Use the list below to find definitions for technical terms used in this manual.
10BASE-T
IEEE 802.3 specification for 10 Mbps Ethernet over twisted pair wiring.
100BASE-Tx
IEEE 802.3 specification for 100 Mbps Ethernet over twisted pair wiring.
Access Control List (ACL)
An ACL is a database that an Operating System uses to track each user’s access rights to system objects
(such as file directories and/or files).
ADSL
Short for asymmetric digital subscriber line, a technology that allows data to be sent over existing copper
telephone lines at data rates of from 1.5 to 9 Mbps when receiving data (known as the downstream rate) and
from 16 to 640 Kbps when sending data (known as the upstream rate). ADSL requires a special ADSL
modem. ADSL is growing in popularity as more areas around the world gain access.
ARP
Address Resolution Protocol, a TCP/IP protocol used to convert an IP address into a physical address (called
a DLC address), such as an Ethernet address. A host wishing to obtain a physical address broadcasts an ARP
request onto the TCP/IP network. The host on the network that has the IP address in the request then replies
with its physical hardware address. There is also Reverse ARP (RARP) which can be used by a host to
discover its IP address. In this case, the host broadcasts its physical address and a RARP server replies with
the host's IP address.
Auto Uplink
Auto Uplink TM technology (also called MDI/MDIX) eliminates the need to worry about crossover vs.
straight-through Ethernet cables. Auto Uplink TM will accommodate either type of cable to make the right
connection.
Bandwidth
The information capacity, measured in bits per second, that a channel could transmit. Bandwidth examples
include 10 Mbps for Ethernet, 100 Mbps for Fast Ethernet, and 1000 Mbps (I Gbps) for Gigabit Ethernet.
Baud
The signaling rate of a line, that is, the number of transitions (voltage or frequency changes) made per
second. Also known as line speed.
