Notes
VR Ch Mixed Mode
Hold Timer
0 to 255 (10) sec
This timer determines the VR Mode
Hang Time. If VR receives a call from
an Analog PSU, the VR will stay in
Analog mode until this timer expires.
Any System reply received before the
timer’s expiration will be transmitted in
Analog Mode. The timer is started when
the originating Analog PSU dekeys.
Upon expiration of the timer, the VR
switches to digital repeat mode.
Applicable to Mixed
Mode VR Channels
only. When a Mixed
Mode VR channel is
selected, the default
VR mode is P25
Digital.

Enforce TG
Matching
Check box
(unchecked)
When this box is unchecked (default), it
allows Local PSU users to switch to
different TGs and their calls to be
proxied by the VR regardless of the
selected MSU TG (if it is ‘DVRS
Enabled’).
When this box is checked, the Local
PSU and MSU must be on the same TG
to establish communications. If the
Local PSU and the MSU are on
different TGs, the Local PSU will not be
able to affiliate and as a result it will not
be able to make calls until the TG
selection is matched.
Applicable to Digital
& Mixed Mode only.
PSU Priority
Inbound Takeover
Allowed
Check box
(unchecked)
When enabled (checked), the VR gives
higher priority to a LPSU call initiated
during an ongoing LPSU call.
Outbound
Takeover by
Signaling Allowed
Check box
(unchecked)
Enables / Disables the PSU Signaling
takeover when the MSU is receiving and
VR repeating an outbound call.
Outbound
Takeover by Voice
Allowed
Check box
(unchecked)
Enables / Disables the PSU Voice
takeover when the MSU is receiving and
VR repeating an outbound call.
Network Status
Reporting Interval
0 to 255 (45) sec
Determines the intervals for sending
Trunking Network Status messages
(Failsoft, Out of Range or Site Trunking)
as well as ‘Local Mode’ Indication to the
Local PSUs.
The Local PSU will
wait two times the
programmed interval
before it declares
being Out of Range.
PSU Digital Audio
Queuing
700 to 1800
(1250) ms
Defines the digital audio buffer, which
prevents the loss of audio at the
beginning of transmission while the MSU
is acquiring channel grant. Applicable to
Trunking systems where system access
channel grant may take 1000 – 1500ms
Reducing the
buffering time
provides lower
throughput delay,
however, may result
in truncated audio
when accessing the
system due to poor
coverage takes
longer.
