Overview
You can determine operation of the digital network
when it contains 3500 Series DSUs by examining the
DSU's faceplate status indicators and evaluating the
response to diagnostic tests. These tests are used to isolate
problems when they occur, and to verify that problems
have been successfully corrected.
Use the controls and indicators on the standalone and
carrier-mounted DSUs to operate the units and control the
network. The faceplate on both the Model 3510 and
Model 3511 contains 18 light-emitting diodes (LEDs) and
four pushbutton switches.
