DSL Access Multiplexor. The piece of equipment at the telephone company central office that provides the 
ADSL signal.

DHCP is a protocol for assigning dynamic IP addresses to devices on a network. With dynamic addressing, 
a device can have a different IP address every time it connects to the network. In some systems, the device's 
IP address can even change while it is still connected. DHCP also supports a mix of static and dynamic IP 
addresses. Dynamic addressing simplifies network administration because the software tracks IP addresses 
rather than requiring an administrator to manage the task. A new computer can be added to a network 
without the hassle of manually assigning it a unique IP address. 

Encapsulating Security Payload.

The Extended Service Set Identification (ESSID) is a thirty-two character (maximum) alphanumeric key 
identifying the wireless local area network. 

A LAN specification developed jointly by Xerox, Intel and Digital Equipment Corporation. Ethernet 
networks transmit packets at a rate of 10 Mbps.

An Ethernet system that is designed to operate at 100 Mbps.

The process of screening a packet for certain characteristics, such as source address, destination address, or 
protocol. Filtering is used to determine whether traffic is to be forwarded, and can also prevent unauthorized 
access to a network or network devices.

When a frame is received on an input port on a switch, the address is checked against the lookup table. If the 
lookup table has recorded the destination address, the frame is automatically forwarded on an output port.
