24 AMX Switch Series Installer/User Guide
Figure 2.12 illustrates a cascaded AMX switching system with a combination of blocking and non-
blocking configurations. In this example, the primary switch
supports eight users, and eight user
paths are connected to each secondary switch, creating a non-blocking configuration. The target
devices attached to the secondary tier will never be blocked and can be accessed at any time. The
secondary switches support eight users, but only four user paths are attached to each tertiary switch,
creating a blocking configuration. Thus only four target devices on each tertiary switch can be
connected to simultaneously, but these four connections can be shared among eight users. Once a
user closes a connection to a target device on a tertiary switch, that user path is open and can be
used to connect to any target device in the switching system.
