CHAPTER 10
G.8032 and CFM Support for Microwave Adaptive
Bandwidth
The G.8032 and CFM Support for Microwave Adaptive Bandwidth feature enables the G.8032 Ethernet
Protection Ring (ERP) mechanism to be used as a trigger in response to bandwidth degradation occurrences
(such as a signal degradation [SD] indicator) on microwave links. Ethernet Connectivity Fault Management
(CFM) interacts with the microwave transceiver to continuously check the quality and the bandwidth of the
microwave link. When microwave link degradation (based on the configured service level agreement [SLA]
in use) is detected, CFM notifies the Embedded Event Manager (EEM), which in turn notifies a mechanism
such as, G.8032 ERP. G.8032 ERP ensures that the degraded microwave link is bypassed and no longer
used. The degraded microwave link can still be used by one or more of the G.8032 ERP instances. Only the
affected G.8032 ERP instances are switched to alternate link.
