funktel FB4 IP TP

IP-DECT Base with PoE and Cat 5/6 for high-performance communication networks

The FB4 IP TP base station enables the implementation of a high-performance DECT/IP communication network according to a wide variety of individual requirements and circumstances. All cordless telephony functions of the central IP telephony system are supported by the base station, while the DECT Controller makes configuring the DECT network a user-friendly and convenient process.

Integrated contacts enable the greatest possible range of technical installations to be connected to the FB4 IP TP. With its DECT messaging information, the FB4 IP TP can be used to relay specified events or conditions of each contact, such as temperature measurement devices, filling-level indicators, door contacts, motion sensors, etc.
