System originated call

System originated calls are a result of calls presented to access lines.

System

The system searches for the portable.

Portable

The portable is idle most of the time, but about once every second it monitors
the signaling channel to see if there is a call. If there is a call, it establishes a
radio link.
After the system establishes a link, the link is moved to the best radio for the
link if the Base Station cell centers are not too close together (that is, the
-45 dBm cell contours do not overlap).

Base Stations must be close together at the cell center.
Cell centers should not be too close to each other.
The -45 dBm contours of different cells should not overlap each other;
however, a slight overlap is not serious.
