Release 13 (TARP) Installation Tests
LED Test
Description
This test verifies proper operation of all the LEDs on the DDM-2000 OC-3 shelf.
Operation of all the LEDs is necessary to assist in trouble isolation.
If there are any LED failures, determine if the problem is with the circuit pack or
shelf and replace the faulty unit.
If the shelf is not fully equipped, move circuit packs around and repeat the test in
all circuit pack positions.
Procedure
Issue the command
test-led;
.
The DDM-2000 OC-3 will respond with
In Progress . . . .
for the duration of the test and will issue a prompt CMPLD when the test has
completed. All LEDs on the shelf under test should light for 10 seconds, then
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 Release 13 systems there are no default cross-
connects; thus all cross-connects need to be entered for the tests. In Release 13
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.
