between the Acme Packet 4500 and the console adapter.
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 4500. The Acme Packet 4500 features
an alarm control signal interface that can be used in a CO location to indicate when
internal alarms are generated. The Acme Packet 4500 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 following table lists the three alarm levels:
Alarm Type Description
Minor Functionality has been impaired to a small
degree (e.g., a single fan has failed).
Major Pending failures or unexpected events
(e.g., a loss of signal).
Critical Catastrophic condition has occurred (e.g.,
the system is overheating).
The alarm port uses a standard RJ45 connector. Refer to the image of the Acme
Packet 4500's rear panel in the
port.
