Introduction and Scope

Project 25 digital radio systems will optionally support a standardized set of data communications services. This document provides a detailed specification of the circuit data communication services such that, where these data services are enabled, data connectivity will operate in accordance with the following goals:

• Through any Project 25 radio

• Across any Project 25 digital radio system

• Independent of the particular equipment manufacturer

• Adherence to the Common Air Interface

• Independent of trunking or conventional system modes
