CGW-I Cellular Gateway BRI-GSM : Installation and Operation Manual ii
1. Overview
Your new CGW-I cellular gateway connects your PBX (Private Branch
eXchange) directly to a GSM cellular network, using the ISDN BRI interface.
By routing your outgoing calls made to cellular numbers through your new
device, you bypass the landline carrier and eliminate excessive
interconnection fees, thus cutting your telephone costs significantly.
The CGW-I offers 2 voice connections and your choice of integrated dualband GSM modules (900/1800, 850/1900 MHz), enabling you to work with
2 different GSM network operators simultaneously.
Also included with your new device is the CGW-I Manager, the BRI-GSM
Utility Program, needed to configure your device with a rich variety of
features that you will learn about as you read through this manual.
1.1. About this Manual
This manual describes the installation, setup and operation of your new
Cellular GateWay for ISDN (BRI interface), which we will now simply refer to
as the CGW-I throughout this manual. It is intended for System Installers and
Administrators and should be read before the installation, setup and
programming of your device.

2.3. Pre-Installation
Your CGW-I device 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.
Note:
Before installing the SIM card, we recommend disabling all Call Forwarding modes (in the
events of busy, absence, unavailability, etc.) and Call Waiting from the GSM operator.
The PIN code requests on the SIM must be disabled to complete the initial
installation. You can disable the SIM with any GSM mobile phone.
If you enable the PIN after installation using your mobile phone, you must
enter the PIN in the Channel Settings screen (see page 33) before you can
make changes to the CGW-I and so that it will work after power up and
reset. If you enter an incorrect PIN three times in the Channel Settings screen
and are locked out by the SIM, you must enter the PUK code to unlock the
SIM.
Note:
To get the PUK code number, you must call your network operator (i.e., local GSM
Service Center). Once you enter the PUK code and unlock the SIM, you must still enter
the correct PIN to use the CGW-I.

2.4. PBX Trunk Configurations
The following configurations describe different PBX Trunk configurations
with TE and NT interfaces which you use to connect the PBX to the PSTN and
CGW. The TE interface always receives an independent time clock from the
NT source. A PBX that receives two different source clocks may experience
communication errors, such as the inability to properly disconnect a
completed call.
The following diagrams offer different solutions to handle a double source
clock situation. In each configuration, a person attached to the PBX dials a
number which is first routed to the PBX LCR (Least Cost Route) to verify the
calling prefix, then routed to the correct interface:
• If the prefix is landline, it creates a connection for the call to leave
via the PSTN interface
• If the prefix is cellular, it routes the call to the CGW-I interface and
the CGW-I connects the call through a cellular network operator.

CGW-I Cellular Gateway BRI-GSM : Installation and Operation Manual 7
This diagram describes an NT1/CGW-I configuration option which can be
used when the PBX requires a single source clock and an NT1 device
connects the PSTN to the PBX. By connecting to the NT interface of the NT1
which sends the source clock to the PBX to the Synch-In interface of the
CGW, the CGW-I is able to ensure synchronization of the NT source clock it
sends to the PBX by using the source clock that the PSTN sends to the PBX.

This diagram describes an ISDN Extension/CGW-I configuration option which
can be used when the PBX requires a single source clock and the PBX has an
NT interface to an extension telephone or terminal adaptor. It is common
when the communication between the PSTN and PBX is over a direct PRI
connection and there is no NT1 for synchronization. By connecting from the
ISDN cable leaving the NT interface of the PBX to the Synch-In interface of
the CGW, the CGW-I is able to ensure synchronization of the NT source
clock since it sends back the same source clock it received from the PBX.
Utilizing the existing cable also lets you avoid using additional ISDN BRI
resources (i.e., B1 or B2).

CGW-I Cellular Gateway BRI-GSM : Installation and Operation Manual 8
This diagram describes a configuration where the PBX uses a proprietary
interface connection to the different telephone extensions. Therefore, the
PBX requires a special NT card to create an additional NT interface leaving
the PBX which will provide the source clock. By connecting the new PBX NT
interface to the Synch-In interface of the CGW, the CGW-I is able to ensure
synchronization of the source clock it sends back to the PBX.

CGW-I Cellular Gateway BRI-GSM : Installation and Operation Manual 9
This diagram describes a simple PBX NT/CGW-I configuration where the PBX
provides a direct NT interface to the TE interface of CGW. Synchronization is
automatically ensured in this configuration since the single connection to the
CGW-I includes the source clock sent by the PBX.
External Synchronization Feature
If you set up your CGW-I with a configuration that uses the Synch-In
interface to ensure synchronization, you must enable the External
Synchronization feature in the ISDN Settings window. When this feature is
enabled, the CGW-I time clock becomes a “slave” to the external time clock
since it takes the clock it receives from the NT source. When this feature is
disabled, the CGW-I becomes the “Master” of the time clock it sends to the
PBX. You should also disable External Synchronization when the CGW-I
connects to a TE interface. To learn how to set enable the External
Synchronization feature, see page 27.
2.5. Installation
Setting up your CGW-I requires at least one SIM card from the local GSM
network provider and a few simple connections between the CGW-I box and
the following:
• RS-232 (Setup)
• Antenna
• Communication line
• Synch-In line (Optional)
• ISDN trunk interface of your PBX fxo
• Power supply.
The following sections describe how to make all these connections.
Hanging Up the CGW-I
You can hang the CGW-I on the specially designed mounting plate or
directly on the wall.
To hang the CGW-I directly on the wall, first drill holes according to the
enclosed template, then drill in screws and hang the device from them.

SIM Card Insertion
CAUTION:
To avoid damage to your CGW-I device, you should disconnect the 9V adapter from the
electric power-outlet when inserting or removing the SIM card.
The figure above can be used as guideline for the following steps:
1. Hold the device in your hands with the display pointed to your
right and the SIM insertion slot at the bottom of the unit towards
you.
2. Use a pointed pen or screwdriver to push the round yellow SIM
release lever. The SIM card tray should move out towards you.
CGW-I Cellular Gateway BRI-GSM : Installation and Operation Manual 11
3. Take out the tray. You will see that the SIM card will fit in the tray
only one way.
4. Carefully place the tray with the SIM card back into the slot and
slide it in with the SIM card contacts facing up.
Connecting to the CGW-I

Screw in the antenna cable(s) to the antenna to the Ant. 1 or Ant. 2
connector.

Note:
If you are only using one SIM card, make sure that the channel number is the same as
the antenna connector you are using (i.e., SIM1 uses Ant.1).
Connecting the Communication Lines
The following diagrams show the different cables that connect to your
device.
