modem line input to a direct analog telephone line. This will maximize modem performance by avoiding any problems introduced by internal PBX systems, etc.
4 Installing the Modem on Windows 98SE, Millennium, Windows 2000 and Windows XP
(Note: The Install Wizard may vary slightly with different versions of the OS and different service packs) On starting Windows for the first time after installing the modem Plug and Play (PnP) detects the new hardware and begins an install wizard for the modem. The modem is detected as a new Hardware Communications Device or other similar name. The wizard first looks for the modem information (INF) file, which is included on Motorola's distribution disk or CD-ROM. This file contains information about the modem, including device type, device driver information, as well as the AT command/response sets that it supports. Browse to the SM56 modem files on the Motorola disk/CD-ROM. Windows will find the information on the disk. On older versions of Windows 98SE, you may get an error message Cannot Locate File...... If you get such message, simply re-point the install wizard to the Motorola disk/CD-ROM and it will find the file the second time around. Windows copies the necessary modem files to the computer and transparently runs the necessary installation routines. For D/F/TAM and D/F/TAM/Speakerphone modems, Windows finds a second device after the modem has been installed. Windows notifies you that it has found a Serial Wave Device for the modem and prompts for a Wave Device driver. Re-point to the Motorola disk/CD-ROM and click OK. It finds the INF file and installs the appropriate drivers. Note: The SM56 also installs a modem Helper utility on the Windows System Tray (right side of the Task Bar). This application includes real time modem status (dialing, negotiating, connect rate, etc.), in addition to user selection for COM port, country and language. There is also an audio test included, which allows you to verify if your sound subsystem supports Microsoft DirectX 5.0 (or later) -- needed to hear call progress (dialing and negotiation). The SM56 installation auto-detects the country from the OS and defaults to that.
If this happens, the modem software is properly installed and functioning correctly.
1. Open the Windows Control Panel and double click the Phone and Modems Options icon.
2. Select the Modems tab ,and single click the COM port that the Motorola SM56 modem uses 3. Click on the Properties button. 4. Select the Diagnostics tab. 5. Click the Query Modem button Within a few seconds a window will appear with the modem responses to various ATI commands issued to it. If this happens, the modem software is properly installed and functioning correctly.
Verifying Proper Hardware Operation To verify correct SM56 modem hardware operation, you can use the following local analog loopback (LAL) test procedure, as follows:
1. Important: Ensure that the telephone cable is securely connected at both ends.
2. Open HyperTerminal (or any terminal application). 3. Optionally, select a connection name and icon. 4. In the Connect Using window, select the Motorola SM56 ...... modem. Click OK. 5. Enter a number in the Phone Number box...any number since we will not be dialing it. Click OK. 6. On the next screen select Cancel. 7. Enter AT and hit <Enter>. 8. The response OK should appear. 9. Enter ATS46 = 23 and hit <Enter>. 10. Enter AT&T1 and hit <Enter>. Wait a few seconds. 11. Type some letters at the keyboard. If the hardware is functioning correctly, the letters you type appear on the screen. 12. To exit this test mode, type +++ in quick succession (note no carriage return) to escape to command mode. After getting the OK response type ATH <Enter> to hang up.
6 Troubleshooting
If there is a problem when using the SM56 modem, and your communications application does not explain the problem, check the following list of symptoms and tips.
Get An Error Message "Telephone signal not detected, please check connection "
1. Ensure that the telephone cable is securely connected at both ends. 2. Ensure the telephone cable is plugged into the correct jack on the modem -- some modems provide a second jack for handset support. 2. Unplug the telephone line cable from the computer, and connect it directly to a telephone from the wall outlet. Check for a dial tone. If there is none, the problem is in the telephone line or system. Call the service provider.
Get An Error Message Loop current too high, please close the application and check the telephone line connection
When you try to dial a connection an error message box pops up, indicating that you are not connected to a proper analog phone line. This is the SM56 digital line guard feature, which protects against hardware damage if the modem is plugged into a high current phone outlet -- such as a digital phone jack. The modem automatically detects the over-current and goes back on-hook before hardware damage occurs. Check the phone outlet and make sure that it is a real analog phone line. Try another analog phone jack.
Streaming applications like RealPlayer stop receiving data and report "Net Congestion"
1. This usually occurs when the ISP, Internet, or streaming host side server is busy and there are many users competing for bandwidth. It is not a modem problem.
You cannot enter tone selections successfully when calling tone-driven applications
When dialing a remote system that requires you to enter selections using the telephone keys, such as a voicemail depot or bank-account information provider, you can lengthen the duration of the tones your modem sends, so that the remote system can detect them better. To adjust DTMF tone length, use the AT+VTDn command, where n specifies the tone duration. Check the SM56 online Help (via the SM56 Helper application on the Windows Desktop Tray) for a list of supported AT Commands.
The modem responds to commands, but they do not appear on the screen
1. Usually this is because the local echo is turn OFF. Turn it on by issuing ATE1 and hit <Enter>.
You've installed a new peripheral device; now the modem does not work
1. 2. 3. 4. 5. In the Windows desktop tray, select Start. Select Help. The Windows Help Topics window appears. Select the Contents tab. Select If You Have a Hardware Conflict. A series of troubleshooting actions appears. Follow the appropriate sequence.
6. Check the Use Error Control-Required to Connect box. In Win2K/XP 1. Open the Control Panel. Double click the Phone and Modem Options icon. 2. Click on the Modems Tab 3. Click on the Motorola SM56...Modem 4. Click on Properties. 5. Click on Advanced. 6. Click on Change Default Preferences 6. Select Standard EC from Data Protocol drop down menu.
8. Follow the prompts and point to the location where you have stored the latest driver. 9. Select Yes when asked to reboot the system.
If you upgrade from an OS to another, which uses the same driver, the SM56 will continue to function as before. No new drivers are required. However if you upgrade to an OS with a different set of drivers, you must get a new set of drivers for that operating system. Contact your SM56 modem supplier for driver status and updates. Therefore, if you change from Windows 95/98FE to Windows 2000 and XP you must get a new set of drivers for that operating system.
hardware on the modem board (i.e. instead of voice codec and speaker and microphone jacks on the modem board). The following sound system tuning can be done via the Windows Master Volume control -- double click the speaker icon in the Windows system tray. Please be aware that different sound systems have different configuration options, so not all volume and recording windows look the same or provide you with the same options. Or indeed some of the window and control names can be different. Master Volume Control (Playback/Speaker) All balances should be muted except for the "Wave Balance" and the "Volume Control Balance". Recording Control (Recording/Microphone) The only balance selected should be the "Mic Balance". All the other should not be selected or muted depending on the selections given (somewhat sound system dependent). To be sure, it is also recommended to keep the levels of the unselected balances in the recording control window to minimum setting. Also in case the Microphone gain is too low (rarely) then you can always boost it up by a multiple of 10dB by going to "Options" and to "Advanced Controls" and clicking on the "Advanced" icon. In the "Advanced Controls for Mic" window check the boost box and close the window to boost the microphone level. Conversely, if the gain of the microphone is too high and you talk too close to the microphone, then the voice will be saturated and noisy. If this is the case deselect the "Mic Boost" check box.
