LBI-39169 GLOSSARY

TERM	DEFINITION
CNI	Conventional Network Interface − A conventional base station can be
	connected to the CEC/IMC switch via a CNI. The CNI is formed by a GETC
	shelf located at the conventional station that makes the station appear to a
	MIM as an EDACS site. In the CNI system, different Channel Guard tones are
	assigned to different talk groups.
Community Name	Used like a password in message, validating the right of the sender to access
	MIB data with a requested operation.
confirmed call	The confirmed call function ensures all EDACS radio systems being called
	have working channels available before the caller is given a channel access
	(talk permit) tone. This function can be disabled on a per system/group basis.
Console	Communication equipment which provides an operating position for a
	dispatcher.
Console Icon	The Console icon consists of equipment, displays, and controls where one
	operator interfaces with a radio system.
Convert To Callee	The convert to callee message is sent to a radio which attempts to initiate a call
	within a group which is already assigned a working channel. Upon recept of
	the message, the radio is prevented from transmitting and is placed in the
	receive mode on the assigned working channel.
control data	Control data includes any data used by the switch for system control.
CTIM	Centralized Telephone Interconnect Module − The CTIM is a CEC/IMC
	interface module used to connect Centralized Telephone Interconnect System
	(CTIS) equipment to the switch so radio users and dispatchers can access land-
	line telephone systems.
DATA	(see EDG interface module)
daemon	Background process that performs system-wide functions.
distributed multisite	Two or more IMC networks can be linked together for distributed multisite
	communication. Audio, mobile data/Aegis data and control data is transferred
	between the different IMC networks via a NIM at each IMC switch. (Also see
	StarGate Controller.)
DPRAM	Dual Port Random Access Memory − These specialized memory chips have
	two separate data buses that allow two microprocessor chips to quickly and
	efficiently transfer data between each other.
DVIM	Digital Voice Interface Module − The DVIM is a CEC/IMC interface module
	that connects Digital Voice Interface Units (DVIU) to the switch to provide
	Aegis digital and Aegis private voice operation for dispatch consoles and CTIS
	equipment.
DVIU	Digital Voice Interface Unit. Provides digital interface to the dispatch console
	and enables digital mode communications with the console operator.
