System modules
System modules expand the resources of the basic systems, allowing the system to
be expanded step by step in line with requirements.

DSP module
Some system functions require additional signal processing capacity. This is
achieved using DSP modules (DSP stands for Digital Signal Processor). DSP mod-
ules increase the DSP capacity of the basic systems.

Design of the DSP module
DSP modules belong to the category of system modules 1 and are fitted to the SM1
slot (see
). The modules are stackable.
Note
The SM1 and SM2 slots are not identical (the space between the two con-
nector rails is different). Fitting DSP modules on the SM2 slot is thus not
mechanically possible.

Allocatable functions
One or more functions can be allocated to the individual DSP chips on the DSP
modules. For this the DSP chips have to be loaded with different firmware. The DSP
resources can be used for DECT telephony, Voice-over-IP, Voice Mail, hands-free op-
eration, integrated GSM users or fax transmissions. This means that for each DSP
chip a specific number of voice channels is available for the corresponding func-
