Glossary
T
TCP
Transmission Control Protocol
Transport protocol. Session-based transmission protocol: it sets up, moni-
tors, and terminates a connection between sender and recipient for trans-
porting data.
TLS
Transport Layer Security
Protocol for encrypting data transmissions on the Internet. TLS is a superor-
dinated 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 listen to
the call.
Transmission rate
Speed at which data is transmitted 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 two communications partners (applica-
tions).
See also: UDP, TCP, TLS.
U
UDP
User Datagram Protocol
Transport protocol. Unlike TCP, UDP is a non session-based protocol.
UDP does not establish a fixed connection. The data packets ("datagrams")
are sent as a broadcast. The recipient is solely responsible for making sure
the data is received. The sender is not notified about whether it is received
or not.
URI
Uniform Resource Identifier
Character sequence for identifying resources (e.g., e-mail recipient,
www.gigaset.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 dialing 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.
