Modem Cable

Your notebook has an RJ-11 (modem) jack and an internal modem. A modem cable with a 6-pin RJ-11 connector at each end is included with all notebook models.

If you purchased your notebook in a country where RJ-11 jacks are not standard, a country-specific modem adapter is also included. The adapter enables you to connect your modem to the type of telephone jack that is standard in your country.

ÄCAUTION: To prevent permanent damage to the modem, do not connect the modem to a digital line. If you accidentally connect the modem cable to a digital line, immediately disconnect the cable.

Your modem cable must be connected to an analog, not a digital, telephone line. Most home telephone lines are analog. Jacks for most PBX systems are digital. Some digital PBX jacks resemble analog jacks, but they are not compatible with the modem.

Some modem cables include noise suppression circuitry, as shown in the following illustration.
