TB8100 Service Kit User’s Manual Working with Channel Profiles 111
Receiver Gating
In the Add or Edit Channel Profile dialog, the Receiver Gating tab configures
the unmuting of the receiver (also known as receiver squelch). You can enable
and configure RSSI and/or SINAD gating. These, together with subaudible
signaling, are inputs into the mute/unmute decision. These inputs can be
combined in different ways using Boolean logic (AND or OR). Red lines and
drop-down list boxes show how they are currently combined.
RSSI
gating operates more quickly and is suitable for multiple repeater links or
for base stations with external data modems. SINAD
gating takes longer but is
more immune to noise interference and is suitable for the repeater itself or for
a line-connected base station. For information about gating in a base station
with Power Save, see the Installation and Operation Manual.
