1 Introduction
Your new CGW-T4 is an analog 4 ports GSM/CDMA Cellular Gateway, 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-T4 to the predefined GSM/CDMA network. In doing so, the CGW-T4
gateway reduces the company’s telephone costs.
Integrated with the PBX analog trunk interface CGW-T4 provides Reverse Polarity and Loop
disconnection signaling for to release disconnected call.
Installation of the CGW-T4 does not require special skills. Simply insert the SIM card (GSM
networks only), connect the unit to the PBX trunk interfaces, attach the antennas and power
supply, and your CGW-T4 can immediately start saving money for you. The unit has an LCD
display for each channel, which shows the GSM/CDMA operator’s name, the signal strength
and other useful call progress information.
A number of additional parameters for the CGW-T4, such as Output Audio Volume level
setting, Conversion time-out and Restricted Digits, can be programmed via DTMF separately
for each channel.

3 Pre-Installation
3.1 GSM Cellular Channels
The CGW-T4 unit contains a GSM engines. It therefore needs a SIM cards from the local GSM
network providers. Its registration to the GSM operator is similar to the registration of a
mobile GSM phone.
3.2 CDMA Cellular Channels
The CGW-T4 (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.

4 Installation
4.1 SIM Card Insertion into the Unit (GSM channels only)
CAUTION
1
The physical description of the unit can be used as guideline for the following steps:
SIM card’s holders can be found on the right and left lateral surfaces (See Figure 3 ). Each SIM
card holder marked with the corresponded cellular channel’s number
Using a screwdriver, push the yellow SIM release lever, so that the SIM card tray moves
towards you.
To avoid damage to the CGW-T4 unit, disconnect the 9V adapter from the electric power outlet.
Take out the tray. You will see that the SIM card fits in the tray in one way only.
Carefully place the tray with the SIM card in the slot and slide it in with the SIM card contacts
facing down.

4.2 CGW-T4 Installation
To install the CGW-T4 unit, perform the steps as follows:
Mount the CGW-T4 unit in the 19-inch rack or on the wall by using installation brackets
or place the unit on the horizontal surface.
Connect the antennas into the ‘Ant.’ SMA connectors on the front panel of the CGW-4
unit.
Connect the analog trunk interface of the PBX to the port sockets on the front panel of
the CGW-T4 unit.
Connect the power supply to the CGW-T4 unit. The unit will start the initialization and
registration. At the end of the process, the LCD’s will display the signal status of each cellular channel.
NOTE
Adjust the antenna location until an optimal signal level is received. The signal level indicates on the LCD display.

5 LCD Status Indicators and Diagnostics
5.1 CGW-T4 LCD Status Indicators and Diagnostics
The CGW-T4 Gateway can be connected to the analog trunks interface of the PBX or directly
to the analog home phone. At power-up of the CGW-T4 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 appropriate port’s socket in
the unit, you are able to perform further diagnostics.

5.1.2 CGW-T4 Diagnostics
Perform the diagnostic procedure as follows:
Connect an analog telephone directly to the required port socket (RJ-11) on the unit front
panel.
Pick up the handset 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 appropriate LCD display for a
message.

6 DTMF Programming
The CGW-T4 Gateway can be programmed via DTMF commands.
NOTE
To program the cellular channel perform the steps as follows:
Each Analog-Cellular channel required the separate programming procedure.
If the unit is connected to the PBX, remove the cable from the appropriate RJ-11 port
socket on the unit front panel.
Connect an analog telephone directly to the required RJ-11 port . (1,2,3 or 4) Pick up the handset, hear the dialtone and Dial *900 then enter the password (1234
by default).
Use the commands in the following table for programming.
NOTE
The CGW-T4 cellular channel will not answer incoming calls when programming mode is active.
Exit from the programming mode by *900 (Recommended) or hanging up the telephone.
If you do not enter digits for 45 seconds, the channel 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.

6.1 DTMF Programming Commands
Operation Command Default
Enter the Programming mode *900 + XXXX
where:
XXXX = Password (1234 default)
Exit the Programming mode *900
Maximum number of digits to be dialed by the CGW-T4 Note: Less than XX digits – there will be a time-out of 3 seconds (default), before the dialing starts. Exactly XX digits – the number will be dialed directly. More than XX digits – the number will be cut off after XX has been reached.
Time-out value in seconds. This defines how much time the unit waits before dialing the number shorter than the maximum number of digits defined with *300).
*300 + XX where: XX = 05-20 (digits)
*310 + X where: X = 2 - 9
1234
11 (Tip: set the default to country’s max. telephone number length.)
3 (sec.)
Reverse Polarity
The unit may be set up to send a “reverse polarity” command to the PBX, in case a “call answer” is detected. This parameter is useful if call accounting software is active.
Output Volume Control *330 + X
CGW-T4 Telephone Number Enter the SIM telephone number
to be displayed on the LCD during power-up of the unit.
(GSM only)
*320 + X where: X = 0 – 2 0 = No reverse polarity 1 = Reverse polarity only on Outgoing calls 2 = Reverse polarity for Incoming and Outgoing Calls
where: X = 0 – 7 (CDMA)
X = 0 – 9 (GSM)

(GSM only)
Conversation Time-Out
The telephone conversation will be automatically terminated after this time-out.
End Dialing Digit
Define "#" as the digit that indicates the end of a dialed number, causing the unit to immediately start dialing.
*350 + X, where: X = 1 enabled; X = 0 disabled
*360

(GSM only)
Pulse drop (Loop Disconnect)
Activate the pulse drop feature by defining time for loop disconnect for conversation end state signaling to PBX.
Call barring (number of restricted numbers reduced to 8).
*380 + XX where: XX = time in tenth of seconds. For example:
X = 10=1000 milliseconds = 1 second
X = 01 = 100 milliseconds
Legal values: 00-99
Note: If this feature is activated together with reverse polarity (*320) 'Pulse drop' occurs after polarity is reversed.
