LBI-39169 GLOSSARY

TERM	DEFINITION
SNMP	See Simple Network Management Protocol.
StarGate	In EDACS trunking, links up to eight EDACS wide-area multisite networks to
	create a single, seamless network.
StarGate Controller	A StarGate Controller is an IMC switch specifically configured for
	distributed multisite operation. It is the central point or "hub" for all distributed
	multisite communications.
SubSite Number	This is the EDACS SubSite Number which uniquely identifies the SubSite
	device on a particular Node. A channel is a subsite device.
super user	The root user who has special privileges. Same as the System Administrator.
Switching Center	Collection of node level devices physically connected to the IMC.			These
	devices include the PI, BCU, CAL, EDG, and Consoles.
System Manager	The System Manager is a DEC multitasking computer which performs
	features such as monitoring system operation, generating management reports,
	individual unit enable/disable and dynamic regrouping.
T1/E1	Digital landline and microwave transmission standards used in the United
	States and Europe.
TCP	Transmission Control Protocol.		A connection-oriented protocol	with
	acknowledgments and retries.
TDM	Time Domain Multiplexing.	Technique used to multiplex multiple signals
	onto a single hardware transmission channel (bus) by allowing each signal to
	use the channel for a short time before going on to the next one.
TDM bus	Time Division Multiplexed bus − The TDM bus in the CEC/IMC switch is a
	digitally multiplexed bus system used to transfer audio/mobile data/Aegis data
	throughout the CEC/IMC switch. Each signal coming into the CEC/IMC
	switch is assigned a TDM time slot and receiving devices extract the digitized
	signals from the appropriate time slot.
Technician (or Tech or	Customer personnel whose main responsibility is to install, maintain, and
EDACS technician)	troubleshoot individual EDACS platforms, such as GETCs, Site Controllers,
	EDGs, and IMCs. Technicians require software interfaces that run on common
	laptop/desktop personal computers to assist in hands-on setup of a particular
	platform.
Telnet	The TCP/IP protocol that enables a terminal attached to one host to log into
	other hosts and interact with their applications. It is the Standard internet
	protocol for terminal emulation.
TFTP	Trivial File Transfer Protocol.	A basic TCP/IP protocol used to upload or
	download files. Typically uses include initializing diskless workstations.
tracking	In a multisite network, all active radios log into their particular system. This
