S/UNI®-ATLAS-3200 Telecom Standard Product Data Sheet
Preliminary
•
•
•
Two policing instantiations available per VC. The policed cell streams can be any
combination of user cells, OAM cells, Resource Management, high priority cells or low
priority cells.
Per-PHY policing may also be enabled. Each of 48 PHY devices may have a single leaky
bucket enabled, in addition to the dual leaky bucket of the connection. Violating cells or
frames can be dropped, tagged, or just counted.
When aggregating or terminating a VPC, policing may be performed on the VPC instead of
the individual VCCs.
2.2
Performance Management
•
The S/UNI-ATLAS-3200 device provides OAM-Performance Management functions in each
of its two modes (Ingress Mode and Egress Mode). When an Ingress mode device is used in
conjunction with an Egress mode device, the combination supports bi-directional PM
sessions. A maximum of 512 PM sessions may be simultaneously active in one device. When
using an Ingress mode + Egress mode device, the combination supports upto 512 bi-
directional PM sessions. PM is supported on the F4 and F5 levels. The S/UNI-ATLAS-3200
device provides for the generation of Forward Monitoring and Backward Reporting PM cells
(both segment and end-to-end), the termination of Forward Monitoring and Backward
Reporting cells, and for non-intrusive monitoring of Forward Monitoring and Backward
Reporting cells. The following statistics are collected when terminating or monitoring PM
flows:
