Digital DVR Mode - Operation and Programming Overview

Digital DVRS Mode assumes the following:
Selected DVR channel is programmed for Digital or Mixed Mode.
P25 PSU programmed for Digital DVR Operation and with Digital Mode currently
selected (referred to as a Local PSU).
A DVRS Enabled, P25 MSU Mode is selected on the O5 / O3 / M5.
The Digital Mode features supported by the DVR are listed in
The DVR Channel programming requires that
the specific DVR Channel and the Tx/Rx frequencies as well as the Tx/Rx NIDs of the
PSUs and the DVR are matched.
NOTE
Forced Analog Mode is a hybrid mode in which the communications between the DVRS
and the 'DVRS Enabled' P25 PSU are digital, while the voice communications are forced
to be analog. For more details, refer to
Mode – Operation and Programming Overview'

PSU Affiliation

When a Local PSU User selects a DVR Enabled TG, the Local PSU is affiliated via an
active Primary DVRS if:
The DVR is programmed for Digital (or Mixed) mode on the selected DVR
channel.
The same Digital DVR channel is selected on both the PSU and the DVRS.
Generic P25 PSU is registered during the first Group Call made after switching to
the DVR enabled Mode. 'DVRS Enabled' P25 PSU starts automatic affiliation
process upon selection of DVR Enabled Mode (no PTT required to start affiliation
process).
The maximum number of PSUs that can get affiliated with one DVRS is 256.

Group Calls

Inbound and Outbound Group Calls are supported by the DVRS as illustrated in
Appendix 4 and Appendix 5.

Talk Group Proxing

The Local PSU User can change the selected 'DVRS Enabled' TG and seamlessly talk
to the corresponding TG Users through the DVRS. The MSU can be on any 'DVRS
Enabled' TG, which may or may not match the TG selected by the Local PSU.
For example, if the Local PSU selects TG1 while the MSU is on TG2, the Local PSU can
talk to Local TG1 users as well as System TG1 Users via the DVRS i.e. the MSU will be
transmitting on TG1. If the MSU microphone is PTT-ed, both the MSU and the DVR will
transmit on the TG selected on the MSU i.e. TG2.
An outbound call received by the MSU on either TG1 or TG2 will be repeated by the
DVRS to the Local PSUs.
