Operational Modes

There are several different operational modes, which have different states controlled by

the cellular SW. Some examples are: Idle State (on ACCH), Camping (on DCCH), Scanning,

Conversation, and No Service Power Save (NSPS).

• Power-off mode = Only the circuits needed for power-up are supplied.

• Sleep mode = Circuits are powered down and only the 32kHz sleep clock runs. In

slotted mode or idle mode (a combination of sleep mode and receive mode), some

circuits turn on during the wake-up slot to receive page messaging from the base

station.

• Active mode = All circuits are supplied with power, although some parts might be

in idle state part of the time.

• Charge mode = Effective in parallel with all previous modes. The charge mode

itself consists of two different states, the fast charge and the maintenance mode.

• Local mode = Used for alignment and testing.
