STLS4R 
 
NOTE  
Danger of damage to property due to surge voltage. The required lightning protection measures must be taken for this board, see Section 2.1.2 "Lightning Protection".  

Introduction  
The STLS4R (Subscriber And Trunk Line S0 RACK) board provides four S0 basic rate accesses for HiPath 3500 and HiPath 3300 (19-inch housing). These are operated either as external trunk interfaces in TE (terminal equipment) mode or as internal S0 buses (PMP bus) in NT (network terminator) mode with cross-connected RX-TX lines.
The board does not supply terminals with power; In this case, power must be supplied locally using a local plug-in power supply or a bus power supply unit, for example.
