AUTOMATIC MULTIPLE SITE SELECTION
(AMSS)
The automatic multiple site selection (AMSS) feature
extends communications beyond the reach of a single
trunked site. In a system where wide-area coverage is
required, multiple trunking sites are used.
AMSS automatically switches the radio to a different
site when the current-site signal becomes too weak.
Typically, this happens when the radio is moved out of
the range of one site and into the range of another.
Under normal conditions, this switching is invisible to
the user.
