10 Modem and Local Area Network

Modem

The modem in the computer must be connected to an analog telephone line using a 6-pin, RJ-11 modem cable. In some countries, a country-specific modem cable adapter is also required. Jacks for digital PBX systems may resemble analog telephone jacks, but they are not compatible with the modem.

WARNING! Connecting the internal analog modem to a digital line can permanently damage the modem. Immediately disconnect the modem cable if you accidentally connect it to a digital line.

If the modem cable contains noise suppression circuitry (1), which prevents interference from TV and radio reception, orient the circuitry end (2) of the cable toward the computer.

NOTE The computer may look different from the illustrations in this guide. The location of the modem jack varies by model.
