EDACS Trunking Mode (ED) – You can set your scanner so it
decodes talkgroup IDs used with EDACS (GE/Ericsson/M/ACOM)
trunking systems. This setting is called the EDACS mode.
EDACS systems are used primarily by business or private
communications service providers, as well as by some public
safety organizations.
