Overview
The 3600 Series DSU supports a variety of status
reports and diagnostic tests for the DSU, DBM, TDM and
MCMP. Status reports are used to obtain more detail about
the current operating condition of the DSU and its options
than the status indicators on the diagnostic control panel
(DCP) provide.
Tests are used to verify proper operation of the DSU
and its options, and to trace the source of a problem to the
network connection, the DTE, or the DSU.
Status reports and diagnostic tests can be performed on
the DSU and its options to provide specific information on
the operating condition.
