Glossary
A signal from a receiver that gives a positive indication
that a carrier or signal is being received and that the
receiver is unsquelched. It has the same function as
Carrier Operated Squelch (COS).
See COR.
A method of automatically assigning an IP address to an
Ethernet device at startup time. This method conserves
IP addresses in networks where devices do not stay
connected permanently.
A type of microprocessor, which is optimized for signal
processing functions.
Tones that are inserted into the audio stream when a
radio is squelched. Their absence indicates a receiver
unsquelched condition. Also called Pilot Tones.
A protocol designed to allow communications between
computers on different networks.
A group of computers and associated devices that share a
common communications line, typically within a small
geographic area.
A scheme where multiple units can share one IP address,
usually behind a router.
See Idle Tone.
A signal to a radio transmitter, which controls the actual
transmission of radio frequency energy over the air. Also
called a keyline.
A method of converting analog radio audio and flow
control signals into data and sending it to a distant unit to
be re-converted back into analog audio.
An additional layer to the Internet Protocol, which
ensures delivery of packets, sent across the network. It
can handle situations such as lost packets or packets
arriving out of order.
An additional layer to the Internet Protocol which does
not ensure delivery of packets, but which offers much
lower transmission overhead than TCP.
Also called Voice over Packet (VoP), a method of
sending voice communications across a digital network.
A network, which is spread out over a wider area, such
as around a city or state. It may include other public or
shared networks.
