NTP- D154 Convert a Point-to-Point to a Linear ADM Manually
Step 11 When the fibers are connected properly, click Next. The Update Circuit(s) on Node-Name page appears.
Note The Back button is not enabled in the wizard. You can click the Cancel button at this point and
choose the Yes button if you want to cancel the upgrade protection procedure. If the procedure
fails after you have physically moved the fiber-optic cables, you will need to restore the
fiber-optic cables to the original positions and verify (through CTC) that traffic is on the working
path of the nodes before restarting the process. To check traffic status go to node view, click the
Maintenance > Protection tabs. In the Protection Groups area, click the 1+1 protection group.
You can see the status of the traffic in the Selected Group area.
Step 12 Click Next on the Update Circuit(s) on Node-Name page to continue with the procedure.
Step 13 The Force Traffic to Protect Path page states that it is about to force the traffic from the working to
protect path for the terminal nodes. When you are ready to proceed, click Next.
Step 14 Follow each step as instructed by the wizard as it guides you through the process of refibering the
working path between nodes and forcing the traffic back to the working path.
Step 15 The Force Traffic to Working Path page states that it is about to force the traffic from the protect to
working path for the terminal nodes. When you are ready to proceed, click Next.
Step 16 The Completed page appears. This page is the final one in the process. Click Finish.
Step 17 Stop. You have completed this procedure.
NTP-D154 Convert a Point-to-Point to a Linear ADM Manually
Note Optical transmit and receive levels should be in their acceptable range as shown in Table 2-4 on
page 2-17.
Note In a point-to-point configuration, two STM-N cards are connected to two STM-N cards on a second
node. The working STM-N ports have data communications channel (DCC) terminations, and the
STM-N cards are in a 1+1 protection group.
Purpose This procedure upgrades a point-to-point configuration (two nodes) to a
linear ADM configuration (three or more nodes) manually, that is,
without using the in-service topology upgrade wizard. Use this
procedure if the wizard is unavailable or you need to back out of the
wizard.
