Chapter 5 Turn Up Network
d. Verify that the Working Mode field is the one specified by Cisco MetroPlanner, either control power
or control gain. The MetroPlanner parameter is dwdm.rx/tx.amp.WkgModeW/E (rx for OPT-PRE
cards; tx for OPT-BST cards). You can view the parameter on the node view Provisioning >
WDM-ANS tab.
e. Click the Maintenance > ALS tabs and verify that the ALS Mode column displays Auto Restart.
Auto Restart is the default ALS mode.
For each OPT-BST amplifier that is turned up for the first time on your network, repeat Steps
f.
through e.
If OADM nodes have a new circuit running traffic for the first time, check the power values:
Step 11
Note
If the circuit is terminated inside the node, go to node view and click the Provisioning >
•
WDM-ANS > Provisioning tabs. In the Selector area, click West Pin field and then Pin AD Stage.
Verify that the value matches the value for the first OADM card in your circuit heading west to east
shown in the COM RX port, ±2 dB. If the values are outside of the error margins, contact Cisco
qualified personnel to create another MetroPlanner file or refer to the next level of support.
If the circuit passes through the node, go to node view and click the Provisioning > WDM-ANS >
•
Provisioning tabs. Click West Pin field and then Pin AD Stage. Verify that the value matches the
value for the first OADM card in your circuit heading west to east shown in the COM RX port, ±2
dB. Click East Pin and Pout AD Stage. Verify the value matches the value for the first OADM card
in your circuit heading west to east shown in the COM TX port, ±1 dB. If the values are outside of
the error margins, contact Cisco qualified personnel to create another MetroPlanner file or refer to
the next level of support.
If the circuit starts from the node, go to node view and click the Provisioning > WDM-ANS >
•
Provisioning tabs. Click East Pin field and then Pin AD Stage. Verify the value matches the value
for the first OADM card in your circuit heading west to east shown in the COM TX port, ±1 dB. If
the values are outside of the error margins, contact Cisco qualified personnel to create another
MetroPlanner file or refer to the next level of support.
Check the received power range:
Step 12
a. Display the first TXP, MXP, or line card in card view. Complete the
Counts" task on page
Click the Performance > Optics PM tab.
b.
Record the values shown in the RX Optical Pwr field.
c.
d. Click the Provisioning > Optics Thresholds tabs.
e. Compare the value recorded in Step
Low columns. Verify that the received power on the transponder, muxponder, or line card is within
the allowed receiving range according to optical card sensitivity specifications. See the
"Card Reference,"
Step 13 Perform a short-term bit error rate (BER) test:
Complete the
a.
muxponder, or line card.
Click the Payload PM tab, or, if OTN is provisioned, click the OTN PM tab.
b.
c. Perform a short-term BER test using a test set or protocol analyzer.

This step checks the Pin AD Stage (dwdm.[rx/tx].amp.WkgModeW/E) value and the Pout AD
Stage (dwdm.rx.power.InAdE/W) value that characterize every OADM node. The ANS function
uses these values to make the VOA adjustments.
