Local equipment and cross-connect tests

Description

The tests in this section verify the proper operation of the circuit packs and the circuit pack

positions in the Alcatel-Lucent 1665 DMX shelf. It verifies proper cabling from the

Alcatel-Lucent 1665 DMX to the DSX cross-connect panel or connecting equipment. The

shelf must successfully pass this test before testing any other feature of the Alcatel-Lucent

1665 DMX.

It is assumed that

completed and the Alcatel-Lucent 1665 DMX shelf has fiber loop-back cables on the

Main OLIUs with proper LBOs installed, and synchronization set to free-running.

On initial installation/turn-up of Alcatel-Lucent 1665 DMX there are no default cross-

connects. All cross-connects need to be entered for these tests. Upon completion of this

test all cross-connections will be deleted.

Note:

slots and repeat the test. Test all circuit pack positions which have DSX cabling.

Note:

and replace any failed units. If any cabling is corrected or units replaced, repeat the

Local Equipment and cross-connect tests until the units pass without failure.

A properly grounded ESD wrist strap MUST be worn when handling circuit packs.

Unterminated optical connectors may emit laser radiation. Do not view beam with

optical instruments.

DS1 terminating equipment loopback testing

Facility Loopback testing allows the installer to verify electrical cabling to the DS1

Terminating Equipment. This test is only required if the Alcatel-Lucent 1665 DMX shelf

is connected to DS1 terminating equipment such as a DACS. It will be necessary to work

with the Customer Network Control Center to have them establish a terminal loopback. If

the shelf is NOT connected to DS1 terminating equipment, skip this section and continue

with

DS1 non-terminating equipment transmission testing (optical main OLIU) (p.

If the shelf is not fully equipped, move circuit packs to unequipped function

After completing this test, isolate and correct any incorrect wiring or isolate
