Handover
Network Registration Event. The Version 2 Aries probe produces the Network Registration
event when connected to a Motorola TETRA radio. This event occurs when the radio is powered
up and represents the time taken for the radio to discover a suitable control channel on the
TETRA network and then to register on the TETRA network ready. The event time is taken from
messages sent through the radio PEI port. The Aries probe measures the time from +CTOM
message to the +CREG message reporting the value in milliseconds.
Failed Handover, produced if a ‘No Service’ or ‘additional ‘Handover’ event occurs within X secs
of the original events. X is set to a default of 20 secs but is configurable for each probe.

The colour of the icon may be set to indicate the value of a parameter such as RSSI or LAC.
In addition the map also shows the base site and probe locations:
Base Site location, colour indicates LAC, see section 2.3 for
configuring the colour. If multiple base sites are specified with the same latitude and longitude then the
icon is split into the different colours indicating each base site LAC, antenna beamwidth and direction. The
different antenna radius sizes are purely to help identification.
Probe current location, colour indicates probe ID, see section 2.2 for configuring the colour
