11.6.3 Virtual Wires for External Alarms in Mixed Networks
Virtual wires route external alarms to one or more alarm collection centers in a network. External alarms
can be assigned to virtual wires in networks containing only ONS 15600s or in mixed networks

differently based upon where it is viewed.

The ONS 15600 Virtual Wires window shows 10 virtual wire columns, but 16 are available. The first 12

only support four virtual wires.

Virtual Wires window (accessed in the Alarm Interface Controller [AIC] card view Maintenance
window). The ONS 15454 shows information for only four virtual wires. Because the ONS 15454
