Call Manager card CPU1
The call manager card is the core the basic system and already fitted on delivery.
Besides a powerful processor it also comprises a RAM module, a Flash memory card
with the call manager software and an EIM card, on which the licences among oth-
ers are stored.
The call manager card comprises two powerful DSP chips, one of which can be as-
signed selectable functions. Two DSP modules can also be fitted as an option to
further boost the DSP resources (see also "DSP Resources", page 49).
An IP media module can be fitted as an option to increase the number of VoIP
channels (see also "IP media modules", page 58).
Three individually configurable Gbit Ethernet interfaces are available on the front
panel of the call manager card. The status of the interfaces is visible directly on the
interfaces themselves thanks to the LEDs (see also "Ethernet interfaces", page 166).
Analogue voice and data terminals are connected via FXS interfaces. The call man-
ager card comprises four of these configurable multifunctional interfaces (see also
"FXS terminal interfaces", page 146).
The most striking display element on the call manager card is the backlit 1.8” col-
our display with the four navigation keys as control elements. It is used to display
event messages or to execute maintenance functions. If the colour display is not
available (e.g. during call manager system setup) the call manager status is indi-
cated using the multi-coloured status LED on the On/Off button (see also "Display
and control panel of the call manager", page 240).
The figure below shows the positions of the interfaces and of the display and con-
trol elements on the call manager card.
