North American FCC and telephone company requirements
If your IBM 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, see page 7-5 “Opening the system unit” to open the unit to get the
FCC registration number on the modem card.Provide this information to your
telephone 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
determine 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 may notify
you in advance; if advance notice isn't practical, you will be notified as soon as
possible. You may be advised of your right to file a complaint with the FCC.
4. Your telephone company may make changes in its facilities, equipment, opera-
tions, or procedures that could affect the proper operation of your equipment. If
they do, you may be given advance notice so as to give you an opportunity to
maintain uninterrupted service.
5. If you experience trouble with this built-in modem, contact your Authorized
Seller, or the IBM HelpCenter-PC, IBM Corporation, 3039 Cornwallis Rd., Bldg,
203, Research Triangle Park, NC 27709-2195 1-919-517-2800, for repair/
warranty information. The telephone company may ask you to disconnect this
equipment from the network until the problem has been corrected, or until you
are sure the equipment is not malfunctioning.
6. No customer repairs are possible to the modem.
