Configuration
This section describes the configuration of the Multi-Rate DDS
CSU/DSU. This unit is configured using DIP switches shown in
Figure 2-1.
On power up, the unit configures to the hardware settings of
option switches SW1 and SW2. Changes to these settings take
effect after resetting the unit by removing and then reapplying
power. The unit then cycles through its LEDs and reads the new
configuration.
