Modem and Network Connections

Using the Modem

To connect the modem

CAUTION

Your built-in modem may not work with multiple phone lines or a private

 

branch exchange (PBX), cannot be connected to a coin-operated telephone, and

 

does not work with party lines. Some of these connections may result in excess

 

electrical voltage and could cause a malfunction in the internal modem. Check

 

your telephone line type prior to connecting your phone line.

 

 

Special restrictions in certain countries

Many countries impose a blackout period after a modem repeatedly fails to connect to a service provider. The number of failed attempts and the period you must wait before trying again differ from country to country. Check with your telephone company.

For example, if you are dialing from Italy and fail to connect to your server or cancel the connection, you must wait one minute before dialing that number again. If you dial before then, you will get an error message that says “delay.” After the fourth failed connection, you must wait one hour before trying the number again. If you dial before the hour is up, you will get a message that says “black list.”

When using a modem, an external surge protector can prevent damage to your notebook from lightning or other electrical surges. Connect any approved surge protector to the modem cable when you are using the modem.
