The power-up self-test begins when power is applied. 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 and NET Sig LEDs are lit.
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 3166 DSU/CSU User’s Guide.
