NTP- D48 Subtend an MS-SPRing from an MS-SPRing
Step 3 Attach fibers from the trunk cards in the subtending node to the MS-SPRing trunk cards on its two
neighboring MS-SPRing nodes. In Figure 5-13, Node 4/Slot 6 connects to Node 7/Slot 13, and
Node 4/Slot 13 connects to Node 5/Slot 6. See the “DLP-D338 Install Fiber-Optic Cables for
MS-SPRing Configurations” task on page 20-37.
Step 4 Create the DCCs on the first STM-N card that will carry the MS-SPRing. See the “DLP-D363 Provision
Regenerator-Section DCC Terminations” task on page 20-68. Alternatively, if additional bandwidth is
needed for CTC management, complete the “DLP-D364 Provision Multiplex-Section DCC
Terminations” task on page 20-71.
Step 5 Repeat Step 4 for the second STM-N trunk card that will carry the MS-SPRing.
Step 6 Complete the “NTP-D40 Provision MS-SPRing Nodes” procedure on page 5-10 for each node that will
be in the MS-SPRing. If you have already provisioned the MS-SPRing, perform this procedure for the
subtending node only.
Step 7 If the subtending MS-SPRing is not already created, complete the “NTP-D41 Create the MS-SPRing”
procedure on page 5-13 to provision the new MS-SPRing. The subtending MS-SPRing must have a ring
name that differs from the ring name of the first MS-SPRing.
Note The subtending node can have one Node ID that is used in both MS-SPRings, or a different
Node ID for each MS-SPRing. For example, the same node can be Node 4 in MS-SPRing 1 and
Node 2 in MS-SPRing 2.
Step 8 From the View menu choose Go to Network View to see the subtending ring.
Figure 5-14 shows an example of two subtending MS-SPRings.

Stop. You have completed this procedure.
