Bit
Name
Action if a logic 1
3
End_pt
Defines the RCMP-200 as an End-to-End termination
point. For VPCs, all cells with VCI=4 are dropped and
processed. For VCCs, all cells with PT=101 are dropped
and processed.
2
Seg_end_pt
Defines the RCMP-200 as a Segment termination point.
For VPCs, all cells with VCI=3 are dropped and
processed. For VCCs, all cells with PT=100 are dropped
and processed.
1
PM_activate
Enables performance management. PM cells are either
sourced or monitored.
0
CC_activate
Enables Continuity Checking. If no user or AIS cell is
received over a 1.5 +/- 0.5 or 2.5 +/- 0.5 (default,
controlled by the AISRDIThresh bit in register 0x19)
second window, a Continuity Check OAM cell is
generated. The CC cell generation interval set by the
CCThresh bit of the Performance Monitoring
Configuration 1 register (0x19).
Upon receipt of an OAM cell, the CRC-10 is checked. If the check sum is
incorrect, the OAM cell is not processed and the global errored OAM cell count is
incremented. Otherwise, further processing is dependent upon the contents of
the OAM Cell Type field.
If a connection is not provisioned as an end point, all incoming OAM cells are
passed to the Output Cell Interface (subject to policing) regardless of whether
the OAM Type or the Function Type fields have defined values. As an option,
OAM cells may be discarded at non flow end-points if the CRC-10 is incorrect. At
flow end-points all OAM cells are terminated, except Activate/Deactivate and
Loopback cells whose handling is specified by the Routing Configuration register.
If the UNDEFtoUP bit of the Routing Configuration register is a logic 1, all
undefined OAM cells are routed to the Microprocessor Cell Interface for further
processing or error logging. If the CNTUNDEF bit in the CRAM Configuration
register is a logic 1, the Errored OAM Cell Count register is incremented for each
cell with an undefined OAM Type or Function Type value.
The PM Configuration field (SA[19:16] = 1101) provides various PM related
functions:
