NTP- D46 Subtend an SNCP from an MS-SPRing
NTP-D46 Subtend an SNCP from an MS-SPRing
Step 1 In the node that will subtend the SNCP (Node 3 in Figure 5-12), install the two STM-N cards that will
serve as the SNCP trunk (span) cards (Node 3, Slots 6 and 13). See the “NTP-D16 Install STM-N Cards
and Connectors” procedure on page 2-7. If they are already installed, continue with Step 2.
Step 2 Attach fibers from these cards to the SNCP trunk cards on the neighbor SNCP node or nodes. In
Figure 5-12, Node 3/Slot 6 connects to Node 4/Slot 13, and Node 3/Slot 13 connects to Node 4/Slot 6.
See the “DLP-D337 Install Fiber-Optic Cables for SNCP Configurations” task on page 20-33.

Step 3 Complete the “DLP-D60 Log into CTC” task on page 17-49 at the ONS 15454 SDH that will subtend
the SNCP (Node 3 in the example).
Step 4 Complete the “DLP-D363 Provision Regenerator-Section DCC Terminations” task on page 20-68 for
each STM-N card that will carry the SNCP.
Step 5 Log into the SNCP node that connects to the node in Step 3.
Step 6 Complete the “DLP-D363 Provision Regenerator-Section DCC Terminations” task on page 20-68 for
each STM-N card that will carry the SNCP. Alternatively, if additional bandwidth is needed for CTC
management, complete the “DLP-D364 Provision Multiplex-Section DCC Terminations” task on
page 20-71.
Purpose This procedure subtends an SNCP ring from an existing MS-SPRing.
Tools/Equipment One MS-SPRing node must have STM-N cards and fibers to carry the
SNCP.
