Safety Instructions

B3550-A2-GB20-40 July 1999

!Important Safety Instructions

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

included in the manual.

2. This product is intended to be used with a 3-wire grounding type plug – a plug which

has a grounding pin. This is a safety feature. Equipment grounding is vital to ensure

safe operation. Do not defeat the purpose of the grounding type plug by modifying

the plug or using an adaptor.

Prior to installation, use an outlet tester or a voltmeter to check the ac receptacle for

the presence of earth ground. If the receptacle is not properly grounded, the

installation must not continue until a qualified electrician has corrected the problem.

If a 3-wire grounding type power source is not available, consult a qualified

electrician to determine another method of grounding the equipment.

3. 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.

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

persons will walk on the power cord.

5. 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.

6. 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.

7. 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.

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.

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.

Safety Instructions

D3550-A2-GB20-40 July 1999

Government Requirements

The Federal Communications Commission (FCC) requires that instructions pertaining to

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

instructions are listed in this section.

Notice to Users of the Digital Data Service

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

or silk-screened text that contains, among other information, the FCC registration number and

Ringer Equivalence Number (REN) for this equipment. If requested, please 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 of 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 5. 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 ascertain the maximum REN for your calling area.

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.

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 its 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.

The DBM cannot be used on public coin-operated telephone 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.)

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

refer to the Equipment Warranty and Support section of Chapter 1.

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

appropriate network channel interface code for the service you desire.

The DDS Service Order Number is 6.0Y. The jack configurations required are RJ48S for the

Model 3550 DSU and RJ48T for the Model 3551. With an RJ48T configuration, you must specify

the number of data lines you require. Refer to the Technical Specifications section of Chapter 1 for

V.32 DBM jack information.

After the telephone company has installed the requested jack, you can connect the DSU with the

appropriate cable (provided). An FCC-compliant telephone cord and modular plug is 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.
