xii Preface

Prestige 642 PPPoE Modem

What is DSL?

DSL (Digital Subscriber Line) technology enhances the data capacity of the existing telephone line running
between the local telephone company switching offices and most homes and offices. While the wire itself can
handle higher frequencies, the telephone switching equipment is designed to cut off signals above 4,000Hz to
filter noise from the voice line. DSL services are either symmetrical (traffic flows at the same speed in both
directions) or asymmetrical (the downstream capacity is higher than the upstream capacity).

As the carrying distance increases, data rates decrease. That means that users who are beyond a certain
distance from the telephone company’s central office may not be able to obtain the higher speeds for DSL
maximum transmission distances. A DSL connection is a point-to-point dedicated circuit, meaning that the
link is always up and there is no dialing required.

What is ADSL?

ADSL is an asymmetrical technology, meaning that the downstream data rate is much higher than the
upstream data rate. This works well for a typical Internet session in which more information is downloaded,
e.g., from Web servers, than is uploaded. 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.

bios filters are turned on when PPPoE is selected.

1.3 Applications for the Prestige 642 PPPoE Modem

1.3.1 Internet Access

The Prestige is the ideal high-speed Internet access solution. Your Prestige supports TCP/IP protocol, which
the Internet commonly uses. It is compatible with all major ADSL DSLAM (Digital Subscriber Line Access
Multiplexer) providers. A DSLAM is a rack of ADSL line cards with data multiplexed into a backbone
network interface/connection (e.g., T1, OC3, DS3, ATM or Frame Relay). Think of it as the equivalent of a
modem rack for ADSL. A typical Internet Access application is shown below.

The following figure shows the rear panel connections of your Prestige.

Figure 2-2 Rear Panel Connections of the P642

2.2.1 Connecting the ADSL Line

Connect the Prestige directly to the wall jack using the included ADSL cable. Connect a microfilter between
the wall jack and your telephone(s) (see the Connecting a Microfilter figure). Microfilter(s) act as low pass
filters (voice transmission takes place in the 0 to 4KHz bandwidth). A microfilter is an optional purchase.

2.2.2 Connecting a Computer to the Prestige 10/100M LAN Port

Ethernet 10Base-T/100Base-T networks use Shielded Twisted Pair (STP) cable with RJ-45 connectors that
look like a bigger telephone plug with 8 pins. Use the crossover cable (red tag) to connect your Prestige to a
computer directly. Use a straight-through Ethernet cable (white tag) to connect to an external hub and then
connect one end of a straight-through Ethernet cable (white tag) from the hub to the NIC (Network Interface
Card) on the computer.

2.2.3 Connecting the Power Adapter to your Prestige

Connect the power adapter to the port labeled POWER on the rear panel of your Prestige.

After the Prestige has been successfully connected to your network, you can make future changes to the
configuration through the telnet application.

2.4 Connecting a POTS Splitter

This is for the Prestige following the Full Rate (G.dmt) standard only. One major difference between ADSL
and dial-up modems is the optional telephone splitter. This device keeps the telephone and ADSL signals
separated, giving them the capability to provide simultaneous Internet access and telephone service on the
same line. Splitters also eliminate the destructive interference conditions caused by telephone sets. The
purchase of a POTS splitter is optional.

Noise generated from a telephone in the same frequency range as the ADSL signal can be disruptive to the
ADSL signal. In addition the impedance of a telephone when off-hook may be so low that it shunts the
strength of the ADSL signal. A POTS splitter will filter the telephone signals before combining the ADSL
and telephone signals transmitted and received. The issues of noise and impedance are eliminated with a
single POTS splitter installation.

A telephone splitter is easy to install as shown in the following figure.

3.3.1 Wizard Setup — PPPoE Modem Screen

The screen shown next appears if you selected PPPoE Modem from the initial Wizard screen and allows
you to enter Internet Access information in one screen. Before you configure your Prestige for Internet
access, you need to collect your Internet account information from your ISP and telephone company. Refer to
the next table for a list of required account information.

A Note about IP Adressess.

Every machine on the Internet must have a unique address. If your networks are isolated from the Internet,
e.g., only between your two branch offices, you can assign any IP addresses to the hosts without problems.
However, the Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of IP
addresses specifically for private networks:

10.0.0.0 - 10.255.255.255

172.16.0.0 - 172.31.255.255

192.168.0.0 - 192.168.255.255

3-4 Web Configurator

Prestige 642 PPPoE Modem

You can obtain your IP address from the IANA, from an ISP or assigned from a private network. If you
belong to a small organization and your Internet access is through an ISP then ISP can provide you with the
Internet addresses for your local networks. On the other hand, if you are part of a much larger organization
then you should consult your network administrator for the appropriate IP addresses.

Regardless of your particular situation, do not create an arbitrary IP address;

always follow the guidelines above. For more information on address assignment,

please refer to RFC 1597, Address Allocation for Private Internets and RFC 1466,

Guidelines for Management of IP Address Space.

A Note about VPI and VCI Numbers

Be sure to use the correct Virtual Path Identifier (VPI) and Virtual Channel Identifier (VCI) numbers
supplied by the telephone company. The valid range for the VPI is 1 to 255 and for the VCI is 32 to 65535 (0

3.4.3 Advanced Setup — LAN Screen

Click the Advanced Setup link and then click the LAN link to display the screen shown next.

DHCP

DHCP (Dynamic Host Configuration Protocol) allows individual clients (computers) to obtain the TCP/IP
configuration at start-up from a centralized DHCP server. The Prestige has built-in DHCP server capability,
enabled by default, which means it can assign IP addresses, an IP default gateway and DNS servers to
Windows 98, Windows NT and other systems that support the DHCP client. The Prestige can also act as a
surrogate DHCP server where it relays IP address assignments from the actual DHCP server to clients.

IP Pool Setup

The Prestige is pre-configured with a pool of 32 IP addresses starting from 192.168.1.33 to 192.168.1.64 for
the client computers. This leaves 31 IP addresses, 192.168.1.2 to 192.168.1.32 (excluding the Prestige itself
which has a default IP of 192.168.1.1), for other server computers, e.g., server for mail, FTP, telnet, web,
etc., that you may have.

DNS

DNS Server Address DNS (Domain Name System) is for mapping a domain name to its corresponding IP
address and vice versa, e.g., the IP address of www.zyxel.com is 204.217.0.2. The DNS server is extremely
important because without it, you must know the IP address of a computer before you can access it. The DNS
server addresses that you enter in the DHCP setup are passed to the client computers along with the assigned
IP address and subnet mask. There are two ways that an ISP disseminates the DNS server addresses. The first
is for an ISP to tell a customer the DNS server addresses, usually in the form of an information sheet, when

Web Configurator 3-11

Prestige 642 PPPoE Modem

s/he signs up. If your ISP does give you the DNS server addresses, enter them in the DNS Server fields in
DHCP Setup, otherwise, leave them blank. If the Primary and Secondary DNS Server fields in DHCP Setup
are not specified, i.e., left as 0.0.0.0, the Prestige tells the DHCP clients that it itself is the DNS server. When
a computer sends a DNS query to the Prestige, the Prestige forwards the query to the real DNS server learned
through IPCP and relays the response back to the computer. Please note that DNS proxy works only when the
ISP uses the IPCP DNS server extensions. It does not mean you can leave the DNS servers out of the DHCP
setup under all circumstances.

IP Address

If the ISP did not explicitly give you an IP network number, then you most likely have a single user account
and the ISP will assign you a dynamic IP address when the connection is established. If this is the case, it is
recommended that you select a network number from 192.168.0.0 to 192.168.255.0 (ignoring the trailing
zero) and you must enable the Single User Account feature of the Prestige (it is enabled by default).

The subnet mask specifies the network number portion of an IP address. Your Prestige will compute the
subnet mask automatically based on the IP address that you entered. You don't need to change the subnet
mask computed by the Prestige unless you are instructed to do otherwise.

3.4.5 Advanced Setup — NAT (Network Address Translation) Applications

Click the Advanced Setup link and then click the NAT Applications link to display the screen shown next.

Network Address Translation (NAT)

Typically, if there are multiple users on the LAN that want concurrent access to the Internet, you must lease a
block of legal or globally unique IP addresses from an ISP. The NAT feature lets you enjoy the same benefits

3-14 Web Configurator

Prestige 642 PPPoE Modem

as having multiple legal addresses, but only pay for one IP address, thus saving significantly on subscription
fees (check with your ISP before you enable this feature). The IP address for the NAT can be either fixed or
dynamically assigned by the ISP. In addition, you can designate servers, e.g., a web server and a Telnet
server, on your local network and make them accessible to the outside world (see below). If you do not define
a server, NAT offers the additional benefit of firewall protection. If no server is defined, all incoming
inquiries will be filtered out by your Prestige, thus preventing intruders from probing your network. Your
Prestige accomplishes address sharing by translating the internal LAN IP addresses to a single address that is
globally unique on the Internet. For more information on IP address translation, refer to RFC 1631 - The IP

Network Address Translator (NAT).

Multiple Servers behind NAT

Even though NAT makes your whole inside network appear as a single computer to the outside world, A
service is identified by the port number; the following table shows the most common services and their
corresponding port numbers.

Table 3-7 Common Services and Corresponding Port Numbers

SERVICES PORT NUMBER

FTP (File Transfer Protocol) 21

Telnet 23

SMTP (Simple Mail Transfer Protocol) 25

DNS (Domain Name System) 53

HTTP (Hyper Text Transfer Protocol or WWW Web) 80

PPTP (Point-to-Point Tunneling Protocol) 1723

So, if you have a web server at IP address 192.168.1.2 and a FTP server at IP address 192.168.1.3, then you
need to specify port 80 (web) for the server at IP address 192.168.1.2 and port 21 (FTP) for the FTP server at
IP address 192.168.1.3.

A server can support more than one service, e.g., a server can provide both FTP and DNS service, while
another provides only web service. Furthermore, since you need to specify the IP address of a server in the
Prestige, a server must have a fixed IP address and not be a DHCP client whose IP address potentially
changes each time it is turned on.

In addition to servers for specific services, NAT supports a default server. A service request that does not
have a server explicitly designated for it is forwarded to the default server. If the default server is not defined,
the service request is simply discarded. To make a server visible to the outside world, specify the port
number of the service in the Port Number field and the inside IP address of the server in the Server IP
Address field.

The Prestige has some of the more popular applications already pre-configured. Select an application from
the drop-down list box and the corresponding port number should display in the Port Number field. To

4.2 Command Structure

4.2.1 Conventions for Using CI Commands

General Conventions

• CI commands may be typed in a variety of ways depending on what you want to configure, display, etc.

The conventions for typing in most CI commands are shown next.

command <interface|device> subcommand [parameter]
command subcommand [parameter]
?|help
command ?|help
commmand subcommand ?|help

Syntax Conventions

• CI command keywords are in regular courier font and should be typed in as they appear or in

abbreviated form (see the next section).

• Required fields (parameters) in a CI command are enclosed in “<>” brackets. For example,

P642ME-13> set ppp password <xxxxxxxx> <VC#>

• Optional fields (parameters) in a CI command are enclosed in “[]” brackets. For example,

P642ME-13>device dial [node#]

• The “|” symbol is shorthand for the word “or”. For example, sys log online [on|off]

4-2 Command Line Interface

Prestige 642 PPPoE Modem

4.2.2 Using Abbreviated CI Commands

Some CI commands have abbreviated forms that allow quicker Prestige configuration (and fewer
keystrokes). Type enough of a CI command to distinguish it from other CI commands. For example, typing
the sys v CI command is the same as typing sys version. On the other hand, typing the sys trc CI
command will cause the Prestige to temporarily hang because this command can’t distinguish itself from
sys trcdisp, sys trc log or sys trcpacket CI commands. Shown next, are some examples
of abbreviated CI commands.

Chapter 5

Firmware and Configuration Maintenance

This chapter tells you how to back up and restore your configuration file as well as upload new

firmware and a new configuration file.

5.1 Filename Conventions

The configuration file (often called the romfile or rom-0) contains the factory default settings in the menus
such as password, DHCP Setup, TCP/IP Setup, etc. It arrives from ZyXEL with a rom filename extension.
Once you have customized the Prestige's settings, they can be saved back to your computer under a filename
of your choosing.

ZyNOS (ZyXEL Network Operating System sometimes referred to as the “ras” file) is the system firmware
and has a “bin” filename extension. With many ftp and tftp clients, the filenames are similar to those seen
next.

ftp> put firmware.bin ras

This is a sample ftp session showing the transfer of the computer file " firmware.bin" to the Prestige.

ftp> get rom-0 config.cfg

This is a sample ftp session saving the current configuration to the computer file config.cfg.

If your [t]ftp client does not allow you to have a destination filename different than the source, you will need
to rename them as the Prestige only recognizes “rom-0” and “ras”. Be sure you keep unaltered copies of both
files for later use.

The following table is a summary. Please note that the internal filename refers to the filename on the Prestige
and the external filename refers to the filename not on the Prestige, that is, on your computer, local network
or ftp site and so the name (but not the extension) will vary. After uploading new firmware see the ZyNOS
F/W Version field in the System Status screen to confirm that you have uploaded the correct firmware
version.

FTP over WAN will not work if security level 2 or 3 is enabled.

5.2 Backup Configuration

Backup is highly recommended once your Prestige is functioning properly. FTP and TFTP are the preferred
methods for backing up your current configuration to your computer since FTP and TFTP are faster. Any
serial communications program should work fine; however, you must use Xmodem protocol to perform the
download/upload and you don’t have to rename the files (see section 5.1).

Please note that terms “download” and “upload” are relative to the computer. Download means to transfer
from the Prestige to the computer, while upload means from your computer to the Prestige.

5.2.1 Backup Configuration Using FTP

Follow the instructions shown next.

5.2.2 Using the FTP command from the DOS Prompt

Step 1. Launch the FTP client on your computer.

Step 2. Enter “open”, followed by a space and the IP address of your Prestige.

Step 3. Press [ENTER] when prompted for a username.

Step 4. Enter your password as requested (the default is 1234).

Step 5. Enter “bin” to set transfer mode to binary.

5-2 Firmware and Configuration File Maintenance

Prestige 642 PPPoE Modem

Step 6. Use “get” to transfer files from the Prestige to the computer, for example, “get rom-0 config.rom”

transfers the configuration file on the Prestige to your computer and renames it “config.rom”. See
earlier in this chapter for more information on filename conventions.

Step 7. Enter “quit” to exit the ftp prompt.

Step 8. Enter “atgo” to restart the Prestige.

Firmware and Configuration File Maintenance 5-3

Prestige 642 PPPoE Modem

5.2.3 Backup Configuration Using TFTP

The Prestige supports the up/downloading of the firmware and the configuration file using TFTP (Trivial File
Transfer Protocol) over LAN. Although TFTP should work over WAN as well, it is not recommended.

To use TFTP, your computer must have both telnet and TFTP clients. To backup the configuration file,
follow the procedure shown next:

Step 1. Use telnet from your computer to connect to the Prestige and log in. Because TFTP does not have

any security checks, the Prestige records the IP address of the telnet client and accepts TFTP
requests only from this address.

Step 2. Enter the Command Line Interface by following the instructions in the Command Line Interface

chapter.

Step 3. Enter command “sys stdio 0” to disable the console timeout, so the TFTP transfer will not be

interrupted. Enter command “sys stdio 5” to restore the five-minute console timeout (default)
when the file transfer is complete.

Step 4. Launch the TFTP client on your computer and connect to the Prestige. Set the transfer mode to

binary before starting data transfer.

Step 5. Use the TFTP client (see the example below) to transfer files between the Prestige and the

computer. The file name for the configuration file is “rom-0” (rom-zero, not capital o).

Note that the telnet connection must be active and the Prestige in CI mode before and during the TFTP
transfer. For details on TFTP commands (see following example), please consult the documentation of your
TFTP client program. For UNIX, use “get” to transfer from the Prestige to the computer and “binary” to set
binary transfer mode.

5.2.4 TFTP Command Example

The following is an example tftp command:

TFTP [-i] host get rom-0 config.rom

where “i” specifies binary image transfer mode (use this mode when transferring binary files), “host” is the
Prestige IP address, “get” transfers the file source on the Prestige (rom-0 name of the configuration file on
the Prestige) to the file destination on the computer and renames it config.rom.

Third Party TFTP Clients

The following table describes some of the fields that you may see in third party TFTP clients.

5.3 Restore Configuration

This section shows you how to restore a previously saved configuration to the Prestige and upload a
configuration file. Note that this function erases the current configuration before restoring a previous back up
configuration; please do not attempt to restore unless you have a backup configuration file stored on disk.

FTP and TFTP are the preferred methods for restoring your current computer configuration to your Prestige
since FTP and TFTP are faster. Please note that you must restart the system after the file transfer is
complete.

5.4.2 TFTP File Upload

The Prestige also supports the uploading of firmware files using TFTP (Trivial File Transfer Protocol) over
LAN. Although TFTP should work over WAN as well, it is not recommended.

To use TFTP, your computer must have both telnet and TFTP clients. To transfer the firmware and the
configuration file, follow the procedure shown next.

Step 1. Use telnet from your computer to connect to the Prestige and log in. Because TFTP does not have

any security checks, the Prestige records the IP address of the telnet client and accepts TFTP
requests only from this address.

Step 2. Enter the Command Line Interface by following the instructions in the Command Line Interface

chapter.

Step 3. Enter the command “sys stdio 0” to disable the console timeout, so the TFTP transfer will not be

interrupted. Enter “command sys stdio 5” to restore the five-minute console timeout (default)
when the file transfer is complete.

Step 4. Launch the TFTP client on your computer and connect to the Prestige. Set the transfer mode to

binary before starting data transfer.

Step 5. Use the TFTP client (see the example below) to transfer files between the Prestige and the

computer. The file name for the firmware is “ras”.

Note that the telnet connection must be active and the Prestige in CI mode before and during the TFTP
transfer. For details on TFTP commands (see following example), please consult the documentation of your
TFTP client program. For UNIX, use “get” to transfer from the Prestige to the computer, “put” the other way
around, and “binary” to set binary transfer mode.

TFTP Upload Command Example

The following is an example tftp command:

TFTP [-i] host put firmware.bin ras

where “i” specifies binary image transfer mode (use this mode when transferring binary files), “host” is the
Prestige’s IP address, “put” transfers the file source on the computer (firmware.bin – name of the firmware
on the computer) to the file destination on the remote host (ras - name of the firmware on the Prestige).

Commands that you may see in third party TFTP clients are listed earlier in this chapter.

5.4.3 Uploading Files Via Console Port

FTP or TFTP are the preferred methods for uploading firmware to your Prestige. However, if your network is
down, uploading files is only possible with a direct connection to your Prestige via the console port.
Uploading files via the console port under normal conditions is not recommended since FTP or TFTP is

faster. Any serial communications program should work fine; however, you must use the Xmodem protocol
to perform the upload.

Example Xmodem Firmware Upload Using HyperTerminal

Step 1. Enter the Command Line Interface by following the instructions in the Command Line Interface

chapter.

Step 2. Enter “r s”.

Step 3. Enter “atur”.

Step 4. Run the HyperTerminal program. Click Transfer, then Send File as shown in the following

screen.

Step 5. After the "Starting Xmodem upload" message appears, activate the Xmodem protocol on your

computer. Follow the procedure as shown previously for the HyperTerminal program. The
procedure for other serial communications programs should be similar.

Step 6. Click Transfer, then Send File to display the following screen.

Type the firmware file’s
location, or click
Browse to look for it.

Choose the Xmodem
protocol.

Then click Send.

Figure 5-8 Example Xmodem Upload

After the firmware upload process has completed, the Prestige will automatically restart.

VPI & VCI

This appendix describes VPI and VCI.

ATM is a connection-oriented technology, meaning that it sets up virtual circuits over which end systems
communicate. The terminology for virtual circuits is as follows:

z Virtual Channel Logical connections between end stations

z Virtual Path A bundle of virtual channels

Think of a virtual path as a cable that contains a bundle of wires. The cable connects two points, and wires
within the cable provide individual circuits between the two points. In an ATM cell header, a VPI (Virtual
Path Identifier) identifies a link formed by a virtual path and a VCI (Virtual Channel Identifier) identifies a
channel within a virtual path. The VPI and VCI are identified and correspond to termination points at ATM
switches as shown. Your telephone company should supply you with these numbers.

Digital Subscriber Line technologies enhance the data capacity of the existing twisted
pair wire that runs between the local telephone company switching offices and most
homes and offices. There are actually seven types of DSL service, ranging in speeds
from 16 Kbits/sec to 52 Mbits/sec. The services are either symmetrical (traffic flows at
the same speed in both directions) or asymmetrical (the downstream capacity is higher
than the upstream capacity). DSL connections are point-to-point dedicated circuits,
meaning that they are always connected There is no dial-up. There is also no
switching, which means that the line is a direct connection into the carrier’s frame
relay, ATM (Asynchronous Transfer Mode) or Internet-connect system.

A Digital Subscriber Line Access Multiplexor (DSLAM) is a network device, usually
at a telephone company central office, that receives signals from multiple customer
Digital Subscriber Line connections and puts the signals on a high-speed backbone line
using multiplexing techniques. Depending on the product, DSLAM multiplexers
connect DSL lines with some combination of asynchronous transfer mode ATM, frame
relay or IP networks.

Frequently Asked Questions. FAQs are documents that list and answer the most
common questions on a particular subject.

The FCC (Federal Communications Commission) is in charge of allocating the
electromagnetic spectrum and thus the bandwidth of various communication systems.

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.

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.

Internet Assigned Number Authority acts as the clearing house to assign and coordinate
the use of numerous Internet protocol parameters such as Internet addresses, domain
names, protocol numbers, and more. Use a search engine to find the current IANA web

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 of simultaneous VCs.

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.

On a local area network (LAN) or other network, the MAC (Media Access Control)
address is a computer's unique hardware number. (On an Ethernet LAN, it's 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.

Multiplexors or MUXs, as they are often called, are devices that combine signals from
various sources such as PBX (Private Branch Exchange), asynchronous terminals or a
bridge connected to a WAN. A multiplexor transmits these signals as a single data
stream over a digital line. Multiplexors, among other tasks, conserve bandwidth.

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.

Any time you connect two or more computers together, allowing them to share

An Internet port refers to a number that is part of a URL, appearing after a colon (:),
directly following the domain name. Every service on an Internet server listens on a
particular port number on that server. Most services have standard port numbers, e.g.
Web servers normally listen on port 80.

An interface on a computer for connecting peripherals or devices to the computer. A
printer port, for example, is an interface that is designed to have a printer connected to
it. Ports can be defined by specific hardware (such as a keyboard port) or through
software.

Plain Old Telephone Service is the analog telephone service that runs over copper
twisted-pair wires and is based on the original Bell telephone system. Twisted-pair
wires connect homes and businesses to a neighborhood central office. This is called the
local loop. The central office is connected to other central offices and long-distance
facilities.

Point to Point Protocol. PPP encapsulates and transmits IP (Internet Protocol)
datagrams over serial point-to-point links. PPP works with other protocols such as IPX
(Internetwork Packet Exchange). The protocol is defined in IETF (Internet Engineering
Task Force) RFC 1661 through 1663. PPP provides router-to-router, host-to-router, and
host-to-host connections.

PPPoE

Protocol

PSTN

F Glossary

PPPoE (Point-to-Point Protocol over Ethernet) relies on two widely accepted standards:
PPP and Ethernet. PPPoE is a specification for connecting the users on an Ethernet to
the Internet through a common broadband medium, such as a single DSL line, wireless
device or cable modem. All the users over the Ethernet share a common connection, so
the Ethernet principles supporting multiple users in a LAN combine with the principles
of PPP, which apply to serial connections. From authentication, accounting and secure
access to configuration management, PPPoE supports a broad range of existing
applications and services.

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.

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.

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.

An RFC (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 final version of the RFC becomes the standard and no further comments or changes
are permitted. Change can occur, however, through subsequent RFCs.

Routing Information Protocol is an interior or intra-domain routing protocol that uses
distance-vector routing algorithms. RIP is used on the Internet and is common in the
NetWare environment as a method for exchanging routing information between
routers.

In telephony, a splitter, sometimes called a “plain old telephone service splitter" is a
device that divides a telephone signal into two or more signals, each carrying a selected
frequency range, and can also reassemble signals from multiple signal sources into a
single signal

Shielded Twisted-Pair cable consists of copper-core wires surrounded by an insulator.
Two wires are twisted together to form a pair; the pair form a balanced circuit. The
twisting prevents interference problems, STP provides protection against external
crosstalk.

A cable that wires a pin to its equivalent pin. This cable connects two dissimilar
devices, for example, a data terminal equipment (DTE) device and a data

Trivial File Transfer Protocol is an Internet file transfer protocol similar to FTP (File

Transfer Protocol), but it is scaled back in functionality so that it requires fewer
resources to run. TFTP uses the UDP (User Datagram Protocol) rather than TCP
(Transmission Control Protocol).

Two insulated wires, usually copper, twisted together and often bound into a common
sheath to form multi-pair cables. In ISDN, the cables are the basic path between a
subscriber's terminal or telephone and the PBX or the central office.

User Datagram Protocol. DP is a connectionless transport service that dispenses with
the reliability services provided by TCP. UDP gives applications a direct interface with
the Internet Protocol (IP) and the ability to address a particular application process
running on a host via a port number without setting up a connection session.

Uniform Resource Locator. URL is an object on the Internet or an intranet that resides
on a host system. Objects include directories and an assortment of file types, including
text files, graphics, video and audio. A URL is the address of an object that is normally
typed in the Address field of a Web browser. A URL is basically a pointer to the
location of an object.

By prior mutual agreement, each protocol is assigned to a specific virtual circuit, eg.,
VCI carries IP, VC2 carries IPX, etc. VC-based multiplexing may be dominant in
environments where dynamic creation of large numbers of ATM VCs is fast and
economical.

A Virtual Channel Identifier is a number that denotes a particular logical connection
between end stations (users or networks). See also, VPI.

A Virtual Path Identifier is a number that denotes a bundle of virtual channels. See also
VCI.

Virtual Private Network. These networks use public connections (such as the Internet)
to transfer information. That information is usually encrypted for security purposes.

Wide Area Networks link geographically dispersed offices in other cities or around the
globe. Just about any long-distance communication medium can serve as a WAN link
including switched and permanent telephone circuits, terrestrial radio systems and
satellite systems.

World Wide Web. Frequently used (incorrectly) when referring to "The Internet".
WWW has two major definitions. One, the whole constellation of resources that can be
accessed using Gopher, FTP, HTTP, telnet, USENET, WAIS and other tools. Two, the
universe of hypertext servers (HTTP servers).
