an ISDN terminal. See also NT.
Telnet Telecommunication Network (Telnet) is a network protocol. It en-
ables communication with another, remote device in the network, e.
g. PCs, routers, etc.
TFTP The Trivial File Transfer Protocol (TFTP) regulates the transmission
of files. Compared with FTP, there is no option to display data, issue
permissions or authenticate users.
Tiger 192 Tiger 192 is a hash function that generates a 192 bit hash value
(checksum). See also Hash.
Time slot A time slot is a period of time which is permanently assigned within
a transmission frame, and is usually equivalent to one transmission
channel.
TLS See SSL.
TOS Type of Service (TOS) is a field in the header of IP data packets. It
specifies the priority of the data packet. See also QoS.
Traceroute Traceroute is used to determine which routers will be used to route
data packets to the queried destination host.
Trigger This refers to a trigger impulse.
Triple DES See DES.
TTL The Time to live (TTL) is the configured period of validity of a data
packet. With the Internet Protocol (IP), TTL specifies how many
hops a data packet may pass. The maximum value is 255 hops. The
TTL is reduced by 1 with each hop. If a data packet has not yet
reached its destination when its TTL expires, it is discarded.
Twofish Twofish is an encryption method (see Cipher). Twofish uses a fixed
block length of 128 bits. The key length is 128, 192 or 256 bits.
U-ADSL Universal Asymmetric Digital Subscriber Line (UADSL) is a DSL
variant. It was developed as ANSI T1.413 and standardised as
G.992.2. U-ADSL enables different communication technologies to
be used in parallel, e. g. ISDN and POTS, and does not require a
splitter.
UDP The User Datagram Protocol (UDP) is a connectionless protocol. It
works on the transport layer of the OSI model. With a connection-
less protocol, no control is integrated for delivering the packet. The
