NTP-A212 Add a BLSR Node
Caution Adding a BLSR node can be service affecting and should be performed during a maintenance window.
Step 1 Draw a diagram of the BLSR where you will add the node. In the diagram, identify the east and west
BLSR OC-N trunk (span) cards that will connect to the new node. This information is essential to
complete this procedure without error. Figure 14-1 shows a drawing of a three-node, two-fiber BLSR
that uses Slots 5 and 12 for the BLSR trunk cards. The dashed arrow shows the new fiber connections
that will be made to add the fourth node to the BLSR.
