RGMOD (for selected countries only) 
 

Introduction  
The external ring voltage generator RGMOD (S30124-X5109-X) is required for generating ring voltages for the HiPath 3800 SLMA2 board. RGMOD is plugged in on the reverse of the backplane of the basic and/or expansion cabinet.
Danger  
RGMOD must not be plugged in or out when the system is energized!  
In normal mode, the ring voltage generator operates with voltages ranging from +75 V to -170 V. The prescribed measures for protection against high voltage must be taken when working on or close to the board.  
When the ring voltage generator is removed, no ring tone is generated for the analog telephones connected to the SLMA2.  
A system cabinet can be fitted with a mix of SLMA, SLMA8 and SLMA2 boards. RGMOD has no effect on SLMA and SLMA8, as these boards generate their own ring voltage (35 Veff).  

Setting the ring voltage and ring frequency  
The ring voltage and ring frequency are set using jumpers.

Installing RGMOD  
The RGMOD ring voltage generator is plugged in at the rear of the backplane.
 •   Basic cabinet
When using one or more SLMA2 boards in the basic cabinet, RGMOD must be plugged into the 10-pin port X214 of the basic cabinet (see Figure 3-22).
   
   Figure 3-22   HiPath 3800 - Connectors and Jacks on Backplane of Basic Cabinet
 
 •   Expansion cabinet
When using one or more SLMA2 boards in the expansion cabinet, RGMOD must be plugged into the 10-pin port X214 of the expansion cabinet (see Figure 3-23).
