NTP-A180 Provision a Traditional BLSR/Path Protection Dual-Ring Interconnect
Note To route circuits on the DRI, you must check the Dual Ring Interconnect check box during circuit
creation.
Step 1 Complete the “DLP-A60 Log into CTC” task on page 17-66. If you are already logged in, continue with
Step 2.
Step 2 Complete the following steps if you have not provisioned the BLSR and path protection that you will
interconnect in a traditional DRI. If the BLSR and path protection are created, go to Step 3.
a. To provision and test the BLSR, complete the following:
• “NTP-A40 Provision BLSR Nodes” procedure on page 5-10
• “NTP-A126 Create a BLSR” procedure on page 5-12
• “NTP-A175 Two-Fiber BLSR Acceptance Test” procedure on page 5-13
• “NTP-A176 Four-Fiber BLSR Acceptance Test” procedure on page 5-15
b. To provision and test the path protection, complete the following:
• “NTP-A44 Provision Path Protection Nodes” procedure on page 5-20
• “NTP-A177 Path Protection Acceptance Test” procedure on page 5-22
Step 3 Verify that the DRI interconnect nodes have OC-N cards installed and have fiber connections to the other
interconnect node:
• The OC-N cards that will connect the BLSR and path protection must be installed at the interconnect
nodes. The OC-N cards in the path protection nodes and the interconnect nodes must be the same
type.
• The interconnect nodes must have fiber connections. An example is shown in Figure 5-9.
