The CSG SIP Communications Gateway is a stand alone Private Branch Exchange (PBX). It is suitable
for the desktop, or mounting in a typical network closet or restricted access location. The CSG is ideal
for small office environments or as an extension to a central CSG PBX.
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 comes in three different models: the CSG-500, CSG-544, and CSG-580. The CSG-500
supports up to 50 users, but offers no analog lines. In addition to supporting up to 50 users, you can
integrate the CSG-544 and CSG-580 to outside PSTN or POTS networks. The CSG-544 allows for up to
four phones and four PSTN lines. The CSG-580 allows for up to eight PSTN lines. The CSG supports
AMX Session Initiated Protocol (SIP)-enabled touch panels—such as the MVP-8400i, MVP-5200i,
NXD-1000Vi, NXD-700Vi, and NXD-500i—and the MET-ECOM Metreau Entry Communcator, as
well as 3rd party IP phones.
In a typical network, the CSG acts as proxy server, registrar, and gateway. A SIP-enabled touch panel
acts as a user agent, which allows the touch panel to act as an IP phone. FIG. 1 displays a high-level
diagram of the recommended network infrastructure for using the CSG.
The CSG interface enables you to create a PBX solution that rivals the features and functionality of
traditional telephony switches. Current PBX solutions are expensive and proprietary. Using the CSG,
you can replace an existing small business PBX. Since it runs on Linux, it inherits all of the power and
stability of that operating system. The CSG works with most standards-based IP telephone handsets and
software. The CSG also supports analog phones and ADSI-screen phones.
When you unpack your unit, carefully inspect it for any damage that may have occurred in shipment. If
damage is suspected, file a claim with the carrier and contact your reseller from which the unit was
purchased or AMX Technical Support.
Keep the original shipping container to use for future shipment or proof of damage during shipment.
Only qualified service personnel should install the unit. Users should not attempt to
perform this function themselves.

Installation
Identifying Communication Ports
The CSG unit consists of up to eight RJ11 analog ports which can be configured as either FXO or FXS
ports, depending on the type of modules installed in the CSG model. These ports provide 16ms of analog
port echo cancellation. The unit is rated for a total of 8 REN across all FXS ports. Each individual port is
rated for up to 3 REN @ 1500ft (450m).
Four 10/100BaseT LAN ports and one 10/100BaseT WAN port provide the functionality to connect to
the local network as well as allowing the CSG to act as a router. All the Ethernet ports support
auto-MDI/MDX.
An RS-232 console port is also available for additional configuring of the pre-loaded CSG software via
direct physical access. The preferred method for configuring the unit is by using the web based interface.
You can also configure it remotely using SSH. The CSG is shipped fully configured, but it may be
altered for specific applications.
FIG. 2 displays the ports and their corresponding LEDs.
The example shown is configured with four FXO and four FXS ports, model CSG-544.
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 definition of each LED and its color
representation is explained below.

Using the Configuration Reset Switch
The Configuration Reset (CFG RST) switch (rear panel - see FIG. 3) resets the current configuration to
the factory defaults when pressed. The switch must be continuously pressed during the boot process.
This will force the unit to delete all configuration data.
1. Connect an Ethernet cable connected to your network to the Network port on the back of the CSG.
2. Connect an Ethernet cable an IP Phone port. This will be used during the initial configuration of the
CSG.
3. Connect the provided power supply to the unit’s DC connector. The unit immediately receives
power once you connect a power source to it.
4. 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.
The analog port configuration is selected when purchasing your CSG unit.
5. 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.
If you are using the CSG-544, do NOT connect analog ports 1-4 to a phone line.
Since both the FXS ports and the phone lines supply power, the hardware could
sustain damage. This damage is not covered under the AMX standard warranty.
This unit must be connected to the Telecommunications Network in your country
using an approved line cord, e.g.: for Australia use only line cords complying with
ACA Technical Standard TS008.
This unit must be connected only to the appropriate Telecommunications Network
port (as approved for use in your specific country).
To reduce the risk of fire, use only No. 26 AWG or larger telecommunication wiring for
network connections.
Select the area to mount the CSG unit (refer to FIG. 4). The unit should be mounted at or below eye
1.
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.
Instructions for Wall Mounting Using DIN Rail Mounting Brackets
The AC-DIN-CS3 DIN Rail Mounting Brackets (FG532-06) allow you to install the CSG on a standard
DIN rail (or “top-hat” rail). The DIN Rail Mounting Bracket comes in a kit that includes everything you
need to mount a single device on a standard (35 MM. wide) metal DIN rail. Follow these steps to mount
the CSG using the DIN rail mounting brackets:
1. Use the four supplied flat-head screws to secure the DIN mounting clips to the bracket.
2. Use the two supplied pan-head screws to secure the bracket/mounting clip assembly to the CSG.
Use the mounting holes on either side panel of the enclosure to mount the bracket/mounting clip
assembly.
There are indicators on both the bracket and the mounting clips to show which end is the “top” to ensure
correct mounting orientation (see FIG. 5).
The bracket has a notched side to indicate the top of the piece. The DIN mounting
clips also have two holes drilled in the top portion of the clips that indicate the top of
the clip.

This chapter provides information on how to initially set up your telephone system via the CSG Interface. The
CSG Interface gives you the ability to set up your telephone system without the need to use command line
configuration. After connecting to the CSG, the primary menu is displayed, giving you the ability to configure
your system, as well as add features to your call system as your needs change.
Logging On to the CSG
Your CSG should already be connected to an internet or network connection, as described in the Installing the
Hardware section on page 9. In the address field of a CSG supported web browser, enter the IP address
assigned to your CSG. The default LAN IP address is 192.168.69.1.
Telephone System Configuration
FIG. 9 CSG Interface Login
To log on to the system enter the following credentials:
Username: admin
Password: <password>
The first time you log on you will be prompted to change your password from the default. You should have
already chosen a new password during the installation process. Once the log on process is complete the CSG
Interface home page will be displayed.
Subsequent Logins to the CSG
The method described above will work to log onto the configuration tool of the CSG. In addition, you
can log onto the CSG using the CSG's Network port once it has been enabled. In this case, open a web
browser on a computer which is located on the same network as the CSG. In the address field of the web
browser, enter the IP address of the CSG as defined during the initial installation.
You can also log on to the CSG by using a zero-configuration networking client that allows you to determine
the unit’s IP address, such as Bonjour or a similar zero-configuration client. Zero-configuration (or Zeroconf,
also known as "Bonjour") technology provides a general method to discover services on a local area network.
In essence, it allows you to set up a network without any configuration, as described below.
You may need a zero-configuration client to determine the IP address of the CSG. There are many
zero-configuration clients available. However, for the purposes of this document, we will refer to Bonjour for
Windows. It is free, and widely available for download. If you don’t already have it installed on your PC,
download and install Bonjour for Windows before you begin.
Perform these steps to log on to the CSG through Bonjour for Windows:
1. With Bonjour for Windows running on a PC that has access to the LAN on which the CSG resides,
connect the CSG to the network (see the Installing the Hardware section on page 9.)
2. In Bonjour, you will see the unit join the network at power up (FIG. 10). Double-click the CSG link
to access the CSG Login page (FIG. 9).
FIG. 10 Bonjour for Windows - screen
3. To log on to the system, enter the following user name and password:
Username: admin
Password: 1988
As shown in FIG. 10, Bonjour for Windows operates as a plug-in to Internet Explorer
(version 7 shown), and is displayed in the IE Explorer Bar. If you have installed
Bonjour for Windows, but don’t see the Bonjour toolbar icon, you may need to
"unlock" and expand the toolbars to see it.
The CSG Interface gives you the ability to configure the basic hardware and dial plan elements you need when
initially setting up your system. You must create trunks, system users, conferencing, voice mail, etc. After
logging into the CSG Interface, you’re presented with a variety of options on the left side of the page.
FIG. 11 System Status Page
The CSG Interface supports the following browsers:
Firefox 1.5 through 3.0
IE 7
Safari 3.x
Opera 9.x
Every page of the CSG Interface has two columns. The left column identifies all the elements for which you
can program the CSG. The elements listed begin with System Status, which is the first page you see upon
logon, and proceed down to Options. Clicking any of the tabs on the left of the page opens the corresponding
page in the right column. Many pages have additional information. Click on the information symbol, a blue “i”
enclosed in a circle, to get more information about a field or page.
The System Status page is the default page. This page shows you the current version of firmware you are
using, the status of any trunk lines you have configured, the realtime status and additional details of all user
extensions, including the new and old voicemail message count for each user extension (e.g. Messages: new/
old), and the realtime status of all agents, conference rooms, and parked calls. You can click on most extension
definitions to get more information. In addition, the System Status page gives you the ability to log in, log out,
pause, and unpause an agent that is associated with one or more call queues.
A user extension will have the status of “Unavailable” when the VoIP account
associated with it is not registered to the CSG. The status will not change to
“Unavailable” when a user extension has both an analog port and a VoIP account
associated with it.
In the upper right corner of each page you will see the Apply Changes and Logout buttons. Click Apply
Changes to save and activate any changes you have made on a page so that you can utilize the changes. Click
Logout on any page to exit the CSG Interface.
Analog Hardware Configuration
You must configure your analog hardware according to the needs of your system as part of your initial CSG
configuration. The Configure Hardware page gives you the ability to configure both your FXS and FXO
ports, as well as your Tone Region, operation mode, message waiting indicator mode (MWI), etc. The number
of FXS and FXO ports available for configuration will depend on the CSG model you purchased. Click the
Configure Hardware tab to configure your analog hardware.
The Configure Hardware tab will not be available if you ordered a VoIP only model.
FIG. 12 displays the Configure Hardware page.
FIG. 12 Configure Hardware
FXS and FXO ports provide the ability to receive and send calls through the traditional telephone network, or
POTS (Plain Old Telephone System). FXS modules provide both dial tone and ringing voltage to an analog
phone. FXO modules accept dial tone and provide an interface to the traditional phone lines. You plug a
telephone line into an FXO port, and an analog telphone into an FXS port.
On this page you can specify the signalling type for your FXS and FXO ports. You have two choices; either
Kewl Start or Loop Start. The Loop Start method uses a short to request a dial tone. All North American home
phone lines use loop start signalling. Kewl Start is the same as Loop Start, but is better able to detect
disconnects. Select either Kewl Start or Loop Start for each FXS and FXO module. Kewl Start is the default
and is preferred for analog circuits in the CSG.
Ground Start signalling is not supported.
You also need to select a tone region, which defines the set of tones (dial tones, ringing tone, busy tone, etc)
used in your region. Select your country, or the nearest neighboring country, from the Tone Region drop-down
list. The default setting is North America (United States/Canada).
