Installing the Model 3615 DualFlow DSU
2-5 3615-A2-GB20-40 July 1999
Power-Up Routine
When power is applied, the DSU:
•
Runs a Device Test on itself and the DBM.
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.
If the DSU or DBM fails this test, follow these steps.
Refer to Appendix A as you perform the procedures
described in this guide. Refer to
Chapters 4 and 5 for
additional examples and procedures.

Connecting to the Network
The DSU provides three interfaces (often called jacks).
One jack connects the DSU to the 6700 or 6800 Series
NMS, one connects the DSU to the dial (or public
switched telephone network – PSTN) network, and one
connects the DSU to the DDS network. Follow the
appropriate procedure when making your network
connections.
