Preface

About Your Prestige

Congratulations on your purchase of the Prestige 782M G.SHDSL Bridge.

The Prestige is a high-performance modem for Internet/LAN access via a telephone line. Your Prestige

supports multi-protocol routing for TCP/IP and transparent bridging for other protocols.

The Prestige supports symmetrical multi-rate data transmission speeds from 72Kbps up to 2320Kbps. The

actual rate depends on the copper category of your telephone wires, distance from the central office and the

type of xDSL service you subscribe to. Its 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. See the following section for more background information on xDSL.

Register your Prestige online at www.zyxel.com for free future product updates and

information.

Your Prestige is easy to install and configure. All functions of the Prestige are software configurable via the

SMT (System Management Terminal). Advanced users may configure the Prestige using CLI (Command

Line Interface) commands.

xvi Preface

P782M G.SHDSL Bridge

What is DSL?

DSL (Digital Subscriber Line) technology 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). 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.

G.SHDSL

G.SHDSL (Single-pair High-speed Digital Subscriber Line) is a symmetrical, bi-directional DSL service that
operates on one twisted-pair wire and provides data rates up to 2.3 Mbits/sec. The “G.” in “G.SHDSL” is
defined by the G.991.2 ITU (International Telecommunication Union) state-of-the-art industry standard.

The Benefits of G.SHDSL:

• Continuous Connection

You are always online.

• Dedicated Bandwidth

• Investment Protection

• Low Maintenance

• Distance Capabilities

Line speed is “symmetric,” i.e., the same bandwidth in both directions.

Scalability. Offers a flexible upgrade path. You can choose a higher
access speed yourself - no site visit is necessary.

Connectivity requires no complex manual configuration.

G.SHDSL achieves 20% better loop-reach than older versions of
symmetric DSL. (Loop reach defines speed that can be attained at
various distances).

Getting to Know Your G.SHDSL Bridge

This chapter covers the key features and main applications of your Prestige.

The Prestige can be used for high-speed LAN-to-LAN connections or Internet access through a G.SHDSL
connection over the telephone line.

1.1 Features of the Prestige

The following features make the Prestige a complete and the flexible networking solution for most users.

High Speed Scalability

Your Prestige G.SHDSL modem supports symmetrical multi-rate data transmission speeds from 72 Kbps
up to 2312 Kbps. You can increase the capacity of the Internet connection (within certain distance
limitations) without changing your ISP or purchasing new equipment. G.SHDSL’s high symmetrical speeds
are ideal for applications like web hosting and videoconferencing as well as the two-way data traffic needs
of businesses.

Symmetrical High Speed Internet Access

The Prestige supports symmetrical transmission up to 2.3 Mbps. For NSP’s (Network Service Provider)
convenience, the Prestige also supports rate management depending on distances and service charges.

10/100MB Auto-negotiation Ethernet/Fast Ethernet Interface

This auto-negotiation feature allows the Prestige to detect the speed of incoming transmissions and adjust
appropriately, providing a faster data transfer on the Ethernet network as required. It enables fast data
transfer of either 10 Mbps or 100 Mbps in either half-duplex or full-duplex mode depending on your
Ethernet network.

The following figure shows the rear panel of your Prestige.

Figure 2-2 Prestige 782 Rear Panel and Connections

2.2.1 xDSL Port

Connect the Prestige (port labeled xDSL) to the telephone jack using the RJ-11 cable (supplied).

2.2.2 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 to the console
port of the Prestige and the other 9-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.

2-2 Hardware Installation and Initial Setup

P782M G.SHDSL Bridge

2.2.3 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 to connect your Prestige to a
computer directly or use a straight-through Ethernet cable to connect to an external hub, then 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.

2.2.4 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.

2.3 Additional Installation Requirements

• An Ethernet 10/100Base-T NIC (Network Interface Card).

• Communications software configured as follows:

 VT100 terminal emulation

 9600 baud

 parity set to none, 8 data bits, 1 stop bit

 flow control set to none

2.4 Turning On Your Prestige

At this point, you should have connected the xDSL, LAN 10/100M, console and power ports to the
appropriate devices. Make sure the power adapter is plugged into an appropriate power source and the
power switch (located on the back of your Prestige) is “on” (or pressed).

2.5 Configuring Your Prestige For Internet Access

Configure your Prestige for Internet access using:

 SMT (System Management Terminal). Access the SMT via:

o LAN or WAN using Telnet

Hardware Installation and Initial Setup

P782M G.SHDSL Bridge

o Console port using terminal emulation software

The remainder of this user’s guide shows you how to configure the Prestige for Internet access using SMT
screens. There are also some sections in this guide that also focus on using Telnet to configure the Prestige.

2.5.1 Initial Screen

When you turn on your Prestige, it performs several internal tests as well as line initialization. After the
initialization, the Prestige asks you to press [ENTER] to continue, as shown.

automatically log you out and will display a blank screen. If you see a blank screen, press [ENTER] to
display the login screen again.

Enter Password : XXXX

Figure 2-4 Login Screen

2-4 Hardware Installation and Initial Setup

P782M G.SHDSL Bridge

If, after logging on, there is no activity for longer than 5 minutes, your Prestige

will automatically log you out and display a blank screen. Press [ENTER] to bring

up the login screen again.

2.6 Resetting the Prestige

If you forget your password or cannot access the Prestige, you will need to reload the factory-default
configuration file. Uploading the configuration file replaces the current configuration file with the factory­default configuration file. This means that you will lose all configurations that you had previously and the
speed of the console port will be reset to the default of 9600bps with 8 data bit, no parity, one stop bit and
flow control set to none. The password will be reset to “1234” and the LAN IP address to 192.168.1.1also.

To obtain the default configuration file, download it from the ZyXEL FTP site, unzip it and save it in a
folder. Turn the Prestige off and then on to begin a session. When you turn on the Prestige again you will
see the initial screen. When you see the message “Press any key to enter Debug Mode within 3 seconds”
press any key to enter debug mode.

To upload the configuration file, do the following:

1. Type atlc after the Enter Debug Mode message.

2. Wait for the Starting XMODEM upload message before activating XMODEM upload on your
terminal.

3. After a successful firmware upload, type atgo to restart the Prestige.

The Prestige is now reinitialized with a default configuration file including the default password of “1234”.

2.6.1 Methods of Restoring Factory-Defaults

You can erase the current configuration and restore factory defaults by uploading the default configuration
file via the console port as described above. See later in this User’s Guide for more information on how to
transfer the configuration file to your Prestige using the SMT menus.

Use Menu 2 — WAN Setup to configure G.SHDSL settings for your WAN line. Different telephone
companies deploy different types of G.SHDSL service. If you are unsure of any of this information, please
check with your telephone company.

2.11.1 Service Type

Is your Prestige acting as a Server or Client?

1. The Prestige is a server if it is acting as a COE (Central Office Equipment).

2. The Prestige is a client if it is acting as a CPE (Customer Premise Equipment).

2.11.2 Rate Adaption

Both the Prestige and the peer must have the same transmission rate. Rate Adaption allows the Prestige to
auto-detect the peer Transfer Rate (this feature may not be available on all models).

2-10 Hardware Installation and Initial Setup

P782M G.SHDSL Bridge

2.11.3 Transfer Rates

The Prestige supports the following symmetrical multi-rate data transmission speeds:

72, 136, 200, 264, 392, 520, 776, 1032, 1160, 1544, 1736, 2056 and 2312 Kbps.

You can increase the capacity of the Internet connection (within certain limitations) without changing your
ISP or buying new equipment.

For back-to-back applications make sure that your Prestige and its peer have the same Transfer Max Rate
and the same Transfer Min Rate. Two (maximum and minimum) transfer rates are used to accommodate
fluctuations in line speed. This is known as Dynamic Bandwidth Allocation.

2.11.4 Standard Mode

If your Prestige is a server, then select the mode that applies to your region: ANSI (American National
Standards Institute) and ETSI (European Telecommunications Standards Institute). If your Prestige is a
client, select the same Standard Mode that the server side selects. ANSI and ETSI create recommendations
and standards for the telecommunications industry.

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

P782M G.SHDSL Bridge

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.

your configuration, or press [ESC] at any time to cancel.

192.168.1.1

255.255.255.0

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 Appendices 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.

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.

3-4 Internet Access

P782M G.SHDSL Bridge

3.9 Encapsulation

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

3.9.1 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.

3.9.2 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 PPP or
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 Peak Cell Rate (PCR)

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.

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. The protocol-dependent

configurations (TCP/IP and Bridging) are covered in the next chapters.

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.

4.1.1 Remote Node Profile

To configure a remote node, follow these steps:

Step 1. From the main menu, enter 11 to display Menu 11 — Remote Node Setup.

Step 2. When menu 11 appears, as shown in the following figure, type the number of the remote node

that you want to configure.

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. The extra

overhead that ENET ENCAP encapsulation entail makes them a poor choice in a LAN-to-LAN application.

Here are some examples of more suitable combinations in such an application.

Scenario 1. One VC, Multiple Protocols

PPP (RFC-2364) encapsulation with VC-based multiplexing is the best combination because no extra

protocol identifying headers are needed. The PPP 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 PPP 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

encapsulation and VC-based multiplexing.

Chapter 5

Remote Node TCP/IP Configuration

This chapter shows a sample LAN-to-LAN application and how to configure TCP/IP remote

nodes.

5.1.1 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.

Chapter 6

Filter Set Configuration

This chapter shows you how to create and apply filters.

6.1 About Filtering

Your Prestige uses filters to decide whether or not to allow passage of a data packet and/or to make a call.
There are two types of filter applications: data filtering and call filtering. Filters are subdivided into device
filters, which are discussed later.

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. Call filtering is used to determine if a
packet should be allowed to trigger a call.

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 examle, 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.

6.3 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.

Chapter 8

Firmware and Configuration File

Maintenance

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

firmware and a new configuration file.

8.1 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.

8.2 Backup Configuration

The Prestige displays different messages explaining different ways to backup,

restore and upload files in menus 24.5, 24.6, 24. 7.1 and 24.7.2; depending on

whether you use the console port or Telnet.

Option 5 from Menu 24 — System Maintenance allows you to backup the current Prestige configuration
to 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 they are faster. You
can also perform backup and restore using menu 24 through the console port. 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.

running.

8.2.5 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.

8-4 Firmware and Configuration File Maintenance

P782M G.SHDSL Bridge

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.

8.2.6 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.

8.2.7 GUI—based TFTP Clients

The following table describes some of the fields that you may see in GUI-based TFTP clients.

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.

8-12 Firmware and Configuration File Maintenance

P782M G.SHDSL Bridge

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. Put the SMT in command interpreter (CI) mode by entering 8 in Menu 24 — System

Maintenance.

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.

8.4.6 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 and “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 GUI-based TFTP clients are listed earlier in this chapter.

8.4.7 Uploading Via Console Port

FTP or TFTP are the preferred methods for uploading firmware to your Prestige. However, in the event of
your network being 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 download/upload.

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.
