Before installing the DSU/CSU, read the
Important Safety Instructions
on page 16. Also,
to ensure compliance with emissions requirements, install ferrite chokes as described in
Quick Start Procedure
on page 2.

Quick Start Procedure
The following procedure is for experienced DSU/CSU users who are familiar with the
317x DSU/CSU installation process and have no special requirements for their
application. See the
ACCULINK 317x E1 Data Service Unit/Channel Service Unit
Operator’s Guide for more information.
Procedure
1. The DSU/CSU is shipped with a power cable appropriate to the country of
installation. Attach the power module cord to the rear of the DSU/CSU and the other
end to a grounded AC power outlet. If you intend instead to use a 24 or –48 VDC
power supply, see the Operator’s Guide.
2. Attach the DSU/CSU network connection to the E1 network using the appropriate
cable. Attach the DSU/CSU to the customer premises equipment via the DTE and
port connectors.
3. Install ferrite chokes on cables attached to Ports 1 and 2 (Model 3172) or Ports 1–4
(Model 3174):
—Pull up on the latch to open
the ferrite choke.
—Place the ferrite choke on the
cable as close to the
DSU/CSU as possible.
—Close the choke around the
cable and press down on the
latch to fasten it.
—Secure the choke with a cable
tie.
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 DSU/CSU.
5. Power on the DSU/CSU to perform the power-up self-test.
6. 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, NETWORK SIG, and DTE SIG LEDs are lit.
7. If you intend to manage the DSU/CSU with SNMP, cable either the COM or AUX
port (as appropriate for your configuration). Then, configure the SNMP
management link.
8. If you do not intend to use the DTE Drop/Insert E1 port, disable it using the
configuration procedures in
Operation and Configuration Options of the Operator’s
Guide. (The default setting for this port is Enabled.)
9. Configure the ports and channels you intend to use and assign channels to the
network interface.

Cabling Examples
The DSU/CSU is supplied with an AC power module. You must provide the DTE and
network cables.
Optional cables that you can order from the company are described in Pin Assignments
in the Operator’s Guide.
NOTE:
The 120Ω/75Ωswitch selects either the 120-ohm balanced network interface or the
75-ohm unbalanced network interface. The RX SHIELD switch selects either an
“open”or “earth”shield connection for the 75-ohm RX interface. (This switch must
be set to “open”when using the 120-ohm interface.)

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 adapter.
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.
9. Input power to the AC voltage configuration of 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.
Input power to the DC voltage configurations of this product must be provided by
one of the following: (1) a National Electric Code (NEC)/Canadian Electric Code
(CEC) Class 2 circuit for use in North America, or (2) a certified Safety Extra Low
Voltage (SELV) circuit input for use in the country of installation.
!

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 terminalsunless 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.
