Term Definition
CARD
Suite
Software GAI-Tronics’ radio configuration software application for a personal computer. It is used
to program and change the operating characteristics (features and options) of the ICP9000
Navigator and some other GAI-Tronics products.
Channel A single path, separated by frequency or time divisions, for transmitting electrical signals.
A receive (one-way) or receive and transmit (two-way) frequency path.
Channel
Alias
Name The Alias Name is the assigned user name for a particular channel. Each channel can have
up to four alias names, one for each transmit frequency or current. Alias Names can be up
to 12 characters in length and are programmed through CARD Suite software.
CSQ Carrier squelch
CTCSS A means of grouping users of a common radio channel. Subaudible tones are transmitted
with audio; a particular radio’s speaker (or the speakers of a group of radios) unmutes to
broadcast a transmission only if the associated subaudible tone identifies it as belonging to
the radio’s user group.
CDCSS A system analogous to CTCSS but using low-speed digital signaling instead of subaudible
tones.
DPL Digital Private Line
A continuous sub-audible data signal that is transmitted along a carrier. A radio that has
DPL on the receive frequency requires both the presence of carrier and the correct DPL
code before it unmutes. If there is DPL on the transmit frequency, all transmissions on that
channel are modulated with the DPL code.
HLGT High Level Guard Tone notifies the selected base station of a change in its operating mode.
LED Light emitting diode
LLGT Low level guard tone
LOBL When flashing, the Line Operated Busy Light indicates that a parallel console or desk set is
transmitting on the associated channel. Transmission on that channel will not be possible.
PL Private Line (CTCSS/CDCSS squelch) - A continuous sub-audible tone that is transmitted
along with the carrier. A radio that has PL on the receive frequency requires both the
presence of carrier and the correct PL tone before it unmutes. Also, it there is PL on the
transmit frequency, all transmissions on that channel are modulated with the PL tone.
PTT Push-to-talk
Supv Supervisory Control - The Supervisory Control ( SUPERVISOR ) button gives a console
operator the ability to supervise any or all of the channels in a multi-console system.
Select
Speaker The select speaker provides the audio for the selected channel.
Unselect
Speaker The unselect speaker sums the audio from all unselected channels.
