EDACS

Enhanced Digital Access Communication System – The term "EDACS radio system" refers to RF equipment that may be interfaced to the EDACS CEC/IMC Digital Audio Switch. The RF equipment may be located at a single location, such as an EDACS trunked site or it may be located at several locations, such as in a voting system. Other examples of EDACS radio systems include simulcast, CNI, and SCAT systems.

EDG interface module

EDACS Data Gateway interface module – Mobile data is forwarded to the CEC/IMC Digital Audio Switch from the EDG computer equipment via the EDG interface module. This interface module's Controller Board is typically labeled "DATA."

extended network

Extended network is a System Manager term which refers to distributed multisite communication. Users must be "extended network enabled" before distributed multisite communication can occur.

Failsoft

Failsoft refers to an EDACS trunked site's mode of operation when the site's Site Controller is not operational. The site's control channel GETC has primary control of basic trunking features.

Failsoft 2

Failsoft 2 refers to a site's mode of operation when its control data link is not operational. This could occur, for example, if the phone lines between the uplink and downlink GETCs are defective. During the Failsoft 2 mode, multisite communication with units logged onto the failed site is not possible.

field

Field refers to the area of the dialog box which allows data entry for a particular parameter or displays information concerning operation of the CEC/IMC relevant to that particular dialog box.

FIFO

First In First Out – FIFO integrated circuits provide the interface between digital information paths of widely varying speeds. This allows the information source to operate at its own intrinsic speed, while the results may be processed or distributed at a speed commensurate with need.
