Automatic PSU Revert to Talk Around (TA)

The DVRS Enabled PSU (with firmware R09.00.00 or later) 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 outside 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.

PSU Group Services

Pre-requisites for PSU Group Services support via DVRS:
•
APX series 'DVRS Enabled' PSUs with Firmware R14.50.00 or later
•
P25 Trunked FNE with firmware 7.16 or later
•
DVRS with firmware R1.22 / MSU R14.50.00 or later
•
DVRS in SYSTEM or LOCAL Mode, Digital Channel Selected
•
MSU that DVR is interfaced to receiving Group Services while on P25 Trunked
FDMA Mode
The following Group Services can be supported by the DVRS:

Group Text

Group text is an unconfirmed message that is sent to all members of a Talkgroup. The
DVRS passes the Group Text messages to the local PSUs. If the Local 'DVRS Enabled'
PSU users want to receive only Group Text Messages sent to the PSU selected
Talkgroup, then the PSU must be programmed for 'Selective Squelch' instead of the
default 'Normal Squelch'. If programmed for 'Normal Squelch', the Local PSU will
receive all Group Text Messages proxied by the DVRS regardless of the Talkgroup
currently selected on the PSU.
NOTE:
The above also applies to voice calls in general – if the Local PSU users want their
PSUs to only unmute to the PSU selected Talkgroup, then they need to program
'Selective Squelch' in the PSU. If they are using the default 'Normal Squelch' setting, the
PSUs will unmute to all calls proxied by the DVRS regardless of the incoming call
Talkgroup.
