ADSL

 

Asymmetrical Digital Subscriber Line is an asymmetrical technology which means that

 

 

 

 

the downstream data rate of the line is much higher than the upstream data rate. ADSL

 

 

 

 

operates in a frequency range that is above the frequency range of voice services, so the

 

 

 

 

two systems can operate over the same cable.

 

 

 

 

 

 

 

ARP

 

Address Resolution Protocol is a protocol for mapping an Internet Protocol address (IP

 

 

 

 

address) to a physical computer address that is recognized in the local network.

 

 

 

 

 

 

 

ATM

 

Asynchronous Transfer Mode. ATM is a LAN and WAN networking technology that

 

 

 

 

provides high-speed data transfer. ATM uses fixed-size packets of information called

 

 

 

 

cells. With ATM, a high QoS (Quality of Service) can be guaranteed.

 

 

 

 

 

 

 

B

 

 

 

 

 

 

 

 

 

Bandwidth

 

This is the capacity on a link usually measured in bits-per-second (bps).

 

 

 

 

 

 

 

Bit

 

A Binary Digit (either a one or a zero); a single digit number in base-2. A bit is the

 

 

 

 

smallest unit of computerized data.

 

 

 

 

 

 

 

Boot Module

 

Boot Module Commands, available in the debug mode via SMT (some devices may not

 

 

Commands

 

have SMTs), help you initialize the configuration of the basic functions and features of

 

 

 

 

your device(s) such as uploading firmware, changing the console port speed and

 

 

 

 

viewing product-related information.

 

 

 

 

 

 

 

Byte

 

A set of bits that represent a single character. There are eight bits in a byte.

 

 

 

 

 

 

 

C

 

 

 

 

 

 

 

 

 

Command Line

 

A command line interface is a computer environment in which you enter predefined

 

 

Interface

 

commands on the command line to modify, configure and display information about a

 

 

 

 

device or devices. A command line is the line on the display screen where a command

 

 

 

 

is expected. Generally, the command line is the line that contains the most recently

 

 

 

 

displayed command prompt. An interface is a set of commands (for example, a ZyXEL

 

 

 

 

Command Line Interface) or menus (for example, a ZyXEL web configurator) used to

 

 

 

 

communicate with a program. A command-driven interface is an interface in which you

 

 

 

 

enter commands.

 

 

 

 

 

 

 

Crossover

 

A cable that wires a pin to its opposite pin, for example, RX+ is wired to TX+. This

 

 

Ethernet Cable

 

cable connects two similar devices, for example, two data terminal equipment (DTE) or
