Step 5 Verify the conditions:

a.Click the Conditions tab.

b.Click Retrieve.

c.Verify that the following conditions are reported on the node where you invoked the Force Ring switch on the west port:

FORCE-REQ-RING—A Force Switch Request On Ring condition is reported against the span’s working slot on the west side of the node.

RING-SW-EAST—A Ring Switch Active on the east side condition is reported against the working span on the east side of the node.

Note Make sure the Filter button in the lower right corner of the window is off. Click the Node column to sort conditions by node.

RING-SW-WEST—A Ring Switch Active on the west side condition is reported against the working span on the west side of the node.

Step 6 (Optional) If you remapped the K3 byte to run an ONS 15600 SDH MS-SPRing through third-party equipment, check the following condition. Verify a FULLPASSTHR-BI condition reported on other nodes that are not connected to the west side of the node where you invoked the Force Ring switch.

Step 7 Verify the MS-SPRing line status on each node:

a.From the View menu, choose Go to Node View.

b.Click the Maintenance > MS-SPRing tabs.

c.Verify the following:

The line states are shown as Stby/Stby on the west side of the node and Act/Act on the east side of the node where you invoked the Force Ring switch.

The line states are shown as Stby/Stby on the east side of the node and Act/Act on the west side of the node that is connected to the west line of the node where you invoked the Force Ring switch.

The line states are shown as Act/Act on both the east and west sides of the remaining nodes in the ring.

Step 8 From the View menu, choose Go to Network View.

Step 9 Click the Alarms tab.

a.Verify that the alarm filter is not on. See the “DLP-F288 Disable Alarm Filtering” task on page 17-78for instructions.
