Local Mode Indication; Radio Check / Inhibit; P25 Trunking Otar; Patch - Futurecom DVRS User Manual

Local Mode Indication

When the DVRS is operating in the LOCAL mode, the DVRS Enabled PSU User can
see "LOCAL ONLY" message displayed on the PSU screen if Status broadcast is
enabled in the DVR as described in the 'Status Broadcast' paragraph. The above
indication is only available on 'DVRS Enabled' P25 PSUs and is not available to Generic
P25 PSUs.

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 Enabled' and Generic P25 PSUs when the MSU is operating on a P25
Trunked or P25 Conventional Mode. If the MSU gets radio inhibited, the DVR switches
to 'VR Disabled' mode of operation.

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.
IMPORTANT!
System design must ensure that PSU TGs that are programmed for TG Translation
are outside of the range of Talkgroups used on the trunking system.
MSU Patch is supported as follows:
•
Inbound call from PSU on TG Translation enabled TG will be translated to the
patch supergroup and repeated locally and to the system.
•
Outbound call will be repeated as is (with the supergroup TG ID).
