Chapter 6 Turn Up Network
NTP-G54 Provision and Verify a DWDM Network
e. Record the values shown in the RX Optical Pwr field.
f. Click the Provisioning > Optics Thresholds tabs.
g. Verify that the value in Step e falls between the values shown for the RX Power High and
RX Power Low. If so, continue with Step 11. If not, complete one of the following.
–
Power lower than range—Clean the trunk fiber at the patch panel and on the TXP or MXP.
Repeat Steps e through g. If the power is still too low, contact your next level of support.
–
Power higher than range—Add attenuation to the fiber and repeat Steps e through g.
Step 11 Perform a short-term bit error rate (BER) test:
a. Complete the “DLP-G136 Clear Selected PM Counts” task on page 9-7 for the TXP, MXP, or line
card.
b. Display the TXP, MXP, or line card in card view.
c. Click the Performance > Payload PM tabs, or, if OTN is provisioned, the Performance >
OTN PM tabs.
d. Perform a short-term BER test using a test signal from a test set or protocol analyzer.
e. Monitor the payload performance monitoring (PM) for at least 10 minutes for errors.
Note To see an accurate PM count, the BER test results must be consistent with the transmitted bit
rate for at least 10 minutes.
Note For information about using a test set or protocol analyzer, refer to the test set or protocol
analyzer user guide.
Step 12 Repeat Steps 6 through 11 for all sites that have add/drop traffic.
Step 13 If a node fails any test, verify correct setup and configuration and then repeat the test. If the test fails
again, refer to the next level of support.
After all tests are successfully completed and no alarms exist in the network, the network is ready for
service.
Stop. You have completed this procedure.
