United States – Notice to Users of the Telephone Network

1. This equipment complies with Part 68 of the FCC rules. On the equipment is a label

that contains, among other information, the FCC registration number and ringer
equivalence number (REN) for this equipment. The label is located on the bottom
of your modem.

2. The 3825

Plus

 modem connects to the Public Switched Telephone Network (PSTN)

using the Universal Service Order Code (USOC) for Permissive mode, RJ11C. An
RJ14C jack must be used to connect a two-line telephone to the modem. The
Canadian equivalent to RJ11C is CA11A and the Canadian equivalent to RJ14C is
CA14A. For connection to an analog private line, an adapter cable should be used
to facilitate connection to a JM8 jack. The Canadian equivalent is CA40A.

3. The Ringer Equivalence (REN) is used to determine the quantity of devices which

may be connected to the telephone line. Excessive RENs on the telephone line
may result in the devices not ringing in response to an incoming call. In most, but
not all areas, the sum of the RENs should not exceed five (5.0). To be certain of the
number of devices that may be connected to the line, as determined by the total
RENs, contact the telephone company to determine the maximum RENs for the
calling area.

4. If the modem causes harm to the telephone network, the telephone company will

notify you in advance that temporary discontinuance of service may be required.
But if advance notice is not practical, the telephone company will notify the
customer as soon as possible. Also, you will be advised of your right to file a
complaint with the FCC if you believe it is necessary.

5. The telephone company may make changes in its facilities, equipment, operations,

or procedures that could affect the operation of the equipment. If this happens, the
telephone company will provide advance notice in order for you to make the
necessary modifications in order to maintain uninterrupted service.

6. If you experience trouble with this equipment, please contact your sales or service

representative (as appropriate) for repair or warranty information. If the product
needs to be returned to the company service center for repair, contact them directly
for return instructions using one of the following methods:

— Via the Internet: Visit the Paradyne World Wide Web site at

— Outside the U.S.A., call 1-727-530-2340

If the trouble is causing harm to the telephone network, the telephone company
may request that you remove the equipment from the network until the problem is
resolved.

7. The user is not authorized to repair or modify the equipment.

8. This equipment cannot be used on public coin service provided by the telephone

company. Connection to Party Line Service is subject to state tariffs. (Contact the
state public utility commission, public service commission or corporation
commission for information.)
