Connecting Cisco ONS 15454 AIC-I Alarm Cables
This document contains information about connecting the cables for the external alarm contacts 
provided by the AIC-I card. Use this document in conjunction with the Cisco ONS 15454 Procedure 
Guide
 and the Cisco ONS 15454 Reference Guide.
This document contains the following sections:
Alarm Interface Controller-International Card
 
The optional Alarm Interface Controller-International (AIC-I) card provides customer-defined alarm 
input/output (I/O) and supports user data and local and express orderwire. It provides 12 customer 
defined input and 4 customer defined input/output contacts. The physical connections are via the 
backplane wire-wrap pin terminals. A power monitoring function monitors the supply voltage (-48VDC) 
for the ANSI platform. 
User-Defined Alarms
The AIC-I card provides input/output alarm contact closures. You can define up to twelve external alarm 
inputs and four external alarm inputs/outputs (user configurable). The physical connections are made 
using the backplane wire-wrap pins. The alarms are defined using CTC and TL1. For instructions, refer 
to the Cisco ONS 15454 Procedure Guide
LEDs on the front panel of the AIC-I indicate the status of the alarm lines, one LED representing all the 
inputs and one LED representing all the outputs. External alarms (input contacts) are typically used for 
external sensors such as open doors, temperature sensors, flood sensors, and other environmental 
conditions. External controls (output contacts) are typically used to drive visual or audible devices such 
as bells and lights, but they can control other devices such as generators, heaters, and fans.
