Connection proﬁles

A connection proﬁle is a set of parameters that tells the Netopia ISDN Router how to connect to a remote destination. Connection proﬁles are also used to make out-bound calls and optionally to help answer calls.

Small Ofﬁce Models The Netopia ISDN Router Small Ofﬁce models support up to 4

different connection proﬁles.

Corporate Models The Netopia ISDN Router Corporate models support up to 16

different connection proﬁles. Each connection proﬁle you set up allows the Netopia ISDN Router

to connect your network to another network that also has an ISDN line and uses IP or IPX over the Point-to-Point Protocol (PPP).

To go to the Connection Proﬁles screen, select Connection Proﬁles in the WAN Setup screen.

■ Dynamic ( default setting), to allow calls to use the two B

channels in a dynamic manner. This option allows the connection proﬁle to use one or both channels at any time during a call. The decision to alternately use or drop the second B channel is based on an algorithm that looks at trafﬁc volume over time. With Dynamic, one B channel may be relinquished to accept an incoming call through or when a second connection proﬁle is used to make a call. See Appendix D for information on “Dynamic B-channel usage” on page D-4 for more information.

Note: To relinquish the B channel for an incoming call requires telco provisioning of ACO (Additional Call Offering).

■ 1 B-Channel to force a call to remain within one B channel.

■ 2 B-Channels to force a call to use both B channels.

(Throughput connection will generally run at 128k.)

■ 2 B Pre-emptable to allow calls to use the 2B channels in

a dynamic, pre-emptable manner. This option is very similar to Dynamic, in that the second B channel may be relinquished to accept an incoming call or to initiate a second outgoing call. However, 2B Pre-emptable will always try to add a second B channel to the call when the second channel is otherwise unused, much like a ﬁxed 2 B channel selection.

Answering calls

Netopia can answer calls as well as initiate them. To answer calls, Netopia uses an answer proﬁle, just as it uses a connection proﬁle to make calls. Netopia’s answer proﬁle controls how incoming calls are set up, authenticated, ﬁltered, and more.

How the answer proﬁle works

The answer proﬁle works like a guard booth at the gate to your network: it only scrutinizes incoming calls. Like the guard booth, the answer proﬁle allows calls based on a set of criteria that you deﬁne.

The main criterion used to check calls is whether they match one of the connection proﬁles already deﬁned. If PAP or CHAP authentication is being used, the answer proﬁle checks that the incoming call’s name and password/secret match the receive name and password/secret of a connection proﬁle. If PAP or CHAP are not being used, an incoming call is matched to a connection proﬁle using the remote network’s IP address (that is, the caller is deﬁned as the destination of a particular connection proﬁle).

You could instruct the answer proﬁle to allow calls in even if they fail to match a connection proﬁle. Continuing the guard booth analogy, this would be like removing the guards or having them wave all calls in, regardless of their source.

If an incoming call is matched to an existing connection proﬁle, the call is accepted. All of that connection proﬁle’s parameters, except for authentication, are adopted for the call.

If an incoming call is not required to match a connection proﬁle, and fails to do so, it is accepted as a standard IP connection. Accepted, unmatched calls adopt the call parameter values set in the answer proﬁle (see below).

Conﬁguring ISDN Connections 2-27

This setting requires that the calling number match a profile to answer.

Conﬁguring ISDN Connections 2-29

Calling Number Authentication (CNA), is an application of caller ID. It is a method of verifying that an incoming call is originating from an expected site. Using CNA, you can increase the security of your network by requiring that callers not only possess the correct PAP or CHAP information, but also that they are calling from a particular physical location. CNA should be available where caller ID services are available, but you will need to consult with your ISDN service provider to ﬁnd out if your ISDN line is provisioned for caller ID.

CNA works by checking the calling number that the Netopia ISDN Router receives during the initial setup phase of an incoming call against the stored Calling Number deﬁned in each connection proﬁle. When a match occurs, the incoming call is handled by the connection proﬁle containing the matched number.

Using CNA can also provide cost saving because calls are not billed during the CNA phase. With CNA, a caller can set up a connection to the Netopia ISDN Router without incurring any charges by accessing a dial-back connection proﬁle. If the callers rates are higher than those charged to the Netopia ISDN Routers return call, then using CNA has saved the difference.

2-30 Netopia ISDN Router Reference Guide

Conﬁguring proﬁles for incoming calls.

If the answer proﬁle must

match...

To force incoming calls to match connection proﬁles, select Must Match a Deﬁned Proﬁle and toggle it to Yes. Incoming calls that

cannot be matched to a connection proﬁle are dropped. To allow unmatched calls to be accepted as standard IP or IPX connections, toggle Must Match a Deﬁned Proﬁle to No.

Note: If Must Match a Deﬁned Proﬁle is set to Yes, the items below it will not appear.

If Must Match a Deﬁned Proﬁle is set to Yes, the answer proﬁle only accepts calls that use the same authentication method deﬁned in the Authentication item. If PAP or CHAP are involved, the caller must have a name and password or secret that match one of the connection proﬁles. The caller must obtain these from you or your network administrator before initiating the call.

For example, if Must Match a Deﬁned Proﬁle is set to Yes, and Authentication is set to PAP, then only incoming calls that use PAP and match a connection proﬁle will be accepted by the answer proﬁle.

Note: If authentication in the default answer proﬁle is set to CHAP, the value of the CHAP Challenge Name item must be identical to the value of the Send Host Name item of the connection proﬁle to be matched by the caller.

If the answer proﬁle

doesn’t have to match...

If Must Match a Deﬁned Proﬁle is set to No, Authentication is assumed to be None, even if you’ve set it to PAP or CHAP. The answer proﬁle uses the caller’s IP address to match a connection proﬁle. However, the answer proﬁle cannot discover a caller’s subnet mask; it assumes that the caller is address:

■ Class A addresses are assumed to have a mask of 255.0.0.0

■ Class B addresses are assumed to have a mask of

■ Class C addresses are assumed to have a mask of

not

subnetting its IP

255.255.0.0

255.255.255.0. Class C address ranges are generally the

Conﬁguring ISDN Connections 2-31

most common subnet allocated.

If a remote network has a non-standard mask (that is, it uses subnetting), the only way for it to successfully connect to the Netopia ISDN Router is by matching a connection proﬁle. In other words, you will have to set up a connection proﬁle for that network.

models only

You can set the following default parameters for incoming calls:

■ Authentication

■ Force 56K on Answer

■ LZS Data Compression

If Must Match a Deﬁned Proﬁle is set to No, you can also set the following parameters for accepted calls that do not match a connection proﬁle:

■ B-Channel Usage

■ Idle Timeout

■ Filter Set

All of these parameters are similar to the connection proﬁle parameters of the same names. To ﬁnd out how to set them, see

Connecting Your Local Network

In this chapter, you will learn how to physically connect the Netopia ISDN Router to your local area network (LAN). Before you proceed, make sure the Netopia ISDN Router is properly conﬁgured. You should have conﬁgured the Router using Easy Setup or with custom settings.

3-1

Overview

You can connect the Netopia ISDN Router to an IP or IPX network that uses Ethernet. If you have a PC LAN using IP over Ethernet, you can connect it to the Netopia ISDN Router’s Ethernet port. You can also connect the Router to an AppleTalk network that uses either Ethernet or LocalTalk.

AppleT alk networks based on Ethernet cabling (EtherTalk) connect to all models of the Router through their Ethernet ports. Apple Macintosh computers using native IP also connect to the Router’s Ethernet port.

AppleTalk networks based on LocalTalk cabling connect to the 400 series models through their LocalTalk ports. If you have both kinds of AppleTalk networks, you can connect one to the Netopia ISDN Router’s LocalTalk port and the other to its Ethernet port. AppleT alk trafﬁc will be routed between these two networks.

Caution! Before connecting the Netopia ISDN Router to any AppleTalk LANs

that contain other AppleTalk routers, you should read “Routers and seeding” in “AppleTalk Networks” on page 6-1.

See the sections later in this chapter for details on how to connect the Netopia ISDN Router to the two types of networks.

Application software: This is the software you use to send e-mail, browse the World Wide Web, read newsgroups, etc. These applications may require some conﬁguration. Examples include the Eudora Light e-mail client, and the web browsers Microsoft’s Internet Explorer and Netscape Navigator.

TCP/IP stack: This is the software that lets your PC or Macintosh communicate using Internet protocols. TCP/IP stacks must be conﬁgured with some of the same information you used to conﬁgure the Netopia ISDN Router. There are a number of TCP/IP stacks available for PC computers. Windows 95 includes a built-in TCP/IP stack. Macintosh computers use either MacTCP or Open Transport.

Ethernet: Ethernet hardware and software drivers enable your PC or Macintosh computer to communicate on the LAN.

EtherTalk: This is the AppleTalk protocol used over Ethernet.

Connecting Your Local Network 3-3

Once the Netopia ISDN Router is properly conﬁgured and connected to your LAN, PC and Macintosh computers that have their required components in place will be able to connect to the Internet or other remote IP networks.

Connecting to a LocalTalk network—for 400 series models

Connect one end of the LocalTalk cable to the Netopia ISDN Router’s LocalTalk port. Connect the other end of the cable to your LocalTalk network.

If your LocalTalk network is not based on standard PhoneNET cabling, use the PhoneNET-to-LocalTalk adaptor cable provided. Connect the adaptor cable’s RJ-11 connector to the Netopia ISDN Router. Connect the cable’s mini-DIN-3 connector to your LocalTalk network.

The LocalTalk port is terminated, so the Netopia ISDN Router should only be used at the end of your LocalT alk network. Be sure to observe standard LocalT alk rules governing maximum cable lengths and limits on the number of AppleTalk hosts.

Note: Make sure you either the ISDN port or one of the EtherWave ports.

IP Setup

4-1

The Netopia ISDN Router uses Internet Protocol (IP) to communicate both locally and with remote networks. This chapter shows you how to conﬁgure the Router and to effectively route IP trafﬁc. You also learn how to conﬁgure the Router to serve IP addresses to hosts on your local network.

Small Ofﬁce models only Small Ofﬁce models of the Netopia ISDN Router also include a

special IP feature called Network Address Translation (NAT). NAT is a powerful feature that allows the user to represent an entire

LAN to the outside world as a single IP address. Instead of having a separate IP address for each computer on the network, users now need only one IP address called a proxy address.

4-2 Netopia ISDN Router Reference Guide

Key Features of IP Network Address Translation (NAT)

■ NAT is selectable on a per connection basis, optionally allowing

real addresses to be used for intranet connections and proxied addresses to be used for Internet connections.

■ The NAT user can use any combination of proxied and

unproxied addresses simultaneously on the two B-channels. For instance, one unproxied address connection proﬁle can be used to connect to a central ofﬁce, while another proxied address connection proﬁle can simultaneously connect the user’s Netopia ISDN Router and LAN to the Internet.

■ The single proxy address is acquired at connection time from

the answering side. The address can be assigned by the remote router from either a dynamic pool of addresses or a ﬁxed, static address.

Using NAT

■ Security is made simpler and more reliable by only having to

ﬁrewall one IP address and by obscuring the internal network structure from the Internet.

Follow these steps to use NAT.

1. Pick a network number for your local (internal) network. This

can be any IP address range you want. For this example, we will use 10.0.0.0.

Note: The outside world (the external network) will not see this network number.

2. Using the internal network number, assign addresses to the

local nodes on your LAN. For example, you may assign

■ 10.0.0.1 to your Netopia ISDN Router

■ 10.0.0.2 to a node running as a World Wide Web server

■ 10.0.0.3 to an FTP server

■ 10.0.0.4 to a Macintosh computer

IP Setup 4-3

■ 10.0.0.5 to a Windows 95 PC

3. Create a connection proﬁle for your ISP or other remote network. See “Adding a connection proﬁle” on page 2-9. In the IP Proﬁle Parameters screen, toggle Address Translation Enabled to Yes, to turn on NAT for this proﬁle.

4. When your Netopia ISDN Router calls the ISP, the remote router that answers the call assigns your Netopia ISDN Router an IP address that external users use to communicate with your network. To view this address, go to the QuickView menu and check More Info in the Current ISDN Connection Status section of the proﬁle.

In the following example screen, 192.163.100.6 is assigned to the calling Netopia ISDN Router.

Internal users can access the Internet as they always do; the external Internet, however, views all trafﬁc that the computers generate on the internal network as originating from

192.163.100.6. Similarly, all trafﬁc your network receives is addressed to 192.163.100.6.

4-4 Netopia ISDN Router Reference Guide

Associating port numbers to nodes

When an IP client, such as a Netscape or Microsoft Internet Explorer web browser, wants to establish a session with an IP server, such as a web server, the client must know the IP address to use and the IP port where the trafﬁc is to be directed.

Just as an IP address speciﬁes a particular computer on a network, ports are addresses that specify a particular service in a computer. There are many universally agreed-upon ports assigned to various services. For example:

■ Web servers use port number 80.

■ FTP servers use port number 21.

■ Telnet uses port number 23.

■ SNMP uses port number 161.

The Netopia ISDN Router lets you associate these and other port numbers to nodes on your internal LAN. See “Associating port

numbers to nodes,” beginning on page 4-4 for details on how to

accomplish this.

IP Setup 4-5

NAT guidelines

Observe the following guidelines when using NAT.

■ Only one node per internal network can supply a speciﬁc

service. In our example, if there is more than one web server on the 10.0.0.0 network, the Netopia ISDN Router would not be able to differentiate incoming web trafﬁc destined for each web server. Similarly, external users cannot ping internal nodes, although the Netopia ISDN Router can respond to ping requests.

As mentioned earlier, you can enable NAT on one connection proﬁle, disable it on another, and use the two proﬁles simultaneously. The proﬁles might have the following attributes:

■ A “normal” proﬁle connects to your branch or main ofﬁce. Y our

company network administrator has assigned you a local IP address range that is consistent with the address space assigned to your company so that you seamlessly integrate when connected. The remote IP address and mask for this proﬁle deﬁne only the company’s address space, so that the only IP trafﬁc you send over this connection is for hosts and servers within your company.

■ A NAT proﬁle connects to the internet via an ISP. Even though

the ISP assigns you a dynamic address each time you connect, there will be no conﬂict of address spaces, since NAT makes the corporate address you use locally invisible to the ISP. You enter the ISP’s remote IP address as your default IP gateway so that any IP trafﬁc not intended for your corporate intranet will be directed to the ISP.

■ Associate your primary Domain Name Server with whichever

proﬁle is more accessable. If you choose for neither proﬁle to be “dial-on-demand”, you may associate a secondary DNS with the other proﬁle.

However, static routes are used only if they appear in the IP routing table, which contains all of the routes used by the Netopia ISDN Router (see “IP routing table” on

page 9-10).

Static routes are helpful in situations where a route to a network must be used and other means of ﬁnding the route are unavailable. For example, static routes are useful when you cannot rely on RIP.

■ To make sure that the static route is known only to the Netopia

ISDN Router, select Advertise Route Via RIP and toggle it to No. To allow other RIP-capable routers to know about the static

route, select Advertise Route Via RIP and toggle it to Yes. When Advertise Route Via RIP is toggled to Yes, a new item called RIP Metric appears below Advertise Route Via RIP . With RIP Metric, you determine the number of routers that RIP packets can traverse by setting a value from 1 to 15. Each RIP packet begins with the initial RIP Metric value, which is then incremented by one whenever the packet reaches a router. A router that receives a RIP packet with a RIP Metric value of 15 will not send that packet on to the next router. Therefore, the maximum number of routers that can be traversed is 15. Setting RIP Metric to 1 means that each RIP packet can reach 15 routers, while setting it to 15 means that each RIP packet can only reach the next router.

■ Select ADD STATIC ROUTE NOW to save the new static route,

or select CANCEL to discard it and return to the Static Routes screen.

Rules of static route installation

The Netopia ISDN Router applies certain rules before installing enabled static routes in the IP routing table. An enabled static route will not be installed in the IP routing table if any of the following conditions are true:

■ The static route’s Next Gateway IP Address matches the IP

address used by a connection proﬁle or the Netopia ISDN Router’s Ethernet port.

■ The static route’s Next Gateway IP Address matches an IP

address in the range of IP addresses being distributed by MacIP or DHCP.

■ The static route’s Next Gateway IP Address is determined to

be unreachable by the Netopia ISDN Router.

■ The static route’s route information conﬂicts with a connection

proﬁle’s route information.

■ The connection proﬁle associated with the static route is set for

dial-in connections only, and there is no incoming call connected to that connection proﬁle.

■ The connection proﬁle associated with the static route has a

disabled dial-on-demand setting, and there is no current connection using that connection proﬁle.

A static route is already installed in the IP routing table will be removed if any of the conditions listed above become true for that static route. However, an enabled static route is automatically reinstalled once the conditions listed above are no longer true for that static route.

Conﬁg.

IP Address Serving

• DHCP Setup

•BOOTP Setup

• MacIP Setup

In addition to being a router, the Netopia ISDN Router is also an IP address server. There are four protocols it can use to distribute IP addresses.

■ The ﬁrst, called Dynamic Host Conﬁguration Protocol (DHCP), is

widely supported on PC networks, as well as Apple Macintosh computers using Open Transport and computers using the UNIX operating system. Addresses assigned via DHCP are “leased” or allocated for a short period of time; if a lease is not renewed, the address becomes available for use by another computer. DHCP also allows most of the IP parameters for a computer to be conﬁgured by the DHCP server, simplifying setup of each machine.

■ The second, called BOOTP (also known as Bootstrap Protocol), is

the predecessor to DHCP and allows older IP hosts to obtain most of the information that a DHCP client would obtain. However, in contrast, BOOTP address assignments are “permanent” since there is no lease renewal mechanism in BOOTP.

■ The third protocol, called IPCP, is part of the PPP/MP suite of

wide area protocols used for ISDN WAN connections. It allows remote terminal adapters and NAT-enabled routers to be assigned a temporary IP address for the duration of their connection.

IP Setup 4-19

■ The fourth protocol, called MacIP, is used only for computers on

AppleTalk networks. MacIP provides a protocol translation (or gateway) function between IP and AppleTalk as well as an IP address assignment mechanism. Like DHCP, MacIP address assignments are normally temporary, although you may also use static IP addresses with MacIP.

Since no two hosts can use the same IP address at the same time, make sure that the addresses distributed by the Netopia ISDN Router, and those that are manually conﬁgured are not the same. Each method of distribution must have its own exclusive range of addresses to draw from.

To go to the IP Address Serving screen, select IP Address Serving in the Advanced Conﬁguration screen and press Return.

■ Select Number of Client IP Addresses and enter the total number

of contiguous IP addresses that the Netopia ISDN Router will distribute to the client machines on your local area network.

■ In the screen example shown above, ﬁve Client IP addresses

have been allocated.

■ Select 1st Client Address and enter the ﬁrst client IP address

that you will allocate to your ﬁrst client machine. For instance, on your local area network you may ﬁrst want to ﬁgure out what machines are going to be allocated speciﬁc static IP addresses so that you can determine the pool of IP addresses that you will be serving addresses from via DHCP, BOOTP and or MacIP.

■ Example: Your ISP has given your Netopia ISDN Router the IP

address 192.168.6.137, with a subnet mask of

255.255.255.248. The subnet mask allocated will give you six IP addresses to use when connecting to the ISP over the Internet (for more information on understanding IP addressing refer to Appendix C). Your address range will be from .137-.143. In this example you would enter 192.168.6.138 as the 1st client address.

DHCP NetBIOS Options

If your network uses NetBIOS, you can enable the Netopia ISDN Router to use DHCP to distribute NetBIOS information.

NetBIOS stands for Network Basic Input/Output System. It is a layer of software originally developed by IBM and Sytek to link a network operating system with speciﬁc hardware. NetBIOS has been adopted as an industry standard. It offers LAN applications, a variety of “hooks” to carry out inter-application communications and data transfer. Essentially, NetBIOS is a way for application programs to talk to the network. To run an application that works with NetBIOS, a non-IBM network operating system or network interface card must offer a NetBIOS emulator. Many vendors either provide a version of NetBIOS to interface with their hardware or emulate its transport layer communications services in their network products. A NetBIOS emulator is a program provided by NetWare clients that allow workstations to run applications that support IBM’s NetBIOS calls.

MacIP (Kip Forwarding) Options

When hosts using AppleTalk (typically those using LocalTalk) arenot directly connected to an IP network (usually an ethernet), they must use a MacIP (AppleTalk-IP) gateway. Such a service is provided by AppleTalk models of the Netopia ISDN Routers. A MacIP gateway converts network trafﬁc into the correct format for AppleTalk or IP, depending on the trafﬁc’s destination. The MacIP gateway can also distribute IP addresses to AppleTalk computers on the network.

Note: Macintosh computers that have LocalTalk or EtherTalk selected in the MacTCP control panel, or “AppleTalk (MacIP)” selected in the TCP/IP control panel, must use the MacIP gateway to communicate with the Internet or any other IP network. Users should point their MacTCP or TCP/IP control panel to look in the LocalTalk zone for the MacIP server. Macintosh computers that have Ethernet selected in the MacTCP or TCP/IP control panel can do their own AppleTalk-IP conversions.

Setting up MacIP involves choosing MacIP dynamic address serving and then conﬁguring that type. KIP forwarding is simply a method for distributing IP addresses to AppleTalk clients.

IPX Setup

5-1

Internetwork Packet Exchange (IPX) is the network protocol used by Novell NetWare networks. This chapter shows you how to conﬁgure the Netopia ISDN Router for routing data using IPX. You also learn how to conﬁgure the router to serve IPX network addresses.

IPX Deﬁnitions

The Netopia ISDN Router supports the following IPX features:

■ IPX RIP and SAP

■ NetBIOS broadcast packet forwarding (IPX type 20)

■ IPX packet ﬁltering deﬁnable by source and destination IPX

address and socket number, for added security

■ IPX SAP ﬁltering to aid in optimizing WAN bandwidth

■ Dial-on-demand features:

■ Spooﬁng of IPX keep-alive, SPX, and server serialization

packets

■ Conﬁgurable RIP/SAP timers on connection proﬁles

This section deﬁnes IPX-related protocols such as RIP, SAP and NetBIOS, in addition to other related terms. See the next section for setup instructions.

5-2 Netopia ISDN Router Reference Guide

Internetwork Packet Exchange (IPX)

IPX is a datagram, connectionless protocol that Novell adapted from Xerox Network System’s (XNS) Internet Datagram Protocol (IDP). IPX is dynamically routed, and the routing architecture works by “learning” network addressing automatically.

IPX address

An IPX address consists of a network number, a node number , and a socket number. An IPX network number is composed of eight hexadecimal digits. The network number must be the same for all nodes on a particular physical network segment. The node number is composed of twelve hexadecimal digits and is usually the hardware address of the interface card. The node number must be unique inside the particular IPX network. Socket numbers correspond to the particular service being accessed.

Socket

A socket in IPX is the equivalent of a port in TCP/IP. Sockets route packets to different processes within a single node. Novell has reserved several sockets for use in the NetWare environment:

Field Value Packet Type Description

00h Unknown Packet Type Used for all packets not

classiﬁed by any other type

04h Service Advertising

Packet 05h Sequenced Packet Used for SPX packets 11h NetWare Core Protocol

Packet 14h Propagated Packet Used for Novell NetBIOS

Unused for RIP packets

IPX Setup 5-3

Routing Information Protocol (RIP)

RIP, which was also derived from XNS, is a protocol that allows for the bidirectional transfer of routing tables and provides timing information (ticks), so that the fastest route to a destination can be determined. IPX routers use RIP to create and dynamically maintain which are databases of internetwork routing information. See the last section in this chapter for more information on routing tables.

Service Advertising Protocol (SAP)

SAP is a protocol that provides servers and routers with a method to exchange service information. Using SAP , servers advertise their services and addresses. Routers collect this information to dynamically update their routing tables and share it with other routers. These broadcasts keep all routers on the internetwork synchronized and provide real-time information on accessible servers on the internetwork.

The following is a list of SAP server types:

Unknown 0000h Print Queue 0003h File Server 0004h Job Server 0005h Print Server 0007h Archive Server 0009h Remote Bridge Server 0024h Advertising Print Server 0047h Reserved Up To 8000h

5-4 Netopia ISDN Router Reference Guide

NetBIOS

NetBIOS is a protocol that performs tasks related to the Transport and Session layers of the OSI model. It can operate over IPX, using a special broadcast packet known as “IPX Packet type 20” to communicate with IPX NetBIOS servers.

IPX Spooﬁng

The Netopia has several IPX features designed to restrict the trafﬁc on the ISDN link when the unit is not sending or receiving IPX data. When the link is idle and a user is logged into a Novell server, the server will send “keep alive” packets to ensure the user is still there. If the link is idle, the “keep alive” packets will be sent back to the server by the locally connected Netopia router as though they came back from the user without bringing up the ISDN link.

Main Menu

Similarly, “SPX keep alive” packets are treated in this manner. IPX RIP, and SAP messages will not be sent if the link is down. Together these features enable the user to remain connected to a Novell server or SPX peer without bringing up the ISDN link, except to send and receive actual user data.
