FIG. 1  

CSG SIP Communications Gateway (displaying CSG-544)

Overview

The CSG SIP Communications Gateway (FIG. 1) is a stand alone Private Branch 
Exchange (PBX) which runs a version of Asterisk. The CSG can function not 
only as a PBX, but also as VoIP ATA, or VoIP gateway. It has eight analog ports 
that can be configured (via modules) as Foreign Exchange Office (FXO) or 
Foreign Exchange Station (FXS) ports.

The CSG enables you to transform an intercom-enabled Modero Touch Panel 
into a full-featured IP phone. With the CSG and an intercom-enabled Modero 
Touch Panel you can make and receive local, long distance, and international 
phone calls, and have access to phone features like call waiting, caller ID, call 
forwarding, call queuing, and voice mail. The CSG supports AMX Session 
Initiated Protocol (SIP)-enabled touch panels, such as the MVP-8400i, 
NXD-1000Vi, and NXD-700Vi, as well as 3rd party IP phones.

Specifications  

Installing the Hardware

CAUTION!

To reduce the risk of fire, use only No. 26 AWG or larger 
telecommunication wiring for network connections.

1.

Connect an Ethernet cable to the Network port.

2.

Connect the provided power supply to the unit’s DC connector. The unit 
immediately receives power once you connect a power source to it.

3.

When the unit completes the boot process, the left-most eight LEDs 
indicate how the analog ports are configured. A red light indicates the port 
is FXO, and a green light indicates the port is FXS. If the light for a port is 
off, the port is not installed.

Note:

 

The analog port configuration is selected when you purchase your CSG 

unit.

4.

Connect telephones to the analog ports that are configured as FXS ports 
and connect phone lines to the analog ports that are configured as FXO 
ports. If you are using the CSG-500, you can skip this step.

WARNING!

If you are using the CSG-544, do NOT connect analog ports 1-4 to 
a phone line. Since both the FXS port and the phone line supply 
power, the hardware could sustain damage. This damage is not 
covered under the AMX standard warranty.

Instructions for Wall Mounting

1.

Select the area to mount the CSG unit. The unit should be mounted at or 
below eye level to properly view the LEDs.

2.

Line up one of the surface mounting brackets with the two holes on one 
side of the CSG. Install two #4-40 X .250 PPH screws into the holes in the 
bracket to secure the bracket to the CSG.

3.

Repeat step 2 to attach the second bracket to the other side of the unit.

4.

Affix one screw to the wall.

 

Leave approximately 1/4-inch of the screw 

protruding from the wall to allow  the head of the screw to slide into the 
settings on the mounting bracket, mounting the unit to the wall.

5.

Repeat step 4 to attach the second bracket to the wall.

Understanding the LEDs

There are 14 LEDs on the front panel of the CSG. The eight LEDs corresponding 
to the analog ports on the rear panel indicate the type of interface installed. The 
following table explains the definition of each LED and its color representation:
