Chapter 4 Perform Node Acceptance Tests
NTP-G47 Perform the Line Amplifier Node with OSCM and OSC-CSM Cards Acceptance Test
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
Step 6
Create a loopback on the OSC-CSM card by connecting the LINE TX port to the LINE RX port using a
patchcord and 10-dB bulk attenuator.
Caution
Failure to use proper attenuation might damage equipment.
Step 7
Wait 90 seconds, then in node view click the
Alarms
tab. Verify that the LOS alarm on the OSC-CSM
card has cleared. The clearing of the LOS alarm indicates that the OSC link is active for this side of the
shelf.
Note
An SDCC Termination Failure alarm will continue to appear due to the OSC signal loopback.
If the alarm clears, continue with
. If not, perform the following steps:
a.
Remove the 10-dB bulk attenuator on the OSC-CSM LINE TX and LINE RX ports and reconnect
using only the patchcord.
b.
In node view, click the
Alarms
tab. If the LOS alarm on the OSC-CSM card clears, continue with
. If not, continue with Step
c.
Display the OSC-CSM card in card view.
d.
Click the
Provisioning > Optical Line > Optics Thresholds
tabs.
e.
Under Types, click
Alarm
, then click
Refresh.
f.
Locate the Port 3 Power Failure Low parameter. Double-click the table cell and change the value to
–30 dBm.
g.
Locate the Port 6 Power Failure Low parameter. Double-click the table cell and change the value to
–40 dBm.
h.
Click
Apply
, and then
Yes
.
i.
In node view, click the
Alarms
tab. If the LOS alarm on the OSC-CSM card clears, continue with
. If not, replace the OSC-CSM card.
Step 8
If you are using a tunable laser, follow the manufacturer’s instructions to complete the following steps.
If you are using a TXP_MR_2.5G card, continue with
a.
Set the output power to a nominal value, such as –3 dBm.
b.
Set the tuner to the wavelength under test, then continue with
.
Step 9
If you are using a TXP_MR_2.5G card, complete the
“DLP-G268 Provision TXP_MR_2.5G Cards for
Acceptance Testing” task on page 4-4
for the TXP containing the wavelength you will test. Refer to
, if needed.
Step 10
Measure the TXP output power by connecting the TXP DWDM TX port to a test meter. Record the
results for future reference.
Step 11
Connect the tunable laser transmitter or the TXP_MR_2.5G card DWDM TX port to the OPT-BST
LINE RX port using a 10-dB bulk attenuator.
Caution
Failure to use proper attenuation might damage equipment.
