Alarm Port The alarm port on the NIU is a flexible interface that closes a circuit when a
specific alarm level becomes active on the Acme Packet 6100. The Acme Packet
6100 features an alarm control signal interface that can be used in a CO
location to indicate when internal alarms are generated. The Acme Packet 6100
uses alarm levels that correspond to three levels of service-disrupting
incidents. When any of the three alarm levels is generated, the corresponding
circuit for that level on the alarm port is closed. The alarm port uses a standard
RJ45 connector.
