If a slave sub-rack is connected via TSU012 Control Unit or TFLB Interconnect Link 
Unit, alarms from slave/remote sub rack are also reported through the TPR back 
plane at the auxiliary DB9 female connector, providing alarm relay logic similar to 
the master ( see Tab. 7) 
 
NOTE: TPR subrack provides connections for more detailed alarms, at the right 
most slots (see TSU012 control unit product specification)
