Switching and Voting Priorities
Run mode
Run mode switching is defined by the following table.
The switching rules are explained as follows:
1. Higher priority streams are listed earlier in the table. Higher priority streams will be
voted in preference to lower priority streams.
2. If the channel group mode is duplex, the base station selects a single inbound source,
and a single outbound source, and sends them to the interfaces as defined in the ta-
ble.
■
Outbound streams are sent to the local RF interface
■
Outbound streams are also sent to the local speaker in simplex mode
■
Inbound streams are sent to the analog line and speaker
■
Inbound streams are also sent to the RF if RF repeat is enabled
3. RF transmitter operation depends on whether repeater transmission is enabled or dis-
abled.
4. Maintainers may put the speaker into RF monitor mode using the control panel. The
behavior of the microphone is independent of the speaker monitor setting.
5. Only streams that originate locally are sent to the channel group (IP network)
6. “Simplex” in the table means that this switching path will occur only if the channel
group is set to simplex. Simplex channel group mode selects the highest priority (ear-
liest in table) stream, and sends it to all the local interfaces.
7. “Repeat” in the table means that this switching path will occur only if RF repeat is
enabled. This may be via configuration or task manager.
