Adaptive Bandwidth Notification Overview
Adaptive Bandwidth Notification (ABN), also known as Ethernet Operation and
Maintenance (EOAM), enables third party applications to learn about bandwidth
changes in a radio link when ACM is active. Once ABN is enabled, the radio unit
reports bandwidth information to upstream third-party switches.
The ABN entity creates a logical relationship between a radio interface or a logical
group of radio interfaces, called the Monitored Interface, and an Ethernet
interface or a logical group of Ethernet interface, called the Control Interface.
When bandwidth degrades from the nominal value in the Monitored Interface,
messages relaying the actual bandwidth values are periodically sent over the
Control Interface. A termination message is sent once the bandwidth returns to its
nominal level.
