call
A complete exchange of information between two or more parties. A call
requires a receive signal path and a transmit signal path. In conventional
systems, a call is an over, but in trunked systems, a call may be a
conversation, made up of a number of overs.
Cartesian Loop The reciter’s RF output is fed to the PA through the transmit forward path.
A coupled signal from the PA’s RF output is fed back to the reciter through
the transmit reverse path. The reciter uses this feedback through a Cartesian
Loop to linearize the RF amplification system. Linearization is required to
accurately transmit complex waveforms which vary in frequency and
amplitude, such as those used in P25 Phase 2.
central voting Voting that is centralized at one member of the channel group.
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 group A single logical channel consisting of a set of base stations. The members
of a channel group are linked by an IP network and share a common
multicast IP address.
channel profile A named group of configuration settings that help to define the properties
of a channel. Each channel in the channel table must have a channel profile
assigned to it.
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).
community
repeater
Repeater that is shared by several user groups.
configuration file Consists of all the configuration settings needed for a base station, stored
as a file.
conventional
network
Systems that do not have centralized management of channel access.
System operation is entirely controlled by system end users.
