ME is in one of the following modes: -POWER
DOWN mode
AIRPLANE mode
CHARGE ONLY mode
600 ms on / 600ms off
Limited Network Service: No SIM card
inserted or no PIN entered, or network
search in progress, or ongoing user
authentication, or network login in progress
Same as for AT^SSYNC=1
75 ms on / 3 s off
IDLE mode: The mobile is registered to the
GSM network (monitoring control channels
and user interactions). No call is in progress.
Same as for AT^SSYNC=1
75 ms on / 75 ms off / 75
ms on / 3 s off
One or more GPRS PDP contexts activated.
Same as for AT^SSYNC=1
500 ms on / 50 ms off

Permanently on
Depending on type of call: Voice call:
Connected to remote party. Data call:
Connected to remote party or exchange of
parameters
while
setting
up
or
disconnecting a call.
Same as for AT^SSYNC=1
<n> ms on / <n> ms off
(2)
Not possible: With AT^SSYNC=1, LED
signalization is disabled in SLEEP mode.
SLEEP
mode
is
activated
(AT+CFUN
parameter <fun>≠ 1), but the ME is not
registered to the GSM network (e.g. SIM not
inserted or PIN not entered, and therefore,
either no network service or only Limited
Network Service is avail-able.
1) When a temporary wake-up event (for example a call, a URC, a packet switched transfer) occurs in CYCLIC SLEEP mode
the LED flashes according to the patterns listed above. See Section 2.9.1, Wake up the ME from SLEEP mode for details
on the various SLEEP modes and wake-up events.
2) The duration of <n> and <m> depends on the network: In SLEEP mode, the module can only change its LED status during
intermittent wake-up periods when listening to paging information from the base station. Therefore the values of <n> and
<m> vary as follows:
<n> = value from 471 ms to 2118 ms
<m> = 3000 ms
