Specifies if the RSSI (signal
strength) and or Squelch (signal
quality) should be used to
determine the channel ON /
OFF status.
When the "Channel Type"
is "Digital", the only valid
option for this field is
"RSSI".
For the RSSI threshold
and hysteresis
configuration, see the
"RSSI Thresh" column of
the "Repeater Channel
Setup" window and the
"RSSI" group of the
"Hardware Setup" window
respectively.
For the Squelch
configuration, see the
"Squelch" group in the
"Hardware Setup" window.
Determines the sensitivity of the
VR. The VR ignores any signals
below this threshold.
The Duplexer Rx Insertion
Losses as entered in the
Interface to Mobile Setup
screen are considered to
calculate the RSSI at the
Antenna Port.
-105 to -65 (-100) dBm
DVR / DVR-LX 800 MHz
only: -95 to -65 (-80)
dBm
Threshold used during the
dynamic Busy Lockout Phase if
Primary / Secondary Enable
BL for Voice Comm is enabled
(see Digital Mode Settings).
Not applicable with
Booster PA.
Must match the P25 PSU Tx
NAC. Serves as CAS validation
in Digital Mode (equivalent to
Rx PL / DPL in Analog Mode).
F7E Enables the VR to
receive on any NAC.
Applies to Digital, Mixed
and F.Analog Mode.
Must match the P25 PSU Rx
NAC. Serves as CAS validation
in Digital Mode (equivalent to
Tx PL / DPL in Analog Mode).
Applies to Digital, Mixed
and F.Analog Mode.
When a Secondary VR detects
a request for VR repeat and it
does not detect any Heart
Beats coming from the current
Primary VR, the Secondary VR
checks for activity on its Tx
frequency (exceeding the Tx
RSSI Th) to determine if the
lack of Heart Beat is due to the
Primary VR already repeating
the Call. If no activity is found to
exceed the Tx RSSI Th the VR
will check again and if 3 heart
beats are missed, the VR will
negotiate becoming a Primary.
