CGW-T/TS/D Installation and Programming Manual 1
1 Introduction
Your new CGW-T is an analog GSM/CDMA Cellular Gateway (CGW-TS/D – 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 an 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/D 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/D can immediately start saving money for you. The unit
has an LCD display, which shows the GSM/CDMA operator’s name (CGW-T/D only), the
signal strength and other useful call progress information.
A number of additional parameters for the CGW-T/TS/D, such as Output Audio Volume level
setting, Conversation time-out and Restricted Digits, can be programmed via DTMF.
The CGW-T, CGW-TS and CGW-D units are displayed in Figure 1.

CGW-T/TS/D Installation and Programming Manual 3
Calls that are intended to be routed to the cellular network by the CGW-D, will be routed to
the PSTN network instead in the following cases:
 A SIM card is not installed at all or not installed properly.
 Cellular reception level is too low.
 CGW-D device is in Registration mode.
 CGW-D is not powered by the power supply.

NOTE
When the PSTN interface is plugged out, all calls shall be executed via a cellular
network, and a corresponding message will appear on the LCD display.
The Toll Restriction feature is implemented as follows:
 CGW-T/TS devices use a black list of 10 restricted prefixes, which cannot be dialed.
 CGW-D device uses a white list of 20 permitted prefixes, which are the only prefixes
that can be dialed via a cellular network.
