Ethernet Alarm Indication Signal Overview
ACX Series routers support ITU-T Y.1731 Ethernet Alarm Indication Signal function
(ETH-AIS) to provide fault management for service providers. ETH-AIS enables you to
suppress alarms when a fault condition is detected. Using ETH-AIS, an administrator
can differentiate between faults at customer level or faults at provider level.
The advantage of ETH-AIS is:
•
Customers need not raise alarms due to lower level failures.
•
Customers can get refund based on service unavailability.
When a fault condition is detected, a maintenance end point (MEP) generates ETH-AIS
packets to the configured client levels for a specified duration until the fault condition is
cleared. Any MEP configured to generate ETH-AIS packets signals to a level higher than
