Preface xiii
Prestige 650M-17 ADSL Modem
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 and most homes and offices. While the wire itself
can handle higher frequencies, the telephone switching equipment is designed to cut off signals above 4,000
Hz to filter noise off the voice line, but now 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. 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.
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?
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, for example, 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. What are
the advantages of ADSL from the point of view of the Network Service Provider (NSP) and the end user?

The following figure shows the rear panel and connections of your Prestige.
Figure 2-2 Prestige Rear Panel and Connections
2.2.1 DSL Port
Connect the Prestige directly to the wall jack using the included ADSL cable (with RJ-45 connectors) Make
sure you connect an ISDN splitter between the wall jack and your telephone(s) and computer(s).
2.2.2 LAN 10/100M 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 or a straight-through Ethernet cable

Prestige 650M-17 ADSL Modem
to connect your Prestige to a computer or an external hub. If the Prestige is connected directly to a hub,
connect one end of the straight-through cable from the hub to the NIC on the computer.
When the Prestige is on and properly connected to a computer or a hub, the
corresponding LAN LED on the front panel turns on.
2.2.3 Power Port
Connect the power adapter to the port labeled POWER on the rear panel of your Prestige.
To avoid damage to the Prestige, make sure you use the correct power adapter.
Refer to the Power Adapter Specification Appendix for this information.
2.2.4 Reset Button
Refer to section 2.7 for information on the RESET button.
2.3 Additional Installation Requirements
A computer with an Ethernet 10Base-T/100Base-T NIC (Network Interface Card).
After the Prestige has been successfully connected to your network, you can make future changes to the
configuration via Telnet.
2.4 Connecting an ISDN Splitter
This device keeps the ISDN and ADSL signals separated, giving them the capability to provide
simultaneous Internet access and ISDN service on the same line. Splitters also eliminate the destructive
interference conditions caused by telephone sets. The purchase of an ISDN splitter is optional.
Noise generated from a telephone in the same frequency range as the ADSL signal, can disrupt 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. When an ISDN splitter is installed at the entry point, where the line comes into the home,
it will filter the ISDN signals before combining the ADSL and ISDN signals transmitted and received. The
issues of noise and impedance are eliminated with a single ISDN splitter installation.
An ISDN splitter is easy to install as shown in the following figure.

Chapter 3
Internet Access
This chapter shows you how to configure the LAN and 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:
♦ IP address of 192.168.1.1 with subnet mask of 255.255.255.0 (24 bits).
3.2 LANs and 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.
3.2.1 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 3-1 LAN & WAN IPs
Internet Access 3-1
Prestige 650M-17 ADSL Modem
3.3 TCP/IP Parameters
3.3.1 IP Address and Subnet Mask
Like houses on a street that share a common street name, the computers on a LAN share one 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.
If the ISP did not explicitly give you an IP network number, then most likely you 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. The Internet Assigned Number
Authority (IANA) reserved this block of addresses specifically for private use; please do not use any other
number unless you are told otherwise. Let’s say you select 192.168.1.0 as the network number; which
covers 254 individual addresses, from 192.168.1.1 to 192.168.1.254 (zero and 255 are reserved). In other
words, the first three numbers specify the network number while the last number identifies an individual
computer on that network.
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 Ethernet Setup
This section describes how to configure the Ethernet using Menu 3-Ethernet Setup. From the main menu,
enter 3 to display menu 3. Settings configured in Menu 3-Ethernet Setup apply to the LAN side of the
modem only, please read the Filter Set Configuration chapter first, then return to this menu to define the
filter sets.
3.5 Protocol Dependent Ethernet Setup
Depending on the protocols for your applications, you need to configure the respective Ethernet setup, as
outlined next.

3.7 VPI and VCI
Be sure to use the correct Virtual Path Identifier (VPI) and Virtual Channel Identifier (VCI) numbers
supplied by your telephone company. The valid range for the VPI is 0 to 255 and for the VCI is 32 to
65535 (0 to 31 is reserved for local management of ATM traffic). Please see the appendix on Virtual Circuit Topology for more information.
3.8 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.
3.8.1 VC–based Multiplexing
In this case, by prior mutual agreement, each protocol is assigned to a specific virtual circuit, for example,
VC1 carries IP, etc. VC-based multiplexing may be dominant in environments where dynamic creation of
large numbers of ATM VCs is fast and economical.
Internet Access 3-3
Prestige 650M-17 ADSL Modem
3.8.2 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, for example, if charging heavily depends on
the number of simultaneous VCs.
3.9 Encapsulation
Be sure to use the encapsulation method required by your ISP. The Prestige supports the following
methods.
3.9.1 PPPoA
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.
3.9.2 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.
3.10 IP Address Assignment
A static IP is a fixed IP that your ISP gives you. A dynamic IP is not fixed; the ISP assigns you a different
one each time.
3.11 Internet Access Configuration
Menu 4 allows you to enter your 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 PPPoA
encapsulation the only ISP information you need is a login name and password. If you are using RFC 1483,
you do not need a login name or password.

3.11.1 Traffic Shaping
Traffic Shaping is an agreement between the carrier and the subscriber to regulate the average rate and
“burstiness” or fluctuation of data transmission over an ATM network. This agreement helps eliminate
congestion, which is important for transmission of real time data such as audio and video connections.
Peak Cell Rate (PCR) is the maximum rate at which the sender can send cells. This parameter may be lower
(but not higher) than the maximum line speed. 1 ATM cell is 53 bytes (424 bits), so a maximum speed of
832 Kbps gives a maximum PCR of 1962 cells/sec. This rate is not guaranteed because it is dependent on
the line speed.
Sustained Cell Rate (SCR) is the mean cell rate of a bursty, on-off traffic source that can be sent at the peak
rate, and a parameter for burst-type traffic.SCR may not be greater than the PCR; the system default is 0
cells/sec.
Maximum Burst Size (MBS) is the maximum number of cells that can be sent at the PCR. After MBS is
reached, cell rates fall below SCR until cell rate averages to the SCR again. At this time, more cells (up to
the MBS) can be sent at the PCR again.
If the PCR, SCR or MBS is set to the default of “0”, the system will assign a
maximum value that correlates to your upstream line rate.
The following figure illustrates the relationship between PCR, SCR and MBS.

Prestige 650M-17 ADSL Modem

If the PCR is set to the default of “0”, the system will assign a maximum value
that correlates to your upstream line rate.

Remote Node Configuration
This chapter covers the parameters that are protocol-independent.
4.1 Remote Node Setup
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. When you use menu 4 to set up Internet
access, you are configuring one of the remote nodes.
This section describes the protocol-independent parameters for a remote node.

4.1.2 Encapsulation and Multiplexing Scenarios
For Internet access you should use the encapsulation and multiplexing methods used by your ISP. For
LAN-to-LAN applications, e.g., branch office and corporate headquarters, prior agreement on methods is
necessary because encapsulation and multiplexing cannot be automatically determined. Which methods to
use depends on how many VCs you have and how many different network protocols you need. Here are
some examples of more suitable combinations in such an application.
Scenario 1. One VC, Multiple Protocols
PPPoA (RFC-2364) encapsulation with VC-based multiplexing is the best combination because no extra
protocol identifying headers are needed. The PPPoA protocol already contains this information.
Scenario 2. One VC, One Protocol (IP)
Selecting 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 PPPoA encapsulation instead of RFC 1483, so you do not need to reconfigure either computer later.
Scenario 3. Multiple VCs
If you have an equal number (or more) of VCs than the number of protocols, then select RFC 1483

4.1.3 Outgoing Authentication Protocol
For obvious reasons, you should employ the strongest authentication protocol possible. However, some
vendors’ implementation includes specific authentication protocol in the user profile. It will disconnect if
the negotiated protocol is different from that in the user profile, even when the negotiated protocol is
stronger than specified. If the peer disconnects right after a successful authentication, make sure that you
specify the correct authentication protocol when connecting to such an implementation.

Chapter 5
Filter Set Configuration
This chapter shows you how to create and apply filters.
5.1 About Filtering
Your Prestige uses filters to decide whether or not to allow passage of data packets. Data filtering examines
the data to determine if the packet should be allowed to pass. Data filters are divided into incoming and
outgoing filters, depending on the direction of the packet relative to a port. Data filtering can be applied on
either the WAN side or the Ethernet side.
Outgoing packets undergo data filtering before they encounter call filtering. Call filters are divided into two
groups, the built-in call filters and user-defined call filters. Your Prestige has built-in call filters that prevent
administrative, for example, RIP packets from triggering calls. These filters are always enabled and not
accessible to you. Your Prestige applies the built-in filters first and then the user-defined call filters, if
applicable, as illustrated in the figure shown next.

5.3 Generic Filter Rule
The purpose of generic rules is to allow you to filter non-IP packets. For generic rules, the Prestige treats a
packet as a byte stream as opposed to an IP packet. 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 (bit-wise 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.
Two hexadecimal digits represent a byte, so if the length is 4, the value in either field will take 8 digits, e.g.,
FFFFFFFF.

This chapter shows you how to back up and restore your configuration file as well as upload new
firmware and a new configuration file.
7.1 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
network or FTP site and so the name (but not the extension) may vary. After uploading new firmware, see
the ZyNOS F/W Version field in Menu 24.2.1 – System Maintenance – Information to confirm that you
have uploaded the correct firmware version. The AT command is the command you enter after you press
“y” when prompted in the SMT menu to go into debug mode.

Enter 5 from Menu 24 - System Maintenance to backup the current Prestige configuration on your
computer. Backup is highly recommended once your Prestige is functioning properly. FTP is the preferred
methods for backing up your current configuration to your computer since it is fastest. 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.
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.

follow the procedure shown next.
7-4 Firmware and Configuration File Maintenance
Prestige 650M-17 ADSL Modem
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. 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 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 SMT 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.
7.2.6 TFTP Command Example

Virtual Circuit Topology
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:
• Virtual Channel Logical connections between ATM switches
• Virtual Path A bundle of virtual channels
• Virtual Circuit A series of virtual paths between circuit end points
Diagram 2 Virtual Circuit Topology
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; a VCI (Virtual Channel Identifier) identifies a
channel within a virtual path.
The VPI and VCI identify a virtual path, that is, termination points between ATM switches. A series of
virtual paths make up a virtual circuit.
Your service provider should supply you with VPI/VCI numbers.
