Project 25 – Conventional Control Messages
Published By | Publication Date | Number of Pages |
TIA | 2009 | 18 |
This document defines the message formats for the conventional
supplementary data functions. These supplementary data messages are
extensions to the basic Common Air Interface. Conventional systems
for APCO Project 25 are defined to be any non-trunked system which
conforms to the standards and specifications of
[102A] or its subordinate documents, where a
trunked system is defined to include a centralized controller that
assigns requests for service by subscribers to specific radio
channels. Conventional systems therefore do not have a controller
which assigns radio channels in the same sense as defined in
[102AABC-B].
