PSU Call Alert

PSU call alert is supported via the DVRS when the MSU is operating on a P25 trunked or
P25 conventional mode and when the PSU is either P25 DVRS Enabled or P25 Generic.

PSU Message

The message feature is supported on all types of P25 PSUs when the MSU is operating
on a P25 conventional mode only.

PSU Status Update and Status Request

The PSU Status Update & Status Request features are supported on all types of P25
PSUs when the MSU is operating on a P25 conventional or P25 trunked mode.
PSU IV&D
The DVRS supports IV&D for only one PSU at any time. The use of PSU IV&D requires
P25 'DVRS Enabled' PSUs, a DVR in LOCAL or SYSTEM mode operating on a P25 digital
or Forced Analog/Forced Analog All channel, and MSU operating on a P25 Trunked mode.
Voice operation and signaling (such as call alert etc.) initiated from the MSU or PSU take
priority over data operation. The DVRS Enabled PSU supports clear data only.

PSU Location Reporting

Location Reporting is supported on 'DVRS Enabled" PSUs when the MSU is operating on
a P25 Trunking System. This feature relies on PSU IV&D functionality described above.
Personnel Accountability
Personnel Accountability feature allows the user to respond to the group or individual
evacuation command from the incident commander through FNE. When the subscriber
receives the EVAC command it plays alert and display corresponding to command type in
packet. The user presses PTT to stop playing alert and display then send back EVAC ACK
to FNE through DVRS
.
Notes: The evacuation command includes group and individual target and can be
transmitted on control channel or working channel.

Automatic PSU Revert to Talk Around (TA)

The DVRS Enabled PSU can be programmed to automatically revert to TA if it goes
outside of the DVR radio coverage range. The PSU automatically reverts to normal full
duplex operation as soon as it re-enters the DVR radio coverage range. If using a simplex
DVRS channel, the simplex PSU can be programmed to automatically revert to TA so that
it can transmit even when the PSU is out of the range of the DVRS. This way, simplex
PSU-to-PSU calls will be allowed regardless of the presence or absence of the DVRS.
