Multi-Tech Systems MT5634ZPW-PCI owner manual Troubleshooting

4 Troubleshooting

•If the modem reports BUSY, the other number may be busy, in which case you should try again later, or it may indicate that you have failed to add a 9, prefix to the phone number if you must dial 9 for an outside line.

If you must dial 9 to get an outside line, the easiest way to dial it automatically using legacy software is to include it in the modem’s dial prefix, e.g., ATDT9,. Note the comma, which inserts a pause before the number is dialed. For example, to change the dial prefix in MultiExpress Terminal, select Setup, Modem; then select the modem type you are using and type the new prefix in the Dial Prefix box. To change it for Windows 95 software, select Start, Settings, Control Panel, Modems. In the Modems Properties sheet, select the appropriate MultiModemZPW-PCI model number (e.g., Multi-Tech MT5634ZPW-PCI), click Dialing Properties, and type 9 in the local and long distance boxes in the “How I dial from this location” box.

•If the modem reports NO ANSWER, the other system has failed to answer, or you might have dialed a wrong number. Check the number.

•If the modem reports NO CARRIER, the phone was answered at the other end, but no connection was made. You might have dialed a wrong number, and a person answered instead of a computer, or you might have dialed the correct number but the other computer or software was turned off or faulty. Check the number and try again, or try calling another system to make sure your modem is working. Also, try calling the number on your telephone. If you hear harsh sounds, then another modem is answering the call, and the modems may be having problems negotiating because of modem incompatibilities or line noise. Try connecting at a lower speed by setting register S37 to a lower rate (e.g., by typing ATS37=11 in the terminal window and pressing ENTER) and then calling again.
