Page 20: Choose A Connection Protocol
ISDN channel usage The following diagram shows all the potential connections a DIVA LAN ISDN Modem could make, if it was configured to support an Internet connection, a corporate network connection, incoming data calls, and analog calls on both PHONE ports.
Page 21: Choosing A Connection Protocol
Choosing a connection protocol Since the DIVA LAN ISDN Modem supports so many potential connections, a set of rules is needed to control how the two ISDN B-channels are shared between connections. These rules are based on the type of connection protocol you decide to use for your data traffic.
Page 22: Summary
Compuserve offers access to their network over ISDN, using the V.120 protocol. V.120 operates on a single ISDN B-channel. Since two B-channels are available, the DIVA LAN ISDN Modem can support two V.120 connections at the same time. In general, you should use V.120 only when the site you are connecting to requires it.
Page 23: Order An Isdn Line
Find out if your ISDN line supports AutoSPID. AutoSPID is a new National ISDN protocol feature that enables the DIVA LAN ISDN Modem to automatically configure all parameters for your ISDN line. However, even if your ISDN line supports AutoSPID, it is a good idea to write down your SPIDs.
Page 24: Gather Internet Account Information
5. Gather Internet account information Description This is the phone number the DIVA LAN ISDN Modem dials to access the ISP. Some ISPs will give you two phone numbers—one for each ISDN channel. Your ISP may also have a backup number for each channel in case the primary number is busy or unavailable.
Page 25 To successfully log on to your ISP, you will need to define a script to automatically execute the log on process for you. The DIVA LAN ISDN Modem contains a pre-defined script that should work in the majority of cases.

ISDN billing practices vary from flat-rate monthly services to per-call billing to per-minute usage fees. To help you reduce your ISDN charges, the DIVA LAN ISDN Modem provides you with several cost-cutting configuration options. Use this chapter to find the best options for use on your ISDN line.
Page 59: The Cost Control Page
Each profile has its own idle timer. The idle timer controls how long a data call stays connected when no traffic is being sent or received. When the idle timer expires, the DIVA LAN ISDN Modem disconnects the call at the end of the next billing interval.
Page 60: Data Call Thresholds
Range: 0 (disabled) to 1000 If a profile exceeds either limit, all profiles are disabled. You must reset the DIVA LAN ISDN Modem to re-activate the profiles (or dial them manually to connect). Doing either also resets the threshold interval. (To determine if a profile has been disabled, click Connection Profiles on the Configuration main menu.)
Page 61: Configuring Bacp
The bandwidth allocation protocol (BACP) works in conjunction with the MLPPP connection protocol to regulate usage of your ISDN line. The DIVA LAN ISDN Modem uses BACP to monitor incoming and outgoing traffic, and to open or close the second ISDN B-channel as the traffic volume warrants. This reduces your communications charges by ensuring that two ISDN channels are never active when one is sufficient.

Page 68: Spoofing Netbios Services
The DIVA LAN ISDN Modem provides several options that let you choose the level of NetBIOS support you want to maintain. • All: The DIVA LAN ISDN Modem forwards all NetBIOS traffic to the remote site. No cost savings is achieved.
Page 69: Data Compression
Therefore, you should determine if the traffic on your link is suitable for compression before you enable it. The compression algorithm used is automatically negotiated by the DIVA LAN ISDN Modem and the remote site when the connection is established. The DIVA LAN ISDN Modem supports most popular compression standards, including: Ascend, MPPP, MS-STAC, STAC1, and STAC3.
Page 70: Manual Dialing
Each profile can be configured to use manual dialing only. If you enable this option and password protect the DIVA LAN ISDN Modem, you effectively put ISDN access under direct manual control of authorized users. To enable manual dialing Click Connection Profiles on the Configuration main menu.

Page 76: System Password
It can happen that you might forget your system password. The only way to erase the system password is to reset the DIVA LAN ISDN Modem to its factory defaults. This also returns all configuration settings to their default values.
Page 77: Automatic Log Out
The DIVA LAN ISDN Modem applies an automatic time out to configuration sessions. When a configuration session is idle for more than the time out value, the DIVA LAN ISDN Modem automatically logs the user out. This reduces the risk of unauthorized persons taking advantage of a logged-in computer that has been left unattended.
Page 78: Network Address Translation
LAN. By default, no computer on the internal LAN is visible to the external network the DIVA LAN ISDN Modem is connected to. This applies to the Internet, as well as a corporate network. Computers on the internal network cannot act as FTP or web servers, nor can they share their drives using Windows Network Neighborhood.
Page 79 The DIVA LAN ISDN Modem forwards all web traffic to the appropriate computer on the internal LAN. Note Setting up a web server disables remote access (via the ISDN line) to the DIVA LAN ISDN Modem web interface. Local computers can still log in.
Page 80 • Server address: Enter the IP address of the computer that will act as the server. The server address must be on the same LAN as the DIVA LAN ISDN Modem (or must be reachable via the LAN). Click Save.
Page 81: Remote Management
This effectively blocks remote computers from using the web-based interface, as well as the CLI (via Telnet). This does not affect traffic on the local LAN created by the DIVA LAN ISDN Modem. Therefore, if the local LAN is connected to other networks, these computers will have access to the DIVA LAN ISDN Modem.
Page 82 Chapter Six: Security To enable remote management If you want to support remote configuration, you must enable the remote management option. This option can only be set with the web-based configuration interface. On the Manual Configuration menu, click System. Check the Enable remote management check box. Click Save.
Page 83: Incoming Data Calls
(as explained in the steps below). Note Since the DIVA LAN ISDN Modem checks the ISP profile first, if both profiles have the same remote user name, the incoming call will always connect with the ISP profile. Incoming data calls can only be received if there is an available B-channel. To keep a free channel, you must use PPP (or V.120) for your existing connection.
Page 84 The remote computer provides an IP address to the DIVA LAN ISDN Modem. The remote computer has no IP address and the DIVA LAN ISDN Modem is not configured to supply one. The DIVA LAN ISDN Modem has no IP address and the remote computer is not configured to supply one.

Page 86: Call Screening
Call screening enables you to accept or reject incoming data calls based on their phone number. This is an effective way to limit dial-in access to the DIVA LAN ISDN Modem to a small group of remote sites. To set up call screening On the Manual Configuration menu, click Incoming data calls.
Page 87: Call Authentication
Generally, authentication is one-way, with the caller getting validated. For example: • When the DIVA LAN ISDN Modem calls an ISP or a corporate network, it will be authenticated (i.e., it must supply a username and password to log on).
Page 88: Callback
Administrator specified With this option, the DIVA LAN ISDN Modem does not supply the server with a number to dial. Instead, the remote identifies the DIVA LAN ISDN Modem by its caller ID or information supplied during call authentication.
Page 89: Delay Before Host Calls Back
Timeout waiting for callback Sets the amount of time the DIVA LAN ISDN Modem waits for the server to call back. During this time, the DIVA LAN ISDN Modem may accept calls that are not from the callback server unless you use call authentication (set the always authenticate remote option as shown on page 87) to validate the incoming call.
Page 90: Manual Dialing
Chapter Six: Security Manual dialing The DIVA LAN ISDN Modem automatically establishes the ISDN link whenever there is outgoing data traffic. There may be certain situations where this is not desirable and you will want to have manual control of ISDN usage.

Page 119: Concurrent Internet And Intranet Connections
Defining routes If you have two active connections, it is important to define routes so that the DIVA LAN ISDN Modem can send data to the proper connection. In most cases, you will want to send certain specific traffic to your corporate network, and route all other traffic to the Internet.
Page 120: Ip Routes
The DIVA LAN ISDN Modem and IP addresses The DIVA LAN ISDN Modem can have up to three IP addresses assigned to it. One address in used on the internal LAN it creates. The other two are used to communicate externally with remote sites.
Page 121 Note that the DIVA LAN ISDN Modem has its own address on the LAN: 192.168.1.1 External addresses When the DIVA LAN ISDN Modem establishes a connection to a remote site, it needs to be identified with an IP address. This address is associated with the profile making the connection. Since, two profiles are supported, two IP addresses are required.
Page 122 Ethernet LINK E4/C DIVA LAN ISDN Modem This example shows three addresses assigned to the DIVA LAN ISDN Modem: one on the LAN, one for an Internet connection, and one for a connection to a corporate network. 192.168.1.2 ISP profile Address dynamically assigned by ISP 222.182.22.39...
Page 123: Why Routes Are Needed
If you want to route all data to the corporate network, specify a single route using the special address 0.0.0.0. There can be only one default route on the DIVA LAN ISDN Modem. The default route always uses the special address 0.0.0.0.
Page 124: Multiple Connections
Consider the following scenario, which features an Internet and Corporate connection, each using one B-channel (PPP): 192.168.1.4 192.168.1.5 192.168.1.1 DIVA LAN ISDN Modem ISDN LINK DIVA LAN ISDN Modem Routes Route 1 = 0.0.0.0 with a mask of 0. Assigned to Internet connection.
Page 125 Routing on the local LAN The DIVA LAN ISDN Modem lets you create your own local area network. In some instances, this network, or the DIVA LAN ISDN Modem itself, will be connected to another network via a bridge or router. Consider this scenario, which adds another LAN to the previously discussed example: 150.150.5.2...
Page 126: The Routing Information Protocol (Rip)
The DIVA LAN ISDN Modem will listen for RIP broadcasts and define the needed routes. RIP also works on the local LAN created by the DIVA LAN ISDN Modem. If this LAN is connected to other LANs, RIP will discover the routes to these LANs (if they are configured to broadcast RIP routing information).
Page 127 If you select LAN, data is routed onto the local Ethernet LAN created by the DIVA LAN ISDN Modem. • Metric: Metric determines the weight of a route. If two identical routes exist, then the DIVA LAN ISDN Modem uses the route with the lower metric.
Page 128: Ip Filters
Each profile has its own filter stack. However, note that once any filter is activated, all incoming and outgoing data passes through the filter stack. By default, the DIVA LAN ISDN Modem defines three filters. This means, unless you turn these filters off, all incoming and outgoing data passes through the filter stack.
Page 129: Default Filters
Filters become active immediately after they are defined. You do not have to reset the DIVA LAN ISDN Modem to activate them. If you are defining a filter that affects your connection to the DIVA LAN ISDN Modem, you will lose contact immediately after saving.
Page 130 Click Filters to display the following page. (If you enabled remote management you will not see the first two filters.) Select the profile you want to define filters for. Click a “+” symbol to insert a new filter. The DIVA LAN ISDN Modem displays the Edit Filters page. IP filters...
Page 131 Only applies if you select the network or the host for location. Protocol IP datagrams can carry a wide variety of protocol traffic. The DIVA LAN ISDN Modem lets you filter the many of the most popular protocols. The following descriptions explain some of the options that are available.
Page 132: Ip Filtering Examples
• Telnet: If you filter all Telnet traffic, you will not be able to reach the command line interface (CLI). • TFTP: The DIVA LAN ISDN Modem can function as a TFTP server to support uploading and downloading of configuration files. If you filter TFTP traffic, you will not be able to use this feature.
Page 133 Allowing incoming traffic only from a specific network This example shows how to allow the DIVA LAN ISDN Modem to only receive incoming data from a specific network (112.111.212.0) on the Internet. Data from all other networks is dropped. However, outgoing traffic is not affected.
Page 134 When done, the filter stack should look like this: Blocking web surfing This example shows how to block computers on the local LAN created by the DIVA LAN ISDN Modem from surfing the web. Web traffic is carried by the HTTP protocol. Therefore, to stop web access, this protocol needs to be dropped for all outgoing traffic.
Page 135 Chapter Nine: Advanced Installations IP filters When done, the filter stack should look like this:...
Page 136: Making A V.120 Connection
• Configure the V.120 protocol for the profile that will make the connection. • Define a V.120 script to automatically log on to your ISP. The DIVA LAN ISDN Modem contains a pre-defined script that should work in the majority of cases. However, you may need to modify this script for your installation.
Page 137 Chapter Nine: Advanced Installations Click More. You will see the V.120 Dialing Script page: This page contains a pre-defined script that you can modify for your installation.
