1 Introduction

Congratulations on your purchase of the ZyXEL Prestige 2864I
Remote Access Router. The Prestige is the first device to integrate a
Router and Bridge into a single package. In a modem-sized box, the
Prestige offers inexpensive yet complete telecommunications and
internetworking solutions for your home or branch office. The Prestige
is ideal for everything from Internet browsing to receiving calls from
Remote Dial-in Users to making LAN-to-LAN connections to Remote
Nodes.

Distinguishing features of the Prestige include support for a full range of
networking protocols such as TCP/IP (Transmission Control
Protocol/Internet Protocol), Novell IPX (Internet Packet Exchange),
and Transparent Bridging. The complete solution also includes Remote
Dial -in User support, an Internet Single User Account (Network
Address Translation), POTS line support (Plain Old Telephone Service;
also called A/B Adapter in Europe), extensive Network Management,
and solid security features.

Features

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

Ease of Installation

The Prestige is a self-contained unit that is quick and easy to install.
Physically, it resembles an external modem except for the fact that it is a
router and uses an Ethernet cable to connect to the host network.

Introduction 1

ISDN Basic Rate Interface (BRI)

Using either a standard S/T or U Interface the Prestige supports a full
range of switch types. The switch type depends on the CO (Central
Office) switch your ISDN line is connected to. See Chapter 16 for
more information on North American, European, and Asian ISDN
firmware and switch types supported by the Prestige.

The two B-channels can be used independently for two destinations. Or
they can be bundled for one connection to support bandwidth-on­demand.

Built-in V.34 Modem

The Prestige has a built-in V.34 modem. This enables it to communicate
to remote routers or users at speeds up to 28.8Kbps through the ISDN
connection.

Multiple Networking Protocol Support

The Prestige is a multi-protocol router. It supports TCP/IP, Novell
IPX, and Transparent Bridging.

2 Introduction

Standard Phone Jack

The Prestige is equipped with a standard phone jack for connection to a
telephone, FAX machine, or modem.

Dial On Demand

The Dial On Demand feature allows the Prestige to automatically place
a call to a Remote Node whenever there is traffic coming from any
workstation on the LAN to that remote site.

Bandwidth On Demand

The Prestige supports bandwidth up to 128Kbps over a single ISDN
BRI line. It incorporates PPP/MP (Point-to-Point Protocol/Multilink
Protocol ) to bundle two B channels over a BRI line. In addition, the
Prestige dynamically allocates bandwidth between the two B channels,
increasing or decreasing speeds as needed to allow for greater
efficiency in data transfer. It supports BAP (Bandwidth Allocation
Protocol ) and BACP (Bandwidth Allocation Control Protocol) to
manage the number of links in multilink bundle.

Full Network Management

The Prestige incorporates SNMP (Simple Network Management
Protocol ) support and menu-driven network management via an RS­232 or Telnet connection. The Prestige is also equipped with a Call
Detail Record (CDR) to help analyze and manage your telephone bill.

RADIUS (Remote Authentication Dial In User
Service)

The RADIUS feature allows you to use an external, central, Unix based
server to support thousands of users.

PPP Security

The Prestige supports PAP (Password Authentication Protocol) and
CHAP (Challenge Handshake Authentication Protocol).

DHCP Support (Dynamic Host Configuration
Protocol)

DHCP (Dynamic Host Configuration Protocol) allows you to
dynamically and automatically assign IP address settings to hosts on
your network.

Introduction 3

Call Control

The Prestige provides budget management for outgoing calls and
maintains a blacklist for unreachable phone numbers in order to save
you the expense of unnecessary charges.

Data Compression

The Prestige incorporates Stac data compression and CCP
(Compression Control Protocol).

Networking Compatibility

The Prestige is compatible with remote access products from other
companies such as Ascend, Cisco, and 3Com. Furthermore, it supports
Microsoft Windows 95 and Windows NT remote access capability.

Applications For Your Prestige

Some applications for the Prestige include:

Internet Access

4 Introduction

The Prestige supports the TCP/IP protocol, which is the language used
for the Internet. It is also compatible with access servers manufactured
by major vendors such as Cisco and Ascend.

Internet Single User Account (SUA)

For a small office environment, the Prestige offers a Single User Internet
Account from an ISP (Internet Service Provider). This allows multiple
users on the LAN (Local Area Network) to access the Internet
concurrently for the cost of a single user.

Single User Account address mapping can also be used for LAN to
LAN connection.

Multiprotocol LAN-to-LAN Connection

The Prestige can dial to or answer calls from another remote access
router connected to a different network. The Prestige supports TCP/IP,
Novell IPX, and has the capability to bridge any Ethernet protocol.

Telecommuting Server

The Prestige allows Remote Dial-in Users to dial-in and gain access to
your LAN. This feature enables users that have workstations with
remote access capabilities, e.g., Windows 95, to dial in using an ISDN
terminal adapter (TA) to access the network resources without
physically being in the office.

Mobile Users with V.34 Modems

The Prestige has a built-in V.34 modem. This allows mobile users that
have workstations with remote access capabilities to dial-in to the
Prestige using a standard V.34 modem to access network resources.

long waits common when ordering a new line. Use the information in
this section to place the order (see Chapter 16 for information on
provisioning your ISDN line). If you have already installed your ISDN
line, you can check the following section to make sure that you can use
all the features of your Prestige.

1. Contact your local telephone company’s ISDN Ordering Center.

2. Find out what type of ISDN service is available. Refer to Chapter
16 to find out the provisioning information for the appropriate
switch type and ISDN service. For the U.S., the Prestige (both U
and S/T Interface) have been approved by Bellcore and have IOC
(ISDN Ordering Code) “S” Capability, EZ-ISDN 1.

3. Provide your telephone company with the proper provisioning
information.

4. When the telephone company installs your ISDN line, be sure to
obtain the following information:

• ISDN switch type.

• ISDN telephone number(s).

• ISDN Service Profile Identifiers (SPID) number(s) (only for

North America).

Collecting General Setup Information

The Prestige requires the following system information. You can obtain
all the pertinent information from your network administrator. Record
this information into the worksheet as it becomes available. This
worksheet will later be referred to as you configure your Prestige.

• System Name - This is the name given to the Prestige for
identification purposes. This name should be no more than 8
alphanumeric characters. Spaces are not allowed, but “-” and “_”
are accepted. This name can be obtained remotely via the SNMP

management protocol and will be displayed as the prompt when the
user enters the Command Mode.

• Route IP Field - For Internet access, you will need to enable the
Route IP Field. See Chapter 4 for more details on configuring your
Prestige for Internet access. To support Novell IPX, or Bridging,
enable the appropriate protocol and reference the related chapters
for detailed information.

You have now collected all of the general setup information you need.
Make sure that you have entered all the values onto the worksheet
before proceeding to the next section.

Collecting ISDN Phone Line Information

After you have successfully installed the ISDN phone line or if you
already have one installed, you need to use the ISDN line information to
complete the worksheet and configure your Prestige. Your telephone
company can give you the following information to configure the
Prestige:

Switch Type Geography No of Phone #s No of SPIDs

AT&T 5ESS NI-1 North America 2 2
AT&T 5ESS Point to Point North America 1 0
AT&T 5ESS Multipoint North America 2 2
Northern Telecom NI-1 North America 2 2
Northern Telecom Custom North America 2 2
DSS1 Europe, Asia 2 N/A

company. Check with your telephone company and choose the
appropriate option on the worksheet. For North America, select
your ISDN switch type. For DSS1 and 1TR6, verify this field to
make sure that you have the proper firmware loaded.

• B Channel Usage - Determine which connection is appropriate for
your B channel and check the corresponding option on the
worksheet.

If your Prestige is the only device using the ISDN line, then

configure B Channel Usage to Switch/Switch so that your device
will use both B channels to communicate. If your Prestige is sharing
the ISDN line with other devices, then configure B Channel Usage
to Switch/Unused.

• Telephone Number(s) - Record on the worksheet the telephone
number(s) given to you by your ISDN provider. Some switch types
only have one telephone number. These phone numbers should be
in a standard digit format (for example, 5551212). Note that these
fields will only accept digits, so - and spaces will not be accepted.

• Analog Call - Check the appropriate Analog Call option on the
worksheet for each telephone number. This information is later used
to configure the Prestige in routing an incoming analog call. Set to
modem, A/B adapter, or select Ignore if you don’t want to utilize
this option.

• SPID Number(s) - (For North America only) The SPID (Service
Profile Identifier) is a number used by a central office switch for
identification purposes. With the switch information, see the
previous table for the number of SPIDs you must enter.

You have now collected all of the necessary information about your
ISDN phone line. Make sure that these values are entered into your
worksheet before you continue to the next section. For DSS1 and
1TR6 ISDN, refer to Chapter 3.

Before You Begin 13

Collecting Ethernet Setup Information

This section assumes that you are setting up your Prestige for a TCP/IP
connection. If you want to configure the Prestige for other protocols
(e.g., IPX), refer to the appropriate chapters.

• Ethernet Interface - The first step is to determine the type of
Ethernet interface you will be using on the Prestige. There are two
options: AUI or UTP. Record the interface type onto the
worksheet. If you have a 10Base2 (BNC), you should choose
AUI.

• IP Address - An IP Address is required for TCP/IP protocol. The
IP Address is the unique 32-bit number assigned to your Prestige.
This address is written in dotted decimal notation (four 8-bit
numbers, between 0 and 255, separated by periods), e.g.,

192.68.203.5.

Record the IP Address into the worksheet as assigned by your

network administrator. Note that every machine on an internet must
have a unique IP address - do not assign an arbitrary address to
any machine.

• IP Sub-net Mask - This field is required for TCP/IP protocol. An

The table below lists some examples of IP subnet masks and the
number of hosts that are allowed. Consult your network administrator if
you are unsure of this value.

14 Before You Begin

IP address consists of two parts, the network ID and the host ID.
The IP Subnet Mask is used to specify the network ID portion of
the address, expressed in dotted decimal notation. The Prestige will
automatically calculate this mask based on the IP address that you
assign. Unless you have special need for subnetting, use the default
mask as calculated by the Prestige.

IP Subnet Mask Number of Host IDs Number of Bits
