Quick Start Procedure

The following procedure is for experienced DSU/CSU users who are familiar with the

3166 DSU/CSU installation process and have no special requirements for their

application. See the

ACCULINK 3166 DSU/CSU User’s Guide

for more information.

1. Install the rear connector module loosely onto the 3000 Series Carrier. Do not

tighten the screw.

NOTE:

If an auxiliary backplane for Models 3151 or 3161 DSUs is installed in the

same carrier, verify that it is mounted over slots 9–16. Slot 9 is rendered

inaccessible if the auxiliary backplane is mounted over slots 1–8.

2. Insert the DSU/CSU circuit card into the appropriate slot in the carrier and lock the

latch.

3. Tighten the screw on the rear connector module.

4. Attach a modular cable (not included) to the COM connector of the rear connector

module. (See the

User’s Guide

for detailed cable and connector information.)

Connect the other end to a terminal or PC.

5. Attach the DB25 port cable to the PORT 1 connector on the rear connector module.

Connect the other end of the cable to the customer premises equipment.

6. Attach the network cable to the Network connector on the rear connector module.

Connect the other end of the network cable to the connection provided by the

telephone company.

7. To daisy-chain the diagnostic channel with that of other 3166 DSU/CSUs or a T1

auxiliary backplane, insert one end of the short diagnostic channel extension cable

into either DIAGNOSTIC CHANNEL connector on the rear connector module.

Insert the other end into either DIAGNOSTIC CHANNEL connector of a

neighboring 3166 rear connector module, or the diagnostic channel connector of a

T1 auxiliary backplane.

The power-up self-test begins when power is applied. During the power-up self-test, the

Fail LED flashes, then all LEDs blink twice. When the test is complete, verify that the

DSU/CSU is functional by observing that the OK and NET Sig LEDs are lit.

The Factory 1 configuration for ESF framing format and B8ZS line coding format is the

default configuration and is appropriate for most networks. If this configuration does not

work for you, try the Factory 2 configuration for D4 framing format and AMI line coding

format. To further customize configuration options, refer to

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. 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.

8. Input power to the ac voltage configuration of this product must be provided by a

UL-listed or CSA-certified power source with a Class 2 or Limited Power Source

(LPS) output. Input power to the dc voltage configurations of this product must be

provided by a National Electric Code (NEC) or a Canadian Electric Code (CEC)

Class 2 circuit.

9. This product contains a coin cell lithium battery that is only to be replaced at the

factory. Caution: There is a danger of explosion if the battery is incorrectly

replaced. Replace only with the same type. Dispose of used batteries according to

the battery manufacturer’s instructions. Attention: Il y a danger d’explosion s’il y a

remplacement incorrect de la batterie. Remplacer uniquement avec une batterie du

même type. Mettre au rebut les batteries usagées conformément aux instructions

du fabricant.

10. 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.

EMI Warnings

WARNING:

This equipment has been tested and found to comply with the limits for a

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.
