or SM-DSP2
Notes
– To configure VoIP channels on the DSP chip of a DSP module, make
sure the (
=ym
)
VoIP mode
parameter in the DSP configuration is not
set to
No VoIP
. With the exception of the IP media modules the config-
ured
VoIP mode
applies to all the DSP chips of a node. If
VoIP mode
is
set to
G.711
, two G.711 VoIP channels per system can be used without
a licence. The G.711 VoIP channels of the configurable DSP chip on
processor card CPU1 can be combined with G.711 VoIP channels of
DSP modules.
– If audio channels are configured and licensed, the two basic audio
channels that can be used without a licence are redundant (see
).
– Audio channels and FoIP channels can only be configured on one DSP
chip per node.
– The system has to be restarted for the configuration changes of the
DSP to take effect.
– After a first start all the DSP chips are configured on
DECT
.
