T

TCP

Transmission Control Protocol

Transport protocol. Session-based transmission protocol: it sets up, monitors and ter-

minates a connection between sender and recipient for transporting data.

TLS

Transport Layer Security

Protocol for encrypting data transfers on the Internet. TLS is a superordinated Transport

protocol.

Toggling

Toggling allows you to switch between two callers or between a conference call and an

individual caller without allowing the waiting caller to screen the call.

Transfer rate

Speed at which data is transferred in the WAN or LAN. The transfer rate is measured in

data units per unit of time (Mbit/s).

Transport protocol

Controls data transport between communication partners (applications).
See also: UDP, TCP, TLS.

U

UDP

User Datagram Protocol

Transport protocol. Unlike TCP, UDP is a non session-based protocol. It does not estab-

lish a fixed connection. The data packets (datagrams) are sent as broadcast. The recipi-

ent is solely responsible for making sure the data is received. The sender is not notified

about whether it is received.

URI

Uniform Resource Identifier

Character sequence for identifying resources (e.g. e-mail recipient, http://siemens.com,

files).
On the Internet URIs are used as a uniform identification for resources. URIs are also

described as SIP addresses.
URIs can be entered in the phone as a number. By dialling a URI you can call an Internet

subscriber with VoIP equipment.

URL

Universal Resource Locator

Globally unique address of a domain on the Internet.
A URL is a subtype of URI. URLs identify a resource by its location on the Internet. For

historical reasons the term is often used as a synonym for URI.

User identification

Name/number combination for access, e.g. to your VoIP account.
