Introduction - ITS Telecom CelluLine CGW-TS Installation And Programming Manual

1 Introduction

Your new ITS CelluLine CGW-TS is a cellular gateway that
connects your PBX (Private Branch eXchange) directly to a
GSM network, bypassing the landline carrier. By routing your
outgoing calls made to cellular numbers through your new
CGW-TS, you will be able to eliminate excessive
interconnection fees charged by the landline carrier, thus
cutting your telephone costs significantly.
Setting up the CGW-TS requires a simple connection from the
analog trunk interface of your PBX-fxo to your new CGW-TS
unit. Once connected, you insert the SIM card for your GSM
cellular provider's network into the unit, attach the antenna
and plug in the power. You are now ready to make your first
call from your phone extension directly through your GSM
network. A detailed explanation of how to set up the CGW-TS
can be found on page 5.
The CGW-TS has 6 LEDs that show the received signal level
and other useful call progress information. A detailed
explanation of the LED status indicators can be found on
page 9.
You can program additional CGW-TS parameters, such as
Audio volume control, Conversion Time-out and Restricted
Digits, via DTMF commands. A detailed explanation of these
parameters and others can be found on page 15.
