Cisco Cisco IOS Software Release 12.2(2)XG

This feature module describes the software support for the Network Module-Alarm Interface 
Controller-64, Contact Closure Network Module or NM-AIC-64, Contact Closure Network Module. It 
includes information on the benefits of the new feature, supported platforms, related documents, and so 
on.

This document includes the following sections:

The AIC NM is an optional card that expands network management capabilities for customer-defined 
alarms. The AIC has its own CPU that communicates with the router and external media through serial 
communication channels. The AIC reduces service provider and enterprise operating costs by providing 
a flexible, low-cost network solution for migrating existing data communications networks (DCNs) to 
IP-based DCNs. The AIC provides its users with a single “box” solution because it can be configured in 
the same router along with other Operation, Alarm, Maintenance, and Provisioning (OAM&P) 
interfaces.

More than one AIC can be installed per router. For example, a Cisco 3662 can have up to five AICs, and 
its sixth NM slot can be used for router communication. The Cisco 3640 can have up to three AICs, with 
the fourth NM slot reserved for communication, and so forth.

This feature was introduced on the Cisco 2600 series and Cisco 3600 
series platforms.
