2.7.17 APSCNMIS
The APS Node ID Mismatch alarm occurs when the source node ID contained in the incoming APS
channel K2 byte is not present in the ring map. The APSCNMIS alarm could occur and clear when a
BLSR is being provisioned. If so, you can disregard the temporary occurrence. If the APSCNMIS
remains, the alarm clears when a K byte with a valid source node ID is received.

to change one node ID number so that each node ID is unique.
If the node names shown in the network view do not correlate with the node IDs, log into each
node and click the Provisioning > BLSR tabs. The BLSR window shows the node ID of the
login node.
Applying and removing a lockout on a span causes the ONS node to generate a new K byte. The
APSCNMIS alarm clears when the node receives a K byte containing the correct node ID.
