The TPR subrack provides: 
•  power supply to the active plug-in cards (12VDC); 

•  alarm logic and relays; 

•  mechanical housing and positioning. 

 
 

 
 

 
 
 

 
 

 
 

The TPR sub-rack has a built-in alarm circuit: any fault in TFL or TFA causes a 

contact relay close or open. 
A sub-D 9 pins male connector at the back of the sub-rack gathers summary and 

specific alarms of master/local subrack (see Tab. 6)
