Quick Start Procedure
Before installing the CSU, see the Important Safety Instructions beginning on
pageNO TAG.
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.

2
NOTE:
To configure the CSU remotely, refer to the Acquiring/Releasing the User
Interface
section in Chapter 5, Security, in the Operator’s Guide .
5. If you intend to manage the 3150 CSU with SNMP over an Ethernet LAN, connect
the 10BaseT port to your LAN and assign an IP address to the port.
6. Verify that configuration options are appropriate for your network.
7. During the power-on self-test, the FAIL LED flashes, then all LEDs blink twice.
When the test is complete, verify that the CSU is functional by observing that the
OK, NETWORK SIG, and DTE SIG LEDs are lit.

!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

Government Requirements and Equipment Return
Certain governments require that instructions pertaining to CSU 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
1. This equipment complies with Part 68 of the FCC rules. On the equipment is a label
that contains, among other information, the FCC registration number and ringer
equivalence number (REN) for this equipment. The label is located on the bottom
of the 3150 CSU. If requested, this information must be provided to the telephone
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.
