Prestige 782R G.SHDSL Router

 

 

 

 

 

 

 

 

Task Force) RFC-1661 through 1663. PPP provides router-to-router, host-to-router,

 

 

 

 

and host-to-host connections.

 

 

 

 

 

 

 

Promiscuous

 

Actively capturing packet information from a network. Most computers only collect

 

 

Packet Capture

 

packets specifically addressed to them. Promiscuous packet capture acquires all

 

 

 

 

network traffic it can regardless of where the packets are addressed.

 

 

 

 

 

 

 

Protocol

 

A “language” for communicating on a network. Protocols are sets of standards or rules

 

 

 

 

used to define, format and transmit data across a network. There are many different

 

 

 

 

protocols used on networks. For example, most web pages are transmitted using the

 

 

 

 

HTTP protocol.

 

 

 

 

 

 

 

Protocol Filters

 

Your Prestige uses Protocol Filters to decide whether or not to allow passage of a data

 

 

 

 

packet and/or to make a call. Protocol filters act on IP/IPX packets and can serve as a

 

 

 

 

limited firewall.

 

 

 

 

 

 

 

Proxy Server

 

A server that performs network operations in lieu of other systems on the network.

 

 

 

 

Proxy Servers are most often used as part of a firewall to mask the identity of users

 

 

 

 

inside a corporate network yet still provide access to the Internet. When a user

 

 

 

 

connects to a proxy server, via a web browser or other networked application, he

 

 

 

 

submits commands to the proxy server. The server then submits those same

 

 

 

 

commands to the Internet, yet without revealing any information about the system that

 

 

 

 

originally requested the information. Proxy servers are an ideal way to also have all

 

 

 

 

users on a corporate network channel through one point for all external

 

 

 

 

communications. Proxy servers can be configured to block certain kinds of

 

 

 

 

connections and stop some hacks.

 

 

 

 

 

 

 

PSTN

 

Public Switched Telephone Network was put into place many years ago as a voice

 

 

 

 

telephone call-switching system. The system transmits voice calls as analog signals

 

 

 

 

across copper twisted cables from homes and businesses to neighborhood COs

 

 

 

 

(central offices); this is often called the local loop. The PSTN is a circuit-switched

 

 

 

 

system, meaning that an end-to-end private circuit is established between caller and

 

 

 

 

callee.

 

 

 

 

 

 

 

PVC

 

Permanent Virtual Circuit. A PVC is a logical point-to-point circuit between customer

 

 

 

 

sites. PVCs are low-delay circuits because routing decisions do not need to be made

 

 

 

 

along the way. Permanent means that the circuit is preprogrammed by the carrier as a

 

 

 

 

path through the network. It does not need to be set up or torn down for each session.

 

 

 

 

 

 

 

ras

 

This is the name of the firmware on the Prestige. Renaming may be necessary when

 

 

 

 

uploading new firmware to the Prestige.

 

 

 

 

 

 

 

RBOC

 

Regional Bell Operating Company. There are currently seven regional telephone

 

 

 

 

companies that were created by the AT&T divestiture.

 

 

 

 

 

 

 

RFC

 

A Request for Comments is an Internet formal document or standard that is the result

 

 

 

 

of committee drafting and subsequent review by interested parties. Some RFCs are

 

 

 

 

informational in nature. Of those that are intended to become Internet standards, the
