Table 2
Powering the i2022 Locally
The
i
2022 can use a significant amount of power, especially when equipped with EM-32 Add-On Call Appearance
modules. Back light, speakerphone, and DSS/BLF settings can significantly add to the power draw of the
i
2022. In these
high power consumption modes, it is desirable to power the
i
2022 locally. Figure 4 shows a method of powering the
i
2022
using a Lucent 1215B Power Supply.
