Inserting the SIM card
Before inserting or replacing the SIM card, always make sure that the
gateway has been disconnected from the mains and take all necessary
measures to avoid electrostatic discharge.
 Shift the SIM card housing cover downward until it unblocks and
lift it.
 Carefully slide the SIM card into its housing cover.
 Lower the SIM card housing cover and shift it upward until it
blocks.
WARNING
The SIM card PIN must be DISABLED. If the PIN is
enabled, it must be disabled through a mobile phone.
Inserting the antenna
 Screw the antenna cable in to the connector on the top of the
module.
WARNING
NEVER connect 3G.next gateway without having
previously installed the antenna. The gateway may get
damaged.
WARNING
Do not install 3G.next near other electric or electronic
devices that were not especially designed to be used
with it. They could be subjected to RF interference
from the module.

Page 11
 Position the antenna with magnetic base so that any metal
surfaces do not block the signal.
Connection to the telephone line
 Connect 3G.next to a standard telephone or to the PSTN input
terminals of a PABX or autodialer via the RJ-11 connector (H in the
picture at page 9);
or
 Connect 3G.next to a standard telephone or to the PSTN input
terminals of a PABX or autodialer using the TEL terminals (L in the
picture at page 9).

Page 12
Connection to the power supply
Power supply via 230Vac external adapter
 Connect the external adapter to the specific input (I in the picture
at page 9).
 Connect the backup batteries to the dedicated input (O in the
picture at page 9).
 Close the gateway cover.
or
12Vdc power supply
 Connect the power supply cable to the terminals M (in the picture
at page 9) taking care to respect the polarity.
 Connect the backup batteries to the dedicated input (O in the
picture at page 9).
 Close the gateway cover, paying attention to the power supply
cable.
WARNING
Backup batteries may be connected only after 3G.next
has been supplied
Note: the max voltage to be supplied to the mains terminals
M is 17Vdc.
Note: the min. voltage required to supply 3G.next gateway
by the mains terminals M is 10Vdc.
Note: a protection cut-out switch must be installed upstream
to interrupt power supply in case of fault.

Page 13
Turning the 3G.next gateway on
 Power 3G.next.
 Wait 30 seconds after power-up to give time to 3G.next to register
correctly with the UMTS/GSM network.
 Make sure the red LED (device status) flashes briefly once every 3
seconds as shown in chapter “Signals” (see page 60).
If the red LED flashes quicker and stays lit for a longer time (see page 60), the
gateway has not properly registered with the UMTS/GSM provider:
 Disconnect 3G.next and make sure the SIM card is inserted
correctly and that the PIN is not locking it.
 See chapter “Problem-detection guide” (page 62).

Page 14
Gateway mounting operations
 Check the UMTS/GSM signal strength through the green indicator
LED (see chapter “Signals”, page 59) and identify an area where
the signal is strong enough.
Note: the signal strength may vary according to the
telephone provider.
 Drill two holes with 5 mm diameter on the wall at a distance of 50
mm.
 Insert the 2 wall plugs and screws down until the screws are at a 5
mm distance from the wall.
 Place 3G.next gateway onto the two screws through the two back
slots.

Page 15
3G.next installation recommendations
 3G.next gateway must be installed in a location where the radio signal
allows for using the UMTS/GSM system.
 It is advisable to leave plenty of space around the gateway for
maintenance operations.
 Do not install 3G.next gateway outdoors, since it lacks protection
devices against weather conditions that can damage the gateway (water,
humidity, etc.).
 Do not install 3G.next gateway near electronic (radio or TV sets,
Personal Computers, wired radio systems, etc.) or magnetic (credit
cards, etc.) devices that could be subjected to RF interference from the
module: recommended distance from the antenna is min. 2,5 m.
 Do not install 3G.next gateway near medical devices. Its operation may
cause damage to hearing aids or pacemakers.
 Always make sure that the device operation is permitted in the place of
installation (e.g. installation is not allowed in hospitals, airplanes, etc.).

PROGRAMMING VIA
TELEPHONE
Allows you to customise the gateway according to your requirements.
Programming can be carried out locally via a MF telephone.
You can programme:
 voltage of telephone line;
 use mode;
 inter-digit dialling time;
 country settings (country calling code and international call prefix);
 CLIP/CLIR settings;
 roaming service settings;
 provider's voicemail service deactivation;
 notifications telephone number;
 administrator telephone number ;
 programming-mode password;
 battery check;
 external power failure control;
 relay-based notification of external power failure;
 relay-based notification of UMTS/GSM network loss;
 automatic converter of selected telephone number;
 receiver gain adjustment;
 transmitter gain adjustment;
 relay settings.
Note: during programming, the inter-digit dialling time must
not exceed 10 seconds. Once 10 seconds has elapsed
without digits you will hear the dissuasion tone and
you will have to hang up.
Note: at the end of each programming carried out correctly,
you will hear a confirmation tone, while an error tone

Page 17
will be heard in case of error. In any case, the
dialling tone will follow, after which you can proceed
with the programming or make a call.
Note: programming can be carried out even if the signal is
absent. After the confirmation or the error tones, he
dissuasion tone will follow, after which you can
proceed with programming or hang up.
TELEPHONE LINE VOLTAGE
The following programming allows you to modify the voltage in the TEL
terminal and in the RJ-11 connector. A higher voltage may be required
for the proper functioning of specific devices.
Factory default: higher voltage (52Vdc).
(option) (confirm)
 Lift the handset and dial: **61*.
 Enter:
0 lower voltage (36Vdc);
1 higher voltage (52Vdc).
 Dial # to confirm.
 After the confirmation tone hang up or enter additional settings.

Page 18
USE MODE
3G.next delivers 4 different use modes which allow to improve
performance according to the specific devices being connected. They
should be selected in case the connected devices detect the telephone line
tones or when echo occurs during conversation.
Factory default: mode1.
Mode 1
Factory default.
(confirm)
 Lift the handset and dial: **21.
 Dial # to confirm.
 After the confirmation tone hang up or enter additional settings.
Mode 2
Use mode recommended for autodialers or other devices effecting tone
detection over the line.
(confirm)
 Lift the handset and dial: **22.
 Dial # to confirm.
 After the confirmation tone hang up or enter additional settings.
Mode 3

Use mode recommended to reduce echo in case of connection with
devices effecting tone detection over the line.
(confirm)
 Lift the handset and dial: **24.
 Dial # to confirm.
 After the confirmation tone hang up or enter additional settings.
INTER-DIGIT DIALLING TIME
The inter-digit time is the maximum amount of time allowed between
digits while dialling a telephone number.
There are 2 ways to make outgoing calls:
 Dial the telephone number and then press # to confirm. The call is
sent immediately.
 Dial the telephone number and wait. The call will be sent after the
inter-digit time has elapsed.
Factory default: 5 seconds.
(inter-digit time)
(confirm)
 Lift the handset and dial: **8*;
 Dial the inter-digit dialling time:
0 inter-digit time: 10 seconds;
1-9 inter-digit time from 1 to 9 seconds.
 Dial # to confirm.

Page 20
 After the confirmation tone hang up or enter additional settings.
COUNTRY SETTINGS
This programming allows defining the country of use of 3G.next, in order
to set automatically the device with the proper parameters (if available).
For example the tones of the call change and on the display of a telephone
connected to 3G.next the calling number is shown without the area code.
International call prefix
The international call prefix is the first part of a country’s code. For
example, the international dialling code for Italy, whose complete code is
0039, is 00.
Factory default: 00.
... (international call prefix) (confirm)
 Lift the handset and dial: **08*;
 Dial the international call prefix (max. 5 digits).
 Dial # to confirm.
 After the confirmation tone hang up or enter additional settings.
Country calling code
The country calling code is the second part of a country’s code. For
example, the country calling code for Italy, whose complete code is 0039,
is 39.
Factory default: 39.
... (country calling
code) (confirm)
