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.
