What is DSL? xiii

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.

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.

Prestige 642 PPPoE Modem

Hardware Installation & Initial Setup 2-3

2.2.4 Connecting the Console Port

For the initial configuration of your Prestige, you need to use terminal emulator software on a computer and

connect it to the Prestige through the console port. Connect the 9-pin end of the console cable (9-pin to 25-

pin console cable supplied) to the console port of the Prestige and the 25-pin end to a serial port (COM1,

COM2 or other COM port) of your computer. You can use an extension RS-232 cable if the enclosed one is

too short.

2.3 Additional Installation Requirements

In addition to the contents of your package, there are other hardware and software requirements you need

before you can install and use your Prestige. These requirements include:

z A computer with Ethernet 10Base-T/100Base-T NIC.

z A computer equipped with communications software (for example, Hyper Terminal in Win98)

configured to the following parameters:

¾ VT100 terminal emulation.

¾ 9600 Baud rate.

¾ No parity, 8 Data bits, 1 Stop bit.

¾ Flow Control set to None

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.

Prestige 642 PPPoE Modem

2-4 Hardware Installation & Initial Setup

Figure 2-3 Connecting a POTS Splitter

Step 1. Connect the side labeled “Phone” to your telephone.

Step 2. Connect the side labeled “Modem” to your Prestige.

Step 3. Connect the side labeled “Line” to the telephone wall jack.

2.5 Default Settings

Your Prestige is shipped with the following default settings:

¾ VPI: 8, VCI: 35

¾ WAN interface: PPPoE LLC mode

¾ Console port speed: 9600 bps

¾ DHCP: Server

¾ Password: “1234”

Depending on your region, the default password and VPI/VCI may differ.

2.6 Turning On the Prestige

At this point, you should have connected the console port, the ADSL line, the Ethernet port and the power

port to the appropriate devices or lines. Execute the terminal emulation program if you plan to configure the

Prestige with the Command Line Interface. Turn the power switch (located on the back of your Prestige)

from OFF to ON to turn on your Prestige.

• Proceed to the Web Configurator chapter if you want to configure the Prestige using the web

configurator. This is the most user-friendly configuration method.

• Proceed to the Command Line Interface chapter if you want to configure the Prestige using

the Command Line Interface.

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

Prestige 642 PPPoE Modem

Web Configurator 3-5

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

to 31 is reserved for local management of ATM traffic). Please see the VPI & VCI Appendix for more

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

Prestige 642 PPPoE Modem

3-12 Web Configurator

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.

FIELD LABEL FIELD DESCRIPTION

DHCP

DHCP If set to Server, your Prestige can assign IP addresses, an IP default gateway and

DNS servers to Windows and other systems that support the DHCP client. If set to

None, the DHCP server will be disabled. If set to Relay, the Prestige acts as a

surrogate DHCP server and relays DHCP requests and responses between the

remote server and clients. Enter the IP address of the actual, remote DHCP server

in the Remote DHCP Server field in this case. When DHCP is used, the following

items need to be set:

Client IP Pool

Starting Address

This field specifies the first of the contiguous addresses in the IP address pool.

Size of Client IP Pool This field specifies the size or count of the IP address pool.

Primary DNS Server Enter the IP addresses of the DNS servers. The DNS servers are passed to the

DHCP clients along with the IP address and the subnet mask.

Secondary DNS Server As above.

Remote DHCP Server If Relay is selected in the DHCP field above then enter the IP address of the

actual remote DHCP server here.

TCP/IP

IP Address Enter the IP address of your Prestige in dotted decimal notation, for example,

192.168.1.1 (factory default).

IP Subnet Mask Your Prestige will automatically calculate the subnet mask based on the IP

address that you assign. Unless you are implementing subnetting, use the subnet

mask computed by the Prestige.

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

Prestige 642 PPPoE Modem

Web Configurator 3-15

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]

P642ME-13>

Command Line Interface 4-3

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.

Firmware and Configuration File Maintenance 5-1

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.

Prestige 642 PPPoE Modem

5-2 Firmware and Configuration File Maintenance

Table 5-1 Filename Conventions

FILE TYPE INTERNAL

DESCRIPTION

Configuration

File

Rom-0 *.rom This is the configuration filename on the

Prestige. Uploading the rom-0 file replaces

the entire ROM file system, including your

Prestige configurations, system-related data

(including the default password), the error log

and the trace log.

Firmware Ras *.bin This is the generic name for the ZyNOS

firmware on the Prestige.

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.

Prestige 642 PPPoE Modem

Firmware and Configuration File Maintenance 5-3

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.

5-4 Firmware and Configuration File Maintenance

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.

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.

5.3.1 Restore Using FTP or TFTP

5-10 Firmware and Configuration File Maintenance

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.

Figure 5-8 Example Xmodem Upload

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

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

Appendix A VPI and VCI A

Appendix A

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.

BGlossary

Glossary

100Base-T Uses two pairs of twisted-pair wire with a maximum distance of 100 meters between

the hub and the workstation.

10Base-T The 10-Mbps baseband Ethernet specification that uses two pairs of twisted-pair

cabling (Category 3 or 5), one pair for transmitting data and the other for receiving

data.

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.

Analog An electrical circuit that is represented by means of continuous, variable physical

quantities (such as voltages and frequencies), as opposed to discrete representations

(like the 0/1, off/on representation of digital circuits).

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.

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.

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

Camping Out Staying in a "safe" place once a hacker has broken into a system. The term can be used

with a physical location, electronic reference or an entry point for future attacks.

CHAP Challenge Handshake Authentication Protocol is an alternative protocol that avoids

sending passwords over the wire by using a challenge/response technique.

Client A software program that is used to contact and obtain data from a server software

program on another computer. Each client program is designed to work with one or

more specific kinds of Server programs and each server requires a specific kind of

client. A web browser, for example, is a specific kind of client.

CO Central Office. A CO is a facility that serves local telephone subscribers. In the CO,

subscribers' lines are joined to switching equipment that allows them to connect to each

other for both local and long distance calls.

COE Central Office Equipment. COE is where home and office phone lines terminate and

connect to a much larger switching system.

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

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

Prestige 642 PPPoE Modem

Glossary C

Interface 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.

CPE Customer Premise Equipment. CPE is privately-owned telecommunication equipment

at an organization’s site that is attached to the telecommunication network. CPE

includes routers, modems, PBXs, telephones, key systems, facsimile products, voice

processing equipment and video communication equipment.

Crossover

Ethernet Cable

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

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

data communications equipment (DCE) devices.

DHCP Dynamic Host Configuration Protocol automatically assigns IP addresses to clients

when they log on. DHCP centralizes IP address management on central computers that

run the DHCP server program. DHCP leases addresses, for a period of time, which

means that past addresses are “recycled” and made available for future reassignment to

other systems.

Domain Name The unique name that identifies an Internet site. Domain Names always have two or

more parts that are separated by dots. The part on the left is the most specific and the

part on the right is the most general.

DRAM Dynamic RAM (Random Access Memory) stores information in capacitors that must

be refreshed periodically.

DSL 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.

DSLAM 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.

Embedded Web This is an HTML-based configurator that usually includes an Internet Access Wizard

Ethernet A very common method of networking computers in a LAN. There are a number of

adaptations to the IEEE 802.3 Ethernet standard, including adaptations with data rates

of 10 Mbits/sec and 100 Mbits/sec over coaxial cable, twisted-pair cable and fiber-optic

cable. The latest version of Ethernet, Gigabit Ethernet, has a data rate of 1 Gbit/sec.

FAQ Frequently Asked Questions. FAQs are documents that list and answer the most

common questions on a particular subject.

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

electromagnetic spectrum and thus the bandwidth of various communication systems.

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.

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 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

site.

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.

IP Internet Protocol. (Currently IP version 4 or IPv4). The underlying protocol for

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

IPCP (PPP) IP Control Protocol allows changes to IP parameters such as the IP address.

ISP Internet Service Providers provide connections into the Internet for home users and

businesses. There are local, regional, national, and global ISPs. You can think of local

ISPs as the gatekeepers into the Internet.

LAN Local Area Network is a shared communication system to which many computers are

attached. A LAN, as its name implies, is limited to a local area. This has to do more

with the electrical characteristics of the medium than the fact that many early LANs

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.

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

status of specific MI1951 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.

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 of 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 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.

Multiplexor 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.

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.

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

resources, you have a computer network. Connect two or more networks together and

you have an internet.

NIC Network Interface Card. A board that provides network communication capabilities to

and from a computer system. Also called an adapter.

Node Any single computer connected to a network.

PAP Password Authentication Protocol is a security protocol that requires users to enter a

password before accessing a secure system. The user’s name and password are sent

over the wire to a server where they are compared with a database of user account

Prestige 642 PPPoE Modem

FGlossary

names and passwords. This technique is vulnerable to wiretapping (eavesdropping)

because the password can be captured and used by someone to log onto the system.

POP Post Office Protocol. This is a common protocol used for sending, receiving, and

delivering mail messages.

Port 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.

Port (H/W) 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.

POTS 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.

PPP 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 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.

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.

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

Prestige 642 PPPoE Modem

Glossary G

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.

RFC 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.

RIP 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.

Splitter 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

STP 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.

Straight-through

Ethernet cable

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

communications equipment (DCE) device. A straight through Ethernet cable is the

most commonly used Ethernet cable.

SUA Single User Account. Your system’s SUA feature allows multiple user Internet access

for the cost of a single ISP account. See also NAT.

TCP Transmission Control Protocol is a connection-oriented transport service that ensures

the reliability of message delivery. It verifies that messages and data were received.

Telnet Telnet is the login and terminal emulation protocol common on the Internet and in

UNIX environments. It operates over TCP/IP networks. Its primary function is to allow

users to log into remote host systems.

Terminal A device that allows you to send commands to a computer somewhere else. At a

minimum, this usually means a keyboard, display screen and some simple circuitry.

Terminal Software that pretends to be (emulates) a physical terminal and allows you to type

Prestige 642 PPPoE Modem

HGlossary

Software commands to a computer somewhere else.

TFTP 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).

Twisted Pair 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.

UDP 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.

URL 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.

VC-based

Multiplexing

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.

VCI A Virtual Channel Identifier is a number that denotes a particular logical connection

between end stations (users or networks). See also, VPI.

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

VCI.

VPN Virtual Private Network. These networks use public connections (such as the Internet)

to transfer information. That information is usually encrypted for security purposes.

WAN 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.

WWW 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).

xDSL Digital Subscriber Line(s) where x, when specified, denotes a particular flavor of DSL,

eg., ADSL, G.SHDSL, SDSL, VDSL, RDSL, etc.
