DLP-A91 BLSR Switch Test
Step 4 Initiate a Force Ring switch on the west port:
a. Right-click any BLSR node west port and choose Set West Protection Operation. Figure 19-2 on
page 19-11 shows an example. (To move a graphic icon, click it, then press Ctrl while you drag and
drop it to a new location.)
Note For two-fiber BLSRs, the squares on the node icons represent the BLSR working and protect
channels. You can right-click either channel. For four-fiber BLSRs, the squares represent
ports. Right-click either working or protect port.
b. In the Set West Protection Operation dialog box, choose FORCE RING from the drop-down list.
c. Click OK.
d. Click Yes in the two Confirm BLSR Operation dialog boxes that appear.
On the network view graphic, an F appears on the BLSR channel where you invoked the Force Ring
switch. The BLSR span lines turn purple where the switch was invoked, and all span lines between
other BLSR nodes turn green.
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.
d. Verify that the following conditions are reported on the node that is connected to the west line of the
node where you performed the switch:
• FE-FRCDWKSWPR-RING—A Far-End Working Facility Forced to Switch to Protection
condition is reported against the working span on the east side of the 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 15454 BLSR through third-party equipment,
check the following condition. Verify that a FULLPASSTHR-BI condition is 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 BLSR line status on each node:
a. From the View menu choose Go to Node View.
b. Click the Maintenance > BLSR 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.
