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.

camera

A device for recording visual images in the form of photographs, movie film, or video signals.

chair site

A site that has chair control rights.

D

DMZ

Demilitarized Zone

A buffer area between an insecure system and the secure system and is used to solve the problem that the external network equipped with a firewall cannot access the internal network server. The DMZ is located between the internal network and the external network. In the DMZ, some public server facilities, such as the enterprise Web server and FTP server, can be located. The DMZ effectively protects the internal network.

DNS

Domain Name System

A mechanism of mapping easy-to-remember domain names to IP addresses recognizable for network devices.

DST

Daylight Saving Time

DTMF

Dual Tone Multiple Frequency

Multi-frequency signaling technology for telephone systems. According to this technology, standard set combinations of two specific voice band frequencies, one from a group of four low frequencies and the other from a group of four high frequencies, are used.

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 have simultaneous transmission of 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 characteristics.

H.323 protocol

A communication control protocol defined by the International Telecommunication Union (ITU). It offers multimedia services in the packet-switched (PS) network. Call control is an essential component in H.323 and is used to establish point-to-point media sessions and multi-point media conferences.

HD

high definition

HD display

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

HDMI

high definition multimedia interface

HEVC

High Efficiency Video Coding

High Efficiency Video Coding, also known as H.265, is a next-generation digital video compression format developed by the ITU-T Video Coding Experts Group (VCEG) together with the ISO/IEC JTC1 Moving Picture Experts Group (MPEG). Compared with its previous generation (H.264), HEVC offers a higher data compression ratio.

I

ICE

intelligent concept extraction

IMS

IP multimedia subsystem

L

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.

SIF

Source Input Format

SIP URI

It is used for SIP to identify users. A SIP URI includes a user name and a domain name. It can also contain other parameters.

SIP trunk

A packet trunk. Different from a physical channel defined by a circuit relay, a SIP trunk defines a logical channel, which solves the issues about interoperability authentication and call addressing between the local office and the peer office.

SMC

Service Management Center

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

SP

Service Provider

A service provider (SP) is defined as a company or organization, making use of an electronics communications network or part thereof to provide a service or services on a commercial basis to third parties.

SRTP

Secure Real-time Transport Protocol

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

SSH

Secure Shell

A set of standards and an associated network protocol that allows establishing a secure channel between a local and a remote computer. A feature to protect information and provide powerful authentication function for a network when a user logs in to the network through an insecure network. It prevents IP addresses from being deceived and simple passwords from being captured.

STUN

Simple Traversal of UDP through NAT

Switch Center
