Tip
Alarm Interface Controller Network Module
The AIC network module, shown in Figure 29-1, supports 64 alarm inputs. Fifty-six alarm inputs are 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.
The AIC network module is connected to the network using four high-density SCSI-type connectors on the front panel.

Connecting the AIC Network Module to the Network
An AIC network module provides four 50-pin receptacles. Use cables that have male Micro DB-50 connectors at both ends with all conductors straight-wired. Central office equipment is cabled to the patch panel, and then cross-connected to the AIC cable.
Two different patch panels can be used. The AIC-1 patch panel terminates one AIC and has voltage terminations with lugs and fuses for voltage monitoring. The AIC-2 patch panel terminates up to two AICs or 128 contact closure points
See Figure 29-2 through Figure 29-6 for examples of the AIC connections to the patch panels.
See the AIC data sheet on www.cisco.com for recommended patch panel and cable vendors.

Ports are numbered from right to left and from bottom to top, as labeled on the module rear panel. Pinouts for the AIC-1 patch panel are shown in Table 29-1. The connector 3 voltage monitor pinouts for AIC-1 are shown in Table 29-2. Pinouts for the AIC-2 patch panel are shown in Table 29-3.
Cables are not provided with the network module. For ordering information, see the "Obtaining Technical Assistance" section on page xi.

AIC Network Module LEDs
This section describes AIC network module LEDs. (See Figure 29-7.)
All network modules have an enable (EN) LED. This LED indicates that the module is receiving power from the router chassis.
The AIC network module also has a status (STAT) LED, which is a software-controlled bicolor (green and orange) LED. Both the EN and STAT LEDs turn on when the router is powered up, recycled, or power-cycled, or the AIC is hot-swapped. When the AIC starts to boot up, the STAT LED is initially turned off. It turns green when the software has initialized, has passed POST, and has established communication with IOS.
The STAT LED turns from green to orange when POST has failed or when the software encounters any other fatal fault in its firmware during normal operation.
Table 29-4 defines the state of the card with respect to the states of the LEDs.
