64 Extensions - BP50
BusinessPhone 50
BusinessPhone 50 central system is a single compact wall cabinet with five board slots, that can cater for between eight and 64 extensions. The cabinet has a built-in switched-mode power supply, with the option of an external battery back-up unit or alternative DC power supply. BusinessPhone 50 system is particularly cost-effective for small offices - a multi-function board that combines trunk and extension interfaces with voice processing and messaging functions means only two boards are needed to build a fully featured business telephone system, leaving three slots free to add more capacity or additional functionality.
