IP-224 is the IP radio gateway at the heart of the Telex Radio Dispatch System.
Based upon the Linux operating system, the IP-224 provides an extremely reliable means of remote-controlling two audio devices. The IP-224 can be easily configured to work with both digital and analog consoles, and it performs a wide variety of other tasks related to using radios on a digital network, including state-of-the-art system diagnostics, SNMP, redundant Ethernet connections and a wide range of advanced radio interfaces such as P25, NXDN, MOTOTRBO, DMR, and TETRA.
