The NXU-2A Network Extension Unit uses JPS’ proprietary Radio over Internet Protocol (RoIP) technology to transfer digital voice and serial data. It is optimized for use with radios, radio communication consoles, and other JPS products such as the ACU product line. The device features a variety of codecs, allowing audio links to be configured for the optimal combination of bandwidth and signal quality. Provides a low cost, flexible method for extending radio communications over existing network infrastructure; eliminating the need for leased lines and microwave sites.
The NXU-2A’s ability to delay TX and RX audio is ideal for trunking applications where extra delay may be required. The NXU-2A’s added ability to support multicast Internet protocol (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.
The NXU-2A’s additional hardware offerings include VMR and a “restore to factory defaults” setting. VMR, as with carrier operated relay (COR) and voice operated transmit (VOX) capabilities, determines when a radio’s squelch function is active. The ability to reset the NXU-2A to a well-defined factory default state overcomes the problem of unknown or forgotten IP addresses.
