TLDN Installation
Since the TLDN module doesn’t require any power supply, it can be housed either in an active
or a passive TPRN sub-rack.
1. Unpack the kit which includes
ÿ 1 TLDN
ÿ 2 RF jumpers (SMA-m), 2 x 40 cm
2. Carefully insert the TLDN module in any of the TPRN sub-rack slots and tighten the 4 screws
on the front corners.
3. Connect RF cables to the UL and DL ports, according to what has been planned by the
designer. Use an appropriate torque wrench to fi x each cable to their relevant ports.
