Preface

About Your Router/Hub

Congratulations on your purchase of the Prestige 128IMH ISDN/Modem Router/Hub.
The Prestige 128IMH is a high-performance bridge/router that offers a complete solution for your

WAN (Wide Area Network) applications such as Internet access, multi-protocol LAN-to-LAN
connections, telecommuting and remote access over ISDN (Integrated Service Digital Network).

With the built-in V.90 modem, the Prestige is equally capable of supporting modem calls.
The Prestige 128IMH supports multi-protocol routing for TCP/IP and Novell IPX, as well as

transparent bridging for other protocols. With the built -in 4-port Ethernet 10Base-T hub, you get
the added benefit of eliminating the clutter caused by an external hub.

Your Prestige 128MH is easy to install and to configure since you do not need to set any switches.
The Prestige Web Configurator is a JAVA based utility designed that allows users to access the

Prestige’s management settings via a Worldwide Web browser. Moreover, all functions of the
Prestige128MH are software configurable via the SMT (System Management Terminal) Interface.
The SMT is a menu-driven interface that you can access from either a VT100 compatible terminal

This user's manual shows you how to configure and manage your router.
The fourteen chapters of this manual consists are designed to guide you through the configuration

of your Prestige 128IMH for its various applications.

Ordering an ISDN Line

If you do not have the ISDN line installed already, we suggest that you order it from your
telephone company as soon as possible to avoid the long waits common when ordering a new
line.

Preface xxiii

Prestige 128IMH ISDN Modem/ Router/Hub

If you have an ISDN line installed and working, you can reference the following sections to
insure that your line is set up properly to allow all the features of your Prestige to operate.

To order a new ISDN line, do the following:

1. Contact your local telephone company’s ISDN Ordering Center to find out what type of ISDN
service is available and the switch type.

2. Provide your telephone company with the line provisioning information for that switch type,
which can be found at Chapter 15 of this manual. This insures proper operation of all of the
Prestige’s features with the ISDN line.

3. When the telephone company installs your ISDN line, please be sure to obtain and write down the
following information for future use:

• ISDN switch type

• ISDN telephone number(s)

Completing the Setup Information Worksheet

Before you continue, locate the worksheet at Chapter 15 . This information worksheet has been
provided to help you collect the necessary information needed for setup and installation in the
following chapters.

Collecting General Setup Information

The Prestige requires certain 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.

Route IP Field - For Internet access, you need to enable the Route IP Field.
You have now collected all of the general setup information you need. Please make sure that you

have entered all the values onto the worksheet before proceeding to the next section.

Prestige 128IMH ISDN Modem/ Router/Hub

Collecting ISDN Phone Line Information

Once your ISDN line is installed by the telephone company, you need to use the following
information to complete the worksheet and configure your Prestige. Much of this information is
provided by your telephone company upon intallation of the ISDN line.

Table 1-1 ISDN Phone Line Info

Switch Type Geography No of Phone #'s

DSS1 Europe, Asia 2

Switch Type - This is the type of switch used by your telephone company. Check with your
telephone company and choose the appropriate option on the worksheet.

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

Telephone Number(s) - Record on the worksheet the telephone number(s) given to you by your
telephone company. Some switch types only have one telephone number. These telephone
numbers should be in a standard digit format (for example, 5551212). Please note that these fields
only accept digits, so ‘-’ and spaces are not allowed.

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 Phone1 or Phone2 if you wish to route the incoming analog call for this telephone
number to PHONE port number 1 or 2.

Supplemental Service Activation Keys – Sometimes called ‘buttons,’ most of the supplemental
services supported by the Prestige require that an activation key be set before a feature can be
used.

You have now collected all of the necessary information about your ISDN telephone line. Make
sure that these values are entered into your ‘Setup Information Worksheet’ before you continue to
the next section.

Preface xxv

Prestige 128IMH ISDN Modem/ Router/Hub

Collecting Ethernet Setup Information

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., 192.168.1.1.

Record the IP Address into the worksheet as assigned by yo ur network administrator. Please note
that every machine on an internet must have a unique IP address - do not assign an arbitrary
address to any machine. If you are not sure as to which IP address to assign to the Prestige,
contact your LAN administrator or refer to Chapter 4 of this guide for more details.

IP Subnet Mask - This field is required for TCP/IP protocol. 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 automatically calculates 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.

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.

Note on Bridging

When bridging is enabled, your Prestige forwards any packet that it does not route. Without
bridging, the packets that the Prestige does not route are simply discarded. Compared to routing,
bridging generates far more traffic for the same network protocol and consumes more CPU cycles
and memory.

Prestige 128IMH ISDN Modem/ Router/Hub

2.8 European ISDN Setup Menus

Menu 2 is for you to ente r the information about your ISDN line. Please note that the Prestige
only accepts digits in phone number fields; please do no include ‘-‘ or spaces in these fields.

2.8.1 Switch Type

The only switch type supported in Europe is DSS-1.

2.8.2 MSN and Subaddress

Depending on your location, you may have Multiple Subscriber Number (MSN) where the
telephone company gives you more than one number for your ISDN line. You can assign each
number to a different port, e.g., the first number to data calls, the second to A/B adapte r 1 and so
on. Or the telephone company may give you only one number, but allow you to assign your own
subaddresses to different ports, e.g., subaddress 1 to data calls and 2 to A/B adapter 1.

2.8.3 Incoming Call Routing

The Incoming Phone Number Matching setting governs how incoming calls are routed. If you
select Multiple Subscriber Number (MSN) or Called Party Subaddress, a call (either
ISDN data or analog) is routed to the port that matches the dialed number; if no match is found,
the call is dropped.

If you select Don’t Care, then all data calls are routed to the Prestige itself. Analog calls,
however, are routed to either A/B adapter 1 or 2, or simply ignored, depending on the Analog
Call Routing field.

2.8.4 Global Calls

A global call is an incoming analog call where the switch did not send the dialed number. This
happens most often when the call originates from an analog telephone line.

If you specify explicit matching, i.e., Incoming Phone Number Matching is either MSN or
Called Party Subaddress, then global calls are always ignored. If it is Don’t Care and Analog

2-14 Hardware Installation and Setup

Prestige 128IMH ISDN Modem/ Router/Hub

Call Routing is either A/B Adapter 1 or 2, then the Prestige uses Global Analog Call to decide
how to handle global calls. If you set Global Analog Call to Accept, then global calls are
routed to the port according to the Analog Call Routing setting; if you set Global Analog Call to
Ignore, then the Prestige ignores all global calls. If Analog Call Routing is Ignore to begin
with, then all analog calls, including global calls, are ignored.

2.8.5 Modem Cal ls

The built -in modem is internally connected to A/B adapter 2. If you wish to receive modem calls,
you must set the A/B Adapter 2 Accepts Modem Call field to Enable. When this field is
enabled, only the modem receives the incoming analog calls routed to A/B adapter 2 according to
the description above; the external device will not ring. Note that this field only controls the
incoming calls; you can still place outgoing modem calls even if this field is Disable.

2.8.6 PABX Outside Line Prefix

A PABX (Private Automatic Branch eXchange) generally requires you to dial a number (a single
digit in most cases) when you need an outside line. If your Prestige is connected to a PABX,
enter this number in PABX Outside Line Prefix, otherwise, leave it blank.

Please note that the PABX prefix is for calls initiated by the Prestige only. If you place a call

This allows you to place a call on hold while you answer another incoming call on the same
telephone (directory) number. By default call waiting is disabled on both telephone ports, but can
be enabled on either port from Menu 2.1

How to use call waiting

The Call Waiting feature on your ISDN line works in exactly the same way it does on a regular
analog line. After hearing a call waiting indicator tone, press and immediately release the flash
button on your telephone. This puts your current call on hold and answers the incoming call.

Figure 2-10 ISDN Advanced Setup

The Calling Line Indication, or Caller ID, governs whether the other party can see your number
when you call. If set to Enable, the Prestige sends the caller ID and the party you call can see
your number, otherwise, the caller ID is blocked.

When you are finished, press ENTER at the message: ‘Press ENTER to confirm’, the Prestige
uses the information that you entered to initialize the ISDN line. It should be noted that whenever
the switch type is changed, the ISDN initialization takes slightly longer.

At this point, the Prestige asks if you wish to test your ISDN. If you select Yes, the Prestige will
perform a loop-back test to check the ISDN line. If the loop-back test fails, please note the error

3.2 TCP/IP Parameters

3.2.1 IP Address and Subnet Mask

Similar to the houses on a street that share a common street name, the machines on a LAN share
one common network number, also.

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 3
numbers specify the network number while the last number identifies an individual works tation
on that network.

Once you have decided on the network number, pick an IP address that is easy to remember, e.g.,

192.168.1.1, for your Prestige.
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.

3.2.2 RIP Setup

RIP (Routing Information Protocol) allows a router to exchange routing information with other
routers. The RIP Direction field controls the sending and receiving of RIP packets. When set to
both, the Prestige will broadcast its routing table periodically and incorporate the RIP information

3-2 Internet Access

Prestige 128IMH ISDN Modem/ Router/Hub

that it receives; when set to none, it will not send any RIP packets and will ignore any RIP
packets received.

The Version field controls the format and the broadcasting method of the RIP packets that the
Prestige sends (it recognizes both formats when receiving). RIP-1 is universally supported; but
RIP-2 carries more information. RIP-1 is probably adequate for most networks, unless you have a
unusual network topology.

Both RIP-2B and RIP-2M sends the routing data in RIP -2 format; the difference being that RIP-
2B uses subnet broadcasting while RIP-2M uses multicasting. Multicasting can reduce the load
on non-router machines since they generally do not listen to the RIP multicast address and so will
not receive the RIP packets. However, if one router uses multicasting, then all routers on your
network must use multicasting, also.

By default, RIP direction is set to Both and the Version set to RIP-1.

3.2.3 DHCP Configuration

DHCP (Dynamic Host Configuration Protocol) allows the ind ividual clients (workstations) to
obtain the TCP/IP configuration at start-up from a centralized DHCP server. The Prestige has
built-in DHCP server capability, enabled by default, which means it can assign IP addresses, an
IP default gateway and DNS servers to Windows 95, Windows NT and other systems that support
the DHCP client.

IP Pool Setup

The Prestige is pre-configured with a pool of 32 IP addresses starting from 192.168.1.33 to

192.168.1.64. This configuration leaves 31 IP addresses (excluding the Prestige itself) in the
lower range for other server machines, e.g., server for mail, FTP, telnet, web, etc., that you may
have.

DNS Server Address

DNS (Domain Name System) is for mapping a domain name to its corresponding IP addr ess and
vice versa, e.g., the IP address of www.zyxel.com is 204.217.0.2. The DNS server is extremely
important because without it, a user must know the IP address of a machine before s/he can access

Internet Access 3-3

Prestige 128IMH ISDN Modem/ Router/Hub

it. The DNS server addresses that you enter in the DHCP setup are passed to the client machines
along with the assigned IP address and subnet mask.

There are two ways that an ISP disseminates the DNS server addresses. The first is for an ISP to
tell a customer the DNS server addresses, usually in the form of an information sheet, when s/he
signs up. If your ISP does give you the DNS server addresses, enter them in the DNS Server
fields in DHCP Setup.

Some ISP’s choose to pass the DNS servers using the DNS server extensions of PPP IPCP (IP
Control Protocol) after the connection is up. If your ISP did not give you explicit DNS servers,
chances are the DNS servers are conveyed through IPCP negotiation. The Prestige supports the
IPCP DNS server extensions through the DNS proxy feature.

If the Primary and Secondary DNS Server fields in DHCP Setup are not specified, i.e., left as

0.0.0.0, the Prestige tells the DHCP clients that it itself is the DNS server. When a workstation
sends a DNS query to the Prestige, the Prestige forwards the query to the real DNS serve r learned
through IPCP and relays the response back to the workstation.

Please note that DNS proxy works only when the ISP uses the IPCP DNS server extensions. It
does not mean you can leave the DNS servers out of the DHCP setup under all circumstances. If
your ISP gives you explicit DNS servers, make sure that you enter their IP addresses in the
DHCP Setup menu. This way, the Prestige can pass the DNS servers to the workstations and the
workstations can query the DNS server directly without the Prestige ’s intervention.

3.5 Single User Account

Typically, if there are multiple users on the LAN wanting to concurrently access the Internet, you
will have to lease a block of legal, or globally unique, IP addresses from the ISP.

The Single User Account (SUA) feature allows you to have the same benefits as having multiple
legal addresses, but only pay for one IP addr ess, thus saving significantly on the subscription fees.
(Check with your ISP before you enable this feature).

illustrates a typical Single User Account topology.

The Single User Account feature may also be used on connections to remote networks 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.

Internet Access 3-11

Prestige

The SUA network appears as a
single host to the Internet.

Figure 3-4 Single User Account Topology

Prestige 128IMH ISDN Modem/ Router/Hub

The IP address for the SUA can be either fixed or dynamically assigned when a call is connected.
In addition, you can designate servers, e.g., a web server and a telnet server, on your local
network and make them accessible to the outside world.

If you do not define any server, SUA offers the additional benefit of firewall protection. If no
server is defined, all incoming inquiries will be filtered out by your Prestige and thus preventing
intruders from probing your network.

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 a cost-effective solution for small offices with less than 20 hosts to access the

Internet or other remote TCP/IP networks.

l SUA supports servers to be accessible to the outside world.
l SUA can provide firewall protection if you do not specify a server. All incoming inquiries

will be filtered out by your Prestige.

l UDP and TCP packets can be routed. In addition, partial ICMP, including echo and trace

route, is supported.

3.6 Configuring Backup ISP Accounts

If you have more than one ISP account, you can configure the secondary ISP as a backup. You
can switch to the backup ISP in the event that the primary ISP is out of service. The SUA feature
can be enabled for all these accounts.

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 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.

Please note that the remote IP address of 1.1.1.1 is only a placeholder to avoid conflicting with
that of the primary ISP, which is implicitly set at 0.0.0.0. When the backup ISP is activated, the
remote IP address of 1.1.1.1 combined with the subnet mask of 0.0.0.0 creates a default route
that is equivalent to the one derived form the primary ISP.

3.6.2 To Switch ISP

Follow these steps when you need to switch from your primary ISP to a backup ISP:

Step 1. Enter Menu 11 and select your Primary ISP.
Step 2. In Menu 11.1, set the Active field to No.

3-14 Internet Access

Prestige 128IMH ISDN Modem/ Router/Hub

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.

Remote Node Configuration

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. Once a
remote node is configured correctly, traffic to the remote network will trigger your Prestige to
make a call automatically, i.e., Dial On Demand.

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 5, for
IPX, see Chapter 6 and for Bridging, see Chapter 7.

This value specifies the number of idle seconds that

data is transmitted from your Prestige. Administrative
packets such as RIP are not counted as data. The default
is 300 seconds (5 minutes). This option only applies when
the Prestige initiates the call.

Default=Blank

Default=300sec

4.1.2 Nailed-up Connection

A nailed-up connection is a dial-up line where the connection is always up regardless of traffic
demand. The Prestige does two things when you specify a nailed-up connection. The first is that
idle timeout is disabled. The second is that the Prestige will try to bring up the connection at
power-on and whenever the connection is down.

A nailed-up connection can be very expensive for obvious reasons. Please do not specify a nailed­up connection unless your telephone company offers flat-rate service or you need a constant
connection and the cost is of no concern.

4.1.3 Outgoing Authentication Protocol

Generally speaking, you should employ the strongest authentication protocol possible, for obvious
reasons. However, some vendor’s 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 you encounter the case where the

4-6 Remote Node Configuration

Prestige 128IMH ISDN Modem/ Router/Hub

peer disconnects right after a successful authentication, please make sure that you specify the
correct authentication protocol when connecting to such an implementation.

4.1.4 PPP Multilink

The Prestige uses the PPP Multilink Protocol (PPP/MP) to bundle multiple links in a single
connection to boost the effective throughput between two nodes. The bundle works best when the
member links are of the same type of call (e.g., modem vs. ISDN) and at approximately the same
speed.

Due to the fragmentation/reconstruction overhead associated with MP, you may not get a linear
increase in throughput when a link is added.

The number of links in an MP bundle can be statically configured, or dynamically determined at
runtime, as explained in the following section.

4.1.5 Bandwidth on Demand

The Bandwidth on Demand (BOD) feature adds or subtracts links dynamically according to
traffic demand. After the initial call, the Prestige uses BAP (Bandwidth Allocation Protocol) to
ask the peer for additional telephone number if BACP (Bandwidth Allocation Control Protocol) is
negotiated. Otherwise, the Prestige uses the statically configured (primary and seconda ry)
telephone numbers of the remote node.

The configuration of bandwidth on demand focuses on the Base Transmission Rate (BTR) and the
Maximum Transmission Rate (MTR). The relationship between BTR and MTR are shown below:

Table 4-2 BTR v MTR for BOD

channel(s) used

Remote Node PPP Options

When bandwidth on demand is enabled, a second channel will be brought up if traffic on the
initial channel is higher than the high Target Utility number for longer than the specified Add

Persist value. Similarly, the second channel will be dropped if the traffic level falls below the low
Target Utility number for longer than the Subtract Persist value.

The Target Utility specifies the line utilization range at which you want the Prestige to add or
subtract bandwidth. The range is 30 to 64 kbps (kilobits per second). The parameters are
separated by a ‘-’. For example, ‘30-60’ means the add threshold is 30 kbps and subtract threshold
is 60 kbps. The Prestige performs 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 included 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 channel, the second channel 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), the Prestige will hang up the second call and continue with
the first channel alone.

5.1.2 Static Route Setup

Static routes tell the Prestige routing information that it cannot learn automatically through other
means. This can arise in cases where RIP is disabled on the LAN or a remote network is beyond
the one that is directly connected to a remote node .

Each remote node specifies only the network to which the gateway is directly connected, and the

Router 1

Prestige has no knowledge of the networks beyond. For instance, the Prestige knows about
network N2 in the following diagram through remote node R. However, the Prestigeis unable to
route a packet to network N3 because it doesn’t know that there is a route through remote node R.
The static routes are for you to tell the Prestige about the networks beyond the remote nodes.

Chapter 6

IPX Configuration

This chapter shows you how to configure the IPX parameters of the Prestige.

6.1 IPX Network Environment

Novell bundles the protocol stack, the server software and routing functionality in their NetWare
server products. So a NetWare server is not only a file or print server, it is also a router.

6.1.1 Network and Node Number

Every IPX machine has a network number and a node number, together they form the complete
address of the machine. The IPX network number is a 32-bit quantity and is usually expressed in
8 hexadecimal digits, e.g., 0893A8CF. The host number is a 48-bit quantity and usually is taken
from the MAC (Media Access Control) address of the Ethernet hardware, so you don’t have to
explicitly configure the node number.

An IPX client obtains its network number from a server that has the network numbers statically
configured. If there are multiple servers on a network, only one server need to have the network
numbers configured, and all other stations (clients and servers) can obtain the network numbers
from it. The server with configured network numbers is called a seed router.

If you have a NetWare server on the same LAN as the Prestige, we recommend that you set up a
NetWare server as a seed router. Even though the Prestige is capable as a seed router, a NetWare
server offers a much more extensive facility for network management.

IPX Configuration 6-1

Prestige 128IMH ISDN Modem/ Router/Hub

6.1.2 Frame Types

IPX can run on top of four different frame types on the Ethernet. These frame types are 802.2,

802.3, Ethernet II (DIX), and SNAP (Sub-Network Access Protocol). Each frame type is a
separate logical network, even though they exist on one physical cable.

Although there are four frame types available on the Ethernet, you should configure as few frame
types as possible on your NetWare server and use automatic frame detection on the clients to
simplify management and to reduce network overhead.

6.1.3 External Network Number

Each of the four logical networks (based on frame type) has its own external network number.

6.1.4 Internal Network Number

In addition to the externa l network numbers, each NetWare server has its own internal network
number that is a virtual network to which the server is attached. It is important to remember that
every network number must be unique for that entire internetwork, either internal or exte rnal.

6.2.1 Prestige on LAN with Server

If your Prestige is on a LAN with a seed router, you do not need to configure the LAN network
numbers. Your Prestige will learn the network number from the seed router and add the routes to
its routing table.

6-4 IPX Configuration

Prestige 128IMH ISDN Modem/ Router/Hub

6.2.2 Prestige on LAN without Server

Each IPX network must have a seed router. If you only have NetWare clients on your network,
then you must configure the Prestige as a seed router and set up unique network numbers for each
frame type enabled using the Ethernet Setup Menu.

6.3 IPX Spoofing

Your Prestige comes with several pre-defined call filters designed to prevent certain IPX packets
from triggering a call to a remote node.

The built -in call filters are defined as follows:
l Block periodical RIP (Routing Information Protocol) and SAP (Service Advertising

Protocol) response messages.

l Block NetWare serialization packets.
l Allow SAP and RIP inquiry packets.
