* — Enable inbound audio to be repeated to all radios that use the same base station.
* Control events, such as a wireline test, from starting on the other station when a main/alt switchover
occurs.
* Send commands through a tone sequence to reach locations inaccessible by phone lines.
@ — Eliminate echo at the console.
* — Identify conventional resources through Unit ID and meaningful alias names.
* Send paging tones on conventional channels without an external paging encoder.
2 Mark that a conventional channel is involved in a high-priority situation.
* Create communication patchgroups of different system resources.
1.6 TARGETING YOUR COMMUNICATIONS
Utilizing ASTRO 25 Conventional Talkgroups enables a separation of voice communications between multiple
agencies sharing an RF conventional channel.
° Radio Users — Communicate with multiple users and/or agencies privately on a single RF conventional
channel.
* Dispatch Operators — Benefit from a more accurate view of what is happening on the channel for which
they are responsible. Receive and transmit only to their associated user groups (or agencies), enabling
dispatchers to clear their own emergencies without interfering with other +r talkgroups.
Radio users and dispatchers using the same talkgroup can
communicate with each other, while users of other talkgroups on the
same channel cannot hear them.
Voice Selective Call allows you to make a radic call to a specific individual on a digital conventional channel without
involving other members of the user group. The signal from a Voice Selective Call contains a user ID code and only
that user radio un-mutes when the call is received.
Note: Voice Selective Calls are not private calls.
Although only the single user radio un-mutes, other users can listen to the conversation by pressing the monitor
button on their radios, just as they can to hear the conversations of other talkgroups using their channel and
frequency, or through configuration of their squelch mode. The call uses a special type of Push-to-Talk (PTT)
capability initiated only on a transmit-by-transmit basis.
1.7 CONFIGURATING YOUR SYSTEM
The Configuration Manager provides the ASTRO 25 conventional system a single interface to configure consoles,
gateways, subscriber information, channel tables, aliases, and the logging server. The Configuration Manager
maintains data versioning/synchronization and tracks configuration changes through both full and delta downloads
showing progress and history status.
Sometimes the best location for a base station prevents communication by phone lines. In this scenario, the Remote
Access/Remote Transmit Ear and Mouth (E&M) Keying allows a remote console, using either an RF link ora
microwave link, to control the base radio.
Main/Alternate Channel Pairing provides an alternative station interface for a conventional channel. The console
shows one logical control window for the channel, but physically includes a main and an alternative interface.
