RGMOD (for selected countries only)

Introduction
The external ring generator RGMOD (S30122-K5929-X) is required for the generation of ring
voltages for the HiPath 3800 board SLMA2. RGMOD is plugged in on the backplane of the ba-
sic and/or expansion cabinet.
Danger
7
RGMOD must not be plugged in or out when the system is energized!
In normal mode, the ring 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 generator is removed, no ring tone is generated for the analog tele-
phones connected to the SLMA2.
Setting the ring voltage and ring frequency
The ring voltage and ring frequency are set using jumpers.
