Call Session Control Function

The core component of the IMS network. It performs the functions such as registration, authentication, session control, service triggering, topology hiding, QoS control, NAT traversal, and security management.

D

DMZ

demilitarized zone

A buffer area between an insecure system and the secure system and is used to solve the problem of an external network being unable to access an internal network equipped with a firewall. The DMZ is located between the internal network and the external network. The DMZ contains some public server facilities, such as the enterprise Web server and FTP server. The DMZ protects the internal network.

DNS

Domain Name System

A mechanism that maps easy-to-remember domain names to IP addresses recognizable for network devices.

dual stream

During a conference, two channels of video streams can be sent or received simultaneously. One channel is used for transmitting video (such as the video captured by a camera) and the other channel is used for transmitting presentation (such as a computer desktop).

DVI

Digital Visual Interface

DVI-I

Digital Visual Interface-Integrated

E

EUA

Enterprise Unified Address Book

A next-generation address book server launched by Huawei. It provides LDAP-based unified address book services for Huawei videoconferencing and enterprise communication solutions.

G

G.722

Audio codec standard that uses adaptive differential pulse-code modulation (ADPCM). Its data rate is 48 kbit/s, 56 kbit/s, or 64 kbit/s.

G.728

Audio codec standard that uses low-delay code excited linear prediction (LD-CELP). Its data rate is 16 kbit/s.

H

H.239

A standard recommended by ITU-T. It enables a video conference to simultaneously transmit both video and data content (for example, computer desktop).

H.263

A video codec standard for video conferences at low rates. Five formats are available: SQCIF, QCIF, CIF, 4CIF, and 16CIF.

H.264

Compared with H.263, H.264 can provide the same-quality video at half of the bit rate, with strong error resilience.

HD

High Definition

HDMI

High Definition Multimedia Interface

HD display

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

HTTP

Hypertext Transfer Protocol

HTTPS

Hypertext Transfer Protocol over Secure Sockets Layer

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.

I

initiate call

Initiating a call is a process in which the calling party dials the called party's alias or IP address to set up a call and exchange audiovisual information with the called party.

IMS

IP multimedia subsystem

IWB

interactive whiteboard

L

LAN

Local Area Network

LCD

Liquid Crystal Display

LDAP

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.

loopback test

The terminal can transmit audio or video data on a channel as a simulation to test whether the output is satisfactory. A user can perform a local loopback test to check the local network connection or a remote loopback test to check the remote network connection. If a remote loopback test is performed, data is transmitted from the local site to a remote site, and then back to the local site.

M

Net Automatic Transfer-enhancement

P

power on

To start up a computer; to begin a cold boot procedure; to turn on the power.

PPPoE

Point-to-Point Protocol over Ethernet

R

RSE

Recording & Streaming Engine

RTCP

Real-Time Transport Control Protocol

A protocol used to monitor data delivery. RTCP enables the receiver to detect if there is any packet loss and to compensate for any delay jitter.

S

SBC

Session Border Control

SC

Switch Center

The Huawei Switch Center (SC) is a next-generation network switch system that provides H.323 GK, SIP server, and media proxy functions.

schedule conference

Specify the start time and duration of a conference so that the system schedules the conference automatically.

SEC

Super Error Concealment

SIF

Source Input Format

SIP

Session Initiation Protocol

SMC

Service Management Center

A videoconferencing service management system that manages videoconferencing devices (including GKs, MCUs, and participant endpoints) and allocates videoconferencing resources.

SP
