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.

1. 317x DSU/CSUs are 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 317x DSU/CSU network connection to the E1 network using the
appropriate cable. Attach the 317x DSU/CSU to the customer premises equipment
via the DTE and port connectors.

3. 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.

4. Power on the DSU/CSU to perform the power-up self-test.

5. 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.

6. If you intend to manage the 317x DSU/CSU with SNMP, cable either the COM or
AUX port (as appropriate for your configuration). Then, configure the SNMP
management link.

7. If you do not intend to use the DTE Drop/Insert E1 port, disable it using the
configuration procedures in Chapter 3,

Operation

, and Appendix C,

Configuration

Options

, of the Operator’s Guide. (The default setting for this port is Enabled.)

8. Configure the ports and channels you intend to use and assign channels to the
network interface.

Cabling Examples

The E1 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 Appendix D,

Pin

Assignments

.

NOTE:

The 120Ω/75Ω switch 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.)
