built-in MCU

A built-in unit of an endpoint, by using the built-in MCU, the endpoint can hold a multipoint conference that supports multiple functions, such as site access, video exchange, audio mixing, data processing, and signaling interaction.



Customer-premises Equipment

The equipment located at an end-user's premises. Most CPEs are telephones or other service equipment. A CPE can be a Mobile Station (MS) or a Subscriber Station (SS). An MS is mobile equipment, and an SS is fixed equipment.

chair site

A site that has chair control rights.


An IP multimedia session that has two or more participants. Each conference has a focus and can be identified uniquely.



A European standard for high-speed data transmission at 2.048 Mbit/s. It provides thirty-two 64 kbit/s channels. A time division multiplexing frame is divided in to 32 timeslots numbered from 0 to 31. Timeslot 0 is reserved for frame synchronization, and timeslot 16 is reserved for signaling transmission. The rest 30 timeslots are use as speech channels. Each timeslot sends or receives an 8-bit data per second. Each frame sends or receives 256-bit data per second. 8000 frames will be sent or received per second. Therefore the line data rate is 2.048 Mbit/s.



File Transfer Protocol over SSL

An extension to the commonly used File Transfer Protocol (FTP) that adds support for the Transport Layer Security (TLS) and the Secure Sockets Layer (SSL) cryptographic protocols.


HD display

An HD plasma TV that is used to display the video from a telepresence codec.


Hypertext Transfer Protocol Secure

An HTTP protocol that runs on top of transport layer security (TLS) and Secure Sockets Layer (SSL) for secured transactions. It is used to establish a reliable channel for encrypted communication and secure identification of a network web server. HTTPS consists of communication over Hypertext Transfer Protocol (HTTP) within a connection encrypted by Transport Layer Security, or its predecessor, Secure Sockets Layer. The main motivation for HTTPS is authentication of the visited website and protection of the privacy and integrity of the exchanged data.



Internet Information Services

Microsoft's brand of a Web server software, utilizing the Hypertext Transfer Protocol (HTTP) to deliver World Wide Web documents. It incorporates various functions for security, allows for CGI programs, and also provides Gopher and FTP services.


Internet Protocol version 4

The current version of the Internet Protocol (IP). IPv4 utilizes a 32bit address which is assigned to hosts. An address belongs to one of five classes (A, B, C, D, or E) and is written as 4 octets separated by periods and may range from through to Each IPv4 address consists of a network number, an optional subnetwork number, and a host number. The network and subnetwork numbers together are used for routing, and the host number is used to address an individual host within the network or subnetwork.


Internet Protocol version 6

An update version of IPv4, which is designed by the Internet Engineering Task Force (IETF) and is also called IP Next Generation (IPng). It is a new version of the Internet Protocol. The difference between IPv6 and IPv4 is that an IPv4 address has 32 bits while an IPv6 address has 128 bits.


Integrated Services Digital Network


Interactive voice response

A telephone-based value-added voice service. Telephone users can dial a number specified by a carrier, and then follow the instructions to listen to, demand, and send voice information as required, or participate in interactive services, such as chats and making friends.



Lightweight Directory Access Protocol

A network protocol based on TCP/IP, which allows access to a directory system agent (DSA). It involves some reduced functionality from X.500 Directory Access Protocol (DAP) specifications.

left screen

The screen of the left HD display in the telepresence system and displays the video from the left codec.


multipoint call

A site makes calls to multiple sites, to hold a conference that has multiple participants.



Picture in Picture

The Picture in Picture (PIP) service allows subscribers to view a full screen window (main window) and a small window (PIP window) at the same time on the screen when watching a live TV channel. The current channel is played in the main window and another channel is played in the PIP window.

point-to-point call

A site makes a call to another site, to hold a conference that has two participants.


During a conference, the local site shares the content input from a computer with remote sites, such as an excel file, a diagram, or slides.


right screen

The screen of the right HD display in the telepresence system and displays the video from the right codec.



Simple Network Management Protocol

An IETF protocol for monitoring and managing systems and devices in a network. The data being monitored and managed is defined by a MIB. The functions supported by the protocol are the request and retrieval of data, the setting or writing of data, and traps that signal the occurrence of events."


Secure Real-time Transport Protocol

A real time transport protocol with enhanced security and encryption mechanism-based RTP.


A group of IP systems with IP connectivity, which can be achieved independent of SP networks.

site template

A site template is used to classify sites into different groups. In a site template, the sites are identified by the predefined site names. After a site template is defined, you can find the name of the template in the relevant drop-down list box from the conference control page. You can find a specific site quickly using a site template.



The Huawei telepresence system provides users a comfortable videoconferencing environment in which they can have true-to-life and face to face remote conferences.

touch panel

The touch panel is connected to the telepresence system wirelessly. Without cable restriction, users can use the touch panel conveniently. From the touch panel, users can perform operations, such as dialing a number, calling a contact, answering or rejecting a call, controlling a conference, and switching the display mode.



Wireless Local Area Network

A hybrid of the computer network and the wireless communication technology. It uses wireless multiple address channels as transmission media and carriers out data interaction through electromagnetic wave to implement the functions of the traditional LAN.


Wireless Fidelity

A short-distant wireless transmission technology. It enables wireless access to the Internet within a range of hundreds of feet wide.
