Introduction
The SLMA [SLMA24] and SLMA8 boards (Subscriber Line Module Analog) provide analog T/
R interfaces for use in HiPath 3800:
●
SLMA (S30810-Q2191-C300) = 24 analog T/R interfaces
●
SLMA8 (S30810-Q2191-C100) = eight analog T/R interfaces
Ring voltage
SLMA and SLMA8 boards generate their own ring voltage at 35 V
eff
. An external ring voltage
generator is therefore not required. If the generated ring voltage is too low for the connected
telephones, malfunctions may occur (for example, the MWI signal is not detected). To generate
higher ring voltage, the
board can be used in connection with the ring voltage generator

tion measures must be taken for this board, see Section 2.1.2, “Lightning Protec-
tion”.
