TFTP	Trivial File Transfer Protocol

	Transfer Protocol (FTP) but not as capable or secure.

TTL	Time To Live
	A field in an IP packet that limits the life span of that packet.
	Originally meant as a time duration, the TTL is usually
	represented instead as a maximum hop count; each router that
	receives a packet decrements this field by one. When the TTL
	reaches zero, the packet is discarded.
twisted pair	The ordinary copper telephone wiring long used by telephone
	companies. It contains one or more wire pairs twisted together to

	In homes, it is most often installed with two pairs. For Ethernet
	LANs, a higher grade called Category 3 (CAT 3) is used for
	10BASE-T networks, and an even higher grade called Category
	5 (CAT 5) is used for 100BASE-T networks. See also 10BASE-T,
	100BASE-T, Ethernet.
upstream	The direction of data transmission from the user to the Internet.
VLAN	Virtual Local Area Network
WAN	Wide Area Network
	Any network spread over a large geographical area, such as a
	country or continent. With respect to the SL-1000, WAN refers to
