Fig. 44 Power available B on the DSI-AD2 bus
Notes
– If another system phone is operated on the DSI-AD2 bus in addition to an MiVoice 5361,
MiVoice 5370 or MiVoice 5380, at least one phone must be powered by a local power supply
unit.
– An MiVoice 5370 or MiVoice 5380 with an MiVoice M535 expansion key module always
requires a power supply unit.
– An MiVoice 5380 with 3 MiVoice M530 expansion key modules always requires a power
supply unit. With 2 expansion key modules the use of power supply unit depends on the line
length and the line cross-section.
