Modem Notices
FCC Regulations - Part 68
To comply with the Federal Communications Commission (FCC) Rules and Regulations,
Part 68, these instructions must be followed:
1. Your modem must not be connected to a party line or coin-operated telephone.
2. If a problem occurs on the telephone line, your modem must be disconnected from the
telephone line until it has been determined that your modem is not the cause of the
problem.
3. All repairs to your modem must be made by Xircom, Inc. Unauthorized or unorthodox
repair methods can alter the modem’s radio frequency emissions and other
characteristics sufficiently to void your authority to operate the modem over a public
telephone network.
4. If requested, you must be prepared to provide the telephone company with the
following information:
Equipment Manufacturer: Xircom, Inc.
2300 Corporate Center Drive
Thousand Oaks, CA 91320-1420
U.S.A.
Model: CEM56-100
FCC Registration No.: 2U6USA-31569-M5-E
Ringer Equivalency No.: 0.7B
FCC Rules and Regulations - Part 68
This equipment complies with Part 68 of the FCC Rules. On the back of the CreditCard
Ethernet 10/100+Modem 56 is a label that contains, among other information, the FCC
Registration Number and Ringer Equivalency Number (REN) for this equipment. You must,
upon request, provide this information to your telephone company.
The REN is useful to determine the quantity of devices you may connect to your telephone
line and still have all those devices ring when your telephone number is called. In most but
not all areas, the sum of the RENs of all devices connected to one line 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 contact your local telephone company to determine the
maximum REN for your calling area.
