Provisioning the Alarm Interface Controller

Procedure: Enable Intermediate-Path Performance Monitoring

Step 1 If the STS circuit does not exist, create the circuit. (The circui t must pass through the EC -1 or OC-N ca rd
before you can enable IPPM on the circuit.)
Step 2 In CTC, open the card view of an EC-1 or OC-N card that carries the circuit.
Step 3 Select the Provisioning > STS tabs.
Step 4 Click Enable IPPM for the STS you want to monitor.
Step 5 Click Apply.
7.5 Provisioning the Alarm Interface Controller
The Alarm Interface Controller (AIC) card can be provisioned to receive input from, or send output to,
external devices wired to the ONS 15454 backplane. (For d etailed specifications about the AIC, refer to
the Cisco ONS 15454 Troubleshooting and Maintenance Guide.) You can provision the AIC to:
•Generate CTC alarms based on events such as heating or cooling equipment failure , fire ala rms,
smoke detection, and other environmental changes that can damage ONS 15454 e qu ipme nt. Thes e
are called external alarms.
•Turn external devices on or off based on a CTC alarm. For example, you can pr ovision t he AIC t o
turn on an audio or visual device, such as a bell or light, when a critical ONS 15454 alarm occur s.
These triggers are called external controls.
Figure 7-4 shows the flow to and from external devices provisioned thr ough the AIC.
