FEDERAL COMMUNICATIONS COMMISSION

RADIO FREQUENCY INTERFERENCE STATEMENT

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio or TV reception, which can be determined by turning the equipment off and on. The user is encouraged to try to correct the interference by one or more of the following measures:

Reorient or relocate the receiving antenna.

Increase the separation between the equipment and receiver.

Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

Consult the dealer or an experienced radio/TV technician for help.

Changes or modifications to this unit not expressly approved by ADTRAN will void the user's authority to operate the equipment.

CANADIAN EMISSIONS REQUIREMENTS

This digital apparatus does not exceed the Class B limits for radio noise emissions from digital apparatus as set out in the interference-causingequipment standard entitled "Digital Apparatus,"ICES-003of the Department of Communications.

Cet appareil nuerique respecte les limites de bruits radioelectriques applicables aux appareils numeriques de Class B prescrites dans la norme sur le materiel brouilleur: "Appareils Numeriques," NMB-003edictee par le ministre des Communications.

CANADIAN EQUIPMENT LIMITATIONS

Notice: The Canadian Industry and Science Canada label identifies certified equipment. This certification means that the equipment meets certain telecommunications network protective, operational, and safety requirements. The Department does not guarantee the equipment will operate to the user’s satisfaction.

Before installing this equipment, ensure that it is permissible to be connected to the facilities of the local telecommunications company. The equipment must also be installed using an acceptable method of connection. In some cases, the company’s inside wiring associated with a single-lineindividual service may be extended by means of a certified connector assembly (telephone extension cord). Compliance with the above conditions may not prevent degradation of service in some situations.

Repairs to certified equipment should be made by an authorized Canadian maintenance facility designated by the supplier. Any repairs or alterations made by the user to this equipment, or equipment malfunctions, may give the telecommunications company cause to request the user to disconnect the equipment.

Users should ensure for their own protection that the electrical ground connections of the power utility, telephone lines, and internal metallic water pipe system, if present, are connected together. This precaution may be particularly important in rural areas.

Users should not attempt to make such connections themselves, but should contact the appropriate electric inspection authority, or an electrician, as appropriate.

The Load Number (LN) assigned to each terminal device denotes the percentage of the total load to be connected to a telephone loop which is used by the device, to prevent overloading. The termination on a loop may consist of any combination of devices subject only to the requirement that the total of the Load Numbers of all devices does not exceed 100.

CONNECTING TO AN INTERNET SERVICE PROVIDER

Internet Access using Network Address Translation (NAT)

1.Connect the 10BaseT cable from the PC’s network card to the Express XL/ XLT. Select TO NIC on the Express XL/XLT back panel.

2.Go to the Configuration/Connection List menu, and then press the right arrow key to place the cursor on theNum column.

3.Type I to insert a new Connection List entry.

4.Using the arrow keys, move the cursor over the Num column for the inserted entry. PressEnter to place the subentries into the right pane.

5.Set the Description to an identifiable name (i.e., ISP).

6.Go into the Authentication field and selectPAP or CHAP for theTx Method.

7.Enter your user name and password (provided by your ISP) into the Tx Username andTx Password fields.

8.Move the cursor to the left pane and highlight the IP parameters.

9.Set the NAT item toYes. This is a very important step. The Express XL/ XLT will need to translate the “fake” IP address(es) on the PC(s) to the “real” address provided dynamically by the ISP. SeeIP/NAT on page 43 for more details.

10.All other IP parameters should be left at their default settings. Navigate over to the Dial Out parameters.

11.Enter the number into Number 1. If configured for twoB-channel(PPP Multilink) by the ISP, enterNumber 2 if it exists and setInitial Channels to2.

12.Arrow left until the message Save Connection List Changes appears. Typey to save.

13.Go to the Configuration/IP menu and enter an IP address and net mask into theIP Address andSubnet Mask fields. The factory default setting will work just as well (10.0.0.1, 255.255.255.0).

14.Go into the Configuration/IP/NATsubmenu and set DHCP Modeto On.

15.Arrow left to save the configuration.

16.Go into the Dial menu.

17.Set the cursor over the Dial parameter for the Connection List profile you just set up.

18.Press Enter; the Express XL/XLT will start dialing.

19.If the call is successful, the Status column will readactive. If not, make sure the number(s) are correct or referenceChapter 4 on page 107 (the troubleshooting chapter) before going on to the next step.

20.Once the call is up, the PC must generate a DHCP request to obtain the IP parameters needed to get on the Internet. Refer to your PC’s user manual or help screen.

MULTIPROTOCOL ROUTING BETWEEN TWO LANS

Remote/Home Office Accessing the Corporate LAN

The following steps can be used to set up the Express XL/XLT on a remote LAN to access a corporate or central LAN using demand dial and dynamic bandwidth management.

1.Connect the 10BaseT cable from the hub to the Express XL/XLT. Select TO HUB on the Express XL/XLT back panel. TheLI indicator should be illuminated.

2.Set the IP address andSubnet Mask assigned by the network administrator in theConfiguration/IP menu.

3.For the Default Gateway, enter the IP address of the access server at the remote site. This creates a default route in the IP routing table that will be used with thedial-on-demandfeature in the Express XL/XLT.

4.Use the arrow keys to get to the Configuration/IPX menu. Set theNetwork value to the IPX network supplied by the network administrator. Set theSeed Status toSeed. Arrow left and save the changes with ay when prompted.

5.Move to the Configuration/Connection List. Use the arrow keys to move the cursor over theNum column. TypeI to insert a new entry.

6.Move the cursor over the Description field and pressEnter. A pop up window appears in which to enter a name for this Connection List profile.

7.Move the cursor over the Authentication menu and pressReturn. This will place the authentication parameters into the right pane.

8.Enter the username and password under Tx Username andTx Password. These items should be provided by the administrator at the site being dialed.

9.Use the down arrow to display the IP menu parameters in the right pane.

10.Move the cursor over the Route menu and pressReturn.

11.Enter the IP address andNetmask parameters of the access server at the remote site. This creates a static route to the access server’s network which is entered into the Express XL/XLT’s IP route table.

12.Move the cursor over the RIP menu. Check with the network administrator for the type of routing protocol used. The Express XL/XLT supports RIP versions 1 and 2. The protocol is set in theProtocol parameter.

13.Select Yes for theTriggered parameter. This will prevent periodic RIP updates that keep the ISDN link from going “idle.”

14.Select Yes for theRetain parameter. This will allow the routes learned from the access server to be saved in the IP routing table. Access to any of those networks from the workstation will cause this profile to be dialed.

15.Use the left arrow to get back to the previous menu. Use the down arrow to view the IPX menu parameters in the right pane.

16.This is similar to steps 13 and 14. Select Yes forTriggered andYes forRetain. This will allow the ISDN link to go to an idle state and permit the Express XL/XLT to “spoof” the server information obtained from the access server. A similar configuration must be selected on the access server.

17.Use the arrows to get the Dial Out menu parameters for this profile.

18.Enter the phone number of the access server in Number 1. If configured by the administrator to use twoB-channelsusing Multilink PPP, set theInitial Channels field to2. Some PPP protocols, if they exist in the access server, will allow the second channel to come into play only if the bandwidth is needed. If this is the case, the Express XL/XLT will automatically negotiate this with the access server.

19.Now move to the Bandwidth menu for this profile. Once there, use the right arrow to move to theOn Demand submenu.

20.Set the Mode parameter toOn. This enables the dynamic bandwidth features of the Express XL/XLT.

21.Select the Idle Timeout parameter and enter the number of seconds the Express XL/XLT should wait before hanging up the connection when no traffic is present. A value of 120 seconds is typical. A value of 0 means never idle the link.

22.All the parameters for this Connection List profile are complete. To save them, press the left arrow to get to the top (main) menu; when prompted

Save Connection List changes? enter y.

23.Set up the computer workstation’s IP and IPX parameters as instructed by the network administrator. The Express XL/XLT’s IP address should be the computer’s default gateway.

When the computer which is attached to the local LAN attempts to access a host on the access server, the Express XL/XLT will dial the number provided in the Connection List profile. The Express XL/XLT will provide one of two B-channelsbased on traffic demand and POTS port usage (Express XLT model only). If no packet traffic is transmitted or received for the specified number of seconds, the Express XL/XLT will disconnect the link until a computer on the local LAN again attempts to access a host on the access server.

If Novell’s IPX protocol is being used, the link must be dialed first in the Dial menu to obtain the server and route information needed by the computer to boot up. Advanced users can use the Express XL/XLT’s Probe feature to periodically dial the access server to obtain the route and server information, thereby removing the need to manually dial the first time.
