M
odem Requirements
This equipment operates in compliance with Part 68 of
the FCC rules. In accordance with this regulation, the fol-
lowing requirements should be observed.
Type of Service
Your Dell portable computer modem is designed to be
used on standard device telephone lines. The modem
connects to the telephone line by means of a standard
jack called the USOC RJ-11C. Connection to a
telephone-company-provided coin service (central-
office-implemented systems) is prohibited. Connection
to party-line service is subject to state tariffs.
Telephone Company Procedures
The goal of the telephone company is to provide you with
the best service it can. To this end, the company may
need to occasionally make changes in its equipment,
operations, or procedures. If these changes might affect
your service or the operation of your equipment, the tele-
phone company will give you notice, in writing, to allow
you to make any changes necessary to maintain uninter-
rupted service.
If you have any questions about your telephone line, such
as how many pieces of equipment you can connect to it,
the telephone company will provide this information on
request.
In certain circumstances, it may be necessary for the tele-
phone company to request information from you
concerning the equipment that you have connected to
your telephone line. On request of the telephone com-
pany, provide the FCC registration number and the ringer
equivalence number (REN) of the equipment that is con-
nected to your line; both of these items are listed on the
equipment label. The sum of all the RENs on your tele-
phone line should be less than five to ensure proper
service from the telephone company. In some cases, a
sum of five may not be usable on a given line.
If Problems Arise
If your telephone equipment is not operating properly,
immediately disconnect the modem from the telephone
line, as it may harm the telephone network. If the tele-
phone company notes a problem, it may temporarily
discontinue service. When practical, it will notify you in
advance of this disconnection. If advance notice is not
feasible, you will be notified as soon as possible. When
you are notified, you will be given the opportunity to cor-
rect the problem and informed of your right to file a
complaint with the FCC.
If repairs are needed on your Dell portable computer
modem, they should be performed by Dell Computer
Corporation or an authorized representative of Dell Com-
puter Corporation. To return products, you must call Dell
customer service at the toll-free number shown in Chap-
ter 5, “Getting Help,” to receive a Credit Return
Authorization Number. For more information on return-
ing equipment, see the “Total Satisfaction” Return Policy
in Appendix D, “Warranties and Return Policy.”
Installation and Labeling
Your Dell portable computer modem provides all the
connections necessary for proper operation. Connection
to the telephone network should be made with standard
modular cords that connect to the jacks or the modem.
Load Number
The load number (LN) assigned to each terminal device
denotes the percentage of the total load to be connected
to a telephone loop which is used by the device to prevent
overloading. The termination on a loop may consist of
any combination of devices subject only to the require-
ment that the total of the LNs of all the devices does not
exceed 100. An alphabetic suffix is also specified in the
LN for the appropriate ringing type (A or B), if applica-
ble. For example, LN = 20 A designates an LN of 20 and
an “A” type ringer.
