Chapter 4 Perform Node Acceptance Tests
NTP-G44 Perform the Anti-ASE Hub Node Acceptance Test
Note The OSC terminations created during node turn-up will generate two alarms for each side of the
shelf: one for LOS on the OPT-BST card, and the other an LOS alarm on the OSC_CSM or
OSCM card.
Step 4 In node view, click the Provisioning > WDM-ANS > Port Status tabs. Verify that all statuses under
Link Status are Success - Changed, Success - Unchanged, or Not Applicable. If any are not, complete
the following steps:
a. Delete the two OSC channels using the “DLP-G186 Delete an OSC Termination” task on
page 10-41.
b. Complete the “NTP-G37 Run Automatic Node Setup” procedure on page 3-83.
c. Create the OSC channels using the “NTP-G38 Provision OSC Terminations” procedure on
page 3-84.
Step 5 From your Cisco MetroPlanner site configuration file, identify the dropped and added channels that are
configured in pass-through mode in both directions.
Note Configuring a channel pass-through mode means that the channel is dropped along one direction
by a 32DMX-O (15xx.xx TX port) located on one side (west or east) of the shelf, and then added
by a 32MUX-O (1522.22 RX port) on the opposite side of the shelf but in the same direction.
The channel is not terminated inside the site.
Step 6 Create a loopback on the west OPT-BST amplifier by connecting a patchcord from the LINE TX port to
the LINE RX port with a 10-dB bulk attenuator.
Step 7 Verify that the OSC link becomes active on the west OSCM or OSC-CSM card. (The OSC Termination
must already be provisioned. If not, complete the “NTP-G38 Provision OSC Terminations” procedure
on page 3-84.)
Step 8 For pass-through channels, continue with Step 9. For add and drop channels, continue with Step 18.
Step 9 Verify the first channel connection configured in pass-through mode in both directions:
a. If you are using a tunable laser, set the output power to a nominal value, such as –3 dBm. If you are
using a TXP_MR_2.5G card, continue with Step b.
b. Set the tunable laser or TXP_MR_2.5G card to a corresponding wavelength on the 100-GHz ITU-T
grid. Refer to the tunable laser manufacturer’s documentation or the “DLP-G268 Provision
TXP_MR_2.5G Cards for Acceptance Testing” task on page 4-4.
c. Connect the tunable laser transmitter or the TXP_MR_2.5G card DWDM TX port to the LINE RX
port of the east OPT-BST using a 10-dB bulk attenuator.
Step 10 Complete the “DLP-G80 Verify the OPT-PRE Amplifier Laser and Power” task on page 4-41 for the
east OPT-PRE amplifier.
Step 11 Complete the “DLP-G269 Verify the 32DMX-O Power” task on page 4-42 for the west 32MUX-O and
32DMX-O cards.
Step 12 Complete the “DLP-G79 Verify the OPT-BST Amplifier Laser and Power” task on page 4-40 for the
west OPT-BST amplifier.
Step 13 Complete the “DLP-G80 Verify the OPT-PRE Amplifier Laser and Power” task on page 4-41 for the
west OPT-PRE amplifier.
Step 14 Complete the “DLP-G269 Verify the 32DMX-O Power” task on page 4-42 for the west 32MUX-O and
32DMX-O cards.
