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 prese[...]

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 QS X-to-QSX meeting. First, the direct connection eliminates the need to [...]

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 m ore information about Polycom’s video system s, refer to the Ad ministrator’s Guide for the respective product[...]

QSX Usage with Polycom MGC The QSX system can be connected to an MG C bridge to incre ase 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 a nd configured. For more information about Polycom’s MG[...]

After the MGC call has connected to the QSX, the QSX unit will not con nect to any other QSX or video units. Other non-QSX units must access the co ntent via the MGC bridge. If the QSX is already in a call with anothe r unit (i.e. – QSX or video unit) and the MG C calls it, it will reject the MGC call. Note: It is strongly recommended that you on[...]

2. Step 1 is all that is requir ed to set up your QSX system. If you plan to use it with a Polycom conference phone, please conn ect the following cables as well: • 8-wire cable for phone console. Connect th e 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 co[...]

Set a Static IP Addres s Usin g HyperTerminal If you need to assign a static IP address to the QSX system, follow these steps before you try to set up and use the QSX system: 1. Connect a straight-through serial cable from the QSX system to a computer. 2. Power on the QSX base with only the pow er cable and serial cable connected. 3. Start the Hype[...]

Note: If you hold the Content butt on during boot up of the QSX un it, it will force the unit into DHCP mode. That will cause the QSX unit to seek an IP address from the DHCP server on your network. Changing QSX to Dynamic IP Mode By default, the QSX is configured to obtain an IP address from a DHCP server in your network. If you have configured it[...]

Appendix A – Bandwid th Considerations in QSX Overview The QSX 2.0 offers a number of bandwidth op tions 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 t[...]

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 Transm it and Receive configurations of the QSX 2.0 use this fact to fully utilize av ailable bandwidth. Look at the following example, whe[...]

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 Content[...]

Load Balancing In standard usage scenarios, web viewers log in to the presenting QSX to receive higher quality images and content. In certain s ituations, the m aximum transm ission bandwidth that has been configured will be exceeded becaus e H.323 will use a pre-determined bandwidth. In these cases, the web viewers ar e re-directed to a receiving [...]

Appendix B – Additional W eb V iewer Information Web Viewer Cascading Web Viewer Cascading allows a web vi ewer to access content from any QSX participating in a meeting. If the Web View er Cascading option is selected, web viewers can directly login to a QSX which is receivi ng content rather than being required to login directly to the presenti[...]

Web Viewing in a Video Environment If the QSX is connected to a Polycom VS X8000, VSX7000s or a VSX7000e with Visual Concert, web viewers without video capabi lity can still receive conten t in a video environment. In order to do so, they can logi n directly to the QSX and receive con ten t. An example of this type of scenario is shown below. W e b[...]

Web Viewer Load Balancing If the presenting QSX has the Load B alance feature enabled, web viewers will be redirected to a QSX receiving content when bandwidth lim itations 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 m [...]

Note: If you are trying to share content between tw o QSX units that are on either side of a firewall (or two firewalls if one QSX is in side of one corporation’s firew all 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 Al one Mo[...]
