extinguish for 10 seconds. Then the proper LEDs will light to indicate the shelf’s
current status.
Local Equipment and Cross-Connect
Test
Description
This test verifies proper operation of the circuit packs and the circuit pack
positions, which are equipped in the DDM-2000 OC-3 shelf. It verifies proper
cabling from the DDM-2000 OC-3 to the DSX cross-connect panel or connecting
equipment. The shelf must successfully pass this test before testing any other
feature of the DDM-2000 OC-3.
On initial installation/turn-up of Releases 9 and 11 systems there are no default
cross-connects; thus all cross-connects need to be entered for the tests. In
Releases 9 and 11 VT and STS-1 cross-connects are allowed and can be entered
as a group, rather than individually.
Upon completion of this test all cross-connections will be deleted and later
reentered to fit individual ring applications.
To understand cross-connects and the ring philosophy, refer to the ‘Description
Section’ under ‘Establishing Cross-Connects and System Test’ of this section.
NOTE
:
If the shelf is not fully equipped, move circuit packs around and repeat the
test. Test all circuit pack positions which have DSX cabling.
NOTE
:
After completing this test, isolate and correct any incorrect wiring or isolate
and replace any failed units. If any cabling is corrected or units replaced,
repeat the Local Equipment and Cross-Connect tests until the tests pass
without failures.
NOTE
:
Refer to 363-206-280,
DDM-2000 OC-3 Multiplexer User/Service Manual
,
Issue 1 for complete command descriptions.
NOTE
:
Unterminated optical connectors may emit laser radiation. Do not view
beam with optical instruments.
