nterface − 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
