CGW-T4 Installation and Programming Manual

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.
