Step 2 On the shelf graphic, double-click the card with the port(s) you want to put in or out of service. The card view appears.
Step 3 Click the Provisioning > Line tabs.
Step 4 Under State, choose one of the following:
•IS—The port is in-service.
•OOS—The port is out-of-service. Traffic is not passed on the port until the service state is changed to IS, OOS_MT, or OOS_AINS.
•OOS_MT—The port is in a maintenance state. The maintenance state does not interrupt traffic flow, alarm reporting is suppressed, but traffic is carried and loopbacks are allowed. Raised fault conditions, whether their alarms are reported or not, can be retrieved on the CTC Conditions tab or by using the TL1 RTRV-COND command. Use OOS_MT for testing or to suppress alarms temporarily. Change the state to IS, OOS, or OOS_AINS when testing is complete.
•OOS_AINS—The port is in an auto-inservice state; alarm reporting is suppressed, but traffic is carried and loopbacks are allowed. Raised fault conditions, whether their alarms are reported or not, can be retrieved on the CTC Conditions tab or by using the TL1 RTRV-COND command.
Step 5 If you set State to OOS-AINS, set the soak period time in the AINS Soak field. This is the amount of time that the state will stay in OOS-AINS state after the signal is continuously received.

Step 1 Complete the "DLP-D338 Install Fiber-Optic Cables for MS-SPRing Configurations" task on page 2-30, verifying that the following rules are observed:
•Verify that the east port at one node is connected to the west port on an adjacent node, and this east to west port connection is used at all MS-SPRing nodes, similar to Figure 5-2. In the figure, the STM-N drop card on the left side of the shelf is the west port, and the drop card on the right side of the shelf is considered the east port.
•For four-fiber MS-SPRings, verify that the same east port to west port connection is used for the working and protect fibers, similar to Figure 5-3. Verify that the working and protect card connections are not mixed. The working cards are the cards where you will provision the DCC terminations.

Figure 5-3 Four-Node, Four-Fiber MS-SPRing Fiber Connection Example
Step 2 Log into an ONS 15454 SDH that you want to configure in an MS-SPRing. See the "DLP-D60 Log into CTC" task on page 3-23 for instructions. If you are already logged in, continue with Step 3.
Step 3 Complete the "DLP-D253 Provision SDH DCC Terminations" task. Provision the two ports/cards that will serve as the MS-SPRing ports at the node. For four-fiber MS-SPRings, provision the DCC terminations on the STM-N cards that will carry the working traffic, but do not provision DCCs on the protect cards.
Note If an ONS 15454 SDH is not connected to a corporate LAN, DCC provisioning must be performed through a direct (craft) connection to the node. Remote provisioning is possible only after all nodes in the network have DCC provisioned to in-service STM-N ports.
Step 4 For four-fiber MS-SPRings, complete the "DLP-D214 Change the Service State for a Port" task to put the protect STM-N cards/ports in service.
Step 5 If an MS-SPRing span passes through third-party equipment that cannot transparently transport the K3 byte, complete the "DLP-D89 Remap the K3 Byte" task. This task is not necessary for most users.
Step 6 Repeat Steps 2 through 4 at each node that will be in the MS-SPRing. Verify that the EOC (DCC Termination Failure) and LOS (Loss of Signal) are cleared after DCCs are provisioned on all nodes in the ring.
Step 7 Complete the "126 Create an MS-SPRing" procedure.
Stop. You have completed this procedure.

Step 1 In the node that will subtend the SNCP (Node 3 in Figure 5-9), install the two (east/west) STM-N cards that will serve as the SNCP trunk (span) cards (Node 3, Slots 6 and 13). See the "NTP-D16 Install the Optical Cards" procedure on page 2-12. If they are already installed, go to Step 2.
Step 2 Attach fibers from these cards to the SNCP trunk cards on the neighbor SNCP node or nodes. In Figure 5-9, Slot 6/Node 3 connects to Slot 13/Node 4, and Slot 13/Node 3 connects to Slot 6/Node 4.
Step 3 Log into the ONS 15454 SDH that will subtend the SNCP. See the "DLP-D60 Log into CTC" task on page 3-23 for instructions.
Step 4 Complete the "DLP-D253 Provision SDH DCC Terminations" task 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-D253 Provision SDH DCC Terminations" task for each STM-N card that will carry the SNCP.
Step 7 Repeat Step 6 for each node in the SNCP.
Step 8 From the View menu, choose Go To Network View.

Step 1 In the SNCP node that will subtend the MS-SPRing, install the two (east and west) STM-N cards that will serve as the MS-SPRing trunk (span) cards (in Figure 5-9, Node 3, Slots 5 and 12). See the "NTP-D16 Install the Optical Cards" procedure on page 2-12.
Step 2 Attach fibers from the cards in Step 1 to the MS-SPRing trunk cards on another MS-SPRing node or nodes. In Figure 5-9, Slot 5/Node 3 connects to Slot 12/Node 2, and Slot 12/Node 3 connects to Slot 5/Node 1.
Step 3 Log into the ONS 15454 SDH that will subtend the MS-SPRing (the node in Step 1). See the "DLP-D60 Log into CTC" task on page 3-23 for instructions. If you are already logged in, continue with Step 4.
Step 4 Create the DCCs on both STM-N trunk cards (east and west) that will carry the MS-SPRing. See the "DLP-D253 Provision SDH DCC Terminations" task for instructions.
Step 5 Create the subtending MS-SPRing:
a. Complete the "40 Provision MS-SPRing Nodes" procedure 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.
b. Complete the "126 Create an MS-SPRing" procedure. Include the node in Step 3 (the node that will subtend the MS-SPRing) in the MS-SPRing.
Step 6 From the View menu, choose Go to the Network View to see the subtending ring.
Stop. You have completed this procedure.

Note This procedure assumes that all nodes are configured for the MS-SPRing. If you need to add a node to an MS-SPRing, see the "NTP-D12 Add an MS-SPRing Node" procedure on page 14-2.
Step 1 Log into the node that will subtend the MS-SPRing. See the "DLP-D60 Log into CTC" task on page 3-23 for instructions. If you are already logged in, continue with Step 2.
Step 2 Install the STM-N cards that will serve as the MS-SPRing trunk (span) cards if they are not already installed. See the "NTP-D16 Install the Optical Cards" procedure on page 2-12.
Figure 5-10 shows two MS-SPRings shared by one ONS 15454 SDH. Ring 1 runs on Nodes 1, 2, 3, and 4. Ring 2 runs on Nodes 4, 5, 6, and 7 and represents the subtending ring added by this procedure. Two MS-SPRings, Ring 1 and Ring 2, are provisioned on Node 4. Ring 1 uses cards in Slots 5 and 12, and Ring 2 uses cards in Slots 6 and 13.

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 5-10, Node 4/Slot 6 connects to Node 7/Slot 13, and Node 4/Slot 13 connects to Node 5/Slot 6.
Step 4 Create the DCCs on the first STM-N card that will carry the MS-SPRing. See the "DLP-D253 Provision SDH DCC Terminations" task for instructions.
Step 5 Repeat Step 4 for the second STM-N trunk card that will carry the MS-SPRing.
Step 6 Complete the "40 Provision MS-SPRing Nodes" procedure 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 "126 Create an MS-SPRing" procedure to provision the new MS-SPRing. The subtending MS-SPRing must have a ring ID that differs from the ring ID of the first MS-SPRing. 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 Display the network view to see the subtending ring.
Figure 5-11 shows an example of two subtending MS-SPRings.

Step 9 Complete the "175 Two-Fiber MS-SPRing Acceptance Test" procedure or the "176 Four-Fiber MS-SPRing Acceptance Test" procedure depending on the type of MS-SPRing.
Stop. You have completed this procedure.
