Architecture
32.1 Introduction
The exact layout of the Praesideo system depends on 
the number and type of units that make up the system 
This chapter contains some easy-to-follow examples of 
(strongly simplified) Praesideo systems to illustrate the 
possibilities.
32.2 Basic 
system
See figure 32.1 for an example of a basic system.
32.3 Redundant cabling
The basic system has no redundant cabling. If the cable 
between the call station basic and the power amplifier 
breaks, it becomes impossible to broadcast calls or 
background music. This can be solved by creating a 
redundant cabled system (see figure 32.2).
The only difference between the basic system and this 
redundant cabled basic system is the connection 
between the power amplifier and the network 
controller. The equipment now forms a ring. If a cable 
breaks, the system remains functional.
