S/UNI®-ATLAS-3200 Telecom Standard Product Data Sheet
Preliminary
Name
Description
generation is forced (using either the send_RDI table bits or the per-phy RDI
register bits) or generated by the CC_AIS_RDI process, the contents of the
Generated OAM Defect Type field will be used. If the connection is an F4
being split out into F5s, then this field is used to determine the Defect Type
of F5 AIS and RDI cells sent due to F4 End-to-End AIS declaration.
In the case of received RDI cells, the defect type is simply stored for future
retrieval. Defect types from RDI cells will not be stored if End-to-end AIS
alarm has been declared, and will be overwritten on the arrival of AIS cells,
so this field is only valid for RDI cells if End-to-end RDI alarm is declared
and End-to-end AIS alarm is not.
Received Segment Defect
Location [127:0]
This field is used to store the Defect Location from a segment AIS or RDI
cell.
In the case of received AIS cells, this field is used in RDI cells generated
due to Segment AIS declaration via the AUTO_RDI function. If RDI cell
generation is forced (using either the send_RDI table bits or the per-phy RDI
register bits) or generated by the CC_AIS_RDI process, the contents of the
global Defect Location registers will be used. If the connection is an F4
being split out into F5s, then this field is used to determine the Defect
Location of F5 AIS and RDI cells sent due to F4 Segment AIS declaration.
In the case of received RDI cells, the defect location is simply stored for
future retrieval. Defect locations from RDI cells will not be stored if Segment
AIS alarm has been declared, and will be overwritten on the arrival of AIS
cells, so this field is only valid for RDI cells if Segment RDI alarm is declared
and Segment AIS alarm is not.
Received Segment AIS
Defect Type [7:0]
This field is used to store the Defect Type from a received segment AIS or
RDI cell.
In the case of received AIS cells, this field is used in segment RDI cells
generated due to Segment AIS declaration via the AUTO_RDI function. If
RDI cell generation is forced (using either the send_RDI table bits or the
per-phy RDI register bits) or generated by the CC_AIS_RDI process, the
contents of the Generated OAM Defect Type field will be used. If the
connection is an F4 being split out into F5s, then this field is used to
determine the Defect Location of F5 AIS and RDI cells sent due to F4
Segment AIS declaration.
In the case of received RDI cells, the defect type is simply stored for future
retrieval. Defect types from RDI cells will not be stored if Segment AIS
alarm has been declared, and will be overwritten on the arrival of AIS cells,
so this field is only valid for RDI cells if Segment RDI alarm is declared and
Segment AIS alarm is not.
