the T1 Network Interface Adapter. Connect the other end of the network cable to
the connection provided by the telephone company.

5. Insert the DSU/CSU circuit card into the appropriate slot in the carrier. The
power-up self-test begins.
495-14797
6. If you intend to use front panel emulation, connect the cable from the PC to Port 2
on the Auxiliary Backplane using the COM port adapter and COM-port-to-PC cable.
7. If you do not intend to use the DTE Drop/Insert T1 port, disable it using the
configuration procedures in Chapter 3, Operation, and Appendix C, Configuration
Options, of the ACCULINK 316x Data Service Unit/Channel Service Unit
Operator’s Guide (3160-A2-GB21). (The default setting for this port is Enabled.)
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
Changing Configuration Options in Chapter 3, Operation, and Appendix C,
Configuration Options, in the ACCULINK 316x Data Service Unit/Channel Service
Unit Operator’s Guide.
9. 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.
10. Configure the ports and channels you intend to use and assign channels to the
network interface.
