Programming of Generic P25 PSU for Digital DVRS Mode

The programming of a Generic P25 PSU requires matched DVR – PSU programming of:

DVR Tx and Rx Frequencies

Tx and Rx NIDs (NACs)

TG IDs
IMPORTANT: The digital PSU can not talk through the DVRS (in digital mode) unless
the selected conventional ASTRO PSU mode is programmed with a valid system TG ID.
The PSU must affiliate through the DVRS! Therefore the PSU must be programmed with
a valid ID and the selected mode on the PSU must be programmed with a valid TG ID.
Typically the conventional ASTRO ID of the PSU must be set to match that of the
trunking system PSU ID.
If the PSU needs to support say 10 TGs via DVRS, then the PSU must be programmed
with 10 Conventional ASTRO personalities and each personality should be linked
(strapped) to the corresponding TG ID.
Programming of the P25 PSU (Generic P25 or DVRS enabled) for operation
on Conventional P25 MSU System
Both PSU types must have the Tx and Rx NACs matched with those programmed in the
DVR.
The 'DVRS Enabled' PSU needs to be programmed as described in the
the 'DVRS Enabled' PSU'
dedicated TG IDs then all system radios transmit with the default TG ID = 1. When the
PSU is programmed as DVRS Enabled, the default TG ID = 2 and it must be changed to
TG ID=1 in order to match the rest of the system radios. If the Conventional P25 System
is using dedicated TG IDs, then the DVRS Enabled PSU must be programmed with
corresponding conventional personalities using the required TG IDs.
In the Generic PSU, the default TG ID = 1 so it matches the rest of the system radios. If
the Conventional P25 system is using dedicated TG IDs then the Generic PSU must be
programmed with corresponding conventional personalities using the required TG IDs.
Programming of the P25 PSU (Generic P25 or DVRS enabled) for Inbound
Digital Takeover
If "Inbound Digital Takeover" is not enabled in the DVR, the 'DVRS Enabled' PSU will
have 'Tx inhibited on carrier' (equivalent to Smart PTT enabled). If "Inbound Digital
Takeover" is enabled in the DVR then the DVRS Enabled PSU should have Smart PTT
Disabled so it can interrupt outbound calls provided it is using a different TG ID
(proxying) from the TG currently selected on the receiving MSU.
A Generic PSU must have Smart PTT disabled if "Inbound Digital Takeover" is enabled
in the DVR.
