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 1410 ms to 2360 ms
<m> = value from 2110 ms to 3770 ms
75 ms on / 3 s off ME is registered to the GSM network
(monitoring control channels and user
interactions). No call is in progress.
ME is in full functionality mode
(
AT+CFUN= 1) or in a "temporary wake-
up state" after characters have been
detected on the serial interface in
CYCLIC SLEEP mode. The AT interface
is fully accessible.
As for AT^SSYNC parameter <mode>= 1
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.
As for AT^SSYNC parameter <mode>= 1
<n> ms on / <n> ms off Not possible: With AT^SSYNC=1, LED
signalization is disabled in SLEEP
mode.
SLEEP mode is activated (AT+CFUN
parameter
<fun> ¹ 1), but power saving
does not work because 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.
Approx. 15 ms on /
<m> ms off
Not possible: With AT^SSYNC=1, LED
signalization is disabled in SLEEP
mode.
SLEEP mode is activated (AT+CFUN
parameter
<fun> ¹ 1) while the ME is
registered to the GSM network. Power
saving is properly enabled.
