Enabling Basic Mode
Basic Mode is a limited operating mode that uses H.261 for video and G.711
for audio. It provides administrators with a workaround for interoperability
issues that cannot be solved using other methods. The Basic Mode setting stays
in effect until you change it.
To enable Basic Mode in the Polycom HDX system interface:
1. Go to System > Admin Settings > Network > Call Preference.
2. Select Basic Mode.
To enable Basic Mode using the Polycom HDX web interface:
1. On a computer, open a web browser.
2. In the browser address line, enter the system’s IP address, for example,
http://10.11.12.13 , to go to the Polycom HDX web interface.
3. Go to Admin Settings > Network > Call Preference.
4. Select Enable Basic Mode.
Using the Restore Button
You can use the hardware restore button on the Polycom HDX system to reset
the system in one of these ways:
• Restoring configuration—Restores the configuration, which resets most
system settings to default values.
• Factory restore—Completely erases the system and restores it to its
original factory software version and default configuration. If you follow
this procedure while a USB storage device is connected, the system
restores from the USB device instead of the system’s factory partition.
Basic Mode disables many system features such as content sharing, far end
camera control, AES encryption, and advanced audio and video algorithms. Use
Basic Mode only when calling systems that fail to operate properly with these
advanced features.
