Step 2 Complete the “DLP-D298 Check the Network for Alarms and Conditions” task on page 19-83.
Step 3 Complete the “DLP-D189 Verify that a 1+1 Working Slot is Active” task on page 18-77 for each node.
Step 4 Complete the “DLP-D155 Delete a Protection Group” task on page 18-47 for each 1+1 protection group
that supports the point-to-point or linear ADM span.
Step 5 Complete the “DLP-D363 Provision Regenerator-Section DCC Terminations” task on page 20-68 at the
protect cards in all nodes that will be part of the SNCP ring. Alternatively, if additional bandwidth is
needed for CTC management, complete the “DLP-D364 Provision Multiplex-Section DCC
Terminations” task on page 20-71.
Step 6 Complete the “DLP-D27 Delete Circuits” task on page 17-21 and the “NTP-D323 Create an
Automatically Routed High-Order Circuit” procedure on page 6-55 to delete and recreate the circuits
one at a time.
Note If you want to add additional nodes to the SNCP, see the “NTP-D105 Add an SNCP Node” procedure
on page 14-10.
Note An SNCP is the default configuration if the cards installed are installed and the DCCs are configured.
Stop. You have completed this procedure.
NTP-D320 Convert an SNCP to a Two-Fiber MS-SPRing
