The GS3050-A provides 4 Alarm channels for SMS
and Telephone Dialler functions. These channels
refer respectively to terminals 15, 16, 17 and 18
(L1, L2, L3 and L4), and can be activated by Posi-
tive signals (transition from M
Negative signals (transition from positive to M
Use the on-board Jumpers P2 [17] and P3 [18] to
set the standby polarity of Input pairs L1-L2 and
L3-L4 (refer to Table 2). This setting is strictly
linked to the Input standby polarity (refer to "PRO-
GRAMMING THE SIM VIA PC" or "PROGRAM-
MING THE SIM VIA CELLPHONE"). In position a

OPERATING PRINCIPLES

The GSM Interface facility takes priority over the
Dialler facility (Voice and SMS). Therefore, if a
line-sharing device (connected downstream to
the Interface) requires the line, any ongoing cal-
ls/communications (Voice or SMS) will be inter-
rupted, and the calls from the line-sharing device
(e.g. Security system) will be sent. When the line-
sharing device hangs up, the Dialler facility (Voi-
ce or SMS) will restart the calls/communications.
NOTE - SMS Communication facility takes
priority over Voice Call facility. Therefore,
SMS texts will be sent before Voice calls.

GSM INTERFACE FACILITY

This operating mode will allow all calls and data
transmissions to be carried on the PSTN line du-
ring standby status. However, when the voltage
on the PSTN line (terminals LE) drops below 3 V
for a period ranging between 10 to 45 seconds
(the time depends on the device that is connected
to terminals LI), the GS3050-A will simulate the
