Should You Connect via Ethernet or USB?

The USRobotics ADSL USB/Ethernet Modem gives you the option to connect through a USB or an Ethernet port. Selecting how to connect your modem is mostly a matter of preference and also depends on what ports are available on your computer.

Windows Installation

Step 1. Connect Microfilters (If Necessary)

If there are no microfilters included in your package and your ISP did not provide any, skip to Step 2 of these installation instructions.

If microfilters are required, install one on each telephone device (telephones, answering machines, and fax machines) that shares the same phone line as the ADSL signal.

A microfilter is a small device used to lessen the amount of interference between ADSL signals and telephone signals. Microfilters only need to be used if the ADSL modem and a telephone device are sharing the same phone line. If microfilters are not used, you may experience background noise on your telephone while data is being transmitted. Data transmissions may experience interruption by telephone calls if a microfilter is not used.

Connect Microfilters to Telephone Devices

To install the microfilter, plug the phone into the microfilter, and then plug the microfilter into the telephone wall jack. Do not install a microfilter on the cable that connects your modem to the telephone jack unless your microfilter has a connection for both the telephone and the ADSL device.

4. A prompt will display to remind you to plug in the USB cable when the computer restarts; click OK.

5. Once the modem has been installed, you will need to restart your computer; click Restart.

Step 2: Connecting the Cables

Connect the USB Cable

1. Plug the flat end of the provided USB cable into an available USB port on your Macintosh.
2. Plug the square end of the USB cable into the port of the modem labeled USB.

Connect the Telephone Cable

1. Plug one end of the provided RJ-11 telephone cable into the telephone jack or the ADSL splitter box provided by your Internet Service Provider.
2. Plug the other end of the RJ-11 telephone cable into the ADSL port of the USRobotics SureConnect ADSL USB/Ethernet Modem.

Once you have connected both the USB and the RJ-11, your Macintosh will detect the modem and load the installed software. This will enable you to use your new high-speed USRobotics SureConnect ADSL USB/Ethernet Modem.

Step 3: Configuring the Modem

In most cases, you will not have to change the ADSL-specific configuration parameters for your modem. Your ISP will have customized the software so that the modem installs with the defaults required for connecting to their own equipment. If the ADSL parameters need to be changed, they can be changed on the Configuration page of USRobotics Monitor.

USRobotics Monitor

Each parameter setting is specific to your ISP's network configuration; therefore, either keep the default settings or obtain alternate settings from your ISP. The settings that can be changed on the Configuration page of USRobotics Monitor are:

• ATM Channel VPI
• ATM Channel VCI
• Encapsulation Type
• ADSL Standard

1. To access the USRobotics Monitor, go to the Desktop and double-click the USR ADSL Modem icon.
2. The USRobotics Monitor will display; click the Configuration tab.

The value that you choose for Encapsulation Type will determine whether your modem is exposed to the operating system as a network-type device or as a modem-type device. The choices that begin with PPP will cause the operating system to view your modem as a modem-type device, and the remaining options will cause the operating system to view your modem as an Ethernet-type device.

NOTE: If you change any settings on the Configuration page of the USRobotics Monitor, click Save Changes. You must then restart the computer to apply the changes.

Step 4: Configuring the Operating System

Once the modem has been properly configured, the Macintosh OS 8.6 -9.X operating system must also be configured so that it knows how to properly communicate with your modem's software. You should configure the system software based on whether your ISP expects your modem to communicate as an Ethernet device or as a "regular" modem.

The Encapsulation Type you selected will dictate which components need to be configured. Use the table below to help you identify which components you will need to configure, and how you will need to configure them, depending on your Encapsulation and Connection Type.

Configuring TCP/IP

The most commonly used language, or protocol, used to communicate over the Internet is called TCP/IP (Transmission Control Protocol / Internet Protocol).

1. Go to the Control Panels submenu of the Apple menu. Click TCP/IP in the menu to display the Connect Via pull-down menu. The TCP/IP screen will display.
2. From the Connect Via pull-down menu, click ADSL USB Modem for Ethernet Mode, or select PPP for Modem Mode. Most ISPs will offer DHCP (Dynamic Host Configuration Protocol) as their IP Address. DHCP will automatically set up the proper IP Address when your connection is established.
3. Select Using DHCP Server from the Configure pull-down menu for Ethernet Mode and Using PPP Server for PPP Mode. If your ISP requires you to use a specific IP address, select Manually from the Configure pull-down menu, and then enter the IP Address provided by your ISP.
4. Once you have selected the above options, close the window by clicking the small square in the upper-left corner, then click Save.

Remote Access

When the Macintosh operating system is configured for Modem mode, it actually views your ADSL modem as a "regular" modem. This does not affect the performance of your high-speed Internet connection; however, it does affect the way you configure the operating system to complete the connection setup. Because the operating system thinks that you have a "regular" modem attached to your computer, you must configure the Apple Remote Access Dialer application to connect to the Internet.

1. Go to the Control Panels submenu of the Apple menu.

2. Click the Remote Access icon on the Control Panels menu.

3. Click the Options button to access the Remote Access options dialog box. In the Options dialog box, click the Protocol tab and select the following Protocol options:

• Connect automatically when starting TCP/IP applications.
• Use TCP header compression

4. Click OK to save the options and return to the Remote Access Options dialog box.

5. With the current window open, go to the Remote Access menu located at the top of the screen and click Modem. You can only access this menu if you are in the Remote Access window. The Modem screen will display. Select the following options:

• Select ADSL USB Modem from the Connect Via: pull-down menu.
• Select ADSL USB Modem in the Modem: pull-down menu.
• Confirm the Sound option is set to On.
• Confirm the Dialing option is set to Tone.

NOTE: It is critical that these settings be correct in order for the USRobotics SureConnect ADSL USB/Ethernet Modem to work correctly.

Once you have selected the above options, close the window by clicking the small square in the upper-left corner, then click Save. This will return you to the Remote Access setup screen.

6. Enter the following information in the Remote Access screen:

• Select the Registered User option.
• Enter your user name and password as provided by your ISP.
• Enter a numeric value of "1" in the Number box. The driver does not dial the number "1," but the dialer needs to see a number there in order for the dialing process to work.

Once you have verified that all of the information is correct, click the square in the upper-left corner, then click Save to save the configuration.

Operating the Modem

Your system should now be ready to connect to the Internet. If you have not already done so, make sure that you have properly configured your ADSL settings and Macintosh system software.

Ethernet Mode

If you are configured to operate in Ethernet mode, you should already be connected to the Internet. Open your Web browser to confirm proper network operation.

Modem Mode - PPPoE or PPPoA

As mentioned previously, when configured to operate in Modem mode, the system software expects you to dial a phone number to connect to your Internet provider. Because you are connecting via ADSL, no dialing actually takes place; you just have to go through the steps of dialing to get connected to the Internet.

1. To connect to your ADSL provider, select Remote Access from the Control Panels menu. Your Remote Access parameters should have already been configured.
2. Complete any missing information on the main Remote Access setup page, then click the Connect button. The status portion of the window will give you feedback as to whether or not the connection is progressing successfully.
3. Once the status indicates that the connection is complete, you may proceed with opening your Web browser and surfing the Web!

Linux Installation (USB Only)

Step 1: Compile and Install the Modem Driver

The following installation supports the encapsulations listed below:

• RFC1483 (LAN driver)
• RFC2516 (PPP Over Ethernet)
• RFC2364 (PPP Over ATM)

The package that you have contains the driver source codes and some script files for compiling, installing, and using the USRobotics SureConnect ADSL USB Modem. The driver will be installed as an Ethernet driver and the interface name will be called ADIModem.

NOTE: This driver should work with 2.4.x and 2.5.x kernels with USB and hot plug support installed. For instance, it should work with other distributions of Linux, such as Red Hat 7.x, Mandrake 8.x, Suse 7.x, and Slackware 8.x.

1. Log on as root.
2. Create a new directory.
3. Copy the tarball file into the new directory (if you are using ADSL Annex A, which works over a standard telephone line, use the tarball file 9002_POTS.tgz. If you are using ADSL Annex B, which works over an ISDN line, use the tarball file 9002_ISDN.tgz.)
4. Unzip the tarball file.

The figure below shows how to create the USR_USB directory, and copy the file 9002_POTS.tgz into that directory from the CD-ROM drive and then unzip the file. This is assuming you have already mounted the CD-ROM into /mnt/cdrom directory.

The commands are as follows:

• cd /usr
• mkdir USR_USB
• cd USR_USB
• cp /mnt/cdrom/Linux/9002_POTS.tgz
• tar xvzf 9002_POTS.tgz

5. Run ./inst_mod KernelSrcDirectory. KernelSrcDirectory is the directory where this script can find the kernel source codes. This directory is normally under the /usr/src directory. If the kernel source code is not installed by default with your Linux distribution, you have to install it first. Refer to your distribution manuals for more information.

For instance, under RedHat 7.2, the source directory is /usr/src/linux-2.4.7-10, the install command is then:

USR_USB/./inst_mod linux-2.4.7-10

The following figure shows how to compile the driver under RedHat 7.2.

NOTE: DSP firmware files will be located in the /etc/analog directory. Each time you plug in in the USB cable, the kernel will call the application in /etc/hotplug/usb/adiusbadsl to set up your modem.

At this point, you have built the driver that supports RFC1483 (LAN) and also RFC2516 (PPPoE).

Step 2: Configuring the Modem Parameters

/etc/analog/adiusbadsl.conf

There are a number of parameters that the modem needs to have configured in order to initiate a connection when the USB cable is plugged in. These parameters are in a file called adiusbadsl.conf. In order for the modem to be operational, these values must be modified in the file using an editor such as pico, vi, or joe.

Setting the VPI/VCI and Encapsulation Type Parameters

VPI and VCI values are used to identify your Virtual Path Connection (VP) and your Virtual Circuit Connection (VC). Your ISP should have provided you with VPI, VCI, and Encapsulation-type parameters. The VPI/VCI values are in hexadecimal format, an example is below:

• VPI=00000008
• VCI=00000023

NOTE: Whenever you change anything in the adiusbadsl.conf file, unplug the USB cable from the modem, and then plug it back in. This will reset the modem to use the new values.

Encapsulation Type

Encapsulation is a technique used by layered protocols where the data set is wrapped in a protocol header. This technique helps to bridge different networks. When a protocol data unit (PDU) is sent, a layer will add header information to that unit from the layer above. For example, a packet contains a protocol header from the physical layer. Then the network layer (IP) adds a protocol header. Finally, the transport layer (TCP) adds a protocol header, followed by the application protocol data.

The encapsulation type depends on the type of interface your ISP provides to you. Your ISP should be able to provide you with the appropriate values for their system.

Example: Encapsulation = 00000006 (PPPoA-VC)

Step 3: Set Up the ADSL USB/Ethernet Modem for Use

PPPoE Interface

After completing the first two steps, you will have built the driver that supports RFC1483 (LAN) and also RFC2516 (PPPoE).

NOTE: Since this package supports PPPoE encapsulation, you can use any PPPoE client software that you choose. An example of a PPPoE client is Roaring Penguin, which you can get from http://www.roaring penguin.com. You will not need to change anything in the package to be able to use PPPoE. You will just need to install the LAN driver and the desired PPPoE client software.

As soon as you install the package on your system, you can connect the USRobotics SureConnect ADSL USB/Ethernet Modem to your computer using the included USB cable. Once the modem is connected, the driver and module will be loaded automatically.

When the modem is detected, the PWR LED on the front left panel of the modem, will begin to blink. The driver will create an Ethernet interface called ADIModem. Although the interface is created, it is not yet configured. To confirm the interface has been created, run the following command:

ifconfig -a

A list will display all interfaces on your system. Locate the ADIModem interface. Once the interface is located, you can configure it using either one of the following methods:

• DHCP
• Static IP Address

Configure Interface Using DHCP

1. Confirm that your server provides a DHCP server.
2. If it does, then run the following script:USR_USB/ADI_PPPOE/./godhcp
3. To confirm the interface is operational and it has an IP address assigned, run the following script:ifconfig

Configure Interface Using a Static IP Address

1. Run the following script to configure the interface using a Static IP Address:

• USR_USB/ADI_PPPOE/./gostatic ADIModem IPAddress Netmask
• route add default gw ipaddress (this is the gateway provided by your ISP)
• pico /etc/resolv.conf

• Run the following command to confirm the interface is operational and an IP address has been assigned: ifconfig

Once the interface is properly configured, you can start sending and receiving data.

NOTE: Whenever you unplug the USB cable, you need to run one of the above scripts. If you want to bring down the interface and bring it back up, run the USR_USB/ADI_PPPOE/./stopip. Use one of the above script files to configure the interface again.

PPPoA Interface

1. After you have built the driver, run the following script: USR_USB/./inst_pppoa

2. The script will compile, build, and install the PPPoA module. Upon completion, the script will copy the needed scripts and configuration files into the /usr/sbin and /etc/ppp directories.

3. If you are using ADSL Annex A, confirm that the VPI/VCI and Encapsulation type parameters located in the /etc/analog/usradslpots.conf are the same as the ones provided to you by your ISP. If you are using ADSL Annex B, which works over an ISDN line, confirm that the VPI/VCI and Encapsulation type parameters located in the /etc/analog/usradslisdn.conf are the same as the ones provided to you by your ISP.

4. Plug the USB cable into the modem and computer.

5. Modify the user name and password in pap-secrets, chap-secrets, and options files in /etc/ppp directory with the values provided by your ISP. For example, the format of the pap_secrets and chap_secrets files:

In the options file, you need to change the user "**********" with the username provided by your ISP.

6. Go into /usr/sbin directory and run the following script: ADI_PPP_Go

7. Once the script has completed, run ifconfig and confirm that you are connected to your provider. PPP will create an interface called "ppp0" whenever it connects to a server.

8. To disconnect from the server, run ADI_PPP_Stop at the same directory and PPP will disconnect from the server.

The graphic on the following page shows the USRobotics SureConnect ADSL USB/Ethernet Modem connected to an ISP. The ADIModem interface is loaded (local IP 192.168.60.30), and the ppp0 interface is up and running with an IP address (80.11.157.151) and a gateway (80.11.157.1).

Modem Status

To view various statistics about the modem and the connection, run the following script:

USR_USB/ADI_PPPOE/./showstat

The statistical information will be available through ADIModem in /proc directory.

This feature is available as soon as you plug the USB cable in.
