Hytera PD78X User Manual

Priority Interrupt
The Priority Interrupt feature allows you to interrupt the
ongoing activities (such as a call, a call hang status, or
remote monitor) on the current channel to free the
channel, so as to initiate a new call or a new data service.
The feature includes Manual Priority Interrupt and Auto
Priority Interrupt.
Manual Priority Interrupt
To manually terminate the ongoing activities, press the
preprogrammed Manual Priority Interrupt key.
Auto Priority Interrupt
Auto Priority Interrupt includes Emergency Priority
Interrupt, Call Back Priority Interrupt, Message Priority
Interrupt, Radio Disable Priority Interrupt, and All Call
Priority Interrupt. When this feature is enabled by your
dealer, you can interrupt an ongoing call by initiating an
emergency call, all call, or sending the Radio Disable
command or a short message.
Pseudo Trunk
The Pseudo Trunk feature allows the radio in repeater
mode to select an idle time slot for communication. When
one slot is busy, the radio automatically selects the other
time slot for communication. In this way, the feature
improves channel utilization and decreases the
interference to other ongoing calls on the channel.
To enable the feature, go to Menu > Programming >
Channel > Slot > Pseudo Trunk.
XPT System
The XPT System is based on the digital conventional
system. It connects multiple repeaters to create an
extended pseudo trunking system. The system allows the
radio to communicate through any of the repeaters in the
site by sharing the logic channels of these repeaters, so as
to increase the channel utilization and extend the
communication capacity. In such case, a dedicated
control channel is no longer required.
XPT system is categorized as single-site trunking system
and multi-site trunking system.
l Single- site trunking system consists of a master
repeater and multiple slave repeaters. These
repeaters are connected by exchange devices.
l Multi-site trunking system consists of multiple single-
site trunking systems. They are connected by the
multi-site IP network.
The radio in the XPT system supports services including
call, data, roam, emergency, and priority interrupt. For
detailed information, see the features in conventional
mode.
