TANDBERG VIDEO COMMUNICATION SERVER ADMINISTRATOR GUIDE

Term

Definition

A record

A type of DNS record that maps a domain name to an IPv4 address.

AAAA record

A type of DNS record that maps a domain name to an IPv6 address.

Administrator Policy

In relation to the VCS, the set of rules configured system-wide (either via the web interface or CPL script) that determine the action(s) to be applied to calls matching

a given criteria.

Alias

The name an endpoint uses when registering with the VCS. Other endpoints can then use this name to call it.

Alternate

One or more VCSs configured to support the same zone in order to provide redundancy.

ARQ

An endpoint RAS request to make or answer a call.

Admission Request

Assent

TANDBERG’s proprietary protocol for firewall traversal.

Border Controller

A TANDBERG device used to control multimedia networks and firewall traversal.

Call Policy

The set of rules (administrator policy, user policy and transforms) that are applied to a single call to determine whether and how it is placed.

CLI

A text-based user interface used to access the VCS.

Command Line Interface

CPL

An XML-based language for defining call handling. Defined by RFC 3880 [5].

Call Processing Language

DNS

A distributed database linking domain names to IP addresses.

Domain Name System

DNS zone

On the VCS, a zone used to configure access to endpoints located via a DNS lookup.

E.164

An ITU standard for structured telephone numbers. Each telephone number consists of a country code, area code and subscriber number. For example, TANDBERG’s

European Headquarters’ phone number is +47 67 125125, corresponding to a country code of 47 for Norway, area code of 67 for Lysaker and finally 125125 to

determine which phone line in Lysaker.

ENUM

A means of mapping E.164 numbers to URIs using DNS.

tElephone NUmber Mapping

ENUM zone

On the VCS, a zone used to configure access to endpoints located via ENUM.

External Manager

The remote system that is used to manage endpoints and network infrastructure. The TANDBERG Management Suite (TMS) is an example of an external manager.

Firewall traversal

Crossing a firewall or NAT device.

FindMe™

A TANDBERG feature that allows users to have a single alias on which they can be reached regardless of the endpoint(s) they are currently using.

FQDN

A domain name that specifies the node’s position in the DNS tree absolutely, uniquely identifying the system or device.

Fully Qualified Domain Name

Gatekeeper

A device used to control H.323 multimedia networks. An example is the TANDBERG Gatekeeper.

Gatekeeper Zone

A collection of all the endpoints, gateways and MCUs managed by a single gatekeeper.

H.323

A standard that defines the protocols used for packet-based multimedia communications systems.

HTTP

A protocol used for communications over the internet.

Hypertext Transfer Protocol

HTTPS

A protocol used for secure communications over the internet, combining HTTP with TLS.

Hop count

The number of times a location request may be forwarded to a gatekeeper or proxy before it is deemed to have failed.

ICE

A collaborative algorithm that works together with STUN services (and other NAT traversal techniques) to allow clients to achieve firewall traversal.

Interactive Connectivity Establishment

IETF

An organization that defines (via documents such as RFCs) the protocol standards and best practices relating to the design, use and management of the internet.
