Key Features
Video Conferencing is communication between two or more groups across different locations using telecommunications channels for fully interactive video and audio or one-way video and two-way audio. Audio Conferencing is a teleconferencing mode that allows individuals and groups to communicate through voice alone using telephone or VoIP conference system.
Conference Type
Video Conference
Defines the maximum transfer rate in IP technology (H.323)

Max Data Rate ISDN
2 Mbps
Describes the networking connection standard that the device uses to communicate with other networking device(s).
Networking Interfaces
1 x RJ 45 - 10/100 Base-TX (Ethernet), 1 x PBX Interface (RJ 11)
LCD displays have low energy requirements and are generally easy to read. TFT is a type of LCD. Compared to other types of LCDs, TFTs feature excellent image quality and response time (using somewhat more energy), and are generally found in more expensive models. Monochrome (black & white) LCDs usually have both a backlight as well as a reflective backing, allowing them to be equally usable in both bright light as well as complete darkness.
Standards
Universal formats that allows video systems of differing manufacturers to communicate with each other. All conferencing systems use standards that must match in order for the streams to be translated by conferencing equipment in different locations.
Supported Standards
H.231, H.233, H.234, H.235-v3, H.225, H.239, H.241, H.243, H.281, H.245, H.320, H.323, SIP, H.221, H.224
Short for compressor/decompressor, a codec is any technology for compressing and decompressing data. Codecs can be implemented in software, hardware, or a combination of both. Some popular codecs for computer video include MPEG, Indeo and Cinepak. In telecommunications, (short for coder/decoder) a device that encodes or decodes a signal. For example, telephone companies use codecs to convert binary signals transmitted on their digital networks to analog signals converted on their analog networks.
Codecs
G.711, G.729A, G.722, H.263+, H.261, H.264, G.728, H.263++, G.722.1
The phone supported networking protocols, these protocols provide the phone a 'language' for communication with the network
Protocols
TCP, UDP, FTP, SNMP, RTP, HTTP, DHCP, Telnet, ARP
Quality of Service (QoS) is the idea that transmission rates, error rates, and other characteristics can be measured, improved and to some extent, guaranteed in advance. QoS is of particular concern for the continuous transmission of high-bandwidth video and multimedia information. Transmitting this kind of content generally is difficult in public networks using ordinary "best effort" protocols.

There are various types of Video Formats that may be built into a video conferencing systems: \r\n \r\n NTSC (National Television System Committee) is the analog television broadcasting standard used widely in North America. It is referred to as a 525-line standard, but actually displays only 480 lines. NTSC is to be replaced with new DTV (Digital TV) standards in the coming years. \r\n \r\n The PAL (Phase Alternating Line) standard was introduced in the early 1960's and was implemented widely in Europe. It has a wider channel bandwidth than NTSC as it runs on 635 lines. \r\n \r\n VGA (Video Graphics Array) is an analog graphics standard introduced with the IBM PS/2 series that supports a maximum resolution of 640 x 480 pixels in 16 colors out of a palette of 262,144 colors. \r\n \r\n SVGA (Super Video Graphics Array) a graphics standard for a computer monitors that offers greater resolution than VGA. There are several supported levels including 800 x 600 pixels, 1024 by 768 pixels, 1280 by 1024 pixels; and 1600 by 1200 pixels. \r\n \r\n XGA (Extended Graphic Array) is a graphics standard developed by IBM that allows the display of 1024 x 768 pixels with up to 65, 535 colors. \r\n \r\n SXGA (Super Extended Graphic Array) is a extremely high-resolution specification for computer and projector displays and is most frequently required in intricate workstation-design setting where maximum detail is essential.
Video Formats
PAL, NTSC, VGA, SVGA, XGA
Other Features
Defines the power supply method, some devices are able to receive power supplied via a networking cable (USB / CAT 5). Another method is via IEEE 802.3af technology that supplies 48V (DC) from a networking device such as a switch that supports PoE (Power over Ethernet) or PoL (Power over LAN) standards.
