Selectable functions of the mainboard DSP
The DSP on the mainboard provides selectable functions. A description of the individ-
ual functions can be found as of page 51.
The functions are determined in the
Media resources
(
=ym
) view. In the following ta-
ble, all the possible combinations are listed, with the maximum number of channels.
For this the DSP chip on the mainboard has to be loaded with different firmware. Addi-
tional functions require the use of one or more DSP modules. Some of these functions
are subject to a licence.

Notes
– To be able to configure VoIP channels on the mainboard’s DSP, make sure that in the
Media
resources
(
=ym
) view the
VoIP mode
parameter is set to
G.711
.
The configured VoIP mode is valid for all the DSP chips of a node. The following also applies
to this mode:
- 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).
– 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 mod-
ules. The number and position of the available slots are described in the chapter "Inter-
faces, display and control elements", page 47).
3. 3. 1
System modules
With system modules a distinction is made between modules expandable as an option
(DSP modules) and mandatory modules (CPU module, RAM module). This chapter
describes only the system modules that can be expanded as an option. They expand
