DVRS Installation & Programming Guide – PART II
Range
If this box is checked, the TG Proxying
feature is disabled and the Local PSU
and MSU must be on the same TG in
order to establish communications. If the
Local PSU and the MSU are on different
TGs, the Local PSU will not be able to
affiliate and as a result it will not be able
to make calls until the TG selection is
matched.
When enabled, the DVR gives higher
priority to a LPSU call initiated during an
ongoing LPSU call.
Enables / Disables the PSU Voice
takeover when the MSU is receiving and
DVR repeating an outbound call.
Enables / Disables the PSU Signaling
takeover when the MSU is receiving and
DVR repeating an outbound call.

(Failsoft, Out of Range or Site Trunking)
as well as 'Local Mode' Indication to the
Local PSUs.
Defines the digital audio buffer, which
prevents the loss of audio at the
beginning of transmission while the MSU
is acquiring channel grant. Applicable to
Trunking systems where system access
channel grant may take 1000 – 1500ms
This setting must be matched with the
APX

adequate PSU unmuting
Determines the time a PSU ID will be kept
in the DVRS affiliation table without
detecting any activity from the PSU. After
the

APX Series P25 Interface
Notes
Applicable to Digital &
Mixed Mode only.
Allows Local PSU users
to switch to different TGs
and their calls to be
proxied by the DVRS
regardless of the
selected MSU TG (as
long as it is 'DVR
Enabled').
The Local PSU will wait
two times the
programmed interval
before it declares being
Out Of Range.
Default setting is
1000ms. Reducing the
buffering time provides
lower throughput delay,
however may result in
truncated audio when
accessing the system
due to poor coverage
takes longer.
Default setting is 40ms
Recommended setting
should match that of the
'Affiliation Inactivity
Timeout' of the System
(default is 12 hrs).
