3.15 Jamming Indicator
The GPIO6 interface line can be configured as a jamming indicator by AT command. When
possible jamming is detected by the module, GPIO6 is set to high level. This state lasts as
long as possible jamming is detected.
By default, the jamming indicator feature is disabled. It has to be enabled using the AT com-
mand AT^SCFG "MEopMode/JamDet/If". For details see [1].
3.16 Status LED
The GPIO5 line at the SMT application interface can be configured to drive a status LED which
indicates different operating modes of the module (for GPIOs see Section 3.13). GPIO and LED
functionality are mutually exclusive.
To take advantage of this function connect an LED to the GPIO5/LED line as shown in Figure
32. The LED can be enabled/disabled by AT command. For details refer to [1]: AT^SSYNC.

3.17 Behavior of the RING0 Line (ASC0 Interface only)
The RING0 line is available on the first serial interface (ASC0). The signal serves to indicate
incoming calls and other types of URCs (Unsolicited Result Code).
Although not mandatory for use in a host application, it is strongly suggested that you connect
the RING0 line to an interrupt line of your application. In this case, the application can be de-
signed to receive an interrupt when a falling edge on RING0 occurs. This solution is most
effective, particularly, for waking up an application from power saving. Note that if the RING0
line is not wired, the application would be required to permanently poll the data and status
lines of the serial interface at the expense of a higher current consumption. Therefore, uti-
lizing the RING0 line provides an option to significantly reduce the overall current consump-
tion of your application.
