Step 17:
Node—Choose a node with a DS3XM-12 card installed.
Slot—Choose the slot where a DS3XM-12 card is installed.
DS3 Mapped STS—If applicable, choose Circuit Dest to indicate that the STS is the circuit
destination, or Circuit Source to indicate that the STS is the circuit source.
14, complete the following substeps. If you checked Dual Ring Interconnect for a BLSR, skip
Step 18. If you did not select any of these options, continue with
Primary Node—For a traditional or integrated BLSR-DRI, choose the node where the circuit
interconnects the rings.
Secondary Node—For a traditional or integrated BLSR-DRI, choose the secondary node for the
circuit to interconnect the rings. This route is used if the route on the primary node fails.
Primary Node #2—For a traditional BLSR-DRI where two primary nodes are required to
interconnect rings, choose the second primary node.
Secondary Node #2—For a traditional BLSR-DRI where two secondary nodes are required,
choose the second secondary node.
The first ring is—Choose UPSR or BLSR from the drop-down list.
The second ring is—Choose UPSR or BLSR from the drop-down list.
