- Two G.711 VoIP channels per system can be used without a licence.
- The G.711 VoIP channels of the mainboard can be combined with
G.711 VoIP channels of DSP modules.
– If voice mail channels are configured and licensed, the two G.711 basic
voice mail channels that can be used without a licence are redundant
(see
Tab. 15
).
– Voice mail channels can only be configured on one DSP chip per node.
– The
Modem
function is used for remote maintenance via an analogue
modem and can only be configured on the mainboard’s DSP.
– The system has to be restarted for the configuration changes of the
DSP to take effect.

Expansion with cards and modules
A basic system can be individually expanded using interface cards and system
modules. The number of available expansion slots depends on the type of the basic
system (see
"Interfaces, display and control elements", page 39
).
3. 3. 1
System modules
System modules expand the resources of the communication server, allowing the
system to be expanded step by step in line with requirements.
3. 3. 1. 1
DSP modules
Processor-intensive system functions require DSP resources. The communication
server’s DSP capacity increases through the use of DSP modules.

Design of the DSP module
DSP modules belong to the category of system modules 1 and are stacked to the
SM1 slot (see
Fig. 7
). The different types of modules can be used as a mix.
