Modem
The computer’s internal modem is connected to an analog
telephone line by means of 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 computer’s analog modem to a digital
line
can permanently damage the modem. Immediately disconnect your
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.
✎
Your computer may look different from the illustrations in
this guide. The location of the modem jack varies by model.
