Project 25 Documents & Standards Reference

Revised Jan 18, 2012

System Description and Organization

P25 (Project 25) system overview documents describe how the users and manufacturers envision the P25 system, the logical interfaces and services the standards will specify, and the documents needed to completely characterize the P25 Standards Suite. P25 provides this information in TSB (technical service bulletin) overview documents (sometimes referred to as “shell” documents). These documents provide an overview of the entire suite of standards for all interfaces and give a functional description for the current set of CAI (Common Air Interface) features. (Note that the P25 documents suite contains overviews of individual interfaces and services, as well.)
