This document is intended to clarify key aspects of the operation of Project 25 subscriber, base, and repeater station equipment in the interests of conformance.

It includes a set of PCP items or procedures for basic conventional operation as follows:

PCP 1.1 – Voice Calls

• PCP 1.1.1 – Group Call via Repeater Operation

• PCP 1.1.2 – Individual Call via Repeater Operation

• PCP 1.1.3 – Group Call Direct Operation

• PCP 1.1.4 – Individual Call Direct Operation

It is consistent with other pertinent APCO Project 25 Conformance Profiles, namely:

Project 25 Conformance Profile – Level 2 (Advanced Conventional Operation)

Project 25 Conformance Profile – Level 3 (Basic Trunking Operation)

Project 25 Conformance Profile – Level 4 (Advanced Trunking Operation)

Project 25 Conformance Profile – Level 5 (Phase II Trunking Operation)

This document is primarily aimed at manufacturers and conformance test facilities to serve as a standard reference of conformant air interface signaling, as a means of assisting manufacturers in the development of conformant Project 25 equipment. It also defines a framework against which manufacturers may describe the conformant behavior of their Project 25 products.

It is not designed as a functional interoperability test suite for end users, for which readers are referred to [7].

This document assumes an audience familiar with terms and definitions contained in the APCO P25 standards.
