Table 24 Programming Example - Remote Steering

NOTE:
F7E Enables the DVR / PSU to receive on any NID and TG ID.
The F7E setting ensures the DVR will receive when the PSU transmits different TX NIDs
(4, 5, 6 in the above example). When a PSU user selects TG2 and sends a Call Alert /
Page to the DVR (using the unique DVR ID number), the PSU will transmit with TX NID 5.
The DVR will detect steer NID 5 and switch the MSU to TG2. The DVR will be repeating
the call with TX NID 10, which is received by the PSU on any of the steerable TGs. All of
the above settings refer to DVR CH1 i.e. the PSU remotely steers TGs on the same DVR
channel. DVR channel steering is not recommended.

Emergency in Digital Mode

The 'DVRS Enabled' P25 PSU can be programmed to block the launch of the Emergency
feature if the P25 Trunking system is in Failsoft mode (when 'Emergency Blocked in
Failsoft' is enabled).
The 'DVRS Enabled' P25 PSU can be programmed to use the programmed 'Fallback
Revert Talkgroup' while in Emergency and when on the dynamic talkgroup channel
without an assigned dynamic working group.

Emergency Alarm

When an affiliated Local PSU issues an Emergency Alarm, the active Primary DVR will
process the Emergency to the system as follows:
•
'Portable ID Display'
If the
the local PSU unit ID will be displayed on the MSU control head of the current
Primary DVRS.
•
The PSU unit ID will also appear on the display of the other local PSUs if they are
programmed accordingly.
•
During Emergency processing, the unit ID of the local PSU, which has initiated the
Emergency Alarm, may be displayed on the system PSUs / MSUs if those are
programmed accordingly.
•
The local PSU ID during Emergency may also be displayed on the dispatcher
console.
•
The DVR sends back an Emergency ACK to prevent the PSU from re-sending the
Emergency either right after the DVR decodes the Emergency request (if the
