NTP-A294 Remove a Path Protection Node
Step 20 Click the Circuits tab and verify that no incomplete circuits are present.
Note If the circuits take more than a minute to appear, log out of CTC, then log back in.
Step 21 Complete the “DLP-A198 Clear a Path Protection Force Switch” task on page 18-70 to clear the
protection switch.
Step 22 According to local site practice, complete the “NTP-A177 Path Protection Acceptance Test” procedure
on page 5-22.
Stop. You have completed this procedure.
NTP-A294 Remove a Path Protection Node
Caution The following procedure minimizes traffic outages during node removals.
Caution If you remove a node that is the only BITS timing source for the ring, you also remove the only source
of synchronization for all the nodes in that ring. Circuits that connect to other networks that are
synchronized to a Stratum 1 clock will experience a high level of pointer adjustments, which might
adversely affect customer service.
Step 1 Draw a diagram of the path protection where you will remove the node. In the diagram, identify the
following:
• The node that is connected through its west port to the node that will be removed.
• The node that is connected through its east port to the node that will be removed.
Step 2 Complete the “DLP-A60 Log into CTC” task on page 17-66 at a node in the network where you will
remove a path protection node.
Step 3 Complete the “DLP-A298 Check the Network for Alarms and Conditions” task on page 19-63 to verify
that the path protection is free of alarms. If trouble is indicated (for example, a major alarm exists),
resolve the problem before proceeding. See Chapter 7, “Manage Alarms” or, if necessary, refer to the
Cisco ONS 15454 Troubleshooting Guide.
Step 4 Complete the “DLP-A333 Delete Circuits” task on page 20-21 for circuits that originate or terminate in
the node you will remove. (If a circuit has multiple drops, delete only the drops that terminate on the
node you are deleting.)
Purpose This procedure removes a path protection or multiple path protection
configurations from a node.
