3 Expansion Stages and System Capacity
The basic systems can be expanded using interface cards, system modules, an 
applications card and licences. The expansion possibilities available and the 
maximum system capacities need to be known so the communications system 
can be ideally adapted to customer requirements. With the project data the 
optimum hardware configuration is easily determined using the project plan-
ning application Aastra Plan.
