1 Introduction
Your new CGW-T is an analog GSM/CDMA Cellular Gateway (CGW-TS – GSM only), a
cost reduction tool for mobile-to-landline and landline-to-mobile calls. It connects from the
trunk interface (analog FXO) of your PBX to a GSM network (via the inserted SIM card) or
to a CDMA network (by the built-in CDMA engine), eliminating the excessive
interconnection fees and significantly cutting your telephone costs.
The Automatic Route Select table (ARS) in the PBX defines which calls will be automatically
routed via the CGW-T to the predefined GSM/CDMA network. In doing so, the CGW-T/TS
gateway reduces the company’s telephone costs.
Installation of the CGW-T/TS does not require special skills. Simply insert the SIM card
(GSM networks only), connect the unit to the PBX trunk interface, attach the antenna and
power supply, and your CGW-T/TS can immediately start saving money for you. The unit has
an LCD display, which shows the GSM/CDMA operator’s name (CGW-T only), the signal
strength and other useful call progress information.
A number of additional parameters for the CGW-T/TS, such as Output Audio Volume level
setting, Conversion time-out and Restricted Digits, can be programmed via DTMF.
The CGW-T and CGW-TS units are displayed in Figure 1.

3 Pre-Installation
3.1 GSM Gateway
The CGW-T/TS 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 and PUK code requests recommended to be disabled (see LCD Messages table,
below). If, for any reason, you are unable to do so using an analog telephone connected to the
CGW-T/TS FXS RJ-11 port, use any GSM mobile phone to modify the SIM card, or contact
your local GSM Service Center.
3.2 CDMA Gateway (CGW-T Only)
The CGW-T (CDMA) contains a CDMA engine that needs to be activated via a local CDMA
network provider. You register the engine the way you would normally register a mobile
CDMA phone.
NOTE
It is recommended that you disable all call forwarding modes (in the events of busy,
absence, unavailability, etc.) and Call Waiting from the GSM/CDMA operator, before
installing the SIM card (GSM network), or activating the CDMA unit.

contacts facing down.
4.2 CGW-T/TS Installation
To install the CGW-T/TS unit, perform the steps as follows:
Mount the CGW-T/TS 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 front panel of the CGW-T/TS unit.
Connect the analog trunk interface of the PBX to the trunk connector on the front panel
of the CGW-T/TS unit.
Connect the power supply to the CGW-T/TS unit. The unit will start the initialization
and registration. At the end of the process, the LCD will display the signal status.
NOTE
Figure 3 displays the schematic setup of the CGW-T/TS unit.
Adjust the antenna location until an optimal signal level is received.

5 LCD Status Indicators and Diagnostics
5.1 CGW-T LCD Status Indicators and Diagnostics
The CGW-T Gateway can be connected to the analog trunk interface of the PBX. At powerup of the CGW-T unit, the information on the LCD will provide the first diagnostics. Usually,
further diagnostics are unnecessary. By connecting an analog telephone with the RJ-11
connector to the trunk connector in the unit, you are able to perform further diagnostics.

5.1.2 CGW-T Diagnostics
Perform the diagnostic procedure as follows:
Connect an analog telephone directly to the trunk connector (RJ-11) on the unit front
panel.
Pick up the receiver and listen to the dial tone:
- A continuous dial tone indicates that the unit is working correctly and ready for
programming.
- A busy dial tone indicates that there is a fault. Check the LCD display for a
message.
NOTE
If there is no SIM card in the device, or if the card is not installed properly, there will
be no tone on the CGW-T, whereas on the CGW-D the tone will be that of the PSTN
line.

5.2.3 CGW-TS Diagnostics
Perform the diagnostic procedure as follows:
Connect an analog telephone directly to the trunk (FXS) connector (RJ-11) on the unit
front panel.
Pick up the receiver and listen to the dial tone:
- A continuous dial tone indicates that the unit is working correctly and ready for
programming.
- A busy dial tone indicates that there is a fault. Check which LEDs are lit and find
the error in the table in Paragraph
resolve the problem and hear a continuous dial tone.
- No dial tone indicates that the GSM network signal is too low to complete
registration. Remove your SIM card and replace it with a card from a GSM
network that provides a higher signal level. Enable the roaming parameter (see
command *500 in the programming table), and then replace the SIM card with your
original SIM card.
NOTE
All cellular calls you now make from your CGW-TS will be routed through the
alternate GSM network that you used to complete your registration.

6 DTMF Programming
The CGW-T/TS Gateway can be programmed via DTMF. To program the unit perform the
steps as follows:
a. If the unit is connected to the PBX, remove the cable from the Trunk connector on the
unit front panel.
b. Connect an analog telephone directly to the Trunk connector.
c. Dial *900 and enter the password (1234 by default).
d. Use the commands in the following table for programming.
NOTE
When DTMF programming changes are made, the device will perform an
automatic reset for the changes to take effect.
The CGW-T/TS will not answer incoming calls in the programming mode.
Exit from the programming mode by *900 or hanging up the telephone.
If you do not 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.
