When used in
a mobile radio system, Automatic Number Identification (ANI) describes the process where a
radio user is identified automatically each time they activate the radio PTT.
Automatic
Number Identification (ANI) eliminates the need for the mobile operators to identify
themselves. The simple action of pressing the Push To Talk (PTT) button sends a numeric
message to the base, immediately providing positive identification of the calling party.
In the most basic form this can be a digital numeric display. The CES ARi-195
base display decoder is able to queue a number of transmissions and is also able to
display a status digit to allow the driver to advise the base operator of additional
information (e.g., fleet number, vehicle type, even activity status can be logged by
providing a variable numeric indicator) all automatically, in a fraction of the time of it
would take using normal voice commands. More advanced systems can use computer software
such as the ARi-2000 to provide a computer assisted environment. This approach
opens up a host of possibilities such as displaying the actual name of the caller or the
type of vehicle the call is coming from, data logging and task related messages can be
processed. ANI and its enhancements can result in a number of operational
advantages. Less misuse of the radio system, easy identification of caller or plant,
simpler access to the base operator by the driver, (simply press the PTT and waiting for
the operator to respond). Advanced functions to meet operational requirements are quite
easily achieved. Enhanced efficiency means more productivity and less cost per message.
