Step 2 Click Create.
Step 3 In the Create SDCC Terminations dialog box click the ports where you want to create the DCC termination. To select more than one port, press the Shift key or the Ctrl key.
Note SDCC refers to the Section DCC, which is used for ONS 15327 DCC terminations. The SONET Line DCCs and the Section DCC (when not used as a DCC termination by the ONS 15327) can be provisioned as DCC tunnels. See the "DLP-B313 Create a DCC Tunnel" task.
Step 4 Under Port State, click the Set to IS radio button.
Step 5 Verify that the Disable OSPF on DCC Link check box is unchecked.
Step 6 Click OK.
Note EOC (DCC Termination Failure) and LOS (Loss of Signal) alarms are present until you create all network DCC terminations and put the DCC termination OC-N ports in service.
Note There are four possibilities for the appearance of DCCs: green/solid, green/dashed, gray/solid, gray/dashed. DCC appearance corresponds to the following states: active/routable, active/nonroutable, failed/routable, or failed/nonroutable. Circuit provisioning uses active/routable links. Selecting a node or span in the graphic area displays information about the node and span in the status area.

Note To provision Ethernet ports, see the "DLP-B220 Provision E-Series Ethernet Ports" task or the "DLP-B222 Provision G-Series Ethernet Ports" task.
Step 1 On the node view shelf graphic, double-click the card with the port(s) you want to put in or out of service. The card view appears.
Step 2 Click the Provisioning > Line tabs.
Step 3 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, 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 4 If you change the 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 before changing to IS.
Note A continuously valid signal must be received for the duration of the soak period before the state makes a transition to the IS state. For example, if the soak timer is set for eight hours, and you receive an error after two hours, the timer is reset for another eight-hour period. This cycle continues until an error-free signal is received for an eight-hour period.
Step 5 Click Apply.
Step 6 As needed, repeat this task for each port.

a. Complete the "40 Provision BLSR Nodes" procedure for each node that will be in the BLSR. If you have already provisioned the BLSR, perform this procedure for the subtending node only.
b. Complete the "126 Create a BLSR" procedure. Include the node in Step 3 (the node that will subtend the BLSR) in the BLSR.
Step 6 From the View menu choose Go to the Network View to see the subtending ring.
Stop. You have completed this procedure.
NTP-B48 Subtend a BLSR from a BLSR
Purpose
|
This procedure subtends a BLSR from an existing BLSR.

Note This procedure assumes that all nodes are configured for the BLSR. If you need to add a node to a BLSR, see the "12 Add a BLSR Node" procedure.
Step 1 Log into the node that will subtend the BLSR. See the "DLP-B60 Log into CTC" task for instructions. If you are already logged in, continue with Step 2.
Step 2 Install the OC-N cards that will serve as the BLSR trunk (span) cards if they are not already installed. See the "NTP-B218 Install the Optical and Ethernet Cards" procedure on page 1-23.
Figure 4-6 shows two BLSRs shared by one ONS 15327. 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 BLSR rings, Ring 1 and Ring 2, are provisioned on Node 4. Ring 1 uses cards in Slots 1 and 2, and Ring 2 uses cards in Slots 3 and 4.
Note Although different node IDs are used for the two BLSRs shown in Figure 4-6, nodes in different BLSRs can use the same node ID.

Step 3 Attach fibers from the trunk cards in the subtending node to the BLSR trunk cards on its two neighboring BLSR nodes. In Figure 4-6, Node 4/Slot 3 connects to Node 7/Slot 4, and Node 4/Slot 4 connects to Node 5/Slot 3.
Step 4 Create the DCCs on the first OC-N card that will carry the BLSR. See the "DLP-B253 Provision SONET DCC Terminations" task for instructions.
Step 5 Repeat Step 4 for the second OC-N trunk card that will carry the BLSR.
Step 6 Complete the "40 Provision BLSR Nodes" procedure for each node that will be in the BLSR. If you have already provisioned the BLSR, perform this procedure for the subtending node only.
Step 7 If the subtending BLSR is not already created, complete the "126 Create a BLSR" procedure to provision the new BLSR. The subtending BLSR must have a ring ID that differs from the ring ID of the first BLSR. The subtending node can have one Node ID that is used in both BLSRs, or a different Node ID for each BLSR. For example, the same node can be Node 4 in BLSR 1 and Node 2 in BLSR 2.
Step 8 Display the network view to see the subtending ring.
Step 9 Complete the "175 BLSR Acceptance Test" procedure.
Stop. You have completed this procedure.
