The NXU-2B is a general purpose stand-alone device that interfaces full duplex audio, one RS-232 port and four status bits onto an Ethernet network. It is optimized for use with radios, radio communication consoles, and other JPS products such as the ACU product line. The NXU-2B features a variety of codecs, allowing audio links to be configured for the optimal combination of bandwidth and signal quality. It provides a low cost, flexible method for extending radio communications over existing network infrastructure; eliminating the need for leased lines and microwave sites.
A pair of NXU-2Bs can form a simple system that creates a transparent communications link between the two. One of a pair of units is set up as the server, the other as the client. The audio, RS-232, and status bits appear to be simply extended between the two devices.
The NXU-2B features remotely adjustable advanced optimization settings, including audio level, audio delay, and voice recognition. The NXU-2B’s ability to delay TX and RX audio is ideal for trunking applications where extra delay may be required. Voice recognition (VMR), as with voice operated transmit (VOX), allows the NXU-2B to determine when a radio or other device is receiving with no squelch condition.
The NXU-2B’s ability to support multicast IP is optimal for customers who use multiple NXUs. Multicast IP reduces the amount of network traffic, which ensures that each unit in the multicast group will receive communication.
