This network-capable device is powered via the LAN cable using Power over Ethernet (PoE). The main advantage of PoE is that you do not need a power supply cable.

You save installation costs and can enhance the reliability of connected devices by using a central uninterruptible power supply (UPS) if desired.

By transmitting voice and control information over a data network, computers, IP telephony specialized terminal devices, and traditional phones connect with each other. IP technology allows you to implement telephone services on Internet Protocol infrastructure, thereby replacing your conventional telephone technology, including ISDN and all components. The use of IP telephony enables cost reduction through a uniformly operated network. The transition can also be realized as a long-lasting, gradual shift - referred to as "soft migration.".
