Glossary
Term Denition
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 congured 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. An endpoint may register with more than one alias.
Alternate One or more VCSs congured to support the same zone in order to provide redundancy.
ARQ
Admission Request
An endpoint RAS request to make or answer a call.
Assent TANDBERG’s proprietary protocol for rewall traversal.
Border Controller A TANDBERG device used to control multimedia networks and rewall 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
Command Line Interface
A text-based user interface used to access the VCS.
CPL
Call Processing Language
An XML-based language for dening call handling. Dened by RFC 3880 [5].
DNS
Domain Name System
A distributed database linking domain names to IP addresses.
DNS zone On the VCS, a zone used to congure 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 nally 125125 to
determine which phone line in Lysaker.
ENUM
tElephone NUmber Mapping
A means of mapping E.164 numbers to URIs using DNS.
ENUM zone On the VCS, a zone used to congure 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 rewall 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
Fully Qualied Domain Name
A domain name that species the node’s position in the DNS tree absolutely, uniquely identifying the system or device. Note that in order to use FQDNs instead of
IP Addresses when conguring the VCS, you must have at least one DNS server congured.
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 denes the protocols used for packet-based multimedia communications systems.
