Chapter 1: GTR 8000 Base Radio Description
•
A Centralized or Distributed Conventional Architecture, or
®
•
An ASTRO
3.1 Conventional System.
Each conventional base radio uses either:
•
A 2- or 4-wire TRC or 4-wire E&M interface in an analog infrastructure
•
A V.24 interface for digital voice and data traffic to either a Channel Bank, Digital Interface Unit,
Conventional Channel Gateway (CCGW), MLC 8000, or link converter, ASTRO-TAC 3000
Comparator, and an optional 4-wire link for analog voice in a mixed mode configuration
•
An IP interface for digital voice and data traffic to a CCGW or GCM 8000 Comparator.
NOTICE: For information about conventional functions and topologies the base radio supports,
see the Conventional Operations manual. The device can be IP managed while using the 4-
wire/V.24 interface for channel traffic.
NOTICE: A base radio can be implemented as a QUANTAR
3.1 conventional system. The implementation details can be found in the Conventional
QUANTAR Replacement Guide manual.
