-----T-----
telnet. IP protocol that lets a user on one host establish and use a virtual
terminal connection to a remote host.
TR-064. TR-064 is a LAN-side DSL Gateway configuration specification; an
extension of UPnP. It defines more services to locally manage a Gateway.
TR-069. TR-069 is a WAN-side DSL Gateway Management specification; pro-
vides services similar to UPnP and TR-064. The communication between a
Gateway and management agent in UPnP and TR-064 is strictly over the
LAN, whereas the communication in TR-069 is over the WAN link for some
features and over the LAN for others. TR-069 allows a remote Auto-Config
Server to provision and manage a Gateway.
twisted pair. Cable consisting of two copper strands twisted around each
other. The twisting provides protection against electromagnetic interference.
-----U-----
UTP. Unshielded twisted pair cable.
-----V-----
VDSL. Very high rate Digital Subscriber Line. VDSL transmits high speed
data over short reaches of twisted-pair copper telephone lines, with a range
of speeds depending upon actual line length. Both data channels will be
separated in frequency from bands used for POTS and ISDN, enabling ser-
vice providers to overlay VDSL on existing services. At present the two high
speed channels will also be separated in frequency.
VJ. Van Jacobson. Abbreviation for a compression standard documented in
RFC 1144.
VLAN. Virtual Local Area Network. A network of computers that behave as if
they are connected to the same wire even though they may be physically
located on different segments of a LAN. VLANs are configured in software
rather than hardware.
