DSP Cards DSP-01 and DSP-02
DSP cards contain the hardware required for operating DECT radio units on AD2
interfaces.
The DSP-02 DSP card also enables full duplex hands-free operation on Office 45
terminals. This increases the quality during hands-free mode. On all Office termi-
nals with hands-free mode, half-duplex hands-free mode is also possible without
the DSP-02 DSP card.
