Prestige 782R G.SHDSL Router

 

 

 

 

 

 

 

 

 

were designed for departments, although the latter accurately describes a LAN as well.

 

 

 

 

LANs have different topologies, the most common being the linear bus and the star

 

 

 

 

configuration.

 

 

 

 

 

 

 

LATA

 

Local Access and Transport Area is a geographic territory used primarily by local

 

 

 

 

telephone companies to determine charges for intrastate calls. As a result of the Bell

 

 

 

 

divestiture, switched calls that both begin and end at points within the LATA

 

 

 

 

(intraLATA) are generally the sole responsibility of the local telephone company.

 

 

 

 

Conversely, calls that cross outside the LATA (interLATA) are passed on to an Inter

 

 

 

 

eXchange Carrier (IXC).

 

 

 

 

 

 

 

LEC

 

Local Exchange Carrier. The local phone companies – either a Regional Bell

 

 

 

 

Operating Company (RBOC) or an independent phone company (e.g., GTE) – that

 

 

 

 

provide local transmission services.

 

 

 

 

 

 

 

LED

 

Light Emitting Diode. LEDs are visual indicators that relay information about the status

 

 

 

 

of specific Prestige functions to the user by lighting up, turning off or blinking. LEDs

 

 

 

 

are usually found on the front panel of the physical device. Examples include Status,

 

 

 

 

Power and System LEDS.

 

 

 

 

 

 

 

Linux

 

A version of the UNIX operating system designed to run on IBM Compatible

 

 

 

 

computers.

 

 

 

 

 

 

 

LLC-Multiplexing

 

One VC carries multiple protocols with protocol identifying information being contained

 

 

 

 

in each packet header. Despite the extra bandwidth and processing overhead, this

 

 

 

 

method my be advantageous if it is not practical to have a separate VC for each

 

 

 

 

carried protocol, eg., if charging heavily depends on the number simultaneous VCs.

 

 

 

 

 

 

 

Loop-reach

 

Loop reach defines speed that can be attained at various distances. This is very

 

 

 

 

important for DSL technology as distance from the CO (Central Office) influences

 

 

 

 

attainable speeds.

 

 

 

 

 

 

 

MAC

 

On a local area network (LAN) or other network, the Media Access Control (MAC)

 

 

 

 

address is your computer's unique hardware number. (On an Ethernet LAN, it is the

 

 

 

 

same as your Ethernet address.) The MAC layer frames data for transmission over the

 

 

 

 

network, then passes the frame to the physical layer interface where it is transmitted

 

 

 

 

as a stream of bits.

 

 

 

 

 

 

 

Name Resolution

 

The allocation of an IP address to a host name. See also DNS.

 

 

 

 

 

 

 

NAT

 

Network Address Translation is the translation of an Internet Protocol address used

 

 

 

 

within one network to a different IP address known within another network. See also

 

 

 

 

SUA.

 

 

 

 

 

 

 

NDIS

 

Network Driver Interface Specification is a Windows® specification for how

 

 

 

 

communication protocol programs (such as TCP/IP) and network device drivers should

 

 

 

 

communicate with each other.
