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.
