7.0 OAM Functions
7.1 OAM Overview
OAM cells are ATM Layer management messages. These are generated by the
host on the segmentation side of the CN8236, and are detected and either
monitored or processed on the reassembly side of the CN8236.
communication technologies. The CN8236 provides internal support for the
detection and generation of OAM traffic, including Performance Monitoring
(PM) OAM.
Recommendation I.610. It also monitors the performance of up to 128 channels,
generating PM-OAM cells according to the same specification.
Refer to ITU-T Recommendation I.610 for complete information on the structures
and functions of OAM cell generation, detection, and processing.
Recommendation I.610.
ATM’s OAM capabilities differentiate it from other less robustly managed
The CN8236 supports the F4 and F5 OAM flows according to ITU-T
