Functional Description
The Communicator comprises two functionally independent units: PDA and
CMT.
CMT.
The PDA implements the communicator application platform.
The CMT implements the GSM transceiver and basic data functionality, both
transparent and non–transparent data. All UI functionality is combined into one
UI module (BS2) but both PDA and CMT control their respective UI indepen-
dently.
transparent and non–transparent data. All UI functionality is combined into one

The Functional units and the implementation differ slightly. Due to mechanical
reasons some components are placed into a different module than they func-
tionally belong. E.g. audio components are placed into BS1 (PDA) module
even if they functionally belong to the CMT.
