Glossary
Term
Telnet
A network protocol used on the internet or Local Area Networks (LANs).
TLS
A protocol that provides secure communications over the internet.
Transport Layer Security
TMS
A TANDBERG product used for the management of video networks.
TANDBERG Management Suite
TMS Agent
A VCS feature that allows TANDBERG Movi™ v2.0 clients registered to the VCS to be provisioned with phonebook and configuration information by connecting to the
VCS rather than directly to TMS. See the
Transform
In relation to the VCS, the process of changing or replacing the alias being searched for.
Traversal call
Any call where both signaling and media are routed through the local VCS. See the section
Traversal client
A traversal entity on the private side of a firewall. Examples are a TANDBERG Gatekeeper or TANDBERG VCS Control.
Traversal client zone
A zone on a VCS traversal client that has been used to configure a connection to a particular traversal server.
Traversal server
A traversal entity on the public side of a firewall. Examples are the TANDBERG Border Controller and the TANDBERG VCS Expressway.
Traversal server zone
A zone on a VCS Expressway that has been used to configure a connection to a particular traversal client.
Traversal Subzone
A conceptual subzone through which all traversal calls are deemed to pass; used to manage the bandwidth of traversal calls.
Traversal-enabled endpoint
Any endpoint that supports the Assent and/or ITU H.460.18 and H.460.19 standards for firewall traversal. This includes all TANDBERG MXP endpoints.
UA
A SIP device used to make and receive calls.
User Agent
UDP
A communication protocol defined by
User Datagram Protocol
URI
A formatted string used to identify a resource, typically on the internet.
Uniform Resource Identifier
User Policy
The set of rules that determine the action(s) to be applied to calls for a particular user or group.
VCS
A generic term for the TANDBERG product which acts as a gatekeeper and SIP Proxy/Server.
Video Communications Server
VCS Control
A VCS whose main function is to act as a gatekeeper, SIP proxy and firewall traversal client. This system will generally be located within the firewall.
VCS Expressway
A VCS with the same functionality as a VCS Control that can also act as a firewall traversal server. This will generally be located outside the firewall.
Zone
Zones are used on the VCS to define and configure connections to locally registered and external systems and endpoints. The Local Zone refers to all the locally
registered endpoints and systems, and consists of configurable subzones. External zones are used to configure connections to external systems with which the VCS
has a neighbor, traversal client or traversal server relationship, and to configure the way in which the VCS performs ENUM and DNS searches.
