PSUs need to be programmed with Normal Squelch (or NID = F7E) in order to hear
those calls.
IMPORTANT!
Encryption Key Translation is not supported by the DVRS.

Private Calls

Private Calls (Local to Local PSU; Local to System PSU; System to Local PSU) are
supported on 'DVRS Enabled' PSUs only. Generic P25 PSU mode does not support
Private Calls via DVRS.

PSU Talk Permit Tones

'Go Ahead' tones are generated in the 'DVRS Enabled' PSUs. Different tones are
generated to indicate if the DVRS is in Local or System Mode or the call is P25
Encrypted. As a programming option Local Mode tones can be generated when the
System is busy and only Local repeat is available. Alternatively, the PSU user can get
'System Busy' tones and be forced to wait for system grant (see 'Digital System Setup
Menu' in the DVRS Programming section). Generic P25 PSU mode does not support
Talk Permit Tones when operating through the DVRS.

Status Broadcast

If enabled in the DVR ("Network Status Reporting Interval", Digital System setup
screen), the DVR transmits status broadcasts that can be received only by P25 DVRS
Enabled PSUs:
FNE Out of Range
DVR Local only status
Site Trunking
Failsoft
IV&D Data Enabled / Disabled status
NOTE:
Only a Primary DVR can transmit Status Broadcasts.
The above status indication is not available to Generic P25 PSUs when using the DVRS.
The status indication is passed to the Local PSU every time the status changes. If there
is no change to the status, the DVRS sends status indication to the Local PSUs at a
preprogrammed time interval. The DVRS also sends a network status notification every
time a Local PSU is affiliated with the System via DVRS. If the FNE enters Failsoft
mode, the MSU proxies the Failsoft message (if Failsoft is enabled in the MSU). The
DVR stops sending Status Broadcast to the local DVRS Enabled PSUs and periodically
transmits Failsoft message instead.
