NOTES:

Your terminal or PC software must be set to communicate at a rate of

9.6 kbps, using characters of 8 bits, one stop bit, and no parity.

If you connect an external modem instead of an asynchronous terminal or

PC:

— Use an EIA-232 crossover cable as described in Appendix C,

Cables and

Pin Assignments,

in the User’s Guide.

— If possible, configure your modem to use standard RS232 detection and

control for CTS, DSR, DTR, LSD, and RTS.

— If possible, disable AT commands on your modem.

Important Safety Instructions

1. Read and follow all warning notices and instructions marked on the product

or included in the manual.

2. Slots and openings in the cabinet are provided for ventilation. To ensure

reliable operation of the product and to protect it from overheating, these

slots and openings must not be blocked or covered.

3. Do not allow anything to rest on the power cord and do not locate the product

where persons will walk on the power cord.

4. Do not attempt to service this product yourself, as opening or removing

covers may expose you to dangerous high voltage points or other risks. Refer

all servicing to qualified service personnel.

5. General purpose cables are provided with this product. Special cables, which

may be required by the regulatory inspection authority for the installation site,

are the responsibility of the customer.

6. When installed in the final configuration, the product must comply with the

applicable Safety Standards and regulatory requirements of the country in

which it is installed. If necessary, consult with the appropriate regulatory

agencies and inspection authorities to ensure compliance.

7. Input power to this product must be provided by one of the following: (1) a UL

Listed/CSA certified power source with a Class 2 or Limited Power Source

(LPS) output for use in North America, or (2) a certified power source with a

Safety Extra Low Voltage (SELV) output for use in the country of installation.

8. A rare phenomenon can create a voltage potential between the earth

grounds of two or more buildings. If products installed in separate buildings

are interconnected, the voltage potential may cause a hazardous condition.

Consult a qualified electrical consultant to determine whether or not this

phenomenon exists and, if necessary, implement corrective action prior to

interconnecting the products.

9. In addition, if the equipment is to be used with telecommunications circuits,

take the following precautions:

— Never install telephone wiring during a lightning storm.

— Never install telephone jacks in wet locations unless the jack is

specifically designed for wet locations.

— Never touch uninsulated telephone wires or terminals unless the

telephone line has been disconnected at the network interface.

— Use caution when installing or modifying telephone lines.

— Avoid using a telephone (other than a cordless type) during an electrical

storm. There may be a remote risk of electric shock from lightning.

— Do not use the telephone to report a gas leak in the vicinity of the leak.

Government Requirements

Certain governments require that instructions pertaining to connection to the

telephone network be included in the installation and operation manual. Specific

instructions are listed in the following sections.

Notice to Users of the United States Telephone Network

This equipment complies with Part 68 of the FCC rules. On the bottom of the

equipment is a label that contains, among other information, the FCC registration

number for this equipment. If requested, please provide this information to your

telephone company.

If your DSU causes harm to the telephone network, the telephone company may

discontinue your service temporarily. If possible, they will notify you in advance.

But if advance notice is not practical, you will be notified as soon as possible. You

will be advised of your right to file a complaint with the FCC.

Your telephone company may make changes in facilities, equipment, operations,

or procedures that could affect the proper operation of your equipment. If so, you

will be given advance notice so as to give you an opportunity to maintain

uninterrupted service.

No repairs may be performed by the user. Should you experience difficulty with

this equipment, refer to

Warranty, Sales, and Service Information

on page 10.

7510-A2-GN10-30 January 1999

For Digital Data Service (DDS) installations, inform the local telephone company

of the appropriate facility interface code for the service you desire.

DDS Facility

Interface Code Data Rate

04DU5-56 56 Kbps

04DU5-64 64 Kbps

The DDS Service Order Number is 6.0Y. The jack configuration required is

RJ48S. Refer to Appendix D,

Technical Specifications

, in the User’s Guide.

After the telephone company has installed the requested service and jack, you

can connect the DSU with the cable provided. An FCC-compliant telephone cord

and modular plug are provided with this equipment. This equipment is designed

to be connected to the telephone network or premises wiring using a compatible

modular jack that is Part 68 compliant.

Notice to Users of the Canadian Telephone Network

The Industry Canada label identifies certified equipment. This certification means

that the equipment meets telecommunications network protective, operational

and safety requirements as prescribed in the appropriate Terminal Equipment

Technical Requirements document(s). The Department does not guarantee the

equipment will operate to the user’s satisfaction.

Before installing this equipment, users should ensure that it is permissible to be

connected to the facilities of the local telecommunications company. The

equipment must also be installed using an acceptable method of connection. The

customer should be aware that compliance with the above conditions may not

prevent degradation of service in some situations.

Repairs to certified equipment should be coordinated by a representative

designated by the supplier. Any repairs or alterations made by the user to this

equipment, or equipment malfunctions, may give the telecommunications

company cause to request to disconnect the equipment.

Users should ensure for their own protection that the electrical ground

connections of the power utility, telephone lines and internal metallic water pipe

system, if present, are connected together. This precaution may be particularly

important in rural areas.

CAUTION:

Users should not attempt to make such connections themselves, but

should contact the appropriate electric inspection authority, or

electrician, as appropriate.

The Ringer Equivalence Number (REN) assigned to each terminal device

provides an indication of the maximum number of terminals allowed to be

connected to a telephone interface. The termination on an interface may consist

of any combination of devices subject only to the requirement that the sum of the

Ringer Equivalence Numbers of all the devices does not exceed 5.

If your equipment is in need of repair, refer to the procedures described in the

next section.
