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.
