virtually any cable or DSL modem that supports Ethernet.
What are the advanced features of the Router? The Router's advanced features
include IP Filtering, Port Range Forwarding, Dynamic Routing, Static
Routing, DMZ hosting, and MAC Address Cloning.
What is the maximum number of VPN sessions allowed by the Router?
One VPN session at a time.

Appendix B: Glossary

10BaseT - An Ethernet standard that uses twisted wire pairs.
100BaseTX - IEEE physical layer specification for 100 Mbps over two pairs of
Category 5 UTP or STP wire.
1000BASE-T - Provides half-duplex (CSMA/CD) and full-duplex 1000 Mbps
Ethernet service over Category 5 links as defined by ANSI/TIA/EIA-568-A.
Topology rules for 1000BASE-T are the same as those used for 100BASE-T.
Category 5 link lengths are limited to 100 meters by the ANSI/TIA/EIA-568-
A cabling standard. Only one CSMA/CD repeater will be allowed in a collision
domain.
Adapter - Printed circuit board that plugs into a PC to add to capabilities or
connectivity to a PC. In a networked environment, a network interface card
(NIC) is the typical adapter that allows the PC or server to connect to the
intranet and/or Internet.
Auto-negotiate - To automatically determine the correct settings. The term is
often used with communications and networking. For example, Ethernet
10/100 cards, hubs, and switches can determine the highest speed of the node
they are connected to and adjust their transmission rate accordingly.
Backbone – The part of a network that connects most of the systems and net-
works together and handles the most data.
Bandwidth - The transmission capacity of a given facility, in terms of how
much data the facility can transmit in a fixed amount of time; expressed in bits
per second (bps).
Bit – A binary digit. The value—0 or 1—used in the binary numbering system.
Also, the smallest form of data.
Boot – To cause the computer to start executing instructions. Personal comput-
ers contain built-in instructions in a ROM chip that are automatically executed
on startup. These instructions search for the operating system, load it, and pass
control to it.
Bottleneck – A traffic slowdown that results when too many network nodes try
to access a single node, often a server node, at once.
Bridge - A device that interconnects different networks together.
