Automatic Login
The Allegra Duplex Portable supports
Automatic Login for EDACS trunked systems.
Wide Area System Scan
The Allegra Duplex Portable supports Wide
Area Roaming. When scanning, there is a
programmable time interval that determines when
the radio starts scanning the next site.
Supervisory Mode
When a Allegra Duplex Portable is
programmed as supervisory, it is capable of
handling all normal supervisory functions.
Programmable Audio/Display
Each EDACS system has a programmable
option to handle display and audio during
emergency conditions. When an emergency
occurs, the display option can be programmed to
hold the display unchanged until the PTT button is
pressed or the emergency is cleared. The audio
option, similarly, causes the radio to remain muted
until PTT is pressed or the emergency is cleared.
Priority System Scan
This option allows the Allegra Duplex
Portable to search for a second operating system
while locked onto the control channel of the
selected system. If a second control channel is
found, the radio switches to that system. The scan
frequency is programmable.
Group Options
Each EDACS trunked system uses a set of
groups. Each set allows for a home Group ID,
Dynamic Regroup/encoding, and Emergency calls.
In addition to each group ID the following options
are supported.
TX Disable-Group Option
This option prevents keying a radio on a
particular group (monitor only).
Rx Disable-Group Option
This option prevents unmuting a radio on a
particular group.
