There is a need for an automated method that will Motorola has several communication systems assure the distribution of the correct firmware load that are composed of two or more devices connect- across all devices within the network. It is also ed to a network. In some of these systems all desirable to cross load the correct firmware in the devices within the network are identical, have the most efficient manner possible to minimize the same hardware and firmware, and one device from amount of time that the system is out of service. the network is connected to a centralized controller by a serial link. An example of such system is the SOLUTION IntelliRepeater site connected to a Zone Controller within a Smart&me system. The devices' firmware The following flow chart is a solution to the can be changed by downloading the data to one firmware cross loading problem.
