Step 12 Complete the “DLP-D363 Provision Regenerator-Section DCC Terminations” task on page 20-68 at the
end nodes; provision the slot in each node that is not already in the RS-DCC Terminations list (in the
Figure 13-3 example, Port 1 of Node 1/Slot 5 and Port 1 of Node 3/Slot 13). (Alternatively, if additional
bandwidth is needed for CTC management, complete the “DLP-D364 Provision Multiplex-Section DCC
Terminations” task on page 20-71.)
Step 13 For circuits provisioned on a VC4 that is now part of the protection bandwidth (VC4s 3 to 4 for an
STM-4 MS-SPRing, VC4s 9 to 16 for an STM-16 MS-SPRing, and VC4s 33 to 64 for an STM-64),
delete and recreate each circuit:
a. Complete the “DLP-D27 Delete Circuits” task on page 17-21 for one circuit.
b. Create the circuit on VC4s 1 to 2 for an STM-4 MS-SPRing, 1 to 8 for an STM-16 MS-SPRing, or
1 to 32 for an STM-64 MS-SPRing on the fiber that served as the protect fiber in the linear ADM.
See the “NTP-D324 Create a Manually Routed High-Order Circuit” procedure on page 6-60 for
instructions.
c. Repeat Steps a and b for each circuit residing on an MS-SPRing protect VC4.
Step 14 Complete the “NTP-D41 Create the MS-SPRing” procedure on page 5-13 to put the nodes into an
MS-SPRing.
Stop. You have completed this procedure.
NTP-D351 Convert a Point-to-Point or Linear ADM to an SNCP
Automatically
Note When upgrading VT tunnels, CTC does not convert the VT tunnel to SNCP, 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, an in-service topology upgrade 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-D60 Log into CTC” task on page 17-49 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-D155 Delete a Protection
Group” task on page 18-47. If the point-to-point or linear ADM is unprotected, continue with Step 3.
Purpose This procedure upgrades a point-to-point or linear ADM to an SNCP
without disrupting traffic. You can upgrade synchronous transport signal
(STS), Virtual Tributary (VT), and VT tunnel circuits to SNCP. This
option is a single circuit operation.
