TLA4R (not for U.S.) 
 
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 TLA4R (Trunk Line Analog Rack) board provides four ports for the analog trunk connection (DP and DTMF signaling methods) on HiPath 3500 and HiPath 3300 (19-inch housing). There are also two ALUM power failure transfers.
The transmission and function-oriented characteristics of the TLA4R are completely identical to those of the TLA boards that are used in HiPath 3550 and HiPath 3350. The only differences are
 •   the two ALUMs which are only available on the TLA4R.
 •   the call metering receiving equipment interface, which is only on the TLA boards.
