Operational Tests
NOTE
:
Most of the operational tests can be performed with or without a terminal.
However, performing these tests with a terminal is preferred because it pro-
vides more diagnostic information.
NOTE
:
For a list of LED descriptions, DDM-2000 OC-3 commands, and more infor-
mation on the use of a terminal, refer to the "Installation Test" section of this
manual.
!
CAUTION:
The operational tests in this section are run only in an out-of-service mode of
operation. Office alarms will be connected only during the office alarm test to
prevent constant alarms throughout this section.
Office Alarm Test
Description
This test verifies proper operation/wiring of the office alarms in a new equipment
building system (NEBS) (central office) environment.
NOTE
:
This test should be performed on all shelves.
NOTE
:
The office alarms should be connected at this time if they are not already
connected. Table 9-3 lists the office alarms connections.
NOTE
:
After completing the office alarm test, the DDM-2000 OC-3 office alarms
should be disconnected from the office alarm system. This will prevent the
office alarms from being activated while performing the other tests in this
section.
NOTE
:
It is a requirement that alarms on the DDM-2000 OC-3 do not affect and
are not affected by other equipment via office alarm connections. During
this test, the alarm state of other equipment connected to the same office
alarms as the DDM-2000 OC-3 should be examined after creating or clear-
ing every alarm.
