In-Car Monitor

If In-Car Monitor is enabled in the DVR, the audio received from the Local PSUs will be
heard in the MSU speaker if the TG selected on the PSU is the same as the TG selected
on the MSU.
If the TG selected on the Local PSU is different from the one selected on the MSU (see
Talk Group Proxing), the voice received from the Local PSU will not be heard on the
MSU speaker unless the Hook Switch (HUB) feature is enabled in the DVR and the
Microphone is currently Off Hook.
Private Calls are never heard on the MSU speaker regardless of the Hook Switch (HUB)
status unless the Private Call involves the particular MSU.

Trunking System Status Indication

The following P25 Trunking system status indication is passed by the DVRS to the Local
'DVRS Enabled' PSUs when the DVRS is in the System Mode:

Failsoft

Out of Range

Site Trunking
The above status indication is not available to Generic P25 PSUs when using the DVRS.
The status indication is passed to the Local PSU every time the status changes. If there
is no change to the status, the DVRS send status indication to the Local PSUs at a
preprogrammed time interval. The DVRS also sends a network status notification every
time a Local PSU is affiliated with the System via DVRS.

Local Mode Indication

When the DVRS is operating in the Local Mode, the PSU User can see "LOCAL ONLY"
message displayed on the PSU screen.
The above indication is only available on 'DVRS Enabled' PSUs and is not available to
Generic P25 PSUs when using the DVRS.

Radio Check / Inhibit

Radio Check and Radio Inhibit functions are passed through the DVRS to the Local PSU
when the DVRS is in the SYSTEM or LOCAL mode. Those functions are available to
both 'DVRS Enhanced' and Generic P25 PSUs.

P25 Trunking OTAR

P25 Over The Air Rekeying (OTAR) is supported through the DVRS when the Local
PSUs are of the 'DVRS Enabled' type, the DVRS is in the SYSTEM mode and the MSU
is on a P25 Trunking mode. OTAR is not supported if generic P25 PSUs are used and /
or if the MSU is on a P25 Conventional channel.

Patch

When several TGs are patched on the System side (using the trunking group-regrouping
function), the DVRS ensures the patching is matched on the Local PSU side when
'DVRS Enabled' PSUs are used, the DVRS is in the SYSTEM or LOCAL mode and the
MSU is on a P25 Trunking TG.
