Quick Start Procedure
Before installing the DSU/CSU, read the Important Safety Instructions beginning on
page 22.
The following procedure is for experienced DSU/CSU users who are familiar with the
3162 DSU/CSU installation process and have no special requirements for their
application. See the ACCULINK 3162 DSU/CSU User’s Guide for more information.
"Procedure
1. Attach the power cord to the rear of the DSU/CSU and the other end to a grounded
115 VAC power outlet.
2. Attach the 3162 DSU/CSU network connection to the T1 network using the
appropriate cable. Attach the 3162 DSU/CSU to the customer premises equipment
via the DTE (DSX-1) and/or port connectors.
3. Power on the DSU/CSU to perform the power-on self-test.
4. During the power-on 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.
5. Connect the COM port to a terminal or PC to configure the DSU/CSU.
6. If you intend to manage the DSU/CSU with SNMP over an Ethernet LAN, connect
the 10BaseT port to your LAN and assign an IP address to the port. See
Configuring the 10BaseT Port on page 4.
7. Configure the ports and channels you intend to use and assign channels to the
network interface. See Configuring DS0 Channels on page 5.
8. 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
Appendix C, Configuration Options,in the User’s Guide.
