Zoom 1120, 2925 quick start Problem Your modem does not make a connection

Problem: Your modem disconnects while communicat- ing with a remote system.

Solution: The remote system has hung up, and you need to reconnect. The other most common sources of interruptions are Call Waiting or someone picking up an extension phone.

If you have Call Waiting, you can usually tem- porarily disable it by including *70, (including the comma), or by selecting it as a prefix, in the software’s dialing directory.

You cannot disable Call Waiting for incoming calls. If your incoming data calls are frequently disrupted by Call Waiting, you should consider dropping the service or installing a separate phone line without Call Waiting.

Problem: Your modem does not make a connection.

Solution: If your modem places calls but never connects, make sure you are dialing the right number and that the remote modem is turned on.

Problem: You receive bursts of errors occasionally, but otherwise data quality is good.

Solution: The connection may have been established on poor-quality or noisy telephone lines. Hang up and place the call again to try to obtain a better connection.

Someone may be picking up an extension con- nected to the line that your modem is using. If your modem is sharing a telephone line with other telephones, inform the other users when you will be making a data call, or install a separate line dedicated to data calls.

Your telephone line may have a Call Waiting feature and a call is being received. See the Call Waiting discussion on page 27.

Problem: Random errors occur or data is missing in transmitted data.

Solution: Use the MNP or V.42 protocol if the remote mo- dem supports one of these protocols. See the table on page 26 for more information.

Select a lower baud rate in your communica- tions software and place the call again.
