3.7.4 Protected System Configuration 

 

A protected DXL8000 configuration includes a pair of DXL8000 transceivers, ODUs and a DXL 
Hot Standby 

Protection 

switch, as shown in the figures below. 

The DXL Hot Standby Protection 

switch ensures uninterrupted service and protects against equipment failures for critical 
microwave communication links by buffering, monitoring and switching to a backup transceiver in 
the event of a major trigger relay alarm from the primary transceiver. Please refer to pages 

3-12 

to 

3-13 

and the 

DXL Hot Standby Protection Switch User and Technical Manual 

for more 

information.  

 

The system includes ODUs in a coupled or uncoupled configuration. The DXL8000 transceivers 
required for your operational microwave transmission may be located across a wide area and 
can be interlinked to transmit and receive video, audio and data streams. Examples of protected 
DXL8000 configurations are shown below:
