Introduction
The controller software of the network element is stored on the controller unit of the
network element. To upgrade this software the new software must be downloaded on
the network element. This can be done from the management system.
System controller software
The System Controller contains the software to control and support the network
element. The Manufacturers Executable Code (MEC) file contains the complete
software package for one network element. The software in the system controller is
also used to provide a basic configuration to the units connected to the system
controller. These other units obtain the appropriate part of the software package from
the System Controller during the system start-up or when a unit is inserted.
Two memory stores
On the System Controller of the 1643 AM are two memory stores that can contain
each a different MEC. The store with the software that is executed is called the active
store and the other store is called the backup store. In case of a software upgrade, the
management system downloads a complete software package to the backup store of the
System Controller.
Switch stores
With a switch command from the management system, the software in the backup
store can be made active. The switch command switches between the two stores, thus
the active store becomes the backup store and vice versa.
