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
25 ms on / 4 * <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) while the ME is
registered to the GSM network and in
IDLE mode.

Not possible: With AT^SSYNC=1, LED
signalization is disabled in SLEEP
mode.
SLEEP mode is activated (AT+CFUN
parameter <fun> ≠ 1) while the ME is
registered to the GSM network. Addi-
tionally, PDP context is activated.
