Prestige 1600 Universal Access Concentrator

 

 

 

 

 

 

FCC

 

The FCC (Federal Communications Commission) is in charge of allocating the electromagnetic

 

 

 

 

spectrum and thus the bandwidth of various communication systems.

 

 

 

 

 

 

Filters

 

Your Prestige uses filters to decide whether to allow passage of a data packet and/or to make a

 

 

 

 

call. There are two types of filter applications: data filtering and call filtering.

 

 

 

 

 

 

Flash memory

 

The nonvolatile storage that can be electrically erased and reprogrammed so that data can be

 

 

 

 

stored, booted and rewritten as necessary.

 

 

 

 

 

 

Frame Relay

 

Frame relay is a metropolitan and wide area networking solution that implements a form of

 

 

 

 

packet-switching technology. It routes frames of information from source to destination over a

 

 

 

 

switching network.

 

 

 

 

 

 

FTP

 

File Transfer Protocol. The Internet protocol (and program) used to transfer files between hosts.

 

 

 

 

 

 

Gateway

 

A gateway is a computer system or other device that acts as a translator between two systems

 

 

 

 

that do not use the same communication protocols, data formatting structures, languages,

 

 

 

 

and/or architecture.

 

 

 

 

 

 

HDLC

 

HDLC (High-level Data Link Control) is a bit-oriented (the data is monitored bit by bit), link layer

 

 

 

 

protocol for the transmission of data over synchronous networks.

 

 

 

 

 

 

hop count

 

A measure of distance between two points on the Internet. It is equivalent to the number of

 

 

 

 

gateways that separate the source and destination.

 

 

 

 

 

 

Host

 

Any computer on a network that is a repository for services available to other computers on the

 

 

 

 

network. It is quite common to have one host machine provide several services, such as WWW

 

 

 

 

and USENET.

 

 

 

 

 

 

IANA

 

Internet Assigned Number Authority acts as the clearinghouse to assign and coordinate the use

 

 

 

 

of numerous Internet protocol parameters such as Internet addresses, domain names, protocol

 

 

 

 

numbers, and more. The IANA Web site is at http://www.isi.edu/iana.

 

 

 

 

 

 

ICMP

 

Internet Control Message Protocol is a message control and error-reporting protocol between a

 

 

 

 

host server and a gateway to the Internet. ICMP uses Internet Protocol (IP) datagrams, but the

 

 

 

 

messages are processed by the TCP/IP software and are not directly apparent to the application

 

 

 

 

user.

 

 

 

 

 

 

IDSL

 

Uses ISDN transmission technology to deliver data at 128kbps into an IDSL "modem bank"

 

 

 

 

connected to a router.

 

 

 

 

 

 

IGMP

 

IGMP (Internet Group Management Protocol) is a session-layer protocol used to establish

 

 

 

 

membership in a multicast group - it is not used to carry user data.

 

 

 

 

 

 

Internet

 

(Lower case i) Any time you connect two or more networks together, you have an internet.

 

 

 

 

 

 

Internet

 

(Upper case I) The vast collection of inter-connected networks that all use the TCP/IP protocols

 

 

 

 

and that evolved from the ARPANET of the late 60’s and early 70’s.

 

 

 

 

 

 

Intranet

 

A private network inside a company or organization that uses the same kinds of software that

 

 

 

 

you would find on the public Internet, but that is only for internal use.

 

 

 

 

 

 

IP

 

Internet Protocol (currently IP version 4, or IPv4), is the underlying protocol for routing packets

 

 

 

 

on the Internet and other TCP/IP-based networks.

 

 

 

 

 

 

IP Multicast

 

Traditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender to 1

 

 

 

 

recipient) or Broadcast (1 sender to everybody on the network). IP Multicast is a third way to

 

 

 

 

deliver IP packets to a group of hosts on the network - not everybody.

 

 

 

 

 

 

IP Policy Routing

 

IPPR provides a mechanism to override the default routing behavior and alter the packet

 

 

(IPPR)

 

forwarding based on the policy defined by the network administrator. Policy-based routing is

 

 

 

 

applied to incoming packets on a per interface basis prior to the normal routing.

 

 

 

 

 

 

IPCP (PPP)

 

IP Control Protocol allows changes to IP parameters such as the IP address.

 

 

 

 

 

 

ISO

 

International Standards Organization. A voluntary, non-treaty organization founded in 1946,

 

 

 

 

responsible for creating international standards in many areas, including computers and

 

 

 

 

communications.

 

 

 

 

 

 

ISP

 

Internet Service Provider: an organization offering and providing Internet services to the public

 

 

 

 

and having its own computer servers to provide the services offered.

 

 

 

 

 

 

ITU-T

 

International Telecommunications Union, Standardization Sector. ITU-T is the

 

 

 

 

telecommunication standardization sector of ITU and is responsible for making technical
