Power supply

The system is powered as standard with 230 VAC or 115 VAC using the supplied
power supply. The communications server is powered with 19V DC from the power
supply. All other voltages are generated directly on the mainboard. To ensure that its
operation is maintained even in the event of a mains outage, an external uninterrupti-
ble power supply (UPS) must be used. For more details about the power supply see
"Powering the communication server", page 95.

Media resources

Media resources are used for complex signal processing functions, and made availa-
ble by DSP chips. (DSP stands for Digital Signal Processor). They provide functions for
conference circuits, DTMF sender and receiver, compression of voice data, etc. A DSP
chip is fitted permanently to the mainboard.
Part of these media resources is allocated to fixed functions and can be used without li-
cences (see Tab. 15).
Another part is allocated to selectable functions, according to requirements. These
functions are partly subject to licence (see Tab. 16).
The basic resources of the communication server can be expanded by fitting DSP
modules. The functions of the DSP chips on the modules can also be configured (see
Tab. 23 and Tab. 22).
Fixed functions of the mainboard DSP
The table below provides an overview of the fixed functions of the mainboard DSP. No
licences or additional hardware is required to use the functions.
