configuration file
A configuration file consists of all the configuration settings needed for a
base station, stored as a file in the configurations folder. Configuration files
have the extension *.t8c.
connection A connection is a named group of settings that the Service Kit uses when
establishing communications with a base station.
control bus The control bus is used for communications between modules in a base
station. It is an I
2
C bus, a bi-directional two-wire serial bus which is used
to connect integrated circuits (ICs). I
2
C is a multi-master bus, which means
that multiple chips can be connected to the same bus, and each one can act
as a master by initiating a data transfer.
control panel The control panel is an area at the front of the base station with buttons,
LEDs and other controls that let you interact with the base station.
CTCSS CTCSS (continuous tone controlled squelch system), also known as PL
(private line), is a type of signalling that uses subaudible tones to segregate
groups of users.
custom action A custom action is a user-defined Task Manager action that consists of more
than one pre-defined action.
custom input A custom input is a user-defined Task Manager input that consists of a
combination of pre-defined inputs.
CWID CWID (Continuous Wave IDentification) is a method of automatically
identifying the base station using a Morse code. Continuous wave means
transmission of a signal with a single frequency that is either on or off, as
opposed to a modulated carrier.
D
DAC Digital-to-Analog Converter. A device for converting a digital signal to an
analog signal that represents the same information.
DCS DCS (digital coded squelch), also known as DPL (digital private line), is a
type of subaudible signalling used for segregating groups of users. DCS
codes are identified by a three-digit octal number, which forms part of the
continuously repeating code word. When assigning DCS signalling for a
channel, you specify the three-digit code.
DDC Digital Down Converter. A device which converts the digitised IF signal of
the receiver down to a lower frequency (complex baseband) to suit the DSP.
de-emphasis De-emphasis is a process in the receiver that restores pre-emphasised audio
to its original relative proportions.
