U
UDP
User Datagram Protocol) - protocoll used to send data packets over non-
secure communication lines without a connection. This means that
successful transmission is dependent on the application and is therefore not
always guaranteed. UDP itself does not verify whether data has been trans-
mitted 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 by DNS servers, for example.
U

via a single twin wire. System phones of the COMfortel series are directly
connected to the internal U

the U
P0
port the via a U
