channel 1. A path through which signals can flow.
2. In the RF domain, a frequency pair (or just a single frequency in a
simplex system).
3. A set of configuration information that defines the frequency pair and
other related settings (a channel configuration). “Channel” has this
meaning in the web interface.
channel spacing The bandwidth that a channel nominally occupies. If a base station has a
channel spacing of 12.5 kHz, there must be a separation of at least 12.5 kHz
between its operating frequencies and those of any other equipment.
channel table The base station’s database of channel configurations.
CODEC A device which combines analog-to-digital conversion (coding) and
digital-to-analog conversion (decoding).
colour code A marker determining which transmitted signals are gated. Inbound
messages must carry this code to be listened to. The colour code is
configured at the Node Controller. It can prevent interference from other
networks and define private talkgroups.
configuration file Consists of all the configuration settings needed for a base station, stored
as a file.
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.
DAC Digital-to-Analog Converter. A device for converting a digital signal to an
analog signal that represents the same information.
DDC Digital Down Converter. A device which converts the digitized IF signal of
the receiver down to a lower frequency (complex baseband) to suit the DSP.
dispatcher A person who gives official instructions by radio to one or more mobile
stations.
DMR Digital Mobile Radio. A set of standards and requirements endorsed by
ETSI and intended for professional mobile radio (PMR) users.
dotted quad A method for writing IPv4 addresses. The form is DDD.DDD.DDD.DDD
where DDD is an 8-bit decimal number.
downlink The transmission path from fixed equipment to mobile stations.
