The Digital Vehicular
Repeater System (DVRS) feature
allows for an on-demand transportable repeater system,
which allows Portable Subscriber Units (PSUs) operating within range to
communicate through this repeater either locally, or even with previously
out-of-range Fixed Network Equipment (FNE) systems. A Digital
Vehicular Repeater System includes a third-party Digital Vehicular
Repeater (DVR) connected to a Motorola Mobile Subscriber Unit (MSU) transceiver that facilitates the system.
These two hardware units are typically mounted remotely in a vehicle’s
trunk space.
PSUs may be portable or mobile
radios that communicate with the DVR over a Conventional
link, which in turn communicates with the Trunking
FNE.
The DVRS is capable of three modes of operation: "System", "Local", and "Off".
When the DVRS is in the FNE (Fixed Network Equipment) "System" mode, there is full connectivity from PSUs communicating with the DVR (within the DVRS coverage area) to the dispatchers / FNE system.
When the DVRS is in the "Local"
mode, the DVR facilitates communications between PSUs within its coverage
area only.
Communications between the PSUs and the MSU (attached to the DVR)
are also possible; however, none of these radios can communicate with
the FNE system.
This mode is meant for local communications where system-wide communication
is not possible or necessary, such as Personnel Accountability
communications. (See also
the MSU System PTT in Local Mode
field and Outbound System
Repeat in Local Mode field.)
When the DVRS is in the "Off" mode, the DVR is completely disabled.
