Ericsson LBI-39169 manual Tsi, Udp, Ups, Vmim, Xltr

GLOSSARY	LBI-39169
TERM	DEFINITION

login information is databased to allow the CEC/IMC to track individual radio units as they move from system-to-system. The CEC/IMC can then route wide area calls based on this database.

Transmission Control Protocol	The Transmission Control Protocol (TCP) is the TCP/IP protocol that provides
	reliable, connection-oriented data transmission between a pair of applications.
Trap	A message that reports a problem or significant event.
Trunking	The process of dynamically allocating a limited number of radio channels to
	groups of people for communication purposes.
TSI	EDG Trunked System Interface. The TSI handles all communications to the
	rest of the EDACS trunked radio system via the CEC/IMC CIM.
TU	Test Unit. The TU continually tests channels and provides an alarm to the Site
	Controller if a fault is detected. The TU and ACU form the Test and Alarm
	Unit (TAU).
UDP	User Datagram Protocol. Connection-less-mode transport protocol used by
	SNMP. Does not use acknowledgments or retries.
UPS	Uninterruptible Power Source. Used to keep the system running in the event of
	a power outage.
VMIM	ConVentional Interface Module − The VMIM couples the CIA secondary
	interface rack to the primary CEC/IMC switch interface modules. The VMIM -
	CIA set allows conventional base stations and conventional satellite receiver
	voting systems to be connected to the CEC/IMC switch.
X-model	A network-based display device that uses the X protocol over LAN to
	communicate with the host.
X-terminal	The high-end performing X-model targeted at technical environments.
XLTR	C3 Modular/Desktop Console Translator − Using data protocol conversion
	techniques, this interface module allows the CEC/IMC switch to communicate
	with a C3 Modular/Desktop console. The XLTR is placed in the control data
	path between the C3 console and its respective CIM.
