dotted-decimal
format Method of representing an IP address or subnet mask using four decimal numbers called octets. Each
octet represents eight bits.
In a class C IP address, the octets are “network.network.network.host.” The first three octets together
represent the network address and the final octet is the host address. In the SBG900 LAN default
configuration, 192.168.100 represents the network address. In the final octet, the host address can be
from 2 to 254.
download To copy a file from one computer to another. You can use the Internet to download files from a server
to a computer. A DOCSIS or Euro-DOCSIS cable modem or gateway downloads its configuration file
from a TFTP server during start-up.
downstream In a cable data network, the direction of data received by the computer from the Internet.
driver Software that enables a computer to interact with a network or other device. For example, there are
drivers for printers, monitors, graphics adapters, modems, Ethernet, USB, HPNA, and many others.
DSL Digital Subscriber Line
DSSS Direct Sequence Spread Spectrum is an IEEE 802.11b RF modulation protocol.
dynamic IP
address An IP address that is temporarily leased to a host by a DHCP server. The opposite of static IP
address.
encapsulate To include data into some other data unit to hide the format of the included data.
encode To alter an electronic signal so that only an authorized user can unscramble it to view the information.
encrypt To encode data.
endpoint A VPN endpoint terminates the VPN at the router so that computers on the SBG900 LAN do not need
VPN client software to tunnel through the Internet to the VPN server.
ESSID The Extended Service Set Identifier or network name is a unique identifier that wireless clients use to
associate with an access point to distinguish between multiple wireless LANs in the same area. All
clients on a wireless LAN must have the same ESSID as the access point. On the SBG900, you can
set the ESSID on the Wireless > NETWORK page.
Ethernet The most widely used LAN type, also known as IEEE 802.3. The most common Ethernet networks are
10Base-T, which provide transmission speeds up to 10 Mbps, usually over unshielded, twisted-pair
wire terminated with RJ-45 connectors. Fast Ethernet (100Base-T) provides speeds up to 100 Mbps.
“Base” means “baseband technology” and “T” means “twisted pair cable.”’
Each Ethernet port has a physical address called the MAC address.
Euro-DOCSIS A tComLabs standard that is DOCSIS adapted for use in Europe
event A message generated by a device to inform an operator or the network management system that
something has occurred.
expansion slot A connection point in a computer where a circuit board can be inserted to add new capabilities.
