Project 25 Documents & Standards Reference
Description and Specification Documents
Two types of documents are used to describe and specify the interface, service, or equipment: one type provides an overview, the other type defines the protocols.
The Overview document — typically a TSB — describes the operation and function associated with a standard, but it does not prescribe a standard. Thus, the overview document is considered informative. The overview document provides background relating to the P25 SoR, shows its relationship to the overall P25 system model, and provides guidance to users, system designers, and manufacturers.
The Protocol documents are considered normative. They provide the required messages, formats, and specifications necessary for the P25 interfaces, services, and equipment to be interoperable and meet the users’ needs.
