P25 Digital Mode

This Chapter provides details on the DVRS Digital P25 Mode of operation.
The P25 Digital Mode assumes the following:

TM
XTL 5000 MSU with O3 or O5 Programmed for DVRS Operation

TM
XTL 2500 MSU with M5 Programmed for DVRS Operation

P25 Mode is selected on the MSU.

P25 PSU programmed for DVRS operation (Local PSU).

DVRS Enabled mode selected on the Local PSU.

DVR Channel is programmed in the DVR for Digital (or Mixed) Mode of Operation.
NOTE:
The basic principles of DVRS operation (both Analog and Digital) are as described in the
DVRS Operation Basics
Digital Mode of operation.
NOTE:
The Local PSU Notation throughout this Chapter refers to a P25 PSU which is
programmed for DVRS operation.
'DVRS Enabled' type Local PSU refers to the models described in Table 6 when
programmed for DVRS operation.
Some of the Digital Mode DVRS Features described are only available in P25 'DVRS
Enabled' type PSUs and not available in Generic P25 PSUs.
A System PSU refers to a P25 PSU which has a P25 Mode (Trunking or Conventional)
selected and 'talks' to the P25 Trunking or Conventional System Infrastructure directly
i.e. without a DVRS.
In in-band DVRS applications, the Local and System PSUs may be of the same model
and personality. When a DVR Enabled P25 Mode is selected, the PSU is referred to as
Local PSU. When a P25 System TG / Channel is selected, the PSU is referred to as
System PSU.
In Cross-Band DVRS applications, the Local PSUs operate in different frequency band
from the System infrastructure.
