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
. The setting is valid for 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 mainboard 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
Tab. 15
).
– Audio channels and FoIP 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.
– After a first start all the DSP chips are configured on
DECT
.

Interface cards
Interface cards can be assigned to three categories:
• Trunk cards
These cards provide interfaces for connection to public dial-up networks or for
networking systems to create a private telephony network.
• Terminal cards
These cards provide interfaces for connecting digital and analogue voice and
data terminals.
• Options cards
This category comprises the ODAB card, the interfaces for connecting a door in-
tercom, for controlling external devices, and for switching over internal switch
groups.
On some cards some of the interfaces are configurable (BRI-S/T). This means that
these cards cannot be clearly assigned to any particular category. They are listed
both among the trunk cards and the terminal cards.
Interface cards are fitted into slots IC1...IC4 (see
Fig. 7
).
The interfaces are routed to the front panel using the Wiring Adapters (see
"Wiring
Adapter", page 54
).
