Necessary changes in the Viewstation hardware cause a minor difference in operation when using the snapshot features. All snapshot capabilities remain consistent, but in certain cases, the video preview prior to capturing the snapshot may be passed on to the far site. See the feature limitations section for details. State-of-the-Art Feature Review Superior Video with Support for the H.264 Standard .. The H.264 standard provides 15 fps video at line rates below 192 Kbps and 30 fps at line rates from 192 to 384 Kbps. H.264 video is supported in both IP and ISDN calls. .. Available as an option for existing systems. For information about adding the H.264 option to currently deployed systems, please contact your Polycom distributor. .. Interoperates with other systems using H.264 standard implementations. .. You can configure the system to use standards-based 50/60 fields video for calls at 512 Kbps and above. .. Error Concealment allows IP calls to provide high-quality audio and video even over networks experiencing heavy traffic. AES Encryption Support Features of the encryption option include: .. Standards-based encryption at all speeds up to 2Mbps, in IP and ISDN calls. .. On-screen indicators show whether encryption is in use during calls. .. Automatic encryption of point-to-point and multipoint calls is available. .. Support for People+Content calls. Video and graphics streams are both encrypted. .. ITU standard key exchange and key management. .. Support for National Institute of Standards and Technology (NIST) approved, FIPS 197 compliant 128-bit AES encryption with extended Diffie-Hellman key distribution recommended by the H.235 (version 3) standard for IP networks and the H.233/H.234 standard for ISDN networks. .. Interoperates with VSX, iPower, and MGC. .. Interoperates with other systems using the H.233/H.234/H.235 (version 3) standard encryption implementation. For information about purchasing the encryption option, please contact your Polycom distributor. Easy System Configuration and Management .. The Address Book Utility is available through the web interface. This utility allows the system administrator to .. back up systems’ address books in a central location, .. edit address books, and .. distribute the same address book to several systems. .. System administrators can make chair control functionality inaccessible to users remotely using the PMAC application. .. IP systems can be configured to get the time from a time server. This allows the system to record call times accurately in the CDR if the time server is available. .. The alternate gatekeeper feature allows the ViewStation EX, ViewStation FX, or VS4000 system to dynamically update its configured gatekeeper IP address when the gatekeeper changes IP address (for example, when a system administrator redirects network traffic to a different gatekeeper during maintenance and service). .. System administrators can set QoS values (IP precedence or DiffServ) separately for video, audio, and far-site camera control. .. Third-party applications for using and managing the systems require the same passwords as the ViewStation web interface. Easy Software Updates and Upgrades The ViewStation EX, ViewStation FX, and VS4000 systems include one-year hardware warranty (30-day return upon receipt at factory) and 90-day software warranty. For the first year, software updates (bug fixes and maintenance releases) and software upgrades (feature releases) are also included. Co...
