VoIP extension

The NXU-2 is a general-purpose standalone VoIP extension for analog radios using radio over internet protocol to send and receive digital voice audio.

The device can be set up as a server or a client depending on system needs. RS232 connection allows for different baud rates between the server and client.

The device monitors its network connection and adjusts its parameters automatically to provide optimum performance under varying network conditions and provides a number of different voice compression settings to accommodate a wide range of applications from voice only to voice plus tone signalling.

Advantages include: enables flexible and low-cost radio communications network; eliminates lease lines and microwave links; multiplexes voice audio and data over a standard ethernet network; eliminates the requirements for pilot tones and other in-band signalling; facilitates centralised control of a communications network from a single PC; and I/O remote site monitoring.
