Chapter 1- Introducing the QSX System
The Polycom QSX™ system allows users to instantly share anything on their computer
screens with remote locations via the Web or with other QSX or VSX locations. Users
don’t need to learn new applications, upload documents, pay monthly service fees, or pre-
schedule meetings. It’s an easy and secure way to share content with remote sites. QSX
systems have the following features and benefits:
Easy one-time setup – Simply plug in your IP connection, power and VGA cables. Easy
Web interface for additional optional configuration.
Easy to use – Instant content sharing without wasting time on downloading applications,
uploading documents, advance scheduling or user training.
Open architecture – Works with any content, any phone systems and any type of
computer or VGA input source- even those belonging to presenters who can’t get access
to the network.
Multi-point capability – Each QSX session shares content directly with up to ten sites
per QSX via a standard web browser. Scale to even more sites by connecting directly
with up to four other QSX units or leverage a Polycom MGC conference bridge for large
scale meetings.
Cost effective – The QSX provides unlimited content sharing. It pays for itself quickly
because there are no monthly charges or per-minute fees.
Content security – Keep complete control over your document. AES (Advanced
Encryption Standard) media encryption on QSX to QSX calls, secure login for Web
browser access, and the ability to share information without releasing control of it ensure
your content is protected.
Simply connect your computer to the QSX VGA cable and share content, including
business applications, proprietary software, the Internet, images, and software demos –
all at the touch of a button. The QSX user interface provides convenient information
screen (Info Screen) overlays that show presenter/viewer locations and connection
information, as well as the Web address and login information for remote participants.
Usage Overview
QSX systems allow content sharing with other QSX systems and with remote sites via the
Web. Alternately, QSX systems allow content sharing with Polycom videoconferencing
equipment including the VSX 8000, VSX 7000e or the VSX 7000s with Visual Concert.
Finally, the QSX is interoperable with the Polycom MGC bridge, allowing you to scale
the number of web, QSX and video participants in a meeting based on the number of
ports and bandwidth available on the MGC itself.

Chapter 2- QSX Overview
QSX Equipment Overview
There are two basic versions of the QSX. The QSX 400 is designed to work in
environments without a conference phone or with Polycom’s analog SoundStation,
SoundStation2, SoundStation Premier or SoundStation2W conference phones. The QSX
300 is specifically designed to work with the Polycom VTX 1000 conference phone. The
QSX 300 does not require a content controller because that functionality has been
designed into the VTX 1000 phone and can be accessed through the menus on the phone
itself.
QSX 400 Components
When sharing content between two QSX units, you will need one Polycom conference
phone connected to each QSX for the session. If only sharing content with web viewers,
it is not required to connect a phone to the QSX.

Chapter 3- Typical QSX Usage Scenarios & How QSX
Works
QSX in Stand Alone Mode
One of the main advantages of the QSX is the ability for people to log into a meeting via
the web from a remote location.
In order to set up and initiate a call with a web viewer, the QSX user should follow these
steps:
1. Make sure the QSX system is properly connected. You can check your settings
by referring to the QSX Quick Start Guide that came with the product.
2. Connect your computer to the QSX and make sure that the QSX is in Preview
state. If you’re using a Content Controller, the light should be yellow. If your
16
Download from Www.Somanuals.com. All Manuals Search And Download.
QSX is connected through a VTX 1000, you should see “Preview” displayed in
the telephone’s display window.
3. Set up the presentation on your computer and initiate a call with the web viewing
party. Note that even though the QSX is not required to be connected to a
SoundStation phone in the Stand Alone Mode, it is assumed that you will still
have an audio connection with other meeting participants.
4. Press the Info button on the Content Controller
or VTX 1000 keypad
to
obtain the IP Address and Meeting Password for the meeting. Both of these will
be displayed on the Info Screen as shown below.
5. Direct the web viewer to connect to the internet, launch a web browser and enter
the IP Address in the browser window.
6. The web viewer will receive a pop-up asking him for his user name and password.
He should enter his name in the User Name field and the Meeting Password that
you gave him in the Password field.
7. He will get a message that content is being loaded. You will see the QSX
automatically move from Preview to Send. After a short delay, the web viewer
will be able to see the content you’re displaying on the computer in your location.
*- Note that if you are going to share content with web viewers outside your organization,
you will need both an internal IP address and an external IP address. You should obtain
one from your network administrator. When you communicate an IP address to
participants outside your organization, you will give them the external IP address which
can be obtained by hitting the Info button on either the Content Controller of the QSX
400 or the soft key option on the VTX 1000 if you are using a QSX 300 with VTX 1000
conference phone.
Note: The web browser must be Java-enabled in order to receive content from a QSX.
Note: By default, a new Meeting Password will be generated after a meeting has ended
and there have been 60 minutes of inactivity. Alternately, you can reset the password by
holding the Info button for at least 4 seconds as long as the QSX is in Idle or Preview
17

mode (i.e.- not sending content to web viewers). There are other password options that
you can access from the QSX’s Web Administrator page. These are described on Page
30.
Note: Web viewer sites do not necessarily need to participate in a phone call with the
presenter in order to see content.
Disconnecting Web Viewers
When the QSX ends a presentation, you can disconnect the web viewers by ensuring the
QSX is in Idle or Preview mode, then holding the Info button down for at least 4 seconds.
If the QSX user re-initiates the presentation but hasn’t changed the password, the web
viewers will need to refresh their browser and log in again.
Note: A maximum of 10 web viewers can connect to each QSX during a meeting.
Note: If the QSX has a SoundStation or VTX 1000 phone attached, this configuration
will override the stand alone operation. Placing the SoundStation or VTX 1000 on-hook
(i.e. - disconnecting the call) will drop all web viewer connections as well as H.323 calls
and web viewer connections.
QSX Connecting to Other QSX Systems
In calls between QSX systems, the systems automatically identify each other over the
phone line using standards-based Low Profile Signaling Protocol (LPSP). The signal is
embedded in the standard audio frequency band. When an audio call is placed, the QSX
units connect to each phone and begin to communicate. After the QSX systems identify
each other, typically within 15-30 seconds, they automatically establish a H.323 content
sharing channel over the LAN. One QSX system becomes the initial meeting controller
and its IP address becomes the Meeting Web Address. At this point, web viewers can
also join the meeting and receive content from the presenting QSX.
18
Download from Www.Somanuals.com. All Manuals Search And Download.
Note: A maximum of 5 QSX units can connect directly to one another for a meeting.
For higher scaling, refer to Interoperability with Polycom MGC below.
Note: In a QSX-to-QSX meeting, web viewers are still able to login and view content.
Note: There are several advantages to a QSX-to-QSX meeting. First, the direct
connection eliminates the need to communicate IP addresses and passwords to other
meeting participants. Second, all content between QSX units is encoded in 128-bit AES
encryption. Third, a QSX-to-QSX connection provides higher frame-per-second
transmission of content. Fourth, the H.323 connection between QSX units minimizes
delays in content transmission. Finally, in a meeting with multiple QSXs, it is possible to
change which room is sending content. If a different QSX system starts sending content
during the meeting, content from the new presenting unit is automatically directed to web
viewers through the QSX they originally connected to. Web viewer sites can continue to
view meeting content until the QSX system hangs up or stops sending content.
QSX Connected to Polycom Video Systems
In videoconferencing environments, you can enhance the capabilities of People+Content
by adding a QSX. There are two ways to add a QSX to a video environment.
First, you directly connect the QSX to a VSX 8000, a VSX 7000e or a VSX 7000s
(through Visual Concert) using VGA cables. In doing so, you can share content with
people participating in the meeting who do not have video capability (e.g.- salesperson
calling into the audio bridge from a remote location such as a hotel room). An example of
this type of scenario is shown below.

In order to utilize the QSX as a web-conferencing device and allow people without video
capability to share content in a video-enabled meeting, follow these steps:
1. Ensure the video system is properly connected and configured. For more
information about Polycom’s video systems, refer to the Administrator’s Guide
for the respective product.
2. Connect the power and LAN connections of the QSX as described in Chapter 3 of
this guide.
3. Connect the Content Controller to the VGA-In port of the QSX as described in
Chapter 3 of this guide.
4. Connect a standard VGA cable from the VGA-Out port of the QSX to the VGA-
In port of the Visual Content (for VSX 7000s) unit or directly to the VGA-In port
of the VSX 7000e or VSX 8000 unit.
5. Connect your laptop or computer to the Content Controller. By default, the
Content Controller will be in auto-preview mode, so content will be sent to the
Visual Concert or VSX unit.
6. To send content to far-end participants via the Visual Concert unit, press the send
button on the unit itself. To send content to far-end participants via a VSX 7000e
or VSX 8000, press the Graphics button on the unit’s remote control.
7. To enable web viewers to access the content, press the Info button on the Content
Controller. Provide the web viewers with the IP address and password of the
QSX unit. They can then open a browser, log into the IP address and enter their
name and the password to view the content.
Note: In this mode, People+Content operations will work as normal.
The second way to connect a QSX in a video environment is to use the video system’s
remote control to dial the IP address of the QSX. You will be prompted for the QSX
unit’s password. Once you’ve successfully entered the password, the video system will
be connected via a H.323 connection. Content can be sent from the QSX to the video
unit and from the video unit to the participants who have logged onto the QSX via the
Web.

QSX Usage with Polycom MGC
The QSX system can be connected to an MGC bridge to increase the scalability of
content sharing beyond 5 QSX units. It does so by leveraging the capabilities of the
MGC.
To use a QSX with an MGC bridge, follow these steps:
1. Ensure the MGC is properly connected and configured. For more information
about Polycom’s MGC systems, refer to the Administrator’s Guide for the
respective product.
2. Connect the power and LAN connections of the QSX as described in Chapter 3 of
this guide.
3. Enable MGC Dial Out by going to the Web Admin Page, Admin Settings
>Video/IP Network > H.323 Settings > Enable MGC Dial Out Conference
Calls.
4. For MGC configuration, consult the Administrator’s Guide for that product.
This capability enables the QSX to answer a call from an MGC in one of two scenarios.
MGC Dial-Out. There are two ways that the MGC can connect to the QSX. First, it can
dial out to the QSX directly by dialing its IP address. Second, if both the MGC and QSX
are registered to a gatekeeper, the MGC can dial the E164 extension of the QSX. In
either situation, once the MGC has made the connection, the QSX can send and receive
content. The link to the QSX has to be disconnected by the MGC. There is no way to
disconnect from the QSX side.
Dial-in with a SoundStation VTX 1000. A user can utilize a SoundStation VTX 1000
phone attached to the QSX can dial into the MGC using the Manual IP Dialing method
described on Page 12.
21
Download from Www.Somanuals.com. All Manuals Search And Download.
After the MGC call has connected to the QSX, the QSX unit will not connect to any other
QSX or video units. Other non-QSX units must access the content via the MGC bridge.
If the QSX is already in a call with another unit (i.e. – QSX or video unit) and the MGC
calls it, it will reject the MGC call.
Note: It is strongly recommended that you only use the MGC’s dial-out mode for
connecting to the QSX. Doing so avoids establishing a QSX-to-QSX connection before a
connection between the QSX and MGC is established. If this happens, the MGC dial
attempt will be rejected.
Note: When participating in an MGC-hosted meeting with a VTX 1000 conference
phone, you will only see two parties on the QSX unit’s Info Screen—you and the MGC.
If you see more meeting participants, you should hang up the call and use the VTX 1000
to manually dial into the MGC unit again.
Chapter 4- Setting Up the QSX System
Connect the QSX System
Connect the QSX System, by following these steps (for more information and a graphical
depiction of these steps, consult your QSX Quick Start Guide.
1. Connect the following cables:
• LAN Cable. Connect the LAN cable from the back of the QSX unit to an
active LAN port in the area where the QSX will reside.
• Power Cable. Connect the Power Cable from the back of the QSX unit to
an available power outlet.
• VGA Cables.
For the QSX 400, connect the Content Controller to the VGA-In port
on the back of the QSX unit, and then connect the VGA cable to
the Content Controller itself.
For the QSX 300, connect the VGA Cable directly into VGA-In port
on the back of the QSX unit.
If you plan to display content on a projector or second computer monitor in the
area where the QSX will reside, you will need an additional VGA cable that
connects from the VGA-Out port
on the back of the QSX unit to the
display equipment. Note that this VGA Cable is not included with the QSX
system.
Note: The only way to display the Info screen is to use a second display (e.g.-
second monitor, projector, etc.)
22

2. Step 1 is all that is required to set up your QSX system. If you plan to use it with
a Polycom conference phone, please connect the following cables as well:
• 8-wire cable for phone console. Connect the 8-wire cable from the back
of the QSX unit to the Polycom conference phone.
• Conference Link Cable. For use with a Polycom VTX 1000 conference
phone only. Connect the cable from the phone to the back of the QSX
unit.
Note: You will also need a POTS module cable that connects to the SoundStation
console. This cable ships with the SoundStation phones.
Set an IP Address
By default, the QSX system obtains its IP address automatically. You need the IP
address of the QSX system in order to access its Admin Web interface.
If your QSX system obtains its IP address automatically, it is displayed as My IP on the
Info screen when you press the Info button on the content controller, or the INFO soft
key on the SoundStation VTX 1000 conference phone.
If your location does not allow dynamic IP address assignment, contact your IP network
service provider or system administrator to obtain an IP address and system name. You
must manually assign the static IP address to the QSX system before you use it.
Note: The default mode for IP Address is dynamic. This means that the QSX system
will automatically request an IP address from a DHCP server if there is one on your
network.
Accessing the QSX Web Admin Page
To see if your QSX system obtained its IP address automatically, follow these steps:
1. Once QSX is connected, hit the Info button on Content Controller.
2. If screen shows an IP address in the “My IP” field, go to the next step. You may
need to wait a few minutes for the DHCP server to assign an IP address to the

Admin Settings
Admin Settings are divided into five groups—General Settings, Video Network/IP
Network, Global Services, LAN Properties and Graphics Display.
General Settings
System Settings
System Settings allow you to give a name to your QSX (e.g.- You may want to name it
“Pebble Beach Conference Room” if that’s where the unit will be located). You can also
set Low Profile Signaling Protocols (LPSP) based on your expected usage of the QSX
system. For more details on each of these settings, consult the table below.
To configure system settings:
1. Log on to the QSX Admin Web as described on Page 23.
2. Go to Admin Settings > General Settings > System Settings.
3. Configure these settings:
Setting
System Name
Description
Specifies the system name in this field. This name is displayed to other
meeting participants.
(default: serial number)
LPSP Gain
Specifies the gain for the Low Profile Signaling Protocol (LPSP). Increase
the gain to 300 or 400 if you expect the QSX system to handle international
calls.
(default: 200)
If the QSX is to be used in a Stand Alone Mode, configure the LPSP Gain
to zero.
LPSP Delay
Specifies the delay in seconds for LPSP activation. Increase the delay if
conference bridges that require pass codes are being used. Extra delay
might be necessary to prevent the QSX system from disrupting DTMF
transmission of the audio conference pass codes.
(default: 15)
Note: Low Profile Signaling Protocol (LPSP) is the method that the QSX systems use to
establish a connection with one another. In doing so, they transmit and decode site
identification. The QSX units use a small fraction of the standard 3.5 Hz bandwidth
allocation of a typical POTS call for the LPSP communication.
Security
The QSX system allows you to share content with other meeting participants in a secure
manner. By not transferring files, you ensure that they won’t be accessed by
unauthorized viewers or used in unintended ways. AES (Advanced Encryption Standard)
media encryption in calls between QSX systems ensures that the content is secure
traveling via the Internet or an IP network. Finally, secure login and encrypted password
exchange for web access allows you to restrict who is able to join meetings.

Input Scaling for QSX to QSX Connections
Specifies whether you want to scale the input resolution
for a QSX to QSX connection. Generally, you would
choose input scaling for QSX to QSX connections when
you wish to obtain a faster frame rate, but are not as
concerned with resolution. The Far End display will try
to scale up to the native resolution of the projector.
(default: No)
(Actual resolution is 1024 x 768)
There are three options:
• No – You do not wish to scale the input.
• 800x600 (SVGA) – You want to scale to an 800x600
image.
• 640x480 (VGA) – You want to scale to a 640x480
image.
Refer to Graphics Display on Page 39 for more
information.
Input Scaling for Web Viewer Content
Specifies whether you want to scale the input resolution
for Web Viewer Content. Generally, you would choose
this in order to reduce bandwidth usage and ensure that
web viewers can see an entire image in their browser
without having to scroll vertically or horizontally to do
so. There are three options:
(default: 800x600 SVGA)
• No – You do not wish to scale the input.
• 800x600 (SVGA) – You want to scale to an 800x600
image.
• 640x480 (VGA) – You want to scale to a 640x480

Enable Load Balancing for Web Viewer
This feature accommodates situations where there is a
limit on available bandwidth. The most common
scenario is when a QSX is both the MCU and the
presenter to additional QSX units as well as web
viewers. In this situation, it may allocate all bandwidth
to the QSX units, leaving none for the web viewers.
Enabling load balancing automatically redirects a web
viewer from the MCU/presenting unit to another QSX
that has available bandwidth.
(default: disabled)
Enable Web Viewer Cascading
This feature accommodates a situation where you have
more than 10 web viewers attempting to join a meeting
where there are also multiple QSX units. By enabling
web viewer cascading, you can have web viewers log
into a QSX other than the presenting or main (MCU)
QSX unit. This requires them to enter the IP address of
the second unit. You can use Web Viewer Cascading to
enable up to 10 web viewers per QSX.
(default: disabled)
Note: If you make bandwidth configuration changes while the QSX is in a Preview or
Send state (yellow or green light, respectively, on the Content Controller), the changes
will not immediately take effect. The QSX will need to be cycled through the Idle state,
then back to Preview. It is recommended that you make bandwidth changes while the
QSX is in Idle.

QSX to Web Viewer Connections
When a web viewer displays the image, it will be displayed at its current resolution. An
800x600 or 640x480 image will display at the center of browser.
Scaling for web viewers will reduce the image size for JPEG compression. This will
immediately affect the loading speed of web viewers and hence the delays of displaying
each image. The higher the resolution, the greater the delay for loading the slide will be.
QSX to QSX Connections
When the QSX displays the remote image, it will always scale the decompressed image
to its own local display resolution.
QSX to QSX connections uses a H263 encoder. Reducing the image size will cause the
H263 to work faster, and hence perform a better compression job and a faster frame rate.

Appendix A – Bandwidth Considerations in QSX
Overview
The QSX 2.0 offers a number of bandwidth options that allow you to optimize its use for
your particular environment. The flowchart below is designed to serve as a guide for
making the proper bandwidth configurations.
This flowchart assumes that you are starting with an idea of how you want to use the
QSX (e.g.- in a Stand Alone mode to share content with web viewers only or in a mixed
environment with other QSX units and web viewers). It also assumes you have a general
idea of the bandwidth that you have available. Based on that information, you can use
this chart to determine the performance with various numbers of participants and what
settings you need to configure on the Web Admin page of the QSX.

This chart was based on a PC input resolution to the QSX of 1024x768. The QSX was
configured for no scaling (1024x768) for H.323 connections and 800x600 for web
viewers.

Additional Information
Maximum Bandwidth Utilization in Low Bandwidth Environments
Most low bandwidth connections (e.g.- DSL) are asymmetrical—transmission speeds are
usually slower than reception speeds. The Transmit and Receive configurations of the
QSX 2.0 use this fact to fully utilize available bandwidth. Look at the following
example, where to QSX units are connected at different rates:
Transmit Speed Receive Speed
384Kbps
128Kbps
1024Kbps
1024Kbps
QSX1
QSX2
In this case, even though the QSX2 has a slower connection, the QSX1 can still transmit
data at 384Kbps and the QSX2 can receive it at that speed. The extra bandwidth
available allows you to share content with people, minimizing delays in delivering that
content to them.
Bandwidth Sharing versus Time Sharing
The QSX allows you to choose between two different modes of bandwidth sharing for
Web Viewers. Depending on the type and speed of connection that participants have to
the meeting, you can use one of these modes to optimize the quality of information
exchange.
Time Sharing
The Time Sharing mode was developed to accommodate web viewers in a low bandwidth
environment.
In the Time Sharing mode, current images will be uploaded to participating web viewers
on a rotating basis. For example, if 32Kbps is available for web viewing and there are
three (3) web viewers connected to the QSX, they will, in turn, use the full 32kbps to
upload images.
No matter how many web viewers are connected, the bandwidth used by each web
viewer will not exceed the maximum allowed value. Moreover, each web viewer still
works under normal bandwidth conditions.
The advantage of Time Sharing is that a web viewer will have the full amount of
bandwidth for a period of time to upload shared content. The disadvantage is that one
slow connection could affect the performance of the rest of the web viewers. If, for
example, the bandwidth allowed is 128Kpbs, but one of three web viewers has a 56Kbps
connection, then the real bandwidth usage will be:
53
Download from Www.Somanuals.com. All Manuals Search And Download.
User 1: 128Kbps
User 2: 128Kbps
User 3: 56Kbps
As a result, the Time Sharing Mode is recommended for an environment with
connections of 128kbps-384kbps. In order to configure the Time Sharing option, follow
these steps:
1. Log on to the QSX Admin Web as described on Page 23.
2. Go to Table of Contents.
3. Go to Admin Settings > Table of Contents > General Settings > Bandwidth.
4. From the pull down menu for the Web Viewer Bandwidth Option, choose “Time
Sharing”.
5. Click the Update button.
Bandwidth Sharing
In the Bandwidth Sharing mode, the total bandwidth allowed for the web viewers is
divided by the total number of participating web viewers. If, for example, there is a total
bandwidth of 1024Kbps and three web viewers, then the maximum amount of bandwidth
that each user will be allocated is:
1024Kbps / 3 web viewers = 340Kbps per web viewer
In the Bandwidth Sharing mode, each web viewer will be allocated a minimum of
32Kbps.
The advantage of the Bandwidth Sharing mode is that each web viewer can work
independently, based on its own bandwidth allocation without being affected by a web
viewer that has a slow connection. The disadvantage is that the sum of the allowed
bandwidth of all web viewers may exceed the configured bandwidth setting, possibly
causing some congestion. The Bandwidth Sharing mode is recommended in corporate
LAN environments where there is little risk of exceeding configured bandwidth.
In order to configure the Bandwidth Sharing option, follow these steps:
1. Log on to the QSX Admin Web as described on Page 23.
2. Go to Table of Contents.
3. Go to Admin Settings > Table of Contents > General Settings > Bandwidth.
4. From the pull down menu for the Web Viewer Bandwidth Option, choose
“Bandwidth Sharing”.
5. Click the Update button.

Load Balancing
In standard usage scenarios, web viewers log in to the presenting QSX to receive higher
quality images and content. In certain situations, the maximum transmission bandwidth
that has been configured will be exceeded because H.323 will use a pre-determined
bandwidth. In these cases, the web viewers are re-directed to a receiving QSX to reduce
the bandwidth usage by the presenting QSX.
The QSX will search all remote parties to determine if there is another QSX unit
participating in the session. For external web viewers participating in the session, the
QSX will also determine if the second QSX unit has NAT enabled.
In this situation, if load balancing is enabled in Time Sharing mode and the QSX has no
more than 64Kbps of bandwidth left from the H.323 connection, it will redirect a web
viewer to the other QSX.
To configure the Bandwidth settings described below, follow these steps:
1. Log on to the QSX Admin Web as described on Page 23.
2. Go to Admin Settings > Table of Contents > General Settings > Bandwidth
3. Choose to either enable or disable Load Balancing for Web Viewers.
4. Click on the Update button.

Appendix B – Additional Web Viewer Information
Web Viewer Cascading
Web Viewer Cascading allows a web viewer to access content from any QSX
participating in a meeting. If the Web Viewer Cascading option is selected, web viewers
can directly login to a QSX which is receiving content rather than being required to login
directly to the presenting QSX or MCU. This allows you to connect up to 10 web
viewers to each QSX participating in a meeting. For example, in the diagram below you
can have up to 10 web participants connecting to the QSX with IP address 156.16.0.180
and 10 more participants connecting to the QSX with IP address 156.16.0.152.
To configure the Web Viewer Cascading settings described below, follow these steps:
1. Log on to the QSX Admin Web as described on Page 23.
2. Go to Admin Settings > Table of Contents > General Settings > Bandwidth
3. Check the box for Enable Web Viewer Cascading.
4. Click on the Update button.

Web Viewing in a Video Environment
If the QSX is connected to a Polycom VSX8000, VSX7000s or a VSX7000e with Visual
Concert, web viewers without video capability can still receive content in a video
environment. In order to do so, they can login directly to the QSX and receive content.
An example of this type of scenario is shown below.

When using the QSX in this scenario, you should ensure that it is configured to auto-
preview content. This means that it will automatically forward content to the local
display, which, in this case, is the VSX unit.
For use of the overall solution, user behavior will not change. When the user wishes to
display content locally or to the far-end video participants, he will simply press the
“Graphics” key on the video system’s remote control. For more information on Polycom
Note: The Polycom Vortex unit shown here is an optional configuration. Polycom
Vortex optimizes audio quality in large conference rooms and other large-room
environments. For more information about the Polycom Vortex system, refer to

Web Viewer Load Balancing
If the presenting QSX has the Load Balance feature enabled, web viewers will be
redirected to a QSX receiving content when bandwidth limitations are reached.
The most common scenario where this happens is when a QSX is both the MCU and the
presenter to additional QSX units as well as web viewers. In this situation, it may
allocate all bandwidth to the QSX units, leaving none for the web viewers. Enabling load
balancing automatically redirects a web viewer from the MCU/presenting unit to another
QSX that has available bandwidth.
External Web Viewers and IP Addresses (NAT)
There may be situations where you want to share content with people outside your
organization’s network. In order to do so, you will need to use Network Address
Translation to link an External IP address to the Internal IP address of your QSX.
Network Address Translation (NAT) is most frequently used to protect IP addresses
inside a company’s network. A NAT-enabled address is linked to an internal, or non-
NAT, IP address so that an outside party can still access that piece of equipment or
location in the network. This allows people to safely cross corporate firewalls without
exposing the network to the outside world.
When a QSX with a NAT-provided IP address is connected to a QSX with an IP address
that has not been translated via NAT, an external web viewer can login to the NAT-
enabled QSX to receive content from the non-NAT QSX. In the example below, the web
participants outside the corporate firewall are accessing the QSX via its External IP
address.

Note: If you are trying to share content between two QSX units that are on either side of
a firewall (or two firewalls if one QSX is inside of one corporation’s firewall and the
other is inside another corporation’s firewall), you will need to use manual IP dialing as
described on Page 12.
Note: If you are using the QSX in a Stand Alone Mode, you will need an External IP
address for web viewers to access. If you are using the QSX from a home office, you
may need to place the unit in the firewall’s DMZ. To determine if you need to place the
QSX in a DMZ, you should contact your Internet Service Provider to a) find out if it is
possible to do so and; b) understand the steps required to configure the system.
Additional Web Viewer Notes
Note: By default, the QSX is configured for Auto Send. In this mode, if the QSX is in
the Preview state (yellow light on the Content Controller or “Preview” in the window of
the VTX1000) content will automatically be send to the first web viewer that logs into
the QSX.
Note: When the QSX is in the Preview state and subsequent web viewers log on, they
will see the QSX splash screen and a message that says “Please Wait for Presentation to
Start”. They will remain in this mode until the presenter presses the Send button on
either the Content Controller or VTX1000 conference phone.
Note: When the last web viewer disconnects from a QSX session, the QSX will
automatically return to the Preview state.

Appendix D—Additional Resolution & Graphics Display
Information
To understand how an image is scaled from the QSX unit’s VGA output to another
device, refer to the following table:
Transmission Scaling
QSX Output Resolution
640 x 480
800 x 600
1024 x 768
1280 x 1024
No Scaling
640 x 480
Scale to 800x 600 Scale to 640 x 480
640 x 480
800 x 600
800 x 600
800 x 600
640 x 480
640 x 480
640 x 480
640 x 480
800 x 600
1024 x 768
1024 x 768
In this table, if you wish to scale VGA output of the QSX from, for example, 1024x768
to 800x600, the resulting scale will be 800x600.
Note: If the resolution of the VGA Output is configured at 1280x1024, the images will
automatically be scaled to 1024x768 for transmission.
Note: The QSX supports local display output resolutions of 1280x1024, 1024x768 and
800x600, but not 640x480. If the output device supports DDC, the highest resolution
will be first selected. If output device does not support DDC, a 1024x768 resolution will
be used.
Note: The QSX output scaling option takes effect after the next presentation starts. If the
option is changed when the QSX is in presentation, it is required to stop presentation and
start again.
When the QSX displays a remote image, it will always scale the decompressed image to
its own local display resolution. The resolution can be one of the following three
resolutions:
• SXGA (1280 x 1024)
• XGA (1024 x 768)
• SVGA (800 x 600)
