Troubleshooting B-5
The modem cannot connect to the Internet at 56,000 bps.
This may be due to line conditions in your area. Due to FCC regulations and/or line conditions, it is not
always possible to achieve the maximum data rate.
To solve this problem:
Try moving the telephone line away from any power source, monitor, printer or computer cable.
The modem or communications software fails to detect that the remote user has hung up.
The modem or communications software relies on the dial tone, busy tone or silence period to detect that
a remote user has hung up.
This detection may fail due to one of the following reasons:
• Your local telephone system does not generate the dial or busy tone when the remote user hangs up.
• The silent period for the modem or communications software to detect that the remote user has hung
up is not long enough.
• The modem or communications software cannot detect a different dial or busy tone. For example, if
you are connecting to a PABX system, the dial or busy tone generated is different from the usual dial
or busy tone.
To solve this problem:
Prompt the remote user to respond. This may, however, result in a long delay before the communications
software responds to the remote user hanging up. To minimise this delay, modify the following settings:
• Voice message recording time.
• Number of prompts.
• Time to wait for a response after prompting.
No dial tone when using the modem.
The IRQ of the modem is either in conflict with another device or is mis-reported in Windows.
To solve this problem:
Many chipsets have IRQ routing drivers for Windows. If you have an internal modem, and these drivers
do not work or do not exist on your system, changing the slot of the modem card may help.
