Alarm Interface Controller Network Module
The AIC network module, shown in
discrete and can operate on dry contact closure when a patch panel is used. The last eight alarm inputs
can be provisioned to accept analog inputs. The AIC network module has 16 control relay outputs.
The AIC network module can be connected to a patch panel. The patch panel provides the bias to the
circuit.
The analog alarm inputs can be configured to monitor either DC voltage or current. The AIC can measure
voltage from –60 to 60 V or current from 0 to 20 mA. The control relay can be operated to turn an
external device on or off. When an event is detected, notification messages are sent to the Operations
Support System (OSS) in the network operation center (NOC). These alarm inputs are configured in
Cisco IOS software. Some reportable events include:

The AIC network module converts relay contact alarm signals to TL1 and SNMP message formats,
providing TL1 over TCP/IP and SNMP protocols. All the contact closure-related alarms are routed and
reported through the existing OSS and the associated OSS networks. With this network module, the
Cisco router sends the TL1 or SNMP messages to the OSS autonomously or in response to TL1 or SNMP
commands from the OSS.
