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

3150 CSU installation process and have no special requirements for their application.
Refer to the

ACCULINK CSU Operator’s Guide

for more information.

1. Attach the power cord to the rear of the CSU and the other end to a grounded
115 Vac power outlet.

2. Attach the DTE cable (DB15) and the 8-pin network cable to the DTE and
NETWORK connectors, respectively, located on the CSU rear panel. Then,
connect the other end of the DTE cable to the CPE. Connect the other end of the
network cable to the RJ48C jack provided by the telephone company. See
Appendix E,

Pin Assignments

, in the

Operator’s Guide

for more information.

3. Power on the CSU to perform the power-on self-test. See

Power-On Self-Test

in

Chapter 2,

Installation

, of the

Operator’s Guide

for more information.

4. If you intend to use front panel emulation, connect the cable from the PC to the
COM port on the rear panel of the CSU.

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 three-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 three-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.

9. The Model 3150’s input power to the AC voltage configuration of this product must
be provided by a UL Listed or CSA Certified, Class 2 transformer. 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), Part 1, Class 2 circuit.

10. 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.

company.

2. There are two types of telephone lines associated with the standalone equipment.
The T1 network connection should be made using a Universal Service Order Code
(USOC) type RJ48C jack. The Service Order Code 6.0F should be specified to the
telephone company when ordering the T1 line. In addition, the proper Facility
Interface Code must be specified to the Telephone Company. The CSU can be
configured to support any of the following framing format and line signaling
techniques. The CSU’s configuration must correspond to the T1 line’s parameters.
The 3150 CSU’s internal modem connects to the Public Switched Telephone
Network using a USOC Type RJ11C jack. The Facility Interface Code 02LS2 along
with the RJ11C jack should be specified to the telephone company when ordering
a dial line for the modem.

3150 CSU Facility Interface Codes

Code

Description

04DU9-BN 1.544 Mbps superframe format (SF) without line power
04DU9-DN 1.544 Mbps SF and B8ZS without line power
04DU9-1KN 1.544 Mbps ANSI ESF without line power
04DU-1SN 1.544 Mbps ANSI ESF and B8ZS without line power

3. The ringer equivalence number (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 DSU/CSU 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.

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
