rest of the system subscriber units without any danger of unintentionally switching a
DVRS mode.
In both cases, Dispatcher sends a Call Alert (Page) to a specific MSU ID, which in turn
causes DVR mode change in the following order: OFF-SYS-LOC-OFF with each
received Page.
The DVRS sends status updates to the Fixed Network Equipment System for each
mode change (P25 Trunking systems only!).
The status updates are sent in the following format:
Status 1 = OFF mode
Status 2 = LOCAL mode
Status 3 = SYSTEM mode
Dispatcher cannot force a Non-Primary DVR to become a Primary and cannot activate a
DVR when a 'VR Disabled' mode is selected on the control head.
The MSU needs to have the same unit ID programmed for all DVRS enabled
systems/modes in order to have reliable remote mode change operation via Call
alert page to MSU.
