Terminology and Functions
U
Time and Call Allowance Account
Each telephone can be credited a certain amount of time using a time account. When the time
credit is used up, it becomes no longer possible to make external calls on the corresponding
telephone until the credit is reset.
A call allowance account is a restricted amount of currency units that is configured for each
telephone. When these units are used up, it becomes no longer possible to make external calls
on the corresponding telephone until the credit is reset.
Transfer
A communication partner can be transferred or connected to an internal or external subscriber.
Transferring Without Announcement
This describes a type of transfer where external calls are transferred to internal subscribers.
The caller is put through to the desired subscriber without an announcement.
U
UDP
UDP (User Datagram Protocol) is used to send data packet over non-secure communication
lines without a connection. This means that successful transmission is dependent on the appli-
cation and is therefore not always guaranteed. UDP itself does not verify whether data has
been transmitted successfully. When a UDP packet is sent, the sender cannot assume that the
packet will indeed arrive at the recipient. This particular protocol needs only a small amount of
additional information, and results in a better data throughput rate in a well-functioning network,
e.g., on a LAN. UDP is used, e.g., for the DNS (Domain Name Server).
UPnP
UPnP (Universal Plug and Play) is a standard for networking various devices on home
networks. It ensures that computers, televisions, multimedia equipment and household appli-
ances can be automatically detected by each other without the user having to spend a lot of
time configuring settings.
