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.

In the remainder of this chapter, 'basic system'
refers to the system in figure 32. 1 .

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).

Note
In the remainder of this chapter, 'basic
redundant system' refers to the system in
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.
