Overview
This appendix describes the status indicators on the
DSU’s control panel, the Diagnostic Control Panel (DCP)
for a Model 3550 and the Shared Diagnostic Control
Panel (SDCP) for the Model 3551.
Informational messages that may appear on the control
panel while a command is executing, or when a command
is prevented from executing are also described.
Status Indicators
Status indicators provide information on the current
operating condition of the DSU. The status indicators of
the Model 3550 DSU appear on the DCP’s faceplate. The
status indicators for the carrier-mounted Model 3551 DSU
are spread across the the faceplate of the DSU, the SDCP,
and the faceplate of the shared diagnostic unit (SDU), if
installed. Refer to the COMSPHERE 3000 Series Carrier
Installation Manual for SDU status indicator information.
The DSU DCP and SDCP status indicators are described
