SCAT OPERATION
A Single Channel Autonomous Trunking (SCAT) System
operates with the same set of features as a standard EDACS
system. The only significant user change relates to the BUSY
icon. Since only one channel (operating as both control and
working channel) exists in a SCAT system, the BUSY icon
will be displayed when the SCAT channel is in the working
channel mode. When the transmission on the channel is
completed, the BUSY icon will disappear to indicate the
return of SCAT control channel signaling.
