1.7.1 ASTRO 25 Conventional Base Radio/Receiver
Each conventional base radio/receiver 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 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.
For information about conventional functions and topologies supported by the base radio/receiver, see the
Conventional Operations
manual. The device can be IP managed while using the 4-wire/V.24 interface
for channel traffic.
A base radio/receiver can be implemented as a QUANTAR

replacement within an ASTRO
®
3.1
conventional system. The implementation details can be found in the
Quick Guide for Replacing a
Conventional QUANTAR with a GTR 8000 Base Radio
manual.
