Using Cisco Transport Controller 3

3.12.3 External Output Controls

Use external controls, or office alarms, to drive visual or audible devices such as bells and lights. The alarm-triggering conditions for the external controls can be the user-defined external input alarms (virtual wire), local severity-based alarms (e.g. trigger when any Major alarm happens), or remote severity-based alarms.

Procedure: Provision External Controls

Step 1 Wire the external control relays to the ALARM RJ-45 connector on the MIC.

Step 2 In CTC, log into the node and display the XTC card view.

Step 3 Click the External Controls subtab as shown in Figure 3-25.

Step 4 Complete the following fields for each external control wired to the Alarm connector on the MIC:

Enabled— Click the box to activate the fields for alarm input number 1 or 2.

Trigger Type— Select a trigger type: a local Minor, Major, or Critical alarm; a remote Minor, Major, or Critical alarm; or a virtual wire activation.

Description— Enter a description.

Step 5 To provision additional controls, complete Step 4 for each additional device.

Step 6 Click Apply.
