REALS 
 
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 REALS (Relay and ALUM for SAPP) board is used in HiPath 3800 to provide the following functions:
 •   Four individual, controllable relays are available for special connections, such as door openers.
The switch contacts for all relays are floating and protected by surge protectors.
    Electrical characteristics of the relays are as follows:
   -   Maximum current drain at - 48 V: 80 mA
   -   Operating voltage: + 5 V
   -   Contact current: max. 1.25 A
   -   Contact power: max. 30 W
 •   Trunk failure transfer (ALUM)
In the event of a power failure or a system restart or reload, an analog trunk is transferred from the system to an analog telephone. If the power supply voltage returns after an interruption and a trunk call is in progress, activation of the trunk failure transfer relay is prevented by optocoupler.
   -   Default = HiPath 3800 is in normal mode:
     PFTALa/b (trunk) is connected to PFTASa/b (trunk module).
     PFTTLa/b (terminal) is connected to PFTTSa/b (subscriber line module).
   -   Error = HiPath 3800 does not have any power
     PFTTLa/b (terminal) is connected to PFTALa/b (trunk).
    ALUM relay electrical data:
   -   Operating voltage: + 5 V
   -   Contact current: max. 1.25 A
   -   Contact power: max. 30 W
All of the functions are controlled by the CBSAP board.
Two -48-V lines fused using a PTC resistor are available for external applications. The voltage is picked up via MDFU-E (Table 3-186: M48VF1 / 0V_F and M48VF2 / 0V_F). Each trunk has a maximum load capacity of 300 mA.

Slot  
Insert the REALS board into the slot marked 3 in the lower part of the shelf in the basic cabinet and apply pressure until you hear a click (see Figure 4-21).
The slots for the power supply units and for the REALS board must be covered with an outer panel before the system is started up. The outer panel is fixed onto the shelf with screws (see Figure 3-154).

Cable and connector assignment  
Table 3-186 shows the assignment of the SIVAPAC connector X116 on the backplane and the assignment of the jumper strip in the MDFU-E.
