1.3 Features of Prestige 128MH

Your 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

Your Prestige 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.

Multiple WAN Ports

Your Prestige 128MH has three WAN ports (WAN-1,2,3). WAN port 1 can be connected to a dial­up/leased line modem or to an ISDN TA (Terminal Adapter). WAN port 2,3 are internally
connected to two high-speed 56K modems that support dial-up configurations.

Leased Line/Dial Back-Up Support

Your Prestige 128MH supports a leased line connection to its serial port WAN port 1. The
Prestige can also support dial back-up function for the leased line connection.

Multiple Networking Protocol Support

The Prestige 128MH is a multi-protocol router that supports TCP/IP, Novell IPX, and Transparent
Bridging.

Dial-On-Demand

The Dial-On-Demand feature allows the Prestige 128MH to automatically place a call to a remote
node whenever there the traffic coming from any workstation on the LAN is directed to that
particular remote site.

Bandwidth-On-Demand

The Bandwidth-On-Demand feature provides flexible bandwidth when needed. The Prestige
128MH dynamically allocates bandwidth between the WAN ports, increasing or decreasing

speeds as needed to allow for greater efficiency in data transfer.

1-5

Prestige 128MH PSTN Router/Hub

Chapter 1 Getting to Know Your Router/Hub

By using the PPP/MP (Point-to-Point Protocol/Multilink Protocol), your Prestige 128MH can
bundle three WAN ports connected to three different internal and external modems in order to use
the maximum available bandwidth. The Prestige 128MH supports BAP (Bandwidth Allocation
Protocol) and BACP (Bandwidth Allocation Control Protocol) to manage the number of links in
multilink bundle.

Full Network Management

Your Prestige 128MH supports SNMP (Simple Network Management Protocol) and allows
menu-driven network management via an RS-232 or Telnet connection. Your Prestige is also
equipped with a Call Detail Record to help analyze and manage your telephone bill.

RADIUS

The RADIUS (Remote Authentication Dial-In User Service) feature allows you to use an external
and central Unix-based server to support thousands of users.

PAP and CHAP Security

The Prestige supports PAP (Password Authentication Protocol) and CHAP (Challenge Handshake
Authentication Protocol). With PAP authentication enabled, the user sends the name and password
in plain text. Generally, CHAP authentication is more secure since the password is scrambled
prior to transmission. However, PAP is readily available on more platforms.

DHCP Support

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

Call Control

Your 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.

Chapter 2 Hardware Installation & Initial Setup

This section outlines how to connect your Prestige 128MH to the LAN and the WANs. Refer to
Figure 1-2 to identify all of the ports on your device. Then see Figure 2-1 when you attempt to
make the various connections.

Follow these steps designed to guide you through a quick and correct installation of your Prestige
128MH.

A Warning On Connection Cables

The SMT RS-232 cable, WAN modem line, and Ethernet cable are very similar to each other. It is
important that you use the correct cable for each connection; otherwise, your Prestige could be
damaged.

Step 1. Connect Your Computer and Your Prestige

For the initial setup and configuration of your Prestige 128MH, you must use RS-232 and
communications software.

After your Prestige has been successfully installed, you can modify the configuration through a
remote Telnet connection. See Chapter 12 - Telnet Configuration and Capabilities for detailed
instructions on using Telnet to configure your Prestige 128MH.

Note on Connecting the RS-232 Cable to your Prestige

One RJ45 to RS-232 female adapter cable is included in your package. To make a RS-232
connection, first connect the RJ45 end of the cable to the CONSOLE port on the back panel of the
Prestige. Connect the other end to the RS-232 cable attached to the serial port (COM1, COM2, or
any other COM port) of your computer.

Step 2. Connect the Serial WAN Port

The Prestige 128MH has one serial WAN port (WAN port 1) which can be connected to a Dial-up
modem, a Leased Line modem, or ISDN TA (Terminal Adapter). The serial WAN port uses a
RJ45 connector. A cable is provided to convert RJ-45 to DB-25.

2-4

Prestige 128MH PSTN Router/Hub

Chapter 2 Hardware Installation & Initial Setup

Step 3. Connect the Internal 56K Modem Ports

The Prestige 128MH has two modem ports (LINE 1,2) which can be connected directly to your
local PSTN (Public Switch Telephone Network) via a telephone line. Use the RJ11 cables
included in the package to connect the modem ports labeled LINE 1 and LINE 2 directly to the
PSTN telephone line.

Step 4. Telephone/Fax Connection

The ports labeled PHONE 1 and PHONE 2 at the rear panel of your Prestige 128MH can be used
to connect a telephone and fax that will share the same lines, LINE 1 and LINE 2 respectively, as
the internal modems. Therefore, when the internal modem on LINE 1 or LINE 2 is not in use, you
can dial-out and place a call or send a fax by using the telephone or fax connected to PHONE 1 or
PHONE 2 ports of your Prestige.

Step 5. Connect an Ethernet Cable to your Prestige

The LAN ports 1,2,3, and 4 at the rear panel of your Prestige are used to connect to 10Base-T
Ethernet networks. 10Base-T networks use Unshielded Twisted Pair (UTP) cable and RJ-45
connectors that look like a bigger telephone plug with 8 pins. Two types of gray Ethernet cables
come with the package:

Ø Straight through cable (white tag): Connect your Prestige to your computer directly without a

hub.

Ø Crossover cable (red tag): Connect your Prestige to another 10Base-T Switch/Hub.

Step 6. Connect the Power Adapter to your Prestige

Plug a 16VAC 1200mA power adapter into the outlet labeled POWER on the rear panel of your
Prestige.

Prestige 128MH PSTN Router/Hub

Chapter 3 Internet Access Application

Chapter 3

Internet Access Application

This chapter shows you how to configure your Prestige 128MH for Internet Access.

3.1 IP Addresses and the Internet

If you are setting up and configuring your network for Internet Access for the first time, read
before proceeding. This section contains important information on how to assign IP addresses for
your network.

About the Internet

Conventionally, the "Internet" (with a capital I) refers the large-scale interconnected networks
across the world. The Internet uses exclusively the TCP/IP suite of protocols. The term "internet"
(lower case i), however, refers to any interconnected networks using any protocol. An internet can
be as simple as two hosts on a LAN, or it can be as complex as the Internet itself.

IP Addresses

Every machine on the Internet must have a unique address within that internet. An IP Address is
required for TCP/IP protocol and usually assigned by your ISP (Internet Service Provider) The IP
Address is the unique 32-bit number assigned to your Prestige. This address is typically expressed
as a sequence of four 8-bit numbers (0-255) in dotted decimal notation (separated by decimal
points), for example, 192.68.203.5.

Record the IP Address assigned by your network administrator or MIS specialist.

3-1

Prestige 128MH PSTN Router/Hub

Chapter 3 Internet Access Application

Note on IP Address Assignment

A unique 32-bit IP address is assigned to each host on the Internet. Similarly, every machine on
an internet must have a unique IP address. Do not assign an arbitrary address to any machine on
your network without prior consulting your network administrator.

IP Subnet Mask

A subnet mask is a 32-bit quantity that, when logically ANDed with an IP address, yields the
network number. For instance, the subnet masks for class A, B and C without subnetting are

255.0.0.0, 255.255.0.0 and 255.255.255.0, respectively.

The subnet mask is used to split the IP network addresses to create more network numbers. More
network numbers can be created by shifting some bits from the host ID to the network ID. For
instance, to partition a class C network number 192.68.135.0 into two, you shift 1 bit from the
host ID to the network ID. Thus the new subnet mask will be 255.255.255.128; the first subnet
will have network number 192.68.135.0 with hosts 192.68.135.1 to 192.68.135.126 and the
second subnet will have network number 192.68.135.128 with hosts 192.68.135.129 to

192.68.135.254.

It is recommended that you use the same subnet mask for all physical networks that share an IP
network number. Table 3-1 below lists the additional subnet mask bits in dot decimal notations.
To use Table 3-1, write down the original subnet mask and substitute the higher order 0s with the
dot decimal of the additional subnet bits. For instance, to partition your class C network

204.247.203.0 with subnet mask 255.255.255.0 into 16 subnets (4 bits), the new subnet mask
becomes 255.255.255.240.

Table 3-2 lists some examples of IP subnet masks and the number of hosts that are allowed.
Consult your network administrator or MIS specialist if you are unsure of this value.

255.255.255.224 30 27

255.255.255.255 1 32

An 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.

Prestige 128MH PSTN Router/Hub

Chapter 3 Internet Access Application

Private IP Adresses

If your networks are isolated from the Internet (for example, only between your two branch
offices) you can assign arbitrarily 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, as shown in Table 3-2.

For this reason, it is recommended that you choose your private network number from the list
provided in Table 3-3.

Table 3-3. Private Networks IP Addresses

Private IP Addresses

10.0.0.0 - 10.255.255.255

172.16.0.0 - 172.31.255.255

192.168.0.0 - 192.168.255.255

Assigning IP Addresses

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, the 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, you should consult your network administrator for the appropriate
IP addresses.

Note on IP Address Assignment

Regardless of your particular situation, do not create an arbitrary IP Address, always follow the
guidelines above. For more information on address assignment, refer to RFC 1597, Address
Allocation for Private Internets, and RFC 1466, Guidelines for Management of IP Address Space.

3.5 Single User Account

Typically, if there are multiple users on the LAN wanting to concurrently access the Internet, they
will have to subscribe to multiple IP addresses or a Class C sub-network from the ISP. In either
case, these two approaches will cost more than a single user account.

The Single User Account (SUA) feature allows customers to have the same benefits as having a
Class C address, but still only pay for one IP address, thus saving significantly on subscription
fees. (Check with your ISP before you enable this feature).

The Single User Account feature may also be used to connect to TCP/IP remote nodes other than
the ISP. For example, this feature can be used to simplify the allocation of IP addresses when
connecting branch offices to the corporate network.

Prestige 128MH PSTN Router/Hub

Chapter 3 Internet Access Application

The IP address for the SUA can be either fixed or dynamically assigned by the ISP (or other
remote node). In addition, you can also configure a server (for example, a Web server) on your
local network and make it accessible by outside users.

If you do not set a server IP address, SUA offers the additional benefit of firewall protection. With
SUA, even if no server is defined, all incoming inquiries will be filtered out by your Prestige even
if you do have a server on your network. This can prevent intruders from probing your system.

Your Prestige accomplishes this address sharing by translating the internal LAN IP addresses to a
single address that is globally unique on the Internet. For more information on IP address
translation, refer to RFC 1631, The IP Network Address Translator (NAT).

3.5.1 Advantages of SUA

In summary:
l SUA is an ideal cost-effective solution for small offices with less than 20 hosts using a LAN

to concurrently access the Internet or other remote TCP/IP network.

l SUA can provide one server address to be accessed by Remote Dial-in Users, thus

controlling the incoming packets.

l SUA can provide firewall protection if you do not configure a server IP address. All

incoming inquiries will be filtered out by your Prestige protecting the servers on your
network.

l UDP and TCP datagrams can be routed. In addition, ICMP echo can also be routed.

Figure 3-4 shows an example of a small office connected to the Internet via a SUA using the
Prestige. Note that if you enable the SUA feature, your local IP address MUST be selected from
the list of IP addresses for private networks as defined by the IANA.

3.6 Configuring Backup ISP Accounts

Sometimes it may be desirable to configure more than one ISP account for backup purposes. The
SUA feature can be enabled for all of these accounts, making it convenient to switch Internet
Service Providers in the event of a failure.

3.6.1 Configure a Backup ISP

To configure a backup ISP Account, follow these steps:

Step 1. Configure your primary ISP using Menu 4, as described earlier in this chapter.

Step 2. Enter Menu 11, then select the number of an unused remote node.

Step 3. In Menu 11.1, choose a name for your backup ISP account, then set the Active field to

[No], and enter your outgoing login name, password, and phone number(s). The
Remote IP Address field should be set to [1.1.1.1].

Step 4. In Menu 11.3, set the remote node's subnet mask to [0.0.0.0], and set RIP to [None].

Step 5. Save the new configuration.

3.6.2 To Switch ISP

Once you have done this, if you need to switch from your primary ISP to a backup ISP follow
these steps:

Step 1. Enter Menu 11 and select your Primary ISP.

Step 2. In Menu 11.1, set the Active field to [No].

Step 3. Enter Menu 11 again and select your Backup ISP.

Step 4. In Menu 11.1, set the Active field to [Yes].

You will now be able to access the Internet through the backup ISP Remote Node.

3.7 Editing Script Options

For some ISP, login script handshaking is required after a call connection. The Prestige provides
four set of programming scripts for this purpose. Each set of script is composed of an ‘expect’
string and a ‘send’ string. After capturing of the string in the field of ‘ expect’ , the Prestige will
send out the string in the field of ‘send’. If both of Expect and Send fields are empty, the Prestige
will terminate script handshaking. The Script Options display as shown in Figure 3-6.

Telecommuting

You can configure your Prestige to receive calls from Remote Dial-in Users (for example,
Telecommuters) and Remote Nodes. There are several differences between Remote Dial-in Users
and Remote Nodes, as summarized in Table 4-1.

Table 4-1. Remote Dial-in Users/Remote Nodes Comparison Chart

Remote Dial-in Users Remote Nodes

Your Prestige will only answer calls from Remote
Dial-in Users.

All Remote Dial-in Users share one common set of
parameters, as defined in the Default Dial In Setup
(Menu 13).

Remote Dial-in Users are individual users who dial
in to your Prestige directly from their workstations.

Your Prestige can make calls to or answer calls from
the Remote Node.

Each Remote Node can have its own set of
parameters such as Bandwidth On Demand,
Protocol, Security, etc.

Remote Nodes represent networks and are used for
LAN-to-LAN connections.

This chapter discusses how to setup Default Dial-in parameters for both Remote Node and
Remote Dial-in Users. The following sections give two examples of how your Prestige can be
configured as a dial-in server for either or both.

By default, your Prestige allows information for up to eight users to be kept. If more than eight
remote dial-in users can access your Prestige, you can use a separate RADIUS server to provide
remote authentication services. For details on using a separate RADIUS server, see the Using
RADIUS Authentication section in Chapter 11 - System Security.

PSTN Network

4.1 Telecommuting

Telecommuting enables people to work at remote sites and yet still have access to the resources in
the business office. Typically, a telecommuter will use a client workstation with TCP/IP or IPX
and dial-out capabilities (for example, a Windows 95 PC or a Macintosh) connected to a Modem
or an ISDN Terminal Adapter (ISDN TA). For telecommuters to call in to your LAN, you need to
configure a Dial-In User Profile for each telecommuter. Additionally, you need to configure the
Default Dial-In Setup to set the operational parameters for all dial-in users. You can configure up
to eight Remote Dial-in Users for your Prestige.

An example of Remote Dial-in User application, telecommuting, is shown in Figure 4-1.

4.2 Dial-In Server Application

Your Prestige can also be used as a dial-in server. This application allows your Prestige to provide
services for workstations on a remote network. For your Prestige to be set up as a dial-in server,
you need to configure the Default Dial-In Setup to set the operational parameters for incoming
calls. Additionally, you will have to create a Remote Node for the router on the remote network
(see Chapter 5 - Remote Node Configuration for LAN-to-LAN).

An example of your Prestige being used as a dial-in server is shown in Figure 4-2.

4.5 More on CLID

CLID allows your Prestige to authenticate the caller before a call is answered, thus saving the cost
of a connection. Your Prestige uses the caller ID in call setup message to match against the CLID
in the database.

Note on CLID and Modems

For your Prestige to use the CLID authentication, it is necessary that your modem also support
caller CLID.

Besides authentication, another application of CLID is to combine it with callback. For instance,
your company pays for the connection charges for telecommuting employees and you use your
Prestige as the dial in server. You can turn on both the CLID authentication and call back options
for the dial-in users. By doing so, all usage are charged to the company instead of the employees,
and your accounting department can avoid the hassles of accountability and reimbursement.

Remote Node Configuration for LAN-to-LAN

A Remote Node represents both a remote gateway and the internet behind it, across a WAN
connection. A Remote Node is required for placing calls to or answering calls from a remote
network. Note that when you use Menu 4 to configure the Internet, your Prestige will
automatically add a Remote Node for you. Once a Remote Node is configured properly, traffic to
the remote LAN will trigger your Prestige to make a call automatically (i.e., Dial On Demand).
Similarly, calls from the remote LAN will be answered automatically and security will be
checked.

In this chapter, we will discuss the parameters that are protocol independent. The protocol­dependent configuration will be covered in subsequent chapters. For TCP/IP, see Chapter 6. For
IPX, see Chapter 7. For Bridging, see Chapter 8.

minutes).

Default=300sec

5.1.2 Bandwidth on Demand

The Bandwidth on Demand (BOD) feature allows you to bundle two or three WAN Ports in one
connection. The additional ports are added and subtracted dynamically according to traffic
demand. The Prestige uses the Bandwidth Allocation Control Protocol (BACP) and the Multilink
Protocol (MP) to implement bandwidth on demand.

The configuration of bandwidth on demand is based on the Minimum and Maximum Ports of a
Remote Node. If Minimum and Maximum Ports are 1, BOD is disabled. Otherwise, BOD is
enabled.

When bandwidth on demand is enabled, a second port will be brought up if traffic on the initial
channel is higher than the high Target Utility number (for second port) for longer than the
specified Add Persist value. Similarly, the second port will be dropped if the traffic level falls
below the low Target Utility number for longer than the Subtract Persist value.

The Target Utility for a second port specifies the line utilization range at which you want your
Prestige to add or subtract bandwidth. The parameters are separated by a -. For example, 10-20
means the add threshold is 20 kbps and the subtract threshold is 10 kbps. Your Prestige will
perform bandwidth on demand only if it initiates the call. Addition and subtraction are based on
the value set in the BOD Calculation field. If this field is set to Transmit or Receive, then traffic in
either direction will be calculated to determine if a link should be added or dropped. Transmit will

only use outgoing traffic to make this determination, and Receive will only use incoming traffic to
make this determination.

If, after making the call to bring up a second port, the second port does not succeed in joining the
Multilink Protocol bundle (because the remote device does not recognize the second call as
coming from the same device), your Prestige will hang up the second port and continue with the
first port alone.

Similarly, a third port will be brought up or dropped based on the target utility for the third port.
The target utility for the third port is based on the Target Utility for the second port and
Bandwidth Increment for Additional Ports. For example, when Bandwidth Increment for an
Additional Port is 5 (Kbps) and the Target Utility for a second Port is 10-20; then the Target
Utility for a third port is 15-25.

See Menu 11.2 - Remote Node PPP Options in Figure 5-3 for a detailed description of BOD fields
and instructions on how to configure the PPP Options.

5.2 Leased Line Connection

The Leased Line Modem Connection feature allows you to connect the serial port WAN Port 1 to
a Leased Line Modem (Async). The Connection Type of WAN port 1 must be selected as [Leased]
in Menu 2.1 - Async WAN Port Setup.

Note on PPP Echo Request/Reply

In a Leased Line Connection, a [PPP Echo Request] packet is sent periodically to every link
(WAN Port). This is to verify if the link is up. When your Prestige receives a [PPP Echo Request]
packet, it will send another [PPP Echo Reply] packet back to the sender through the same link.
When [PPP Echo Reply] packets are not received for several times, your Prestige will drop the
link.

Note on Backup Function for Leased Line

You can also enable a Backup function for a Leased Line connection. When all the links in a
Leased Line Connection drop, your Prestige will pick up any available [Switch] WAN port to
place a phone call to establish a Backup connection. When any link (WAN port) in the Leased
Line Connection becomes available again, your Prestige will drop the backup connection. The
Backup function is usually enabled in a Leased Line Connection for LAN-to-LAN applications.

Outgoing: Authen

(*for backup line only)

This field sets the authentication protocol used for

outgoing calls.

Your Prestige supports two authentication protocols:

PAP (Password Authentication Protocol) and CHAP

(Challenge Handshake Authentication Protocol).

l PAP sends the user name and password in plain

text.

l CHAP scrambles the password before it is sent

over the wire.

Generally speaking, CHAP is more secure than PAP;

however, PAP is readily available on more platforms.

The recommendation is to use CHAP whenever

possible. Turning off the authentication is STRONGLY

discouraged.

Options for this field are:

l CHAP/PAP - Your Prestige will try CHAP when

CHAP is requested by the Remote Node or PAP
when PAP is requested by the Remote Node.
