RGMOD (for selected countries only)

The external ring voltage generator RGMOD (S30124-X5109-X) is required for generating ring
voltages for the HiPath 3800
plane 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,

MOD has no effect on SLMA and SLMA8, as these boards generate their own ring
voltage (35 V
Setting the ring voltage and ring frequency
The ring voltage and ring frequency are set using jumpers.
