Modem regulations
FCC and telephone company
requirements
If your IBM Aptiva Personal Computer comes with a modem
already installed, the following Federal Communications
Commission (FCC) and telephone company requirements
apply:
1. The modem adapter card is located in the back of the
system unit. It complies with Part 68 of the FCC rules. A
label is affixed to the built-in modem that contains, among
other things, the FCC registration number, USOC, and
Ringer Equivalency Number (REN) for this equipment. If
these numbers are requested, slide the top cover forward
to see the label, and provide this information to your tele-
phone company.
2. The REN is useful to determine the quantity of devices you
may connect to your telephone line and still have those
devices ring when your number is called. In most, but not
all areas, the sum of the RENs of all devices should not
exceed five (5.0). To be certain of the number of devices
you may connect to your line, as determined by the REN,
you should call your local telephone company to deter-
mine the maximum REN for your calling area.
3. If the built-in modem causes harm to the telephone
network, the telephone company may discontinue your
service temporarily. If possible, they will notify you in
advance; if advance notice isn't practical, you will be noti-
fied as soon as possible. You will be advised of your right
to file a complaint with the FCC.

ties, equipment, operations, or procedures that could
