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.
