AIC NETWORK MODULE LIGHT EMITTING DIODES
The AIC follows the convention of other network modules for light emitting diode (LED) operation. There are two LEDs—enable (EN) and status
(STAT). Table 2 lists the network-module state indicated by the LEDs, and Figure 5 shows the placement of the LEDs.

INTERFACING THE AIC
When the AIC is incorporated into a DCN-Operations Support Network router, all the AIC contact-closure alarms are routed and reported through
the same network and systems as the DCN router. This setup facilitates continued use of the existing OSS and its associated networks. A Cisco
router with an AIC sends TL-1 or SNMP messages to the OSS autonomously or in response to TL-1 or SNMP commands from the OSS, as shown
in Figure 6.
