Other
important tips
v Your computer modem might use only an analog telephone network, or
public-switched telephone network (PSTN). Do not connect the modem to a
PBX (private branch exchange) or any other digital telephone extension line
because this could damage your modem. Analog phone lines are often used
in homes, while digital phone lines are often used in hotels or office
buildings. If you are not sure which kind of phone line you are using,
contact your telephone company.
v Your computer might have both an Ethernet connector and a modem
connector. If so, be sure to connect your communication cable to the correct
one, so your connector is not damaged.
