Function
Normal Operation
Active
In active mode, all functions of the module are available and all
processors are active. Radio transmission and reception can be
performed. Transitions to idle mode or PSM can be initiated in active
mode.
Idle
In idle mode, the module is in light sleep and network connection is
maintained; paging messages can be received; transitions to active
mode or PSM can be initiated in idle mode.
PSM
In PSM, only the 32kHz RTC is working. The network is disconnected,
and paging messages cannot be received either. When MO (Mobile
Originated) data are sent or the periodic TAU (Tracking Area Update)
timer T3412 expires, the module will be woken up.
