Preface

About Your ADSL Bridge

Congratulations on your purchase of the Prestige 642M Series ADSL Bridge.
The Prestige 642M is an ADSL bridge used for Internet access via an ADSL line. It can run upstream
maximum rate at 640kbps and downstream rate at 8Mbps. The rate selection depends on the copper
category, distance and central side configuration. We will refer to the Prestige 642M as the P642 or simply
the Prestige from now on.
The P642's 10/100M auto-negotiating LAN interface enables fast data transfer of either 10Mbps or
100Mbps in either half-duplex or full-duplex mode depending on your Ethernet network.
Your Prestige is easy to install and configure. All functions of the Prestige are software configurable via the
SMT (System Management Terminal) Interface. PPPoE Modem firmware for your P642M will be
available by October 2000.

Prestige 642M Series ADSL Bridge

What is DSL?

DSL (Digital Subscriber Line) enhances the data capacity of the existing twisted-pair wire that runs
between the local telephone company switching offices, most homes and offices. While the wire itself can
handle higher frequencies, the telephone switching equipment is designed to cut off signals above 4,000 Hz
to filter noise off the voice line. Now, however, everybody is searching for ways to get more bandwidth to
improve access to the Web - hence DSL technologies!
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). Asymmetrical services (ADSL) are suitable for
Internet users because more information is usually downloaded than uploaded. For example, a simple
button click in a web browser can start an extended download that includes graphics and text.
As data rates increase, the carrying distance decreases. In other words, if your computer is beyond a certain
distance, from the central office of a telephone company, then you may not be able to obtain the higher
speeds. A DSL connection is a point-to-point dedicated circuit, meaning that the link is always up and that
there is no dialing required.

What is ADSL?

It is an asymmetrical technology, meaning that the downstream data rate is much higher than the upstream
data rate. As mentioned, 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.

Prestige 642M Series ADSL Bridge

Chapter 1

Getting to Know Your ADSL Bridge

This chapter describes the key features and applications of the Prestige 642M.

1.1 The Prestige 642M Series ADSL Bridge

Your Prestige integrates a high-speed 10/100Mbps LAN interface and one high-speed ADSL port into a
single package. The Prestige is ideal for high-speed Internet browsing and making LAN-to-LAN
connections to remote networks.

1.2 Features of the Prestige 642M Series

Your Prestige is packed with a number of features that give it the flexibility to provide a complete
networking solution for almost anyone.

z Ease of Installation

Your Prestige is designed for quick, intuitive and easy installation. Your Prestige weighs very little and is
extremely compact making it easy to position anywhere in your busy office.

z High Speed Internet Access

The Prestige can support downstream transmission rates of up to 8Mbps and upstream transmission rates of
832 Kbps. The Prestige also supports rate management. Rate management allows ADSL subscribers to
select an Internet access speed that best suit their needs and budget.

z 10/100Mbps Fast Ethernet LAN Interface

The Prestige's 10/100M auto-negotiating LAN interface enables fast data transfer of either 10Mbps or
100Mbps, in either half-duplex or full-duplex mode, depending on your Ethernet network.

z Protocols Supported



PPP (Point-to-Point Protocol) Bridge link layer protocol.



Transparently bridging for unsupported network layer protocols.

z Networking Compatibility

Your Prestige is compatible with the major ADSL DSLAM (Digital Subscriber Line Access Multiplexer)
providers making configuration extremely simple.

z Multiplexing

The Prestige supports VC-based and LLC-based multiplexing.

z Encapsulation

The Prestige supports PPP (RFC 2364 - PPP over ATM Adaptation Layer 5) and RFC 1483 encapsulation
over ATM.

z Full Network Management

♦ Access SMT (System Management Terminal) through a telnet connection.

Getting to Know Your ADSL Bridge 1-1

Prestige 642M Series ADSL Bridge

z PAP and CHAP Security

The Prestige supports PAP (Password Authentication Protocol) and CHAP (Challenge Handshake
Authentication Protocol). CHAP is more secure than PAP because the password is scrambled prior to
transmission. PAP, on the other hand, is readily available on more platforms.

z Filters

The Prestige has filtering functions that allow added network security and management.

1.3 Applications for the Prestige 642M

1.3.1 Internet Access

The Prestige is the ideal high-speed Internet access solution. Your Prestige supports the TCP/IP protocol,
which the Internet uses exclusively. 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.

Figure 1-1 Internet Access Application

1.3.2 LAN to LAN Application

You can use the Prestige to connect two geographically dispersed networks over the ADSL line. A typical
LAN-to-LAN application for your Prestige is shown as follows.

SYS

LAN 10M

LAN 100M

ADSL

The PWR (power) LED is on when power is applied to the Prestige.

A steady on SYS (system) LED indicates the Prestige is on and functioning
properly while an off SYS LED indicates that the system is not ready or has
malfunctioned. The system is rebooting when the SYS LED is blinking.
A steady light indicates a 10Mb Ethernet connection. The LED will blink when
data is sent/received.
A steady light indicates a 100Mb Ethernet connection. The LED will blink when
data is sent/received.
The ADSL LED is on when the Prestige is connected successfully to a DSLAM.
The LED blinks when data is sent/received. The LED is off when the link is down.

2.2 Rear Panel and Connections of the P642M

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

Figure 2-2 Rear Panel and Connections of the P642M

Hardware Installation & Initial Setup 2-1

Prestige 642M Series ADSL Bridge

Step 1.

Connect the Prestige directly to the wall jack using the included ADSL cable. Connect a microfilter(s) (see
Figure 2-4 Connecting a Microfilter) between the wall jack and your telephone(s). Microfilter(s) act as low
pass filters (voice transmission takes place in the 0 to 4KHz bandwidth). A Mircrofilter is an optional
purchase.

Step 2.

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 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 on the workstation.

Connecting the ADSL Line

Connecting a Workstation to the Prestige 10/100M LAN port

Step 3. Connecting the Power Adapter to your Prestige

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

Step 4.

For the initial configuration of your Prestige, you need to use terminal emulator software on a workstation
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 workstation. You can use an extension RS-232 cable if the enclosed
one is too short.

Connecting the Console Port

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 (Network Interface Card).
z A computer equipped with communications software (for example, Hyper Terminal in Win95)

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 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.

Step 2. Connect the side labeled “Modem” to your Prestige.
Step 3. Connect the side labeled “Line” to the telephone wall jack.

2.5 Telephone Microfilters

Telephone voice transmissions take place in the lower frequency range, 0 - 4KHz, while ADSL
transmissions take place in the higher bandwidth range, above 4KHz. A microfilter acts as a low-pass filter,
for your telephone, to ensure that ADSL transmissions do not interfere with your telephone voice
transmissions. . The purchase of a telephone microfilter is optional.

Step 1. Connect a phone cable from the wall jack to the single jack end of the Y- Connector.
Step 2. Connect a cable from the double jack end of the Y-Connector to the “wall side” of the

microfilter.

Step 3. Connect another cable from the double jack end of the Y-Connector to the Prestige.
Step 4. Connect the “phone side” of the microfilter to your telephone as shown in the following figure.

Chapter 3

Internet Access

This chapter shows you how to configure the LAN as well as the WAN

of your Prestige for Internet access

3.1 Factory Ethernet Defaults

The Ethernet parameters of the Prestige are preset in the factory with the following values:

1. IP address of 192.168.1.1 with subnet mask of 255.255.255.0 (24 bits).
These parameters should work for the majority of installations. If you wish to change the factory defaults or
to learn more about TCP/IP then please read on.

3.2 TCP/IP Parameters

3.2.1 IP Address and Subnet Mask

Just as houses on the same street share a common street name so too do computers on the same LAN share
a common network number.
Where you obtain your network number depends on your particular situation. If the ISP or your network
administrator assigns you a block of registered IP addresses, follow their instructions in selecting the IP
addresses and the subnet mask.
The subnet mask specifies the network number portion of an IP address. Your Prestige automatically
computes the subnet mask based on the IP address that you entered. You do not need to change the subnet
mask computed by the Prestige unless you are instructed to do so.

.

3.2.2 Private IP Addresses

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

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.
Note: 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.

3.4 LANs & WANs

A LAN (Local Area Network) is a computer network limited to the immediate area, usually the same
building or floor of a building. A WAN (Wide Area Network), on the other hand is an outside connection to
another network or the Internet.

3.4.1 LANs, WANs and the Prestige

The actual physical connection determines whether the Prestige ports are LAN or WAN ports. There are
two separate IP networks, one inside, the LAN network; the other outside, the WAN network as shown
next.

Figure 3-2 LAN & WAN

Internet Access 3-3

Prestige 642M Series ADSL Bridge

3.5 VPI & VCI

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
information.

3.6 Multiplexing

There are two conventions to identify what protocols the virtual circuit (VC) is carrying. Be sure to use the
multiplexing method required by your ISP.

3.6.1 VC-based multiplexing

In this case, by prior mutual agreement, each protocol is assigned to a specific virtual circuit, e.g., VC1
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.

3.6.2 LLC-based multiplexing

In this case one VC carries multiple protocols with protocol identifying information being contained in each
packet header. Despite the extra bandwidth and processing overhead, this method may be advantageous if it
is not practical to have a separate VC for each carried protocol, e.g., if charging heavily depends on the
number of simultaneous VCs.

3.7 Encapsulation

Be sure to use the encapsulation method required by your ISP. The Prestige supports the following
methods.

3.7.1 PPP

Please refer to RFC 2364 for more information on PPP over ATM Adaptation Layer 5 (AAL5). Refer to
RFC 1661 for more information on PPP.

3.7.2 RFC 1483

RFC 1483 describes two methods for Multiprotocol Encapsulation over ATM Adaptation Layer 5 (AAL5).
The first method allows multiplexing of multiple protocols over a single ATM virtual circuit (LLC-based
multiplexing) and the second method assumes that each protocol is carried over a separate ATM virtual
circuit (VC-based multiplexing). Please refer to the RFC for more detailed information.

3.8 Internet Access Configuration

Menu 4 allows you to enter the Internet Access information in one screen. Menu 4 is actually a simplified
setup for one of the remote nodes that you can access in Menu 11. Before you configure your Prestige for
Internet access, you need to collect your Internet account information from your ISP and telephone
company.

Use the following table to record your Internet Account Information. Note that if you are using PPP then
the only ISP information you need is a login name and password.

Chapter 4

Remote Node Configuration

This chapter shows you how to configure a remote node.

A remote node is required for placing calls to a remote gateway. A remote node represents both the remote
gateway and the network behind it across a WAN connection. Note that when you use Menu 4 to set up
Internet access, you are actually configuring one of the remote nodes.

4.1 Remote Node Setup

This section describes the protocol-independent parameters for a remote node.

4.1.1 Remote Node Profile

To configure a remote node, follow these steps:

Step 1. From the Main Menu, select Menu 11 – Remote Node Setup.
Step 2. When Menu 11 appears, as shown below, enter the number of the remote node that you wish to

configure.

define this remote profile. The Remote Node Profile Menu Fields table shows you how to configure the
Remote Node Menu.

4.1.2 Encapsulation & Multiplexing Scenarios

For Internet Access you should use the encapsulation and multiplexing methods used by your ISP. For a
LAN-to-LAN application, e.g., branch office and corporate headquarters, prior mutual agreement on
methods used is necessary because there is no mechanism to automatically determine
encapsulation/multiplexing. Selection of which encapsulation and multiplexing methods to use depends on

Remote Node Configuration 4-1

Prestige 642M Series ADSL Bridge

how many VCs you have and how many different network protocols you need. Here are some examples of
combinations.

Scenario 1. One VC, Multiple Protocols

PPP (RFC 2364) encapsulation with VC-based multiplexing is the best combination because the extra
protocol identifying headers that LLC-based multiplexing uses is unneeded. The PPP protocol already
contains this information.

Scenario 2. One VC, One Protocol (IP)

Select RFC-1483 encapsulation with VC-based multiplexing requires the least amount of overhead (0
octets). However, if there is a potential need for multiple protocol support in the future, it may be safer to
select PPP encapsulation instead of RFC-1483, so you don’t need to reconfigure either machine when the
time comes.

Scenario 3. Multiple VCs

If you have an equal number (or more) of VCs than the number of protocols, then select RFC-1483
encapsulation and VC-based multiplexing.

Prestige 642M Series ADSL Bridge

Chapter 5

Filter Configuration

This chapter shows you how to create and apply filter(s).

5.1 About Filtering

Your Prestige uses filters to decide whether or not to allow passage of a packet. Data filters are divided
into incoming and outgoing filters, depending on the direction of the packet relative to a port. These filters
are further subdivided into device and protocol filters, which are discussed later. The Prestige 642M
ADSL Bridge has device filters only. Device filters are applied to raw packets that appear on the wire.
They are applied at the point when the Prestige is receives and sends packets; i.e. the interface. The
interface can be an Ethernet, or any other hardware port.
The following sections describe how to configure filter sets.

The Filter Structure of the Prestige

A filter set consists of one or more filter rules. Usually, you would group related rules. The Prestige allows
you to configure up to twelve filter sets with six rules in each set, for a total of 72 filter rules in the system.
The following diagram illustrates the logic flow when executing a filter rule.

5.3 Configuring a Filter Rule

To configure a filter rule, enter its number in Menu 21.1 - Filter Rules Summary and press [Enter].
There is one type of filter rule, Device for the P642M ADSL Bridge.

5.3.1 Generic Filter Rule

This section shows you how to configure a generic filter rule.
For generic rules, the Prestige treats a packet as a byte stream. You specify the portion of the packet to
check with the Offset (from 0) and the Length fields, both in bytes. The Prestige applies the Mask (bit­wise ANDing) to the data portion before comparing the result against the Value to determine a match. The
Mask and Value are specified in hexadecimal numbers. Note that it takes two hexadecimal digits to

Filter Configuration 5-5

Prestige 642M Series ADSL Bridge

represent a byte. If the length is four, for example, then the value in either field will take 8 digits (e.g.,
FFFFFFFF).
To configure a generic rule, select Generic Filter Rule in the Filter Type field and press [Enter] to open

6.4 A Note about Filenames

The configuration file (often called the romfile or romfile-0) contains the factory default settings in the
menus such as password, DHCP Setup, TCP/IP Setup etc. It arrives from ZyXEL with a name of
P642M.rom or something similar. Once you have customized the Prestige's setting, they can be saved back
to your computer under a filename of your choosing. Choose something meaningful, e.g. “MyP642M.cfg”.
The ZyNOS firmware file (sometimes referred to as the ras file) is the file that contains the ZyXEL
Network Operating System firmware and usually is the router model name with a *.bin extension, e.g.,
P642M.bin.
With serial (Xmodem) transfer and many ftp and tftp clients (see next), the filenames on the PC are your
choice.

ftp> put P642M.bin ras
This is a sample ftp session showing the transfer of the your computer "P642M.bin" to the Prestige.

ftp> get rom-0 MyP642M.cfg
This is a sample ftp session saving the current configuration to the file MyP642M.cfg on your computer.

If your [t]ftp client does not allow you to have a destination filename different from 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, i.e., on your workstation, local
network or ftp site and so the name (but not the extension) will vary. The AT command is the command
you enter after you press “Y” when prompted in the SMT menu to go into debug mode.

6.4.1 Firmware Development

It is important to upgrade your firmware regularly, especially if there are problems. If you discover an
unexpected behavior, or bug, see if your problem is mentioned in the release notes. Load it according to
instructions (e.g., see if the default configuration file is needed also). If the problem still exists, e-mail or
call tech support.

6.5 Backup Configuration

6.5.1 Backup using the Console Port

Option 5 from Menu 24 – System Maintenance allows you to save the current Prestige configuration file
to your workstation. Backup is highly recommended once your Prestige is functioning properly.
You can perform the backup either through an FTP or TFTP client program (preferred method) or through
the RS-232 console port (in the event of the network being down). Backup via the console port under
normal conditions
should work fine; however, you must use the XMODEM protocol to perform the download/upload.

To transfer the configuration file, follow the procedure below:

System Maintenance 6-9

Prestige 642M Series ADSL Bridge

Step 1. Use telnet from your workstation 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. Put the SMT in Command Interpreter (CI) mode by entering 8 in Menu 24 – System

Maintenance.

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

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

Step 4. Launch the TFTP client on your workstation and connect to the Prestige.
Step 5. Go to SMT menu 24.5. Note that you must remain in this menu until backup is complete.
Step 6. Use the TFTP client to transfer files between the Prestige and the workstation. The file name for

the configuration file is “rom-0”.

Note that the telnet connection must be active and the SMT in CI mode before and

during the TFTP transfer.

For details on TFTP commands, please consult the documentation of your TFTP client program. For
UNIX, use “get” to transfer from the Prestige to the workstation, and “binary” to set binary transfer mode.

6.6 Restore Configuration

Option 6 from Menu 24 – System Maintenance allows you to restore the current workstation backup
configuration to your Prestige.

Step 1. Use telnet from your workstation 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. Put the SMT in Command Interpreter (CI) mode by entering 8 in Menu 24 – System

Maintenance.

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

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

Step 4. Launch the TFTP client on your workstation and connect to the Prestige.
Step 5. Go to SMT menu 24.6. Note that you must remain in this menu until file transfer is complete.
Step 6. Use the TFTP client to transfer files between the Prestige and the workstation. The remote file

name on the Prestige is “rom-0”.

Step 7. The system reboots automatically after the file transfer process is complete.

Note that the telnet connection must be active and the SMT in CI mode before and

during the TFTP transfer.

For details on TFTP commands, please consult the documentation of your TFTP client program. For
UNIX, use “put” to transfer from the workstation to the Prestige, and “binary” to set binary transfer mode.

6.7 Upload Firmware

Option 7 from Menu 24 – System Maintenance takes you to Menu 24.7 – System Maintenance –
Upload Firmware which allows you to upgrade the firmware or default configuration. You can upgrade

the firmware either through an FTP or TFTP client program (preferred method) or through the RS-232
console port (in the event of the network being down). Updating the firmware via the console port under

Uses two pairs of twisted-pair wire with a maximum distance of 100 meters between the hub and
the workstation.

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.

Address Resolution Protocol is a protocol for mapping an Internet Protocol address (IP address)
to a physical machine address that is recognized in the local network.

A high-speed line or series of connections that forms a major pathway within a network.

This is the capacity on a link usually measured in bits-per-second (bps).

Binary Digit. A single digit number in base-2 that is, in other words, either a one or a zero. A
Bit is the smallest unit of computerized data.

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

Challenge Handshake Authentication Protocol is an alternative protocol that avoids sending
passwords over the wire by using a challenge/response technique.

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.

Channel Service Unit/Data Service Unit. CSUs (channel service units) and DSUs (data service
units) are actually two separate devices that are used in conjunction with each other and often
combined into the same box. These devices are part of the hardware you need to connect
computer equipment to digital transmission lines. The Channel Service Unit device connects
with the digital communication line and provides a termination for the digital signal. The Data
Service Unit device, sometimes called a digital service unit, is the hardware component you need
to transmit digital data over the hardware channel. The device converts signals from bridges,
routers and multiplexors into bipolar digital signals used by digital lines. Multiplexors mix voice
signals and data on the same line.

Data Communications Equipment is typically a modem or other type of (data) communication
device. The DCE sits between the DTE (data terminal equipment) and a transmission circuit
such as a phone line.

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 System links names to IP addresses. When you access Web sites on the Internet
you can type the IP address of the site or the DNS name. When you type a domain name in a
Web browser a query is sent to the primary DNS server defined in your Web browser’s
configuration dialog box. The DNS server converts the name you specified to an IP address and
returns this address to your system. Thereafter, the IP address is used in all subsequent
communications.

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.

Dynamic RAM (Random Access Memory) stores information in capacitors that must be
refreshed periodically.

Digital Subscriber Line technologies enhances 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.

Originally, the DTE (data terminal equipment) was a dumb terminal or printer, but today it is a
computer, bridge or router that interconnects local area networks.

ElectroMagnetic Interference. Interference by electromagnetic signals that can cause reduced
data integrity and increased error rates on transmission channels.

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.

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.

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.

technique is vulnerable to wiretapping (eavesdropping) because the password can be captured
and used by someone to log onto the system.

Prestige Network Commander. A Windows-based setup wizard for some Prestige routers.

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.

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.

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 the
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 NetWare, the SAP (Service Advertising Protocol) broadcasts information about available
services on the network that other network devices can listen to. A server sends out SAP
messages every 60 seconds. A server also sends out SAP messages to inform other devices that
it is closing down. Workstations use SAP to find services they need on the network.

A computer, or a software package, that provides a specific kind of service to client software
running on other computers.

System Network Management Protocol is a popular management protocol defined by the
Internet community for TCP/IP networks. It is a communication protocol for collecting
information from devices on the network.

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) and a data communications equipment (DCE) device.
A straight through Ethernet cable is the most common cable used.

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.

A device that allows you to send commands to a computer somewhere else. At a minimum, this
usually means a keyboard and a display screen and some simple circuitry.

Software that pretends to be (emulates) a physical terminal and allows you to type commands to
a computer somewhere else.

TFTP

UDP

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).

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 IP and the
ability to address a particular application process running on a host via a port number without
setting up a connection session.

WWW

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.

A Virtual Channel Identifier identifies virtual channels between users or between users and
networks.

A Virtual Path Identifier identifies virtual paths between users or between users and networks.

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).

VPI & VCI

This appendix describes VPI and VCI.

VPI & 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 VC (virtual channel) Logical connections between end stations
z VP (virtual path) A bundle of VCs

Think of a VP 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.
