210 Glossary
Digital outputs are inactive if the base station is doing nothing to
them. They are floating, open collector outputs. Digital inputs
are inactive when they are open circuit.
Intercom mode makes it possible for the operator at the dispatch
center and the servicing technician at the base station to
communicate with each other over the line. It connects the base
station microphone to line out.
An isolator is a passive two-port device which transmits power in
one direction, and absorbs power in the other direction. It is used
in a PA to prevent damage to the RF circuitry from high reverse
power.
Kerchunking is transmitting for a second or less without saying
anything in order to test the base station. This results in a
'kerchunk' sound.
A TB8100 is a line-controlled base station when it receives audio
(sending it out via its systems interface), transmits audio received
over its systems interface, and its transmitter is keyed via the Tx
Key line.
Once you are connected to a BSS, you log on to a base station.
This establishes communications between the Service Kit and a
particular base station.
The navigation pane is the left-hand pane of the Service Kit
application window. It displays a hierarchical list of items. When
you click an item, the main pane displays the corresponding
form.
