Fireground (Fg) Signaling; Psu Iv&D; Psu Location Reporting; Psu Call Alert - Futurecom DVRS User Manual

•
If the revert TG is on the DVRS TG Translation list, then the Emergency will be
translated to the ID of the TG that is selected on the MSU.
•
Emergency Alarm will be repeated locally on all Translation enabled TG IDs that
are selected on local (affiliated with the DVRS) PSUs.
•
If the revert TG is not in the DVRS TG Translation list then the emergency will be
proxied and the inbound, outbound and local repeat will be on the new
emergency revert TG.
•
If the MSU (interfaced to the Primary DVR) is placed in Emergency and
programmed to revert in Emergency then a subsequent local PSU emergency
will also be translated and declared on the MSU's emergency revert TG.

Fireground (FG) Signaling

The Fireground deployment consists of a fleet of subscribers communicating with an
incident commander position using digital signaling and either analog or digital voice.If
Fireground (FG) signaling is enabled in the local PSUs and on the selected full duplex
DVRS channel, the DVR repeats locally the FG messages received form the local PSUs
to the FG terminal. FG Emergency signaling received from the local PSU can be either
repeated locally, sent to the system or both (as programmed in the DVR).
NOTE:
Only 'Generic P25' PSUs support Fireground operation.
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 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.

PSU Location Reporting

Location Reporting is supported on 'DVRS Enabled" PSUs when the MSU is operating
on a P25 Trunked system. This feature relies on PSU IV&D functionality described
above.

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.
