Stop. You have completed this procedure.
NTP-A299 Convert a Point-to-Point or Linear ADM to a Path
Protection Automatically
Note When upgrading VT tunnels, CTC does not convert the VT tunnel to path protection, but instead creates
a secondary tunnel for the alternate path. The result is two unprotected VT tunnels using alternate paths.
Note If overhead circuits exist on the network, this procedure is service affecting. The overhead circuits will
drop traffic and have a status of PARTIAL after the upgrade is complete.
Step 1 Complete the “DLP-A60 Log into CTC” task on page 17-66 at a node on the point-to-point or linear
ADM. If you are already logged in, continue with Step 2.
Step 2 If the point-to-point or linear ADM is 1+1 protected, complete the “DLP-A155 Delete a Protection
Group” task on page 18-23. If the point-to-point or linear ADM is unprotected, continue with Step 3
Step 3 From either network or node view, click the Circuits tab. Click the circuit you want to upgrade to select
it.
Step 4 From the Tools menu, choose Topology Upgrade > Convert Unprotected to UPSR.
Step 5 To set the path protection parameters, complete the “DLP-A218 Provision Path Protection Selectors”
task on page 19-12.
Step 6 Click Next.
Step 7 Complete one of the following tasks:
a. To route the new path protection circuit manually, complete “DLP-A397 Manually Route a Path
Protection Circuit for a Topology Upgrade” task on page 20-95.
b. To route the new path protection circuit automatically, complete “DLP-A398 Automatically Route
a Path Protection Circuit for a Topology Upgrade” task on page 20-95.
Stop. You have completed this procedure.
Purpose This procedure upgrades a point-to-point or linear ADM to a path
protection without disrupting traffic. You can upgrade STS, VT, and VT
tunnel circuits to path protection. This option is a single circuit
operation.
