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 the procedure
below. 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
Network connections are provided through the
3000 Series Carrier. Refer to
Figure 3-2
as you read the
following sections and set up your network connections.
Connecting to the NMS
A Model 3616 DualFlow DSU is set up for network
diagnostic connection through the shared diagnostic unit
(SDU), which is installed in Slot 0 of the carrier. Refer to
the COMSPHERE 3000 Series Carrier, Installation
Manual to set up the network diagnostic connection.
For connection of the DSU, see
Appendix E
of this
guide. For pin assignments, see
Appendix D
.
Connecting to the Dial (or PSTN) or
Switched 56 kbps Network
Connection to the dial network (or public switched
telephone network – PSTN) or Switched 56 kbps network
for the carrier-mounted Model 3616 DSU is through a
network interface module (NIM) that is installed onto the
carrier’s backplane (see
Figure 3-2
). Refer to the
COMSPHERE 3000 Series Carrier, Installation Manual
for additional information or to install the NIM.
