for a list of other icons you might see.
Showing Content
You can use the Polycom Touch Control Content screen to select, show, and stop content sources. You can access the Content screen while in or out of a call.
You can also use People+Content™ IP to send content from a computer that is connected directly to the Polycom Touch Control.
Cameras
You can use the Polycom Touch Control Cameras screen to select and adjust the main camera or other near-site or far-site video sources. You can access the Cameras screen while in or out of a call.
User Settings
You can use the User Settings screen to configure several features of the Touch Control, such as configuring brightness and volume, setting the availability of the paired Polycom HDX system, allowing far end control of the camera, automatically answering or muting incoming calls, and powering off the Touch Control.
Configurable Remote Control Power Button Behavior
Version 3.0 enables you to configure the behavior of the Power button on the HDX system remote control. You can specify that pressing the Power button powers on or off the HDX system, puts the system to sleep or wakes it, or you can disable the Power button.
Changes to Directory View
Version 3.0 provides the following changes for viewing the directory in the local interface:
[the following items are bulleted as such just for testing]
- • If the directory contains only one folder, that folder is automatically opened when you go to the directory in the local system interface.
- — Administrators can configure whether Favorites are included in the directory of the local system interface.
- » When you create a new contact in the directory, it is added to Favorites.
H.235 Annex D Authentication
H.235 Annex D authentication provides security for H.323-based systems. If H.235 authentication is enabled, the H.323 gatekeeper ensures that only trusted H.323 endpoints are allowed to access the gatekeeper.
H.323 Annex O Dialing
Version 3.0 supports the H.323 Annex O dialing extension, but you need to set up your network infrastructure to support Annex O dialing. Annex O uses URLs and DNS queries to route calls when the HDX system is not registered with a gatekeeper. To use Annex O dialing, enter the dialing information in the form
user@host
on the Place a Call screen.
When the HDX system is registered to a gatekeeper, Annex O is not used. In this case, the entire dial string is routed to the gatekeeper for processing.
Camera Firmware Update for HDX 4000 Systems
Version 3.0 includes a camera firmware update for HDX 4000 series systems. This update improves image quality issues with sharpness and backlit exposure situations.
Default Setting for Outgoing Call Speed
The default preferred speed for placing calls is 512 kbps, which applies to IP call types only (ISDN remains at 128 kbps). This change means that when you upgrade to version 2.6.1 or later, the Select the preferred speeds for placing calls setting reflects the default of 512 .
Polycom HDX System State Changes Through XML API
Polycom CMA system version 5.4 processes some of the Polycom HDX system events and status changes that are sent via the HDX system XML API. This enables the CMA system to report status and events for HDX systems that are outside a firewall such as the Polycom Video Border Proxy (VBP®).
Certificates and Revocation
If your organization requires a secure environment, Polycom recommends that you have a strong understanding of certificate management before you implement these features.
Polycom HDX systems can generate and use certificates to authenticate network connections to and from the Polycom HDX system. The system uses configuration and management techniques typical of public-key infrastructure (PKI) to manage certificates, certificate signing requests (CSRs, sometimes also called unsigned certificates), and revocation lists. ANSI X.509 standards regulate the characteristics of certificates and revocation.
The certificate authority (CA) is the trusted entity that issues, or signs, digital certificates for others, as well as the certificates associated with the CA itself. You can manage certificates and revocation only through the Polycom HDX web interface.
When certificate validation is enabled, the HDX system tries to validate the peer certificate chain on secure connection attempts for the applicable network services. Validation may fail for several reasons, such as certificate expiration or revocation. The HDX system can check revocation status by using certificate revocation lists (CRLs) or the online certificate status protocol (OCSP).
Polycom encourages you to check your system logs daily to ensure that your installed certificates are current.
Finally, in some cases, expired certificates or CRLs might prevent you from accessing the web interface. Polycom enables you to reset your system without certificates, on the local interface, so you can get back into your web interface.
Whitelist
When a whitelist is enabled, the Polycom HDX system enables access to its web interface only by those systems with an IP address that matches the set defined on the HDX system. You can use this feature only through the web interface.
Sessions List
You can use the sessions list to see information about everyone logged in to an HDX system including:
- • Type of connection:
- — Web , when users are logged in through the web interface
- — Serial , when users are logged in through the RS-232 port
- — Local , when users are logged in to the local interface
- • User ID
- • Remote IP address (that is, the computer addresses logged in to the HDX system)
- • Session duration in hours, minutes, and seconds for each user currently logged into the HDX system
- • How long the system has been idle, in seconds
Remote Access Settings
Remote access means using a Polycom HDX system in some way other than through the local interface, such as by using the web, a serial port, or telnet. You can use this new feature to configure the following settings:
Security Banner
In earlier HDX software versions, you could set a security banner only through the local interface. You can still do this, but version 3.0 adds the ability to create banners on the web interface.
Log Management
In earlier HDX software versions, you could use log management to set up and manage logs from the local interface. You can still do this, but version 3.0 adds the ability to set up and manage logs from the web interface. However, to transfer logs manually, you must still use the local interface. Refer to the Administrator’s Guide for Polycom HDX Systems for information about setting up log management.
Security Profiles
Version 3.0 uses five security profiles that determine how administrators and users can use the Polycom HDX system. You can use these profiles to set various security levels for your environment according to the needs of your organization. The system settings you can change after setup depend on which Security Profile you choose.
These are the Security Profile levels:
You set the Security Profile in the setup wizard during system setup. After the system is up and running, you can change the Security Profile setting only by returning to the setup wizard in instances such as these:
External Authentication
Polycom HDX systems support two roles for accessing the system, an admin role and a user role. Admins can perform administrator activities such as changing configuration, as well as user activities such as placing and answering calls. Users can perform only user-type activities.
|
Polycom HDX systems provide two local accounts, one for the user role (by default named
user
) and one with for the admin role (by default named
admin
). The IDs and passwords for these local accounts are stored on the HDX system itself.
With version 3.0, an administrator can also configure HDX systems to grant access using network accounts that are authenticated through an Active Directory (AD) server. In this case, the account information is stored on the AD server and not on the HDX system. The AD administrator assigns accounts to AD groups, one for HDX system admin access and one for user access.
Maintenance Window
Version 3.0 supports the new maintenance window feature that is available in Polycom CMA system version 5.4. This feature enables Polycom CMA system administrators to restrict automatic software updates for Polycom HDX systems to windows of time outside normal system use. An HDX system that has been configured this way will poll the CMA system for automatic updates only during that specified time window.
H.323 over IPv6
Polycom HDX systems now support using H.323 over IPv6 as well as IPv4. DNS entries can be resolved using IPv4, IPv6, or both. Some settings are available only on the web interface.
Account Lockout
The account lockout feature has changed with the introduction of external authentication. When you enable external authentication, the settings on the Account Management screen control both local and web interface login attempts.
For example, if you select 3 for the Lock Account after Failed Logins setting, a user who fails to log in properly twice on the web interface and twice on the local interface is locked out on the fourth attempt. When a user’s total number of incorrect login attempts from the local or the web interface reaches a number greater than what you set here, the user is unable to log in for the amount of time specified.
If the Active Directory server is disabled, the account lockout feature controls lockouts from the local interface only.
Port Lockout
The port lockout feature has also been affected by the introduction of the external authentication feature. As stated in the previous section, when the Active Directory authentication is enabled, remote access through the web interface is controlled by account lockout. When the Active Directory server is disabled, remote access through all ports is controlled by the port lockout feature.
For example, if you select 3 for the Lock Port after Failed Logins setting, a user who fails to log in properly twice through the web interface and twice through SNMP is unable to log in for the amount of time specified in the Port Lock Duration in Minutes setting. However, the user can still log in through the local interface.
Receiving and Sending 1080p Content
The following systems now achieve a maximum frame rate of 15 fps for content in 1080p:
- • Polycom HDX 4000 HD with Hardware Version C
- • Polycom HDX 7000 HD with Hardware Version C
- • Polycom HDX 8000 HD with Hardware Version B
- • Polycom HDX 9006
The following restrictions apply to receiving and sending 1080p content:
- • The call speed must be greater than or equal to 832 kbps and camera video quality must be set to sharpness.
- • This feature is not supported when hosting an internal multipoint call.
- • This feature is supported only on the DVI-I input port, for example, camera 4 on the HDX 8000. This feature is not supported on camera 1 or camera 2.
- • People On Content™ is not supported at 1080p.
- • If you chose to enable the Allow Video Display on Web setting, the Web Director’s near snapshot image will not update when sending 1080p content.
Please refer to your RMX documentation or contact your Polycom representative for information about which RMX releases support sending and receiving 1080p content.

Video conferencing systems use a variety of algorithms to compress audio and video. In a call between two systems, each end transmits audio and video using algorithms supported by the other end. In some cases, a system may transmit a different algorithm than it receives. This process occurs because each system independently selects the optimum algorithms for a particular call, and different products may make different selections. This process should not affect the quality of the call.
Polycom HDX systems are tested extensively with a wide range of products. The following list is not a complete inventory of compatible equipment. It simply indicates the products that have been tested for compatibility with the HDX systems software 3.0.1 release.
