Overview of operating modes
Normal operation
GSM IDLE
Software is active. Once registered to the GSM network
paging with BTS is carried out. The Terminal is ready to
send and receive. Watchdog active.
GSM TALK
GSM DATA
Connection between two subscribers is in progress.
Power consumption depends on network coverage indi-
vidual settings, such as DTX off/on, FR/EFR/HR, hop-
ping sequences, antenna. Watchdog active.
GPRS / UMTS / HSPA
IDLE
Terminal is ready for GPRS data transfer, but no data is
currently sent or received. Power consumption depends
on network settings and GPRS configuration (e.g. multis-
lot settings). Watchdog active.
GPRS DATA
GPRS data transfer in progress. Power consumption
depends on network settings (e.g. power control level),
uplink / downlink data rates, GPRS configuration (e.g.
used multislot settings) and reduction of maximum out-
put power. Watchdog active.
EGPRS DATA
(EHSxT only)
EGPRS data transfer in progress. Power consumption
depends on network settings (e.g. power control level),
uplink / downlink data rates, EGPRS configuration (e.g.
used multislot settings) and reduction of maximum out-
put power. Watchdog active.
UMTS TALK
UMTS DATA
(EHSxT only)
UMTS data transfer in progress. Power consumption
depends on network settings (e.g. TPC Pattern) and data
transfer rate. Watchdog active.
HSPA DATA
(EHSxT only)
HSPA data transfer in progress. Power consumption
depends on network settings (e.g. TPC Pattern) and data
transfer rate. Watchdog active.
Power Down
Normal shutdown after sending the AT^SMSO command.
The RTC works continuously, but the software is not active. Interfaces are not
accessible.
Watchdog continues to operate, depending on its configuration.
