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

tests take about 20 seconds to complete.

Procedure
1. Confirm the hardware options that are installed, if
any.
2. Go to the Configuration (Confg) branch, load and
save a factory-set configuration (FacC or FacT).
3. Return to the Test branch.
4. Re-execute the Device Test. If the test passes,
continue with this procedure.
If the test fails again, contact your service
representative for information on how to return the DSU.
Since the DSU is not connected to the network, the red
Alrm indicator is lit and the LCD displays No Signal to
indicate a facility alarm. The LCD displays Health and
Status information as described in the
Status Branch
section of Chapter 4.
