b. Leds on the front
Si tous fonctionnent correctement, la ou les DEL vertes sont allumées et clignote de manière régulière sur la
face avant du Linkgate ISDN. En communication celle-ci devient fixe.
Signalisation
Signification
Green LED flashing
Gateway is in std by mode
Green LED solid ON
Gateway is in communication
Red LED is ON
There is a problem on the gateway
When a red LED flashing on the front face, then there is a problem w ith the gatew ay. It is possible
to create a file w hich w ill contain all information making it possible to diagnose the problem, to
generate this file, click on the button "test" of the GSM set panel.
The program w ill open in a new window all information relating to the gatew ay. It is possible to
copy to stick and to print this test.

Possible problems when putting into operation
Here bellow find the current .
Problem
Solution
No LED are lit up
Power supply error. Check connection to the mains and connection
of the mains’ adapter to the gate
Quick “logging in” flashing of the red
LED has not occurred.
The module is not logged in the network:
Defective SIM card (or the card is incorrectly inserted in its
compartment)
Obsolete 5V SIM card (the module supports cards for 3V and
lower voltage);
Logging in GSM with PIN has been set and the PIN has not
been set in the gate by the positioning routine;
GSM signal is too weak.
The device is operating, however, the
call contains a humming sound
.
Unsuitable positioning of the aerial with respect to any of the
analogue telephone lines or an analogue telephone apparatus into
which GSM transmission is induced (identical as in case of a car
radio). It is necessary to test mutual position or totally relocate it.
The device is operating, however, an
“echo” can be heard in the call.
Echo is automatically eliminated by electronic means in the gate. If
you hear a beep despite this measure, it could be caused by:
Too improper impedance adaptation of the BTS channel to
which either you or your counterpart are connected;
Mobile telephone, which you are calling (some older types,
some types of protective cases).
Operation of GSM1,2 modules (green):
LED is flashing – module logged in the network, rest
condition
LED lit up permanently – connection in process (call)
Indication of error conditions in channels (red):
LED extinguished – rest condition
LED is flashing – error (more detailed information on
the error can be f ound out by listing conditions after
depressing the “test” pushbutton in the positioning
routine – see below)
