 URC 1

^SYSSTART

Indicates that the ME has been started and is ready to operate. If autobauding is active (

=0) the URC

is not generated. 

If the ME is configured to enter the Airplane mode after restart or reset the following URC is received on boot-

up: "

". In this mode, only the AT commands listed in Section 

 can be used. For details please

refer to the 

 command, parameter 

. 

 URC 2

^SYSSTART CHARGE ONLY MODE

Indicates that the ME has entered the CHARGE ONLY mode. This occurs if the charger is connected while

the ME is in POWER DOWN mode. If autobauding is active (

=0) the URC is not generated. In

CHARGE ONLY mode the ME is neither registered to the GSM network nor are the serial interfaces fully

accessible. Only the AT commands listed in Section 

 can be used. For further details on charging refer to the Hardware Interface

0

NON-CYCLIC SLEEP mode: 

In this mode, the AT interface is not accessible. Consequently, after setting

=0, do not send further characters. Otherwise these characters remain

in the input buffer and may delay the output of an unsolicited result code. 

Due to the fact that the serial interface is disabled, this mode cannot be used

if a Remote SIM Access (RSA) connection is ongoing (reason: during RSA

connections the SIM communication is routed via a serial channel).

The first wake-up event stops power saving and takes the ME back to full func-

tionality level 

=1. 

[1]

(&F)(P)

Full functionality (no power saving). 

If the ME is in one of the CYCLIC SLEEP modes you can issue AT+CFUN=1

to stop power saving and return to full functionality. If the ME is NON-CYCLIC

SLEEP mode, 

=1 can also be sent by the Java application. 

Keep in mind that, unlike the reset command described below, this action does

not restart the ME but only changes the level of functionality. See parameter

 for details on the reset. 

7

CYCLIC SLEEP mode: 

In this mode, the serial interface is shortly enabled while CTS is active. If char-

acters are recognized on the serial interface, the ME stays active for 2 seconds

after the last character was sent or received. 

The ME exits SLEEP mode only, if 

=1 is entered.

9

CYCLIC SLEEP mode: 

In this mode, the serial interface is shortly enabled while CTS is active. If char-

acters are recognized on the serial interface, the ME stays active after the last

character was sent or received for at least the time, which can be configured

="PowerSaver/Mode9/Timeout",

 (temporary wakeup). 

In contrast to SLEEP mode 7 assertion of RTS can also be used to temporarily

wake up the ME. In this case too, activity time is at least the time set with

="PowerSaver/Mode9/Timeout",

. RTS can be activated

either from ASC0 or ASC1.

The ME exits SLEEP mode only, if 

=1 is entered.
