Model 3610 Dsu Electrical Connection - Paradyne COMSPHERE 3610 Operator's Manual

Power-Up Routine
When power is applied, the DSU:
Determines what options (DBM, MUX-TDM or
MCMP) are installed, if any.
Runs a Device Test on itself and each of the
installed options.
During the tests, all indicators on the DCP light
briefly and the message Power-Up Tests appears
on the liquid crystal display (LCD).
Displays the results of each test momentarily as
Pass, Fail, or Abrt. (Abrt indicates that the Device
Test was aborted because a network loopback was
in progress during the power-up procedure.) These
tests take about 20 seconds to complete.
