NTP-A154 Convert a 1+1 Point-to-Point to a Linear ADM
Manually
Note Optical transmit and receive levels should be in their acceptable range as shown in the specifications
section for each card in Table 2-3 on page 2-15.
Note In a point-to-point configuration, two OC-N cards are connected to two OC-N cards on a second node.
The working OC-N ports have data communications channel (DCC) terminations, and the OC-N cards
are in a 1+1 protection group.
Step 1 Complete the “DLP-A60 Log into CTC” task on page 17-66 at one of the two point-to-point nodes. If
you are already logged in, continue with Step 2.
Step 2 Complete the “DLP-A298 Check the Network for Alarms and Conditions” task on page 19-63.
Step 3 Log into the node that will be added to the point-to-point configuration (the new node).
Note If you are attempting to add an unreachable node you must first log in to the unreachable node
using a separate CTC session and configure that node. Delete any existing protection groups as
described in “DLP-A155 Delete a Protection Group” task on page 18-23. Delete any existing
DCC terminations as described in the “DLP-A156 Delete a Section DCC Termination” task on
page 18-23 or the “DLP-A359 Delete a Line DCC Termination” task on page 20-45.
Step 4 Complete the “NTP-A24 Verify Card Installation” procedure on page 4-2 to ensure that the new node
has two OC-N cards with the same rate as the point-to-point nodes.
Step 5 Complete the “NTP-A35 Verify Node Turn-Up” procedure on page 5-2 for the new node.
Step 6 Physically connect the fibers between the point-to-point node and the new node. The fiber connections
should be connected from working card to working card and protect card to protect card.
Step 7 On the new node, create a 1+1 protection group for the OC-N cards in the point-to-point node that will
connect to the point-to-point node. See the “DLP-A73 Create a 1+1 Protection Group” task on
page 17-81.
Purpose This procedure upgrades a 1+1 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 if you need to back out of the
wizard.
