O General Output PIN. If not use, left
open. It also can be multiplex as the
PCM_SYNC pin.
I RF Control: Flight Modem switch
O General Output PIN. If not use, left
open. It also can be multiplex as the
PCM_OUT pin.
Module will go into Power off mode when the Power_on pin
has been pushed to low for 2 Seconds.
Module will automatically go into sleep mode when no
interrupt input or other operation.
In this case, the current consumption of module will reduce to
the minimal level.
Software is active. Module has registered to the GSM network,
and the module is ready to send and receive.
CSD connection is going on between two subscribers. In this
case, the power consumption depends on network settings
such as DTX off/on, FR/EFR/HR, hopping sequences,
antenna.
Module is ready for GPRS data transfer, but no data is
currently sent or received. In this case, power consumption
depends on network settings and GPRS configuration (e.g.
multi-slot settings).
There is GPRS data in transfer (PPP or TCP or UDP). In this
case, power consumption is related with network settings (e.g.
power control level), uplink / downlink data rates and GPRS
configuration (e.g. used multi-slot settings).
Module is ready for data transfer in EDGE mode, but no data
is currently sent or received. In this case, power consumption
depends on network settings and EDGE configuration
There is data in transfer (PPP or TCP or UDP) in EDGE mode.
In this case, power consumption is related with network
settings (e.g. power control level), uplink / downlink data rates
and EDGE configuration.
