Introduction Thank you for purchasing the Actiontec 56K ISA Advantage V.90 internal modem. The Advantage incorporates the latest technology in host-based V.90 modems. This new technology provides vast improvements in both the performance and the capabilities of personal computer fax/modems. Controller-less modems, also known as Win Modems or Windows Modems, utilize your computer’s Central Processing Unit (or CPU) to perform some of their functions.
Do This First Please read the following tips before attempting to install your new modem. For Windows 95 and Windows 98 Installations Be sure to remove all other modem drivers from your operating system. To do this, right-click My Computer, choose Properties from the menu that appears, then click on the Device Manager tab. Double-click the Modems icon in the list of devices to show the modems installed. Click once on the icon next to any modems in this list to select them.
If you are going to use the Telephone Answering Machine (TAM) functions of the modem and you are running Windows 95, you need to install a software component called Unimodem V. If you have Windows 95 OEM Service Release 2 (Version 4.00.950 B) or a later version of Windows, this component comes standard as part of the operating system. To find out which version of Windows 95 you are using, right click the My Computer icon on the desktop, and choose Properties from the menu that appears.
To disable COM2, boot your system and enter your BIOS setup. You can normally invoke the BIOS setup menu by pressing a key or a combination of keys at the first boot up screen. Some of the common keys are DELETE, F1, F2, CTRL+ALT+S, CTRL+ALT+ESC. (Watch the text that appears as you turn your computer on-there will probably be instructions on how to enter “SETUP”--following these instructions will give you access to the BIOS.
Figure 3b: Windows 95 (or 95A) COM2 Disable Panel Proceed to the section titled “Installing the Modem.” For Windows NT 4.0 Installation Remove all other modem drivers from your operating system. On the Start menu, click Settings then click Control Panel. In Control Panel, double-click on the Modems icon. Select the modem you wish to remove and click Remove. Turn off the computer and physically remove the modem from your system. Do not install your new modem at this time. Follow the procedures below.
Before installing the modem, you must enable ISA Plug-N-Play support within Windows NT. First set your system BIOS to “PnP OS” and then insert the Windows NT 4.0 CD-ROM into your systems CD-ROM Drive. The Startup window for Windows NT 4.0 should appear after a few moments. Click Browse This CD. Doubleclick the Drvlib folder. From the new panel double-click on the Pnpisa folder. Another panel will appear. Double-click on the x86 folder. The contents of this folder should contain a file labeled Pnpisa.
Installing The Modem Always discharge static electricity before handling your modem. You may discharge static electricity by touching a grounded metal structure or by using any commercially available grounding strap. Make sure the expansion slot type is 16-bit, which has two slots to fit the ISA card. 8-bit slots have only one connector. If you use an 8-bit slot, the modem will not have access to the higher interrupts (IRQ 9-12).
5. Firmly, but gently, insert the modem into the available 16-bit expansion slot. Ensure that the card is seated properly before securing it with the screw removed in Step 4, as shown in the following diagram: Figure 6: Installing The Modem 6. Put the chassis cover back on the computer. 7. Be sure that all power switches are in the OFF position, then reconnect the power cables to the computer and its peripherals. 8. Connect the telephone line cable to the “Line (Telco)” jack as shown in Figure 7. 9.
Connecting Devices To The Modem Fig.7: Connecting Devices On the rear panel of your modem are input jacks to connect devices to the modem. As shown in the diagram, there are jacks for connection to a “phone” and to a phone “line.” The connector labeled Line (Telco) is meant to be connected to a standard analog phone line. To help reduce the load on your phone line, it is recommended that the modem be the only device connected.

Installing and Configuring Communications Software If your modem came with a communications software package, it is strongly recommended that you use this software for your modem. It’s default installation parameters have been specially configured to work with this modem. The Users Guide for this program can be found inside the modem package. It can be supplied in either soft-bound copy or on CD-ROM (depending on the model you purchased). Some configurations are packaged without communications software.
call is detected. The modem converts the digital information contained in the .wav file into an audio signal which is then sent over the phone line. The person calling hears your outgoing message and responds with an incoming message. The sequence of recording an incoming message is the reverse of an outgoing message. The modem converts the audio signal into a digital format and sends it to the application program. The application program then formats and stores the incoming message as a .wav file.
Troubleshooting This section lists some common problems and offers suggestions for a solution. It is important to remember that this modem is a Windows 95/98/NT based modem and requires 32bit virtual device drivers. It therefore cannot work in Windows 3.1 which cannot use these drivers. The modem also cannot work in DOS regardless of version. It is a purely Plug-N-Play device and has no provisions for manual configuration.
Device Usage box and make sure “Disable in this hardware profile” is not selected. (Windows 95 OEM SR2 and Windows 98 only). Make a note of the COM port and IRQ the modem is using. Errors reported in the Device Status box generally refer to conflicts. Click the Resources tab and read the “Conflicting Device List.” If a conflict is present, click to deselect “Use automatic Setting” and select a configuration that does not cause conflicts. Manually change the address and IRQ settings if needed.
If you receive an error message or the panel is blank, go to the section of this manual “Does Not Install.” Step 4: Does Not Install The most likely reason for a non-installation in Windows 95 or 98 is a lack of IRQ resources. The modem needs one IRQ and one COM Port in order to function. Computers are usually equipped with a sound card, CD-ROM drive, Hard-drive, floppy drive, video card, two COM ports, one LPT port, keyboard, and a mouse.
Modems section after you have deleted it from the Device Manager. If it is, this could be a sign that your Plug-N-Play settings are not correct. See “Does Not Install” for information about Plug-N-Play.) 3. Close all open programs and return to the Windows desktop. On the Start menu, click Find, then click Files or Folders and search for the files listed below. Type in the name and extension of each and click Find.
At the Advanced settings window, type the following in the “Containing text” field: LT Win Modem. Click Find Now. When a file is found, it will have the name “oem#.inf.” Delete only an oem inf file. To delete a file, highlight the file name by clicking once and then choose Delete from the File menu. After the file is deleted, you now need to find the other inf file. Go to the Advanced tab and type “LT_Win_Modem” in the “Containing text” field: After Windows finds the other file, delete it as before.
Common Problems No Dialtone Error Make sure you have connected the phone cable into the right connector on the back of the modem. See “Figure 7: Connecting Devices.” You may have too many devices connected to the phone line. Remove all other equipment. Your modem may not recognize overseas dialtone. Use the AT command string “ATX0” to have the modem ignore the dialtone before dialing.
when the modem is in use. This includes extension phones, answering machines, cordless phone bases, caller ID boxes and their cables. This reduces the load on your phone line and keeps signal attenuation to a minimum. Keep the length of your phone line cable to 10 feet or less. If necessary, move the computer closer to the phone socket. Don’t lay your cabling close to an electrical appliance like a refrigerator or air conditioner unit.
