Glossary

Router	A special purpose, dedicated computer that attaches to two or more networks and
	forwards packets from one to the other.
Routing Table	A table that stores information about possible destinations for packets being routed
	through the HotWire DSLAM and identifies the next hop address to which to send the
	packet.
RTU	Remote Termination Unit. A device, such as the HotWire 5446 RTU, that is installed at the
	end-user site (customer premises). The RTU connects to the local loop to provide
	high-speed Internet or Intranet connectivity to the HotWire DSLAM.
s1b	Interface name of the card's interface to the DSLAM system backplane bus.
s1c	Interface name of a DSL card's DSL port #1.
s1d	Interface name of a DSL card's DSL port #2.
s1e	Interface name of a DSL card's DSL port #3.
s1f	Interface name of a DSL card's DSL port #4.
SNMP	Simple Network Management Protocol. A software program housed within a device to
	provide SNMP functionality. Each agent stores management information and responds to
	the manager's request for this information.
SNMP Agent	A software program housed within a device to provide SNMP functionality. Each agent
	stores management information and responds to the manager's request for this
	information.
SNMP Trap	A notification message to the SNMP manager when an unusual event occurs on a network
	device, such as a reinitialization.
Static Route	A permanent entry into the routing table that is manually entered. Static routes take
	precedence over routes chosen by dynamic routing protocols.
Subnet Address Mask	A bit mask used to select bits from an IP address for subnet addressing. The mask is
	32 bits long and selects the network portion of the IP address and one or more bits of the
	local portion. This allows a subnet to be identified so that an IP address can be shared on
	a LAN.
TCP	Transmission Control Protocol. An Internet standard transport layer protocol defined in
	STD 7, RFC 793. It is connection-oriented and stream-oriented.
TCP/IP	Transmission Control Protocol/Internet Protocol. The dominant protocol in the worldwide
	Internet, TCP allows a process on one machine to send data to a process on another
	machine using the IP protocol. TCP can be used as a full-duplex or one-way simplex
	connection.
Telnet	A simple remote terminal protocol that is part of the Transmission Control Protocol/Internet
	Protocol (TCP/IP) protocol suite. Telnet allows the user of one host computer to log into a
	remote host computer, and interact as a normal terminal user for that host.
Terminal Emulation	Software that allows a session to work as if it was running a specific type of terminal; e.g.,
	VT100 or 3270 to logically connect your terminal to a mainframe computer.
TFTP	Trivial File Transfer application. A standard TCP/IP protocol that allows simple file transfer
	to and from a remote system without directory or file listing.
TraceRoute	A program that prints the path to a destination. It is a superset of the Ping utility used to
	evaluate the hops taken from one end of a link to another.
Upstream	In extended networks, the direction in which diagnostic messages flow from the final
	tributary diagnostic modem to the intermediate links to the diagnostic control site.
XTACACS	See Authentication Server.
