Test Commands
The test commands enable you to run loopbacks and test patterns on the
DSU/CSU, and to test the front panel LEDs. These tests can help you isolate
areas of trouble if you are having problems with your DSU/CSU.
Use the Test branch of the asynchronous terminal menu tree (see Appendix A) to
access all test commands.
