CelluLine CGW-T Installation and Programming Manual 1
1 Introduction
ITS is introducing the GSM Gateway – CelluLine CGW-T, a GSM cost reduction tool.
In a period, in which companies focus on cost reduction (without influencing the integrity of
the company), the CelluLine CGW-T will play an important role. The unit directly connects
your PBX to the GSM network, eliminating the excessive interconnection fees, thus cutting
your telephone costs significantly.
The CGW-T is connected to the analog trunk interface of the PBX. The
Automatic Route Select Table (ARS) in the PBX defines which calls will
be automatically routed via the CGW-T to the pre-defined GSM network.
In doing so, the CGW-T gateway reduces the company’s telephone costs.
Installation of the CGW-T does not require special skills. Simply insert
the SIM card, connect the unit to the PBX trunk interface, attach the
antenna and power supply and your CGW-T can immediately start saving
money for you. The unit has an LCD display, which shows the GSM
operator’s name, the signal strength and other useful call progress
information.
A number of additional parameters for the CGW-T, such as Output Audio
Volume level setting, Conversion time-out and Restricted Digits, can be
programmed via DTMF.

2 Pre-Installation
The CelluLine CGW-T unit contains a GSM engine. It therefore needs a SIM card from the
local GSM network provider. Its registration to the GSM operator is similar to the registration
of a mobile GSM phone.
The PIN & PUK code request must be disabled. Is this not the case, use any GSM mobile
phone to modify the SIM card or contact the local GSM Service Center.
Recommendation
We recommend disabling all call forwarding modes (in the events of busy, absence,
unavailability, etc.) and Call Waiting from the GSM operator, before installing the SIM card.

3 Installation
3.1 SIM Card Insertion in the CelluLine CGW-T Unit
Caution
To avoid damage to the CelluLine CGW-T unit, the 9V adapter should be disconnected from
the electric power-outlet.
The physical description of the unit can be used as guideline for the following steps:
• Hold the unit in your hands with the display pointed to your left and the SIM insertion
slot at the bottom of the unit towards you. (The text SIM will be upside-down!)
• Use a pointed screwdriver to push the yellow SIM release lever, so that the SIM card
tray moves towards you.
• Take out the tray. You will see that the SIM card will fit in the tray in one way.
• Now carefully place the tray with the SIM card in the slot and slide it in with the SIM
card contacts facing down.

3.2 CelluLine CGW-T Installation
• Mount the CelluLine CGW-T unit on the wall as a stand-alone unit or on the 6-fold wall
mount bracket, which is a separate accessory.
• Connect the Antenna into the Ant. connector on the side panel of the CelluLine CGW-T
unit.1
• Connect the analog trunk interface of the PBX to the trunk connector on the side panel of
the CelluLine CGW-T unit.
• Connect the power supply to the CelluLine CGW-T unit.
• The unit will start the initialization and registration. At the end of the process, the LCD
will display the GSM signal status.
Note:
1Experiment with the location of the antenna. The LCD gives an indication where you get the
best GSM reception.
The following figure gives a schematic representation of the CelluLine CGW-T unit setup.

4 LCD Status Indicators and Diagnostics
The CelluLine CGW-T GSM Gateway can be connected to the analog trunk interface of the
PBX. At power-up of the CelluLine CGW-T GSM Gateway unit, the information on the LCD
will provide the first diagnostics. In many cases further diagnostics is not needed. By
connecting an analog telephone with the RJ-11 connector to the trunk connector in the unit,
you are able to perform further diagnostics.
4.1 LCD Status Indicators
The following table shows the messages appearing on the LCD, their description and the
action to be taken (if any).

5 DTMF Programming
The CelluLine CGW-T GSM Gateway can be programmed via DTMF. The following steps
describe the procedure:
a. In case the CGW-T is connected to the PBX, remove the cable from the “Trunk”
connector on the unit.
b. Connect an analog telephone directly to the “Trunk” connector on the unit.
c. Dial *900.
d. After hearing the confirmation tone, enter the password (1234 by default).
Notes:
The CelluLine CGW-T will not answer any incoming calls when the analog telephone is
directly connected to the unit.
Exit from the programming mode by *900 or hanging up the telephone.
When you don’t enter digits for 45 seconds, the unit will automatically exit the programming
mode.
When entering an incorrect command, you will hear a beep.
When entering a correct command, you will hear two beeps.
