Radio Dispatch Sub-system
•
•
•
•
The radio dispatch application was customized according to ERL’s operational
requirements.
The development of application is based on Application Program Interfaces provided
by the Motorola’s Dimetra system.
All required functionalities are performed from the customized GUI of the dispatch
terminals. Key functions include:
– Calling of trains by their assigned Train Run Number.
– Full duplex private calls between Dispatcher and Train Drivers.
– PA announcement to trains from Dispatcher at OCC.
– Etc.
Samples of the GUI display are as follows.
