Step 14 Complete the
east OPT-BST amplifier.
Disconnect the TXP or tunable laser from the east OPT-BST card.
Step 15
Step 16 Remove the loopback on the west OPT-BST created in
Step 17 Create a loopback on the east OPT-BST by connecting a patchcord from the LINE TX port to the LINE
RX port with a 10-dB bulk attenuator.
If you are using a tunable laser, follow the manufacturer's instructions to complete the following steps.
Step 18
If you are using a TXP_MR_2.5G card, continue with

of the west OPT-BST using a 10-dB bulk attenuator.
Failure to use proper attenuation might damage equipment.
Caution
Step 21 Wait 90 seconds, then in node view click the Alarms tab. Verify that the LOS alarms on the east
OPT-BST and OSCM cards have cleared. The clearing of the LOS alarms indicates that the OSC link is
active on the east side.
Note
If the alarms clear, continue with
Display the east OPT-BST card in card view.
a.
b. Click the Provisioning > Optical Line > Optics Thresholds tabs.
c. Under Types, click Alarms, then click Refresh.
d. Locate the Port 2 Power Failure Low parameter. Double-click the table cell and change the value to
–30 dBm.
e. Locate the Port 4 Power Failure Low parameter. Double-click the table cell and change the value to
–40 dBm.
Click Apply, and then Yes.

An SDCC Termination Failure alarm will continue to appear due to the OSC signal loopback.
An LOS-O alarm appears on the west OPT-BST card, and an LOS alarm appears on the west
OCSM card.
