Switch, system integration
3.2.10
In this typical configuration, the RF signal is connected to Port B of the
ViaLiteHD
RF splitter and the two outputs, ports A and C are fed into
two
ViaLiteHD
single transmitter modules. These modules are connected via two separate optical fibres to two
ViaLiteHD
single receiver
modules. These form the PRIMARY and SECONDARY paths. The RF outputs of the PRIMARY and SECONDARY Receivers are
connected to ports A and C respectively of the
ViaLiteHD
3 port switch module. Port B of the
ViaLiteHD
3 port switch module is fed to the
user equipment. Control lines in the chassis backplane connect alarms to adjacent slots. These are used to control the status of the switch
module and ensuring that the RF Switch selects the SECONDARY path in the event of a failure in the PRIMARY path.

The chassis configuration below can be used to provide four redundant transmitters in a single
ViaLiteHD
3U chassis. For simplicity the
chassis configuration is viewed from the rear.
