Then connect the UL and the DL RF cable (which come 
from a TBSI or a TLCN module, depending on how the 
system has been designed) to the TFLN UL and DL 
ports, respectively.  
Use a specific torque wrench to fix these RF cables to 
DL and UL ports.

 

 
 
 

 
 
Remove the caps from TFLN optical ports and connect the 
SC-APC fibre optic cables to the ports. 
UL and DL cables coming from the same remote unit have 
to be connected to UL and DL ports marked by the same 
number on the TFLN front panel.  

 
 
 
 

 

As you switch on the system, carefully refer to the TFLN Start-Up section.  
Remember that remote units should be switched on before than the Master Unit in order to follow a 
correct Start-Up procedure. 

 

 
TFLN behaviour at system start-up 

Before the Master Unit is switched on, make sure that: 

•  all expected modules have been inserted into the Master Unit 
•  the modules have been connected each other by RF jumpers, according to what planned in the 

system design 

•  every TFLN local unit has been connected to relevant remote units 
•  each remote unit has been connected to its coverage antennas 
•  the supervision agent, if present, has been connected to the Master Unit 
•  different Master Units are connected each other via bus RS485 
 
After that, remember that only when all the remote units are already on, the Master Unit itself can be 
turned on. 
Once the Master Unit has been switched on, the TFLN behaviour at system start-up can be summarized 
as per the following steps: 
 

1.  When Master Unit is turned on all the six LEDs upon the TFLN front panel go on for a couple 

of seconds. After that, the green LED remains on (indicating proper power supply) while the 
other LEDs indicate the local unit status, according to the following table.
