P25 Interfaces
The following figure identifies ten system interfaces in a public safety P25 LMR network. P25 interfaces enable interoperable voice and data communications between and among different public safety agencies. An example is communications between police and firefighters in a particular jurisdiction. A further example is communications among agencies in different jurisdictions, such as when incidents require the response of agencies from two or more jurisdictions. Standardized P25 interfaces are the “glue” enabling interoperable mission-critical communications between and among radios and infrastructure equipment procured from different manufacturers that compose P25 LMR networks.
