Attention! If SIM memory is full and a further SMS is received, the
oldest one will be erased in order to unblock the path for switch
control commands. If switches are not used, erasing can be disabled
by parameter 109, see chapter 6.1.
2.5. Power Supply Connection
•
Make sure that the voltage in your mains corresponds with the data on the product label.
•
Make sure that the antenna has been connected.
If you connect a power supply to the
equipment without the antenna, you might cause damage to the GSM module
transmitter.
•
Connect your power cord. After a while, the green indicator “AC Supply O.K.” should go on.
2.6. Functional verification
Recommendation: check GSM gateway functionality prior to connecting it to your PBX and
programming.
1. Connect GSM gateway to previously checked telephone set. Verify that this telephone is
switched to DTMF and its ringer is ON. If is better to check a SIM card too, using a mobile
phone. It is not necessary to fix GSM gateway to a wall for testing – it can lie on flat surface
as well. Excepting this, follow chapters 2.2 to 2.5 to connect all needed.
2. If the inserted SIM card requires a PIN, the red lamp will light up. In this case, pick up the
handset of connected a phone. You will hear a PIN tone
. Enter PIN as
described in chapter 3.6.2 and hang up, the red lamp will go out.
3. The GSM gateway will register itself into the GSM network. After a moment, the green
“GSM” lamp will light up.
4. Pick up the phone; you will hear the dialling tone
and the yellow “Line ready” lamp
will start blinking. If it doesn’t, the phone or its connection is bad.
5. Now check for signal quality. Enter programming mode according to chapter 5.3.2, skipping step
No. 1 (this applies only in the case of connection to a PBX). Indication of GSM signal quality will
be turned on automatically. As more lamps are lit, signal quality is better. If at least one green
lamp is lit up, signal quality is excellent. Try to find a good place for the antenna. Keep the
antenna vertical and move it slowly – signal quality information is updated every three seconds.
Remember that a movement as small as 10 cm may have a considerable effect on signal
quality, as well as a position close to your body. The best way is to step aside after each
relocating of antenna. Hang up after positioning the antenna; do not program anything!
6. Make an outgoing call. Call your colleagues mobile e.g. and verify that you hear each other
well. In the case of a completely new pre-paid SIM card, one outgoing call is necessary for
SIM card activation. Until it is activated an incoming call cannot be received! Make an
incoming call now. Call the GSM gateway; the phone should ring.
7. The GSM gateway is now checked. You can now connect it to a vacant C.O. line in the PBX.
After connection is completed, check both incoming and outgoing calls again. This may, of
course, necessitate some programming or settings changes of the PBX. If everything is
O.K., you can go to programming, if it is required - see chapter 5.
