DLP-D371 View the MS-SPRing Squelch Table
Step 1 In node view, click the Provisioning > MS-SPR tabs.
Step 2 Click Squelch Table. In the MS-SPR Squelch Table window, you can view the following information:
• VC4 Number—Shows the MS-SPRing VC4 numbers.
• West-Source—If traffic is received by the node on its west span, the MS-SPRing node ID of the
source appears. (To view the MS-SPRing node IDs for all nodes in the ring, click Ring Map.)
• West-Dest—If traffic is sent on the node’s west span, the MS-SPRing node ID of the destination
appears.
• East-Source—If traffic is received by the node on its east span, the MS-SPRing node ID of the
source appears.
• East-Dest—If traffic is sent on the node’s east span, the MS-SPRing node ID of the destination
appears.
Note MS-SPRing squelching is performed on VC4s that carry high-order circuits only. VC4s
carrying low-order or stitched Ethernet circuits do not have entries in the squelch table.
Step 3 Return to your originating procedure (NTP).
Purpose This task allows you to view the MS-SPRing squelch table for an
ONS 15454 SDH MS-SPRing node. Squelching replaces traffic by the
appropriate path AIS; it prevents traffic misconnections when a working
channel service contends for access to a protection channel time slot
carrying extra traffic. The table shows VC4s in the MS-SPRing squelched
for every isolated node.
