Motorola MT2000 manual Smartnet

MTSX RSS		GLOSSARY
Software	A list of instructions that tell the computer what to do.
Squelch	A radio circuit that eliminates noise from the speaker when a transmitted signal is not
	present.
Sub-directories	A group of related files that are located on a hard disk or diskette. Sub-directories are used
	to organize your disks.
SMARTNET	A type of trunking system primarily used in support of Public Safety and Industrial
	communication systems. This type of system has emergency and dynamic regrouping
	capabilities.
System Central	Referred to as Central Controller, is the heart of Motorola's trunking system. The Central
Controller	Controller is a software controlled, computer driven device that receives and generates data
	for the trunked radios assigned to it. The Central Controller is responsible for monitoring and
	directing the operations of the trunked repeaters.
System ID	A number assigned to a trunked system distinguishing it from other systems. The system ID
	is sent out every 3 seconds on the Control Channel.
Talkaround	A frequency used for simplex conversations or radio-to-radio communications without the
Frequency	use of a repeater.
Talkback	Indicates that a call can be answered by pressing PTT and responding.
TalkGroup	A group of users in a Type II or Type IIi system.
Talk Permit Tone	A programmable brief series of beeps that provides the radio operator with an indication that
	a voice channel is available and assigned to them.
Talk Prohibit	An audible tone (honk) heard from the radio's speaker when the PTT is depressed. The tone
Tone	will be heard when either the radio is out of range of the system, or the radio is programmed
	with the incorrect system information.
Timeout timer	Time out timer limits the transmission period to a pre-defined time. The radio will
	automatically stop transmitting when the time period expires and the radio will generate an
	alert tone to notify the user that no transmission is taking place.TPL Tone	Private Line
	coded squelch. A channel that has TPL on the receive frequency will require both the
	presence of carrier as well as the correct TPL code before it will unmute. Also, if you have
	TPL on the transmit frequency, all transmissions on that channel will be modulated at a sub-
	audible level with the TPL code. Modulation is continuous.
TOT	Time Out Timer
Transmission	Upon releasing the PTT the radio will return to monitor the Control Channel	If the user
Trunking	desires to initiate another call.
Trunk	A communications path
Trunking	The automatic sharing of communications paths between a large number of users.
Type I	A type of trunking that is composed of Fleets and Subfleets, and limited by the size of codes
	of those groups. A type I system handshaking includes sending of the Acknowledge tone
	and High Speed Handshake.
